Ext.form.action.Load

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.

Failure type returned when server side processing fails and the result's success property is set to false.

In the case of a form submission, field-specific error messages may be returned in the result's errors 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.

Ext.define('My.awesome.Cat', {
    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!");

        return this;
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        var instance = this.callOverridden();

        alert("Meeeeoooowwww");

        return instance;
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"
