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.
-Add / override static properties of this class.
- -Ext.define('My.cool.Class', {
- ...
-});
-
-My.cool.Class.addStatics({
- someProperty: 'someValue', // My.cool.Class.someProperty = 'someValue'
- method1: function() { ... }, // My.cool.Class.method1 = function() { ... };
- method2: function() { ... } // My.cool.Class.method2 = function() { ... };
-});
-Borrow another class' members to the prototype of this class.
- -Ext.define('Bank', {
- -money: '$$$',
-printMoney: function() {
- alert('$$$$$$$');
-}
-});
- -Ext.define('Thief', {
- -...
-});
- -Thief.borrow(Bank, ['money', 'printMoney']);
- -var steve = new Thief();
- -alert(steve.money); // alerts '$$$' -steve.printMoney(); // alerts '$$$$$$$'
-Create a new instance of this Class. -Ext.define('My.cool.Class', {
- -...
-});
- -My.cool.Class.create({
- -someConfig: true
-});
-Create aliases for existing prototype methods. Example:
- -Ext.define('My.cool.Class', {
- method1: function() { ... },
- method2: function() { ... }
-});
-
-var test = new My.cool.Class();
-
-My.cool.Class.createAlias({
- method3: 'method1',
- method4: 'method2'
-});
-
-test.method3(); // test.method1()
-
-My.cool.Class.createAlias('method5', 'method3');
-
-test.method5(); // test.method3() -> test.method1()
-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({
-...
-buttons: [{
- text: 'Save',
- formBind: true,
- handler: function(){
- if(fp.getForm().isValid()){
- fp.getForm().submit({
- url: 'form-submit.php',
- waitMsg: 'Submitting your data...',
- success: function(form, action){
- // server responded with success = true
- var result = action.result;
- },
- failure: function(form, action){
- if (action.failureType === Ext.form.action.Action.CONNECT_FAILURE) {
- Ext.Msg.alert('Error',
- 'Status:'+action.response.status+': '+
- action.response.statusText);
- }
- if (action.failureType === Ext.form.action.Action.SERVER_INVALID){
- // server responded with success = false
- Ext.Msg.alert('Invalid', action.result.errormsg);
- }
- }
- });
- }
- }
-},{
- text: 'Reset',
- handler: function(){
- fp.getForm().reset();
- }
-}]
-Add methods / properties to the prototype of this class.

- constructor: function() {
- ...
- }
-});
-
- My.awesome.Cat.implement({
- meow: function() {
- alert('Meowww...');
- }
- });
-
- var kitty = new My.awesome.Cat;
- kitty.meow();
-Override prototype members of this class. Overridden methods can be invoked via -Ext.Base.callOverridden
- -Ext.define('My.Cat', {
- constructor: function() {
- alert("I'm a cat!");
-
