Ext.BaseExt.form.action.ActionExt.form.action.Load
A class which handles loading of data from a server into the Fields of an Ext.form.Basic.
+ + +Instances of this class are only created by a Form when +loading.
+ + +Response Packet Criteria
+ + +A response packet must contain: +
success property : Booleandata property : Objectdata property contains the values of Fields to load.
+The individual value object for each Field is passed to the Field's
+setValue method.JSON Packets
+By default, response packets are assumed to be JSON, so for the following form load call: +
var myFormPanel = new Ext.form.Panel({
+ title: 'Client and routing info',
+ items: [{
+ fieldLabel: 'Client',
+ name: 'clientName'
+ }, {
+ fieldLabel: 'Port of loading',
+ name: 'portOfLoading'
+ }, {
+ fieldLabel: 'Port of discharge',
+ name: 'portOfDischarge'
+ }]
+});
+myFormPanel.getForm().load({
+ url: '/getRoutingInfo.php',
+ params: {
+ consignmentRef: myConsignmentRef
+ },
+ failure: function(form, action) {
+ Ext.Msg.alert("Load failed", action.result.errorMessage);
+ }
+});
+{
+ success: true,
+ data: {
+ clientName: "Fred. Olsen Lines",
+ portOfLoading: "FXT",
+ portOfDischarge: "OSL"
+ }
+}{
+ success: false,
+ errorMessage: "Consignment reference not found"
+}Other data may be placed into the response for processing the Form's +callback or event handler methods. The object decoded from this JSON is available in the +result property.
+ +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:
Extra headers to be sent in the AJAX request for submit and load actions. See +Ext.data.Connection.headers.
+ +Extra headers to be sent in the AJAX request for submit and load actions. See +Ext.data.Connection.headers.
+ +The HTTP method to use to access the requested URL. Defaults to the +BasicForm's method, or 'POST' if not specified.
+The HTTP method to use to access the requested URL. Defaults to the +BasicForm's method, or 'POST' if not specified.
+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.
+ +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.
+The scope in which to call the configured success and failure +callback functions (the this reference for the callback functions).
+If set to true, the emptyText value will be sent with the form +when it is submitted. Defaults to true.
+If set to true, the emptyText value will be sent with the form +when it is submitted. Defaults to true.
+The function to call when a valid success return packet is received. +The function is passed the following parameters:
The number of seconds to wait for a server response before +failing with the failureType as Ext.form.action.Action.CONNECT_FAILURE. If not specified, +defaults to the configured timeout of the +form.
+The message to be displayed by a call to Ext.window.MessageBox.wait +during the time the action is being processed.
+The message to be displayed by a call to Ext.window.MessageBox.wait +during the time the action is being processed.
+The title to be displayed by a call to Ext.window.MessageBox.wait +during the time the action is being processed.
+The title to be displayed by a call to Ext.window.MessageBox.wait +during the time the action is being processed.
+Failure type returned when client side validation of the Form fails +thus aborting a submit action. Client side validation is performed unless +Ext.form.action.Submit.clientValidation is explicitly set to false.
+Failure type returned when a communication error happens when attempting +to send a request to the remote server. The response may be examined to +provide further information.
+Failure type returned when the response's success +property is set to false, or no field values are returned in the response's +data property.

+The type of failure detected will be one of these: Ext.form.action.Action.CLIENT_INVALID, +Ext.form.action.Action.SERVER_INVALID, Ext.form.action.Action.CONNECT_FAILURE, or +Ext.form.action.Action.LOAD_FAILURE. Usage:
+ +var fp = new Ext.form.Panel({
+...

+ text: 'Save',
+ formBind: true,
+ handler: function(){
+ if(fp.getForm().isValid()){
+ fp.getForm().submit({
