XML DOM isId Property

Attr Object Reference Complete Attr Object Reference

Definition and Usage

The isId property returns true if an attribute is known to be of type ID (e.g. contains an identifier for its owner element), otherwise it returns false.

Syntax

Example

The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and returns whether the category attribute is an ID attribute of the <book> element:

Example

xmlDoc=loadXMLDoc("books.xml");

x=xmlDoc.getElementsByTagName('book');

for(i=0;i<x.length;i++)
{
document.write(x.item(i).attributes[0].isId);
document.write("<br />");
}

The output of the code above will be:
