Retrieves a collection of objects that have the specified HTML tag name.
Syntax
collElements = object.tags(sTag)
Parameters
| sTag |
Required.
Variant of type String that specifies an HTML tag. It can be any one of the objects exposed by the DHTML Object Model. |
Return Value
Returns
a collection of element objects if successful, or null otherwise.
Remarks
Successful execution includes the case where no elements having the given name are found.
In this case, a collection containing zero elements is returned.
The length property of the collection contains the number of elements in the collection.
NULL may be returned in cases where the collection cannot be constructed, such as inability to allocate memory for even a zero-length collection.
Example
This example uses the
tags method to retrieve a collection of all
p elements in the document, and all
body elements in the document.
It displays some of the properties of the collections that are returned.
It then displays selected elements of the collection.
There are no
p elements in the document, and there is one
body element in the document.
So, this example illustrates both the cases where the collection is empty and where the collection is populated.
