Question

If I have an element like:

<a href="javascript:void(0);" id="updates_toggle">0 Updates</a>

Can I remove only the letters dynamically? And it is possible to wrap it in a SPAN?

I need it to be like this:

<a href="javascript:void(0);" id="updates_toggle"><span>0</span></a>

And I would like to not use jQuery, and use only Mootools or pure JS.

Thanks.

Get what’s in the element, replace away anything that isn’t digits, and put it back wrapped in a span:

var el = document.getElementById('updates_toggle');
el.innerHTML = '<span>' + el.innerHTML.replace(/\D/g, '') + '</span>';
