Is there a possibility to get the information of the <script>-Tag
inside a Prototype-Class?
E.g.:
<script id="myId">
var Animal = Class.create({
initialize: function(name, sound) {
this.name = name;
this.sound = sound;
}
});
</script>
Can I get the id-information ("myId") of <script> inside the
Animal-
class?
Thanks for comments!

for example
<script id="myScriptTag" language="text/javascript"
src="path/to/src">
...
...
...
//thosands lines of code after
</script>
you can get the language information
$(''myScriptTag'').readAttribute(''language'');

oh! sorry i didn''t read "I DO NOT HAVE the id"
well then a solution could be getting all the script tags in the document
$$(''script'').each(function(e){
var id = $(e).identify();
alert((e).readAttribute(''language''));
});

I figured out, that I described my Problem in a wrong way. This is my
scenario:
HTML:
<script id="myId">
new Animal(''Dog'',''Wuff'');
</script>
Thats somewhere in my JavaScript:
var Animal = Class.create({
initialize: function(name, sound) {
this.name = name;
this.sound = sound;
// HERE I WANT TO GET THE ID OF THE SCRIPT, THAT CALLED THIS CLASS
}
});
Consider the comment ... Thanks for information!

The assumption is that the code must be in the last one. However, that method is very unreliable. As far as I know, there are no others. If you control the page, surely you know which script element your code is in? Anyhow, what do you expect to achieve by removing the script element? -- Rob --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

A <script> tag is not a visual HTML tag, it doesn''t have a
position in
the DOM (in the traditional sense) so you shouldn''t use if for DOM
manipulation. All your javascript within the <script> tag is
executing in the global scope, the same as if you had the <script> tag
in the head. If you need to add something to the page, select a
visual HTML tag(A,BR,H1,DIV,SPAN,OL,LI,etc.) and position your dynamic
element based on that.
Example:
<html>
<head>
<script type="text/javascript"
src="prototype.js"></script>
<script type="text/javascript">
Event.observe(window, ''load'', function(){
var newEl = new Element("BR");
$(''someElement'').insert(newEl);
});
</script>
</head>
<div id="someElement">
<!-- Where I want to position my element -->
</div>
</html>
Also, its considered poor form to put <script> tags within the
<body>
of your HTML.
I hope I interpreted you question correctly. Good Luck.

How about creating a variable and change it''s value each time one of your dynamically generated scripts are created. <script> var me = ''1''; ...do your stuff here... </script> ...more code or what not... <script> var me = ''2''; ... do your stuff here... </script> Greg On Feb 27, 2008, at 8:01 AM, ohneworte wrote:> >> ID is not a valid attribute for script elements in HTML 4. > I know, but it doesn´t matter in this case.

Good proposal, but I want to provide my classes/functions/etc. to other developers, why a workaround like this should be avoided. Hmm, ...
