Summary
Returns a node from a NodeList
by index. This method doesn't throw exceptions as long as you provide arguments; a value of null
is returned if the index is out of range and a TypeError
is thrown if no argument is provided.
Syntax
nodeItem = nodeList.item(index)
nodeList
is aNodeList
. This is usually obtained from another DOM property or method, such as childNodes.index
is the index of the node to be fetched. The index is zero-based.nodeItem
is theindex
th node in thenodeList
returned by theitem
method.
JavaScript has a special simpler syntax for obtaining an item from a NodeList by index:
nodeItem = nodeList[index]
Example
var tables = document.getElementsByTagName("table"); var firstTable = tables.item(1); // or simply tables[1] - returns the second table in the DOM
