Action Action.Load Action.DirectLoad
Package: | Ext.form |
Defined In: | Action.js |
Class: | Action.DirectLoad |
Extends: | Action.Load |
Provides Ext.direct support for loading form data.
This example illustrates usage of Ext.Direct to load a form through Ext.Direct.
var myFormPanel = new Ext.form.FormPanel({
// 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
}
});
The data packet sent to the server will resemble something like:
[
{
"action":"Profile","method":"getBasicInfo","type":"rpc","tid":2,
"data":[34,"bar"] // note the order of the params
}
]
The form will process a data packet returned by the server that is similar
to the following format:
[
{
"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"
}
}
}
]
