• 2 Did you try doing any reading on regular expressions and work yourself? – T.J. Crowder Commented Jul 25, 2012 at 9:39

$('.here').click(function(){
    var onetwo = this.className.match(/\bone-two[^\s]*/);
    console.log(onetwo[0]);
})

This should work.

$('.here').click(function(){
    var one_two = $(this).attr("class").match(/\bone-two\S*/)[0];
    alert(one_two);
    })​

Get the className of the element you clicked. And then split it. You do not need RegEx for this ;)
