Method _.Node.countAll


Counts the number of elements inside the target element, using a nodeType or tagName mask.

Calling Convention:
_.Node.countAll(Element[, nodeMask || tagName])
The target Element to count the nodes inside of.
nodeMask 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 nodeMask only elements of node type 1 with a matching tagName will be counted.
A integer count of the number of matching DOM elements inside Element

Example #1


<div id="test">
		<h2>Section 1</h2>
		<p>This is a <strong>test</strong></p>
		<p>This is another paragraph</p>


Console.log(_.Node.countAll(_d.getElementById('test'))); // 5
Console.log(_.Node.countAll(_d.getElementById('test'), 'p')); // 2

A result of 5 is reported by the first log entry because by default only nodeType 1 is matched, and there are four tags TOTAL inside div#test. A result of 2 is reported by the second logging since we're only checking for paragraphs.
