Files

A class used to load remote content to an Element. Sample usage:

Ext.get('el').load({
    url: 'myPage.php',
    scripts: true,
    params: {
        id: 1
    }
});

In general this class will not be instanced directly, rather the Ext.Element.load method will be used.

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'); }
        }
    }
});

    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
      });

    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}
      });

                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',

                          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}
                            });
