/**
|
||||
* @class Ext.ComponentQuery
|
||||
* @extends Object
|
||||
* @singleton
|
||||
*
|
||||
* Provides searching of Components within {@link Ext.ComponentManager} (globally) or a specific
|
||||
* {@link Ext.Container} on the document with a similar syntax to a CSS selector.
|
||||
*
|
||||
* Components can be retrieved by using their {@link Ext.Component xtype} with an optional '.' prefix
|
||||
*
|
||||
* - `component` or `.component`
|
||||
* - `gridpanel` or `.gridpanel`
|
||||
*
|
||||
* An itemId or id must be prefixed with a #
|
||||
*
|
||||
* - `#myContainer`
|
||||
*
|
||||
* Attributes must be wrapped in brackets
|
||||
*
|
||||
* - `component[autoScroll]`
|
||||
* - `panel[title="Test"]`
|
||||
*
|
||||
* Member expressions from candidate Components may be tested. If the expression returns a *truthy* value,
|
||||
* the candidate Component will be included in the query:
|
||||
*
|
||||
* var disabledFields = myFormPanel.query("{isDisabled()}");
|
||||
*
|
||||
* Pseudo classes may be used to filter results in the same way as in {@link Ext.DomQuery DomQuery}:
|
||||
*
|
||||
* // Function receives array and returns a filtered array.
|
||||
* Ext.ComponentQuery.pseudos.invalid = function(items) {
|
||||
* var i = 0, l = items.length, c, result = [];
|
||||
* for (; i < l; i++) {
|
||||
* if (!(c = items[i]).isValid()) {
|
||||
* result.push(c);
|
||||
* }
|
||||
* }
|
||||
* return result;
|
||||
* };
|
||||
*
|
||||
* var invalidFields = myFormPanel.query('field:invalid');
|
||||
* if (invalidFields.length) {
|
||||
* invalidFields[0].getEl().scrollIntoView(myFormPanel.body);
|
||||
* for (var i = 0, l = invalidFields.length; i < l; i++) {
|
||||
* invalidFields[i].getEl().frame("red");
|
||||
* }
|
||||
* }
|
||||
*
|
||||
* Default pseudos include:
|
||||
*
|
||||
* - not
|
||||
*
|
||||
* Queries return an array of components.
|
||||
* Here are some example queries.
|
||||
*
|
||||
* // retrieve all Ext.Panels in the document by xtype
|
||||
* var panelsArray = Ext.ComponentQuery.query('panel');
|
||||
*
|
||||
* // retrieve all Ext.Panels within the container with an id myCt
|
||||
* var panelsWithinmyCt = Ext.ComponentQuery.query('#myCt panel');
|
||||
*
|
||||
* // retrieve all direct children which are Ext.Panels within myCt
|
||||
* var directChildPanel = Ext.ComponentQuery.query('#myCt > panel');
|
||||
*
|
||||
* // retrieve all grids and trees
|
||||
* var gridsAndTrees = Ext.ComponentQuery.query('gridpanel, treepanel');
|
||||
*
|
||||
* For easy access to queries based from a particular Container see the {@link Ext.Container#query},
|
||||
* {@link Ext.Container#down} and {@link Ext.Container#child} methods. Also see
|
||||
* {@link Ext.Component#up}.
