Files

Provides for repetitive polling of the server at distinct intervals. The initial request for data originates from the client, and then is responded to by the server.

All configurations for the PollingProvider should be generated by the server-side API portion of the Ext.Direct stack.

An instance of PollingProvider may be created directly via the new keyword or by simply specifying type = 'polling'. For example:

var pollA = new Ext.direct.PollingProvider({
    type:'polling',
    url: 'php/pollA.php',
});
Ext.direct.Manager.addProvider(pollA);
pollA.disconnect();

Ext.direct.Manager.addProvider(
    {
        type:'polling',
        url: 'php/pollB.php',
        id: 'pollB-provider'
    }
);
var pollB = Ext.direct.Manager.getProvider('pollB-provider');

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.

DOM events from Ext JS Components

While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually only done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a child element of a Component, we need to specify the element option to identify the Component property to add a DOM listener to:

new Ext.panel.Panel({
    width: 400,
    height: 200,
    dockedItems: [{
        xtype: 'toolbar'
    }],
    listeners: {
        click: {
            element: 'el', //bind to the underlying el property on the panel
            fn: function(){ console.log('click el'); }
        },
        dblclick: {
            element: 'body', //bind to the underlying body property on the panel
            fn: function(){ console.log('dblclick body'); }
        }
    }
});

Instance methods

Adds the specified events to the list of events which this Observable may fire. ...

Adds the specified events to the list of events which this Observable may fire.

Available since: 1.1.0

Parameters

  • o : Object/String

    Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters. Usage:

    this.addEvents({
        storeloaded: true,
        storecleared: true
    });
    
  • more : String... (optional)

    Additional event names if multiple event names are being passed as separate parameters. Usage:

    this.addEvents('storeloaded', 'storecleared');
    
...

Available since: 4.0.6

Parameters

Returns

( eventName, fn, [scope], [options] )
Appends an event handler to this object. ...

Appends an event handler to this object.

Available since: 1.1.0

Parameters

  • eventName : String

    The name of the event to listen for. May also be an object who's property names are event names.

  • fn : Function

    The method the event invokes. Will be called with arguments given to fireEvent plus the options parameter described below.

  • scope : Object (optional)

    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

  • options : Object (optional)

    An object containing handler configuration.

    Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

    This object may contain any of the following properties:

    • scope : Object

      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

    • delay : Number

      The number of milliseconds to delay the invocation of the handler after the event fires.

    • single : Boolean

      True to add a handler to handle just the next firing of the event, and then remove itself.

    • buffer : Number

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

    • target : Observable

      Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

    • element : String

      This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

      This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

      new Ext.panel.Panel({
          title: 'The title',
          listeners: {
              click: this.handlePanelClick,
              element: 'body'
          }
      });
      

    Combining Options

    Using the options argument, it is possible to combine different types of listeners:

    A delayed, one-time listener.

    myPanel.on('hide', this.handleClick, this, {
        single: true,
        delay: 100
    });
    

    Attaching multiple handlers in 1 call

    The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

    myGridPanel.on({
        cellClick: this.onCellClick,
        mouseover: this.onMouseOver,
        mouseout: this.onMouseOut,
        scope: this // Important. Ensure "this" is correct during handler execution
    });
    

    One can also specify options for each event handler separately:

    myGridPanel.on({
        cellClick: {fn: this.onCellClick, scope: this, single: true},
        mouseover: {fn: panel.onMouseOver, scope: panel}
    });

    Available since: 4.0.0

    Parameters

    • item : Ext.util.Observable/Ext.Element

      The item to which to add a listener/listeners.

    • ename : Object/String

      The event name, or an object containing event name properties.

      If the ename parameter was an event name, this is the handler function.

    • scope : Object (optional)

      If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

    • opt : Object (optional)

              Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

              Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

              This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

              Example:

              Ext.override(Ext.form.field.Base, {
                  //  Add functionality to Field's initComponent to enable the change event to bubble
                  initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
                      this.enableBubble('change');
                  }),
              
                  //  We know that we want Field's events to bubble directly to the FormPanel.
                  getBubbleTarget : function() {
                      if (!this.formPanel) {
                          this.formPanel = this.findParentByType('form');
                      }
                      return this.formPanel;
                  }
              });
              
              var myForm = new Ext.formPanel({
                  title: 'User Details',
                  items: [{
                      ...

                  listeners: {
                      change: function() {
                          // Title goes red if form has been modified.
                          myForm.header.setStyle('color', 'red');

                      Available since: 1.1.0

                      Parameters

                      • eventName : String

                        The name of the event to listen for. May also be an object who's property names are event names.

                      • fn : Function

                        The method the event invokes. Will be called with arguments given to fireEvent plus the options parameter described below.

                      • scope : Object (optional)

                        The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

                      • options : Object (optional)

                        An object containing handler configuration.

                        Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

                        This object may contain any of the following properties:

                        • scope : Object

                          The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

                        • delay : Number

                          The number of milliseconds to delay the invocation of the handler after the event fires.

                        • single : Boolean

                          True to add a handler to handle just the next firing of the event, and then remove itself.

                        • buffer : Number

                          Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

                        • target : Observable

                          Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

                        • element : String

                          This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

                          This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

                          new Ext.panel.Panel({
                              title: 'The title',
                              listeners: {
                                  click: this.handlePanelClick,
                                  element: 'body'
                              }
                          });
                          

                        Combining Options

                        Using the options argument, it is possible to combine different types of listeners:

                        A delayed, one-time listener.

                        myPanel.on('hide', this.handleClick, this, {
                            single: true,
                            delay: 100
                        });
                        

                        Attaching multiple handlers in 1 call

                        The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

                        myGridPanel.on({
                            cellClick: this.onCellClick,
                            mouseover: this.onMouseOver,
                            mouseout: this.onMouseOut,
                            scope: this // Important. Ensure "this" is correct during handler execution
                        });
                        

                        One can also specify options for each event handler separately:

                        myGridPanel.on({
                            cellClick: {fn: this.onCellClick, scope: this, single: true},
                            mouseover: {fn: panel.onMouseOver, scope: panel}
                        });
