- </span> * @class Ext.form.action.DirectLoad
- * @extends Ext.form.action.Load
- * <p>Provides {@link Ext.direct.Manager} support for loading form data.</p>
- * <p>This example illustrates usage of Ext.direct.Direct to <b>load</b> a form through Ext.Direct.</p>
- * <pre><code>
- var myFormPanel = new Ext.form.Panel({
- // configs for FormPanel
- title: 'Basic Information',
- renderTo: document.body,
- width: 300, height: 160,
- padding: 10,
- // configs apply to child items
- defaults: {anchor: '100%'},
- defaultType: 'textfield',
- items: [{
- fieldLabel: 'Name',
- name: 'name'
- },{
- fieldLabel: 'Email',
- name: 'email'
- },{
- fieldLabel: 'Company',
- name: 'company'
- }],
- // configs for BasicForm
- api: {
- // The server-side method to call for load() requests
- load: Profile.getBasicInfo,
- // The server-side must mark the submit handler as a 'formHandler'
- submit: Profile.updateBasicInfo
- },
- // specify the order for the passed params
- paramOrder: ['uid', 'foo']
- });
- // load the form
- myFormPanel.getForm().load({
- // pass 2 arguments to server side getBasicInfo method (len=2)
- params: {
- foo: 'bar',
- uid: 34
- }
- });
- * </code></pre>
- * The data packet sent to the server will resemble something like:
- * <pre><code>
- [
- {
- "action":"Profile","method":"getBasicInfo","type":"rpc","tid":2,
- "data":[34,"bar"] // note the order of the params
- }
- ]
- * </code></pre>
- * The form will process a data packet returned by the server that is similar
- * to the following format:
- * <pre><code>
- [
- {
- "action":"Profile","method":"getBasicInfo","type":"rpc","tid":2,
- "result":{
- "success":true,
- "data":{
- "name":"Fred Flintstone",
- "company":"Slate Rock and Gravel",
- "email":"fred.flintstone@slaterg.com"
- }
- }
- }
- ]
- * </code></pre>
