Note : Both Netscape and Internet Explorer support the Applets collection (Netscape call it an array). For properties, methods and events that are supported by <APPLET>
elements, see the <APPLET>
topic.
The Applets collection is an ordered, indexed array, containing a reference to every <APPLET>
element in a document.
Applet Objects would normally be retrieved by their index in the Applets collection. I.e.:
document.applets(1).code
returns the CODE
attribute of the second applet in the document.
A string value can be used however, as long as that string is a valid identifier (ID
attribute value) for an <APPLET>
element in the document.
E.g.
document.applets('MyCoolApplet').code
would return the CODE
attribute of the applet whose NAME
(or ID
) property is 'MyCoolApplet'.
length
The length
property returns the number of applet objects in the collection. Note that the length
count starts at 1, not 0 as the applets collection index does. Therefore, the length
property may return a value of 5, but to access the 3rd anchor, you'd need to use document.applets(2).property
item
The item
method retrieves single items, or sub-collections from the applets collection. It accepts the following arguments:
applets.item(index, sub-index)
If index
is a number, then the method returns a reference to the applet at that position in the applets collections index. I.e.
strTag=document.applets.item(2).code
would make strTag
be the value of the CODE
attribute of the documents third applet. As you can see, this is effectively the long-hand version of using document.applets(2).property
.
If the index
property is a string value, then the item
method returns a sub-collection, containing a reference to every anchor in the document that has its NAME
or ID
attribute set to the string contained in the index
argument. To retrieve certain element objects from this sub-collection, the sub-index
argument must be used.
