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
<SCRIPT LANGUAGE="VBScript" ID="HelloScript">
would return "VBScript" as they both reference the same script.
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
item method retrieves single items, or sub-collections from the scripts collection. It accepts the following arguments:
index is a number, then the method returns a reference to the
<SCRIPT> element object at that position in the scripts collections index.
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
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.
