Ext.form.action.Submit

The function to call when a failure packet was received, or when an error ocurred in the Ajax communication. The function is passed the following parameters:

• form : Ext.form.Basic
  The form that requested the action
• action : Ext.form.action.Action
  The Action class. If an Ajax error ocurred, the failure type will be in failureType. The result property of this object may be examined to perform custom postprocessing.

Available since: 1.1.0

The BasicForm instance that is invoking this Action. Required.

Available since: 4.0.0

Extra headers to be sent in the AJAX request for submit and load actions. See Ext.data.proxy.Ajax.headers.

Available since: 4.0.0

The HTTP method to use to access the requested URL. Defaults to the BasicForm's method, or 'POST' if not specified.

Available since: 1.1.0

Extra parameter values to pass. These are added to the Form's Ext.form.Basic.baseParams and passed to the specified URL along with the Form's input fields.

Parameters are encoded as standard HTTP parameters using Ext.Object.toQueryString.

Available since: 1.1.0

When set to true, causes the Form to be reset on Action success. If specified, this happens before the success callback is called and before the Form's actioncomplete event fires.

Available since: 2.3.0

The scope in which to call the configured success and failure callback functions (the this reference for the callback functions).

Available since: 2.3.0

If set to true, the emptyText value will be sent with the form when it is submitted. Defaults to true.

Defaults to: true

Available since: 3.4.0

The function to call when a valid success return packet is received. The function is passed the following parameters:

• form : Ext.form.Basic
  The form that requested the action
• action : Ext.form.action.Action
  The Action class. The result property of this object may be examined to perform custom postprocessing.

Available since: 1.1.0

The number of seconds to wait for a server response before failing with the failureType as CONNECT_FAILURE. If not specified, defaults to the configured timeout of the form.

Available since: 2.3.0

The URL that the Action is to invoke. Will default to the url configured on the form.

Available since: 1.1.0

The message to be displayed by a call to Ext.window.MessageBox.wait during the time the action is being processed.

Available since: 1.1.0

The title to be displayed by a call to Ext.window.MessageBox.wait during the time the action is being processed.

Available since: 1.1.0

The type of failure detected will be one of these: CLIENT_INVALID, SERVER_INVALID, CONNECT_FAILURE, or LOAD_FAILURE. Usage:

Get the reference to the current class from which this object was instantiated. Unlike statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics for a detailed comparison

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); / dependent on 'this'

        return this;
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        speciesName: 'Snow Leopard'         // My.SnowLeopard.speciesName = 'Snow Leopard'
    }
});

var cat = new My.Cat();                     // alerts 'Cat'
var snowLeopard = new My.SnowLeopard();     // alerts 'Snow Leopard'

var clone = snowLeopard.clone();
alert(Ext.getClassName(clone));             // alerts 'My.SnowLeopard'
