Re: [jQuery] OT: technique to pass values to JS/JQuery through HTML

[Paul Bakaus]

Hi there,another interesting feature I use very often is to extend the XHTML namespace and just use custom attributes like isDisabled, isEditable and such stuff.At any rate, your browser will ignore these attributes and you will have access to them via getAttribute, if you want a validating xhtml file, you should also add a custom dtd file. Check this out:

[EMAIL PROTECTED]:Hi Klaus,thanks for your answer and your hint to w3! So it seems to be a common
technique. I was wondering if I am the only one doing this, but it'sgood to know that I have accomplices out there ;-)Cheers, ArashKlaus Hartl schrieb:Arash, you could as an alternative use the class attribute for that, but

Arash, you could as an alternative use the class attribute for that, but 
theres no need to feel false about the id as well. From the HTML Spec:


The id attribute has several roles in HTML:

 * As a style sheet selector.
 * As a target anchor for hypertext links.
 * As a means to reference a particular element from a script.
 * As the name of a declared OBJECT element.
 * For general purpose processing by user agents (e.g. for 
identifying fields when extracting data from HTML pages into a database, 
translating HTML documents into other formats, etc.).

The class attribute, on the other hand, assigns one or more class names 
to an element; the element may be said to belong to these classes. A 
class name may be shared by several element instances. The class 
attribute has several roles in HTML:

information to a set of elements).
