One of the ways of adding data to your markup that can be quite useful is being able to grab database information such as ids from classes. Here is a generic function for doing this (I can’t find a way to get pre blocks working on here, which makes this look messy…):

function getNumberFromClassName(el, prefix) { var regexp = new RegExp(prefix + ‘(\\d+)’), matches = el.className.match(regexp), result = (matches¹) ? matches¹ : false; return result;
}

Markup:

<a href=”/somewhere” class=“random i-14555”>My Link</a>

Call the function:

var number = getNumberFromClassName(myLink, ‘i-’);
// number equals 14555

Hope this is useful to someone… sorry textile bc. codeblocks do not work here…
