Note : The Scripts collection is Internet Explorer 4.0 specific. The <SCRIPT>
element supports the standard Internet Explorer 4.0 attributes of CLASS, ID, TITLE, as well as its own SRC, LANGUAGE, FOR and EVENT attributes (and Dynamic HTML properties of the same names and other standard Dynamic HTML properties and methods.
The Scripts collection is an ordered, indexed (by order in the source) array, containing a reference to every <SCRIPT>
element in a document.
Script Objects would normally be retrieved by their index in the All collection (for example, above document.scripts(3)
contains a reference to the third <SCRIPT>
element in the document), but a string value can be used, as long as that string is a valid identifier (ID
attribute value) for a <SCRIPT>
element in the document.
E.g., consider the following to be the second <SCRIPT>
element in the document
Note: the use of the language tag has been depreciated. Use type="text/javascript" instead. |
<SCRIPT LANGUAGE="VBScript" ID="HelloScript">
msgbox "Hello"
</SCRIPT>
both:
document.scripts(1).language
and
document.scripts("HelloScript").language
would return "VBScript" as they both reference the same script.
length
The length
property returns the number of <SCRIPT>
elements in the collection. Note that the length
count starts at 1, not 0 as the scripts collection index does. Therefore, the length
property may return a value of 5, but to access the 3rd element, you'd need to use document.scripts(2).property
item
The item
method retrieves single items, or sub-collections from the scripts collection. It accepts the following arguments:
scripts.item(index, sub-index)
If index
is a number, then the method returns a reference to the <SCRIPT>
element object at that position in the scripts collections index.
If the index
property is a string value, then the item
method returns a sub-collection, containing a reference to every element in the document that has its ID
or NAME
attribute set to the string contained in the index
argument (Note that if you are using ID
attributes only to uniquely identify scripts, then the sub-collection will only contain the one item). To retrieve certain element objects from this sub-collection, the sub-index
argument must be used.
