XML DOM isId Property


Attr Object Reference Attr Object

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

attrObject.isId


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("
");
}

The output of the code above will be:

false
