Files

The Connection class encapsulates a connection to the page's originating domain, allowing requests to be made either to a configured URL, or to a URL specified at request time.

Requests made by this class are asynchronous, and will return immediately. No data from the server will be available to the statement immediately following the request call. To process returned data, use a success callback in the request options object, or an event listener.

File Uploads

File uploads are not performed using normal "Ajax" techniques, that is they are not performed using XMLHttpRequests. Instead the form is submitted in the standard manner with the DOM <form> element temporarily modified to have its target set to refer to a dynamically generated, hidden <iframe> which is inserted into the document but removed after the return data has been gathered.

The server response is parsed by the browser to create the document for the IFRAME. If the server is using JSON to send the return object, then the Content-Type header must be set to "text/html" in order to tell the browser to insert the text unchanged into the document body.

Characters which are significant to an HTML parser must be sent as HTML entities, so encode < as &lt;, & as &amp; etc.

The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a responseText property in order to conform to the requirements of event handlers and callbacks.

Be aware that file upload packets are sent with the content type multipart/form and some server technologies (notably JEE) may require some custom processing in order to retrieve parameter names and parameter values from the packet content.

Also note that it's not possible to check the response code of the hidden iframe, so the success handler will ALWAYS fire.

          Available since: 1.1.0

          This method has been deprecated since 2.0

          It's no longer needed to add events before firing.

          Parameters

          • eventNames : 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.

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

          Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.

          Combining Options

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

          A delayed, one-time listener:

          container.on('tap', this.handleTap, 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:

          container.on({
              tap  : this.onTap,
              swipe: this.onSwipe,
          
              scope: this // Important. Ensure "this" is correct during handler execution
          });
          

          One can also specify options for each event handler separately:

          container.on({
              tap  : { fn: this.onTap, scope: this, single: true },
              swipe: { fn: button.onSwipe, scope: button }
          });
          

          See the Events Guide for more.

          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.

            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.

            • order : String

              The order of when the listener should be added into the listener queue.

              If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

              Available options are before, current and after. Defaults to current.

            • buffer : Number

              Causes the handler to be 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.

            • element : String

              Allows you to add a listener onto a element of this component using the elements reference.

              Ext.create('Ext.Component', {
                  listeners: {
                      element: 'element',
                      tap: function() {
                          console.log('element tap!');
                      }
                  }
              });
              

              All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

            • delegate : String

              Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

              // Create a container with a two children; a button and a toolbar
              var container = Ext.create('Ext.Container', {
                  items: [
                      {
                         xtype: 'toolbar',
                         docked: 'top',
                         title: 'My Toolbar'
                      },
                      {
                         xtype: 'button',
                         text: 'My Button'
                      }
                  ]
              });
              
              container.on({
                  // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
                  delegate: 'button',
              
                  tap: function() {
                      alert('Button tapped!');
                  }
              });
              
          • order : String (optional)

            The order of when the listener should be added into the listener queue. Possible values are before, current and after.

            Defaults to: 'current'

                  Returns the result of calling the overridden method

                Call the "parent" method of the current method. ...

                Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext.define).

                 Ext.define('My.Base', {
                     constructor: function (x) {
                         this.x = x;
                     },
                
                     statics: {
                         method: function (x) {
                             return x;
                         }
                     }
                 });
                
                 Ext.define('My.Derived', {
                     extend: 'My.Base',
                
                     constructor: function () {
                         this.callParent([21]);
                     }
                 });
                
                 var obj = new My.Derived();
                
                 alert(obj.x);  // alerts 21
                

                This can be used with an override as follows:

                 Ext.define('My.DerivedOverride', {
                     override: 'My.Derived',
                
                     constructor: function (x) {
                         this.callParent([x*2]); // calls original My.Derived constructor
                     }
                 });
                
                 var obj = new My.Derived();
                
                 alert(obj.x);  // now alerts 42
                

                This also works with static methods.

                 Ext.define('My.Derived2', {
                     extend: 'My.Base',
                
                     statics: {
                         method: function (x) {
                             return this.callParent([x*2]); // calls My.Base.method
                         }
                     }
                 });

                 alert(My.Derived2.method(10); // alerts 20
                

                Lastly, it also works with overridden static methods.

                 Ext.define('My.Derived2Override', {
                     override: 'My.Derived2',
                
                     statics: {
                         method: function (x) {
                             return this.callParent([x*2]); // calls My.Derived2.method
                         }
                     }
                 });
                
                 alert(My.Derived2.method(10); // now alerts 40

                                  The name of the event to fire.

                                • args : Array

                                  Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

                                  The first argument is the name of the event. Every other argument passed will be available when you listen for the event.

                                  Example

                                  Firstly, we set up a listener for our new event.

                                  this.on('myevent', function(arg1, arg2, arg3, arg4, options, e) {
                                      console.log(arg1); // true
                                      console.log(arg2); // 2
                                      console.log(arg3); // { test: 'foo' }
                                      console.log(arg4); // 14
                                      console.log(options); // the options added when adding the listener
                                      console.log(e); // the event object with information about the event
                                  });
                                  

                                  And then we can fire off the event.

                                  this.fireEvent('myevent', true, 2, { test: 'foo' }, 14);
                                  

                                  An event may be set to bubble up an Observable parent hierarchy by calling enableBubble.

                                                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.

                                                  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.

                                                  • order : String

                                                    The order of when the listener should be added into the listener queue.

                                                    If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

                                                    Available options are before, current and after. Defaults to current.

                                                  • buffer : Number

                                                    Causes the handler to be 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.

                                                  • element : String

                                                    Allows you to add a listener onto a element of this component using the elements reference.

                                                    Ext.create('Ext.Component', {
                                                        listeners: {
                                                            element: 'element',
                                                            tap: function() {
                                                                console.log('element tap!');
                                                            }
                                                        }
                                                    });
                                                    

                                                    All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

                                                  • delegate : String

                                                    Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

                                                    // Create a container with a two children; a button and a toolbar
                                                    var container = Ext.create('Ext.Container', {
                                                        items: [
                                                            {

                                                               title: 'My Toolbar'

                                                            }
                                                        ]
                                                    });

                                                        tap: function() {
                                                            alert('Button tapped!');

                                                              Important: Ajax server requests are asynchronous, and this call will return before the response has been received. Process any returned data in a callback function.

                                                                  • response : Object

                                                                • success : Function

                                                                    The XMLHttpRequest object containing the response data.

                                                                  • options : Object

                                                                    The parameter to the request call.

                                                                • scope : Object

                                                                  The scope in which to execute the callbacks: The "this" object for the callback function. If the url, or params options were specified as functions from which to draw values, then this also serves as the scope for those function calls. Defaults to the browser window.

                                                                • timeout : Number

                                                                  The timeout in milliseconds to be used for this request. Defaults to 30 seconds.

                                                                • form : HTMLElement/HTMLElement/String

                                                                  The <form> Element or the id of the <form> to pull parameters from.

                                                                • isUpload : Boolean

                                                                  Only meaningful when used with the form option.

                                                                  True if the form object is a file upload (will be set automatically if the form was configured with enctype "multipart/form-data").

                                                                  File uploads are not performed using normal "Ajax" techniques, that is they are not performed using XMLHttpRequests. Instead the form is submitted in the standard manner with the DOM <form> element temporarily modified to have its target set to refer to a dynamically generated, hidden <iframe> which is inserted into the document but removed after the return data has been gathered.

                                                                  The server response is parsed by the browser to create the document for the IFRAME. If the server is using JSON to send the return object, then the Content-Type header must be set to "text/html" in order to tell the browser to insert the text unchanged into the document body.

                                                                  The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a responseText property in order to conform to the requirements of event handlers and callbacks.

                                                                  Be aware that file upload packets are sent with the content type multipart/form and some server technologies (notably JEE) may require some custom processing in order to retrieve parameter names and parameter values from the packet content.

                                                                • headers : Object

                                                                • jsonData : Object/String

                                                              If events were suspended using the queueSuspended parameter, then all events fired during event suspension will be sent to any listeners now.
