class="init" meaning inside declaration

Question

I've come across the following code for Datatables jquery plugin:

<script type="text/javascript" language="javascript" class="init">
        $(document).ready(function() {
            $('#example').dataTable();
        } );
</script>

What is the purpose of class="init" ??

Maybe it's for selecting certain scripts? @elclanrs Scripts wouldn't show anyways. — Scimonster, Sep 22 '14 at 08:05

tag of script cannot have class attribute http://www.w3schools.com/tags/tag_script.asp — easywaru, Sep 22 '14 at 08:08
Please note that w3schools is not an authority. It would be better to link to the actual spec. — rnevius, Sep 22 '14 at 08:09

It just invalidates your code.

class is not allowed on script, in HTML4 and XHTML.

Although it IS valid in HTML5, as the <script> tag supports global attributes (which includes class).

Check out the specification.

You can select that script tag just like any other tag in DOM. Purpose? From CSS "visualization" where code block is, to JS/jQuery dynamic code generation.

Somewhere it could be used is dynamically selecting one from many script snippets to use elsewhere. Like javascript templating language

<script class="say_hello english" type="text/x-handlebars-template">
    <p>Hello {{name}}</p>
</script>
<script class="say_hello german" type="text/x-handlebars-template">
   <p>Hallo {{name}}</p>
</script>

...

var say_hello_template = Handlebars.compile($('script.say_hello.' + language).html()); 
$('#header').append(say_hello_template(user));

I hope it helps

In the javascript file, which you have included using tag like <script type="text/javascript" language="javascript" class="init" src="../../js/jFile.js"></script> may contains the coding which refers to the class init. This type of class seems like a CSS coding, but it is a reference to javascript.

Open the javascript in a text editor and search for the term "init". The coding may also be defined as mentioned in the article Is there a benefit to putting a class on a script tag?
