Answer 1

使用属性等于选择器

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

Answer 2

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')
