Use the Attribute Equals Selector

alert($("input.Position[value='4']").attr("id"));

First, you have to take off the '#' from your id's.

<input type="Text" id="34" value="1" class="Position">

Then you can find the input you are looking for with the following selector:

$('input.Position[value=4]').attr('id')

You should put the tag name before any class declarations in the selector - speeds it up. Probably insignificant in this case, but a good practice to get into. $('input.Position[value=4]').attr('id')
