Introduction
cssQuery() is a powerful cross-browser JavaScript function that enables querying of a DOM document using CSS selectors. All CSS1 and CSS2 selectors are allowed plus quite a few CSS3 selectors.
Usage
Syntax
elements = cssQuery(selector [, from]);where selector (required) is a valid CSS selector and from (optional) is a document, element or array of elements which is filtered by selector.
The function returns a JavaScript array of elements. If there is no match, an empty array is returned.
Some examples:
// find all paragraphs that are direct descendants// of the document bodyvar tags = cssQuery("body > p");// find all elements with the "href" attributevar tags = cssQuery("[href]");// find all anchor elements with "href" equal to "#"var tags = cssQuery("a[href='#']");// find all images contained by the above anchorsvar images = cssQuery("img", tags);// find all listsvar tags = cssQuery("dl,ol,ul");// query an external xml documentvar tags = cssQuery("my|:root>my|link", myXMLDoc);// just plain complicatedvar complex = "p>a:first-child+input[type=text]~span";var tags = cssQuery(complex);Allowed Selectors
