[Javascript] Loading Problem

Wed Sep 15 06:45:46 CDT 2004

Well, the sScriptTag was just me creating a variable to act as a reference
to the named script tag.  Nothing strange going on there.

The script tag attributes "for" and "event", however, if you don't already
know about them, can be very useful.  I use them often.  You can use them to
bind object events to script tags: for instance, in the example I provided
earlier the code would run when the window loads.

You could, for example do this ...

<img src="a_pretty_picture.jpg" id="myPic">
<script language="javascript" for="myPic" event="onmouseover">
    alert ('The mouse went over the picture');
</script>

... if you wanted.

There's many different ways to do exactly the same thing (I'll provide
examples if you want), it just so happens that this method is particularly
useful for me, given the mechanisms that build up pages in my intranet
system.

Should be noted that (according to O'Reilly) Netscape doesn't support these
features.
