title: jQuery - check whether string contains numeric value
body: <p>How to check whether a string contains any numeric value by jquery? </p>
  
  <p>I search through many examples but I only get the way to check for a number, NOT number in a STRING. I am trying to find something like <code>$(this).attr('id').contains("number");</code> </p>
  
  <p>(p/s: my DOM id will be something like <code>Large_a</code> (without numeric value) , <code>Large_a_1</code> (with numeric value), <code>Large_a_2</code>, etc.)</p>
  
  <p>What method should I use?</p>
