DataTable Class

Extends DataTable.Base

Defined in: datatable/js/base.js:16

Module: datatable-base
Parent Module: datatable

Available since 3.5.0

A Widget for displaying tabular data. Before feature modules are use()d, this class is functionally equivalent to DataTable.Base. However, feature modules can modify this class in non-destructive ways, expanding the API and functionality.

This is the primary DataTable class. Out of the box, it provides the ability to dynamically generate an HTML table from a set of column configurations and row data. But feature module inclusion can add table sorting, pagintaion, highlighting, selection, and more.


// The functionality of this table would require additional modules be use()d,
// but the feature APIs are aggregated onto Y.DataTable.
// (Snippet is for illustration. Not all features are available today.)
var table = new Y.DataTable({
    columns: [
        { type: 'checkbox', defaultChecked: true },
        { key: 'firstName', sortable: true, resizable: true },
        { key: 'lastName', sortable: true },
        { key: 'role', formatter: toRoleName }
    ],
    data: {
        source: 'http://myserver.com/service/json',
        type: 'json',
        schema: {
            resultListLocator: 'results.users',
            fields: [
                'username',
                'firstName',
                'lastName',
                { key: 'role', type: 'number' }
            ]
        }
    },
    recordType: UserModel,
    pagedData: {
        location: 'footer',
        pageSizes: [20, 50, 'all'],
        rowsPerPage: 20,
        pageLinks: 5
    },
    editable: true
});

Column Configuration

The column configurations are set in the form of an array of objects, where each object corresponds to a column. For columns populated directly from the row data, a 'key' property is required to bind the column to that property or attribute in the row data.

Not all columns need to relate to row data, nor do all properties or attributes of the row data need to have a corresponding column. However, only those columns included in the columns configuration attribute will be rendered.

Other column configuration properties are supported by the configured headerView, bodyView, footerView classes as well as any features added by plugins or class extensions. See the description of DataTable.HeaderView, DataTable.BodyView, and other DataTable feature classes to see what column properties they support.

Some examples of column configurations would be:


// Basic
var columns = [{ key: 'firstName' }, { key: 'lastName' }, { key: 'age' }];

// For columns without any additional configuration, strings can be used
var columns = ['firstName', 'lastName', 'age'];

// Multi-row column headers (see DataTable.HeaderView for details)
var columns = [
    {
        label: 'Name',
        children: [
            { key: 'firstName' },
            { key: 'lastName' }
        ]
    },
    'age' // mixing and matching objects and strings is ok
];

// Including columns that are not related 1:1 to row data fields/attributes
// (See DataTable.BodyView for details)
var columns = [
    {
        label: 'Name', // Needed for the column header
        formatter: function (o) {
            // Fill the column cells with data from firstName and lastName
            if (o.data.age > 55) {
                o.className += ' senior';
            }
            return o.data.lastName + ', ' + o.data.firstName;
        }
    },
    'age'
];

// Columns that include feature configurations (for illustration; not all
// features are available today).
var columns = [
    { type: 'checkbox', defaultChecked: true },
    { key: 'firstName', sortable: true, resizable: true, min-width: '300px' },
    { key: 'lastName', sortable: true, resizable: true, min-width: '300px' },
    { key: 'age', emptyCellValue: 'unknown' }
];

Row Data Configuration

The data configuration attribute is responsible for housing the data objects that will be rendered as rows. You can provide this information in two ways by default:

An array of simple objects with key:value pairs
A ModelList of Base-based class instances (presumably Model subclass instances)

If an array of objects is passed, it will be translated into a ModelList filled with instances of the class provided to the recordType attribute. This attribute can also create a custom Model subclass from an array of field names or an object of attribute configurations. If no recordType is provided, one will be created for you from available information (see _initRecordType). Providing either your own ModelList instance for data, or at least Model class for recordType, is the best way to control client-server synchronization when modifying data on the client side.

The ModelList instance that manages the table's data is available in the data property on the DataTable instance.

Rendering

Table rendering is a collaborative process between the DataTable and its configured headerView, bodyView, and footerView. The DataTable renders the <table> and <caption>, but the contents of the table are delegated to instances of the classes provided to the headerView, bodyView, and footerView attributes. If any of these attributes is unset, that portion of the table won't be rendered.

DataTable.Base assigns the default headerView to Y.DataTable.HeaderView and the default bodyView to Y.DataTable.BodyView, though either can be overridden for custom rendering. No default footerView is assigned. See those classes for more details about how they operate.

This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

`_filterUIEvent`

(

evt

)

Boolean private

Inherited from Widget: widget/js/WidgetUIEvents.js:117

This method is used to determine if we should fire the UI Event or not. The default implementation makes sure that for nested delegates (nested unrelated widgets), we don't fire the UI event listener more than once at each level.

For example, without the additional filter, if you have nested widgets, each widget will have a delegate listener. If you click on the inner widget, the inner delegate listener's filter will match once, but the outer will match twice (based on delegate's design) - once for the inner widget, and once for the outer.

Parameters:

evt DOMEventFacade

Returns:

Boolean: true if it's OK to fire the custom UI event, false if not.

If the recordType attribute is not set, this method attempts to set a default value.

It tries the following methods to determine a default:

If the data attribute is set with a ModelList with a model property, that class is used.
If the data attribute is set with a non-empty ModelList, the constructor of the first item is used.
If the data attribute is set with a non-empty array and the first item is a Base subclass, its constructor is used.
If the data attribute is set with a non-empty array a custom Model subclass is generated using the keys of the first item as its ATTRS.
If the _columnMap property has keys, a custom Model subclass is generated using those keys as its ATTRS.

Of none of those are successful, it subscribes to the change events for columns, recordType, and data to try again.

If defaulting the recordType and the current _columnMap property is empty, it will call _initColumns.

)

protected

Provided by the datatable-core module.

Defined in datatable/js/core.js:1203

Available since 3.5.0

Iterates the array of column configurations to capture all columns with a key property. Columns that are represented as strings will be replaced with objects with the string assigned as the key property. If a column has a children property, it will be iterated, adding any nested column keys to the returned map. There is no limit to the levels of nesting.

All columns are assigned a _yuid stamp and _id property corresponding to the column's configured name or key property with any spaces replaced with dashes. If the same name or key appears in multiple columns, subsequent appearances will have their _id appended with an incrementing number (e.g. if column "foo" is included in the columns attribute twice, the first will get _id of "foo", and the second an _id of "foo1"). Columns that are children of other columns will have the _parent property added, assigned the column object to which they belong.

`addAttr`

(

name
config
lazy

)

Object chainable

Inherited from AttributeCore: attribute/js/AttributeCore.js:124

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>

The initial value to set on the attribute

valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>

Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.

writeOnce <boolean> or <string>

Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>

Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

name String

The name of the attribute.
config Object

An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.
lazy Boolean

(optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object: A reference to the host object.

`addAttrs`

(

cfgs
values
lazy

)

Object chainable

Inherited from AttributeCore: attribute/js/AttributeCore.js:708

Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

Returns:

Object: A reference to the host object.

`addColumn`

(

config
[index]

)

DataTable chainable

Provided by the datatable-mutable module.

Defined in datatable/js/mutable.js:60

Available since 3.5.0

Adds the column configuration to the DataTable's columns configuration. If the index parameter is supplied, it is injected at that index. If the table has nested headers, inject a subcolumn by passing an array of indexes to identify the new column's final location.

The index parameter is required if adding a nested column.

This method is a convienience method for fetching the DataTable's columns attribute, updating it, and calling table.set('columns', _updatedColumnsDefs_)

For example:

// Becomes last column
table.addColumn('name');

// Inserted after the current second column, moving the current third column
// to index 4
table.addColumn({ key: 'price', formatter: currencyFormatter }, 2 );

// Insert a new column in a set of headers three rows deep.  The index array
// translates to
// [ 2, --  in the third column's children
//   1, --  in the second child's children
//   3 ] -- as the fourth child column
table.addColumn({ key: 'age', sortable: true }, [ 2, 1, 3 ]);

Parameters:

config Object | String

The new column configuration object
[index] Number | Number[] optional

the insertion index

Returns:

DataTable:

DataTable chainable

Provided by the datatable-mutable module.

Defined in datatable/js/mutable.js:198

Available since 3.5.0

Adds a new record to the DataTable's data ModelList. Record data can be an object of field values or an instance of the DataTable's configured recordType class.

This relays all parameters to the data ModelList's add method.

If a configuration object is passed as a second argument, and that object has sync: true set, the underlying Model will be save()d.

If the DataTable's autoSync attribute is set to true, the additional argument is not needed.

If syncing and the last argument is a function, that function will be used as a callback to the Model's save() method.

Parameters:

data Object

The data or Model instance for the new record
[config] Object optional

Configuration to pass along
[callback] Function optional

Callback function for Model's save()
- err Error | Null
  
  If an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be null.
- response Any
  
  The server's response. This value will be passed to the parse() method, which is expected to parse it and return an attribute hash.

Returns:

DataTable:

DataTable chainable

Provided by the datatable-mutable module.

Defined in datatable/js/mutable.js:552

Available since 3.5.0

Adds an array of new records to the DataTable's data ModelList. Record data can be an array of objects containing field values or an array of instance of the DataTable's configured recordType class.

This relays all parameters to the data ModelList's add method.

Technically, this is an alias to addRow, but please use the appropriately named method for readability.

If a configuration object is passed as a second argument, and that object has sync: true set, the underlying Models will be save()d.

If the DataTable's autoSync attribute is set to true, the additional argument is not needed.

If syncing and the last argument is a function, that function will be used as a callback to each Model's save() method.

Parameters:

data Object[]

The data or Model instances to add
[config] Object optional

Configuration to pass along
[callback] Function optional

Callback function for each Model's save()
- err Error | Null
  
  If an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be null.
- response Any
  
  The server's response. This value will be passed to the parse() method, which is expected to parse it and return an attribute hash.

Returns:

Parameters:

type String | Object

The type of the event, or an object that contains a 'type' property.
arguments Object*

an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

EventHandle

Inherited from EventTarget: event-custom/js/event-target.js:192

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.

Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name.

To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback, or pass an array of event names as the first argument to subscribe to all listed events with the same callback.

Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

type String

The name of the event
fn Function

The callback to execute in response to the event

Available since 3.5.0

The class or object to use for rendering the <tbody> or <tbody>s and all data row content for the table. This attribute is responsible for populating the the instance's body property.

If a class constructor (function) is passed, an instance of that clas will be created at render() time and assigned to this.body. If an object is passed, body will be set immediately.

Valid objects or classes will have a render() method, though it is recommended that they be subclasses of Y.Base or Y.View. If the object or class supports events, its addTarget() method will be called to bubble its events to this instance.

The core implementaion does not define a default bodyView. Classes built from this extension should define a default.

Fires event `bodyViewChange`

Fires when the value for the configuration attribute bodyView is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

`columns`

Object[] | String[]

Provided by the datatable-core module.

Defined in datatable/js/core.js:59

Available since 3.5.0

Columns to include in the rendered table.

If omitted, the attributes on the configured recordType or the first item in the data collection will be used as a source.

This attribute takes an array of strings or objects (mixing the two is fine). Each string or object is considered a column to be rendered. Strings are converted to objects, so columns: ['first', 'last'] becomes columns: [{ key: 'first' }, { key: 'last' }].

DataTable.Core only concerns itself with a few properties of columns. All other properties are for use by the headerView, bodyView, footerView, and any class extensions or plugins on the final class or instance. See the descriptions of the view classes and feature class extensions and plugins for details on the specific properties they read or add to column definitions.

The properties that are referenced or assigned are:

key - Used to identify the record field/attribute containing content for this column. Also used to create a default Model if no recordType or data are provided during construction. If name is not specified, this is assigned to the _id property (with added incrementer if the key is used by multiple columns).
children - Traversed to initialize nested column objects
name - Used in place of, or in addition to, the key. Useful for columns that aren't bound to a field/attribute in the record data. This is assigned to the _id property.
id - For backward compatibility. Implementers can specify the id of the header cell. This should be avoided, if possible, to avoid the potential for creating DOM elements with duplicate IDs.
field - For backward compatibility. Implementers should use name.
_id - Assigned unique-within-this-instance id for a column. By order of preference, assumes the value of name, key, id, or _yuid. This is used by the bodyView and headerView as well as feature module as a means to identify a specific column without ambiguity (such as multiple columns using the same key.
_yuid - Guid stamp assigned to the column object.
_parent - Assigned to all child columns, referencing their parent column.

Default: (from `recordType` ATTRS or first item in the `data`)

`recordType`

Function

Provided by the datatable-core module.

Defined in datatable/js/core.js:112

Available since 3.5.0

Model subclass to use as the model for the ModelList stored in the data attribute.

If not provided, it will try really hard to figure out what to use. The following attempts will be made to set a default value:

If the data attribute is set with a ModelList instance and its model property is set, that will be used.
If the data attribute is set with a ModelList instance, and its model property is unset, but it is populated, the ATTRS of the `constructor of the first item will be used.
If the data attribute is set with a non-empty array, a Model subclass will be generated using the keys of the first item as its ATTRS (see the _createRecordClass method).
If the columns attribute is set, a Model subclass will be generated using the columns defined with a key. This is least desirable because columns can be duplicated or nested in a way that's not parsable.
If neither data nor columns is set or populated, a change event subscriber will listen for the first to be changed and try all over again.
