Allow setting of tabindex in presentation layer

[mike@…]

I needed this for a project that I was working on, and I thought I would put the function here. I am a very new Django user and haven't so much as looked at its source code yet, but if I can get to it after my current project is finished, I'll be happy to contribute this as a proper patch if desired.

Essentially, this is a filter for use on form fields, links, etc. in order to add a tabindex attribute to it. In order to remain light, it doesn't call up an HTML parser, and so it naïvely appends tabindex="X" to the end of the list of attributes. It handles both /> and normal > tag closure, so that it works for both types of tags. If it cannot find an end-of-tag, it returns the input unaltered. Furthermore, if the tabindex parameter is passed in as a string it will attempt conversion to an integer; if that fails, it will also return the input as-is.

A tabindex filter

I think this is a good candidate for ​http://djangosnippets.org/

However, it looks too specialized for Django itself, so I vote -1 for adding it to Django.

Let's wait for a core developer's opinion — I'm not allowed to close a ticket as "wontfix".

I agree with aaugustin - this isn't an appropriate addition to Django. Further, this ought to be fixed by the widget rendering improvements hopefully coming in 1.4, so it'll be redundant very soon.

Thanks for the suggestion!
