|
</span> * @class Ext.dom.Query
|
* @alternateClassName Ext.DomQuery
|
* @alternateClassName Ext.core.DomQuery
|
* @singleton
|
*
|
* Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes
|
* and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
|
*
|
* DomQuery supports most of the [CSS3 selectors spec][1], along with some custom selectors and basic XPath.
|
*
|
* All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example
|
* `div.foo:nth-child(odd)[@foo=bar].bar:first` would be a perfectly valid selector. Node filters are processed
|
* in the order in which they appear, which allows you to optimize your queries for your document structure.
|
*
|
* ## Element Selectors:
|
*
|
* - **`*`** any element
|
* - **`E`** an element with the tag E
|
* - **`E F`** All descendent elements of E that have the tag F
|
* - **`E > F`** or **E/F** all direct children elements of E that have the tag F
|
* - **`E + F`** all elements with the tag F that are immediately preceded by an element with the tag E
|
* - **`E ~ F`** all elements with the tag F that are preceded by a sibling element with the tag E
|
*
|
* ## Attribute Selectors:
|
*
|
* The use of `@` and quotes are optional. For example, `div[@foo='bar']` is also a valid attribute selector.
|
*
|
* - **`E[foo]`** has an attribute "foo"
|
* - **`E[foo=bar]`** has an attribute "foo" that equals "bar"
|
* - **`E[foo^=bar]`** has an attribute "foo" that starts with "bar"
|
* - **`E[foo$=bar]`** has an attribute "foo" that ends with "bar"
|
* - **`E[foo*=bar]`** has an attribute "foo" that contains the substring "bar"
|
* - **`E[foo%=2]`** has an attribute "foo" that is evenly divisible by 2
|
* - **`E[foo!=bar]`** attribute "foo" does not equal "bar"
|
*
|
* ## Pseudo Classes:
|
*
|
* - **`E:first-child`** E is the first child of its parent
|
* - **`E:last-child`** E is the last child of its parent
|
* - **`E:nth-child(_n_)`** E is the _n_th child of its parent (1 based as per the spec)
|
* - **`E:nth-child(odd)`** E is an odd child of its parent
|
* - **`E:nth-child(even)`** E is an even child of its parent
|
* - **`E:only-child`** E is the only child of its parent
|
* - **`E:checked`** E is an element that is has a checked attribute that is true (e.g. a radio or checkbox)
|
* - **`E:first`** the first E in the resultset
|
* - **`E:last`** the last E in the resultset
|
* - **`E:nth(_n_)`** the _n_th E in the resultset (1 based)
|
* - **`E:odd`** shortcut for :nth-child(odd)
|
* - **`E:even`** shortcut for :nth-child(even)
|
* - **`E:contains(foo)`** E's innerHTML contains the substring "foo"
|
* - **`E:nodeValue(foo)`** E contains a textNode with a nodeValue that equals "foo"
|
* - **`E:not(S)`** an E element that does not match simple selector S
|
* - **`E:has(S)`** an E element that has a descendent that matches simple selector S
|
* - **`E:next(S)`** an E element whose next sibling matches simple selector S
|
* - **`E:prev(S)`** an E element whose previous sibling matches simple selector S
|
* - **`E:any(S1|S2|S2)`** an E element which matches any of the simple selectors S1, S2 or S3
|
* - **`E:visible(true)`** an E element which is deeply visible according to {@link Ext.dom.Element#isVisible}
|
*
|
* ## CSS Value Selectors:
|
*
|
* - **`E{display=none}`** css value "display" that equals "none"
|
* - **`E{display^=none}`** css value "display" that starts with "none"
|
* - **`E{display$=none}`** css value "display" that ends with "none"
|
* - **`E{display*=none}`** css value "display" that contains the substring "none"
|
* - **`E{display%=2}`** css value "display" that is evenly divisible by 2
|
* - **`E{display!=none}`** css value "display" that does not equal "none"
|
*
|
* ## XML Namespaces:
|
* - **`ns|E`** an element with tag E and namespace prefix ns
|
