- Parameters:
-
- Element
- The Element to test.
- node.mask optional
-
A bitwise mask used to filter the results. See the Node Masking page for more information.
If omitted, a mask of 1 (matching for nodeType 1) is used.
- tagName optional
- A tagName to match. When used instead of a node.mask only elements of node type 1 with a matching tagName will be counted.
- Returns:
- Boolean true or false
- Properties:
-
The following "constants" exist to aid in creating masks.
_.Node.mask.ELEMENT = 0x0001; // nodeType 1 _.Node.mask.TEXT = 0x0004; // nodeType 3 _.Node.mask.PROCESSING = 0x0040; // nodeType 7 _.Node.mask.COMMENT = 0x0080; // nodeType 8 _.Node.mask.DOCUMENT = 0x0100; // nodeType 9 _.Node.mask.DOCTYPE = 0x0200; // nodetype 10 _.Node.mask.FRAGMENT = 0x0400; // nodeType 11
Example
HTML
<div id="test"></div>
JavaScript
var test = document.getElementById('test');
console.log('#test is a Element node: ', _.Node.mask(test));
console.log('#test is a Element node (direct): ', _.Node.mask(test, _.Node.mask.ELEMENT));
console.log('#test is a Comment node: ', _.Node.mask(test, _.Node.mask.COMMENT));
console.log('#test is a DIV tag: ', _.Node.mask(test, 'div'));
console.log('#test is a UL tag: ', _.Node.mask(test, 'ul'));
Output
#test is a Element node: true #test is a Element node (direct): true #test is a Comment node: false #test is a DIV tag: true #test is a UL tag: false
