Notes: If it is not obvious, the length property can also report the number of elements in the wrapper set—stated another way, how many elements were selected by the expression passed to the jQuery function. Creating custom filters for selecting elements The capabilities of the jQuery selector engine can be extended by creating your own custom filters. In theory, all you are doing here is building upon the custom selectors that are already part of jQuery. For example, say we would like to select all elements on a Web page that are absolutely positioned. Since jQuery does not already have a custom :positionAbsolute filter, we can create our own. Sample: sample26.html
