Class Ext

Copies all the properties of config to obj.

Copies all the properties of config to obj if they don't already exist.

Shorthand for Ext.util.JSON.decode

Iterates an array calling the passed function with each item, stopping if your function returns false. If the passed array is not really an array, your function is called once with it. The supplied function is called with (Object item, Number index, Array allItems).

Shorthand for Ext.util.JSON.encode

Extends one class with another class and optionally overrides members with the passed literal. This class also adds the function "override()" to the class that can be used to override members on an instance.

This function also supports a 2-argument call in which the subclass's constructor is not passed as an argument. In this form, the parameters are as follows:

For example, to create a subclass of the Ext GridPanel:

MyGridPanel = Ext.extend(Ext.grid.GridPanel, {
    constructor: function(config) {
        // Your preprocessing here
        MyGridPanel.superclass.constructor.apply(this, arguments);
        // Your postprocessing here
    },

    yourMethod: function() {
        // etc.
    }
});

Gets the globally shared flyweight Element, with the passed node as the active element. Do not store a reference to this element - the dom node can be overwritten by other code. Shorthand of Ext.Element.fly

Use this to make one-time references to DOM elements which are not going to be accessed again either by application code, or by Ext's classes. If accessing an element which will be processed regularly, then Ext.get will be more appropriate to take advantage of the caching provided by the Ext.Element class.

Retrieves Ext.Element objects.

This method does not retrieve Components. This method retrieves Ext.Element objects which encapsulate DOM elements. To retrieve a Component by its ID, use Ext.ComponentMgr.get.

Uses simple caching to consistently return the same object. Automatically fixes if an object was recreated with the same id via AJAX or DOM.

Shorthand of Ext.Element.get

Returns the current document body as an Ext.Element.

Return the dom node for the passed string (id), dom node, or Ext.Element. Note: the dom node to be found actually needs to exist (be rendered, etc) when this method is called to be successful.

Generates unique ids. If the element already has an id, it is unchanged

Returns true if the passed object is a JavaScript array, otherwise false.

Returns true if the passed value is empty.

The value is deemed to be empty if it is

Returns true if the passed object is a JavaScript Function, otherwise false.

Returns true if the passed object is a JavaScript Object, otherwise false.

Returns true if the passed object is a JavaScript 'primitive', a string, number or boolean.

Creates namespaces to be used for scoping variables and classes so that they are not global. Specifying the last node of a namespace implicitly creates all other nodes. Usage:

Ext.namespace('Company', 'Company.data');
Ext.namespace('Company.data'); // equivalent and preferable to above syntax
Company.Widget = function() { ... }
Company.data.CustomStore = function(config) { ... }

Fires when the document is ready (before onload and before images are loaded). Shorthand of Ext.EventManager.onDocumentReady.

Adds a list of functions to the prototype of an existing class, overwriting any existing methods with the same name. Usage:

Ext.override(MyClass, {
    newMethod1: function(){
        // etc.
    },
    newMethod2: function(foo){
        // etc.
    }
});

Selects an array of DOM nodes by CSS/XPath selector. Shorthand of Ext.DomQuery.select

Removes a DOM node from the document. The body node will be ignored if passed in.

Converts any iterable (numeric indices and a length property) into a true array Don't use this on strings. IE doesn't support "abc"[0] which this implementation depends on. For strings, use this instead: "abc".match(/./g) => [a,b,c];

Takes an encoded URL and and converts it to an object. Example:

Ext.urlDecode("foo=1&bar=2"); // returns {foo: "1", bar: "2"}
Ext.urlDecode("foo=1&bar=2&bar=3&bar=4", false); // returns {foo: "1", bar: ["2", "3", "4"]}

Takes an object and converts it to an encoded URL. e.g. Ext.urlEncode({foo: 1, bar: 2}); would return "foo=1&bar=2". Optionally, property values can be arrays, instead of keys and the resulting string that's returned will contain a name/value pair for each array value.
