check if string contains a number

Question

I need to use jquery 1.3.2 and would like to check if a string inside element contains a number. If not an alert should popup. Here is my code but it does not work. What is wrong with it? thank you

$(document).ready(function () {

var val = $(".xxx").val();   
var matches = val.match(/\d+/g);
if (matches != null) {
alert('number');
} 
});

html

<div class="xxx">aaa</div>

The element doesn't contain a number ? – adeneo Nov 27 '13 at 17:04 — adeneo, Nov 27 '13 at 17:04
Also the element has no value, it's a **DIV** – adeneo Nov 27 '13 at 17:06 — adeneo, Nov 27 '13 at 17:06

Use .html() or .text(), not .val(). .val() is for input elements:

var val = $(".xxx").html();
