Question

I have an element:

input name="crd[69][qty]" id="crd[69][qty]" value="1" size="4" class="input-text qty" maxlength="12"

Ii had mentioned the name in array format to be use in background PHP, what I need to achieve is:

• When user clicks on this textbox , I should be able to retrieve only “69” from the id of the element which is "crd[69][qty]". This id will be varying for different textboxes…

Is there any jQuery function to accomplish this?

I’m not a regex expert but this should work:

$('input').click(function(){
    var id = $(this).attr('id');
    var parts = id.match(/\[([0-9]+)\]\[([a-z]+)\]/);
    alert(parts[1] + ' - ' + parts[2]);
});
