Gets an attribute for an element from the attributes collection.
Syntax
oItem = attributes.item(vIndex)
Parameters
| vIndex |
Required.
Integer or String that specifies the attribute. If this parameter is an integer, it is the zero-based index of the attribute to be retrieved from
the attributes collection. If this parameter is a string, the attribute whose name matches the string is retrieved. |
Return Value
Returns an attribute if successful, otherwise null.
Remarks
This method returns an error if the attribute is not found. When the item method gets an attribute by name, vIndex
must match the case of the attribute.
Examples
This example uses the item method to get the name and value of each attribute for an element, and to determine whether the attribute has been specified.
