jQuery change input box by preceding label

Question

I have the following bit of HTML:

<label>First Name</label><input name="Question62" type="text" value="" />

Unfortunately because I am creating several forms, the "name" of the input box will change however the "label" contents will stay the same ("First Name").

Is there a way to change the input value by the preceding label? (instead of an id tag in the input box)?

[Edit] Answer given below, code provided in case anyone needs it:

var firstName = $("label:contains('First Name')");
firstName.next('input').val(obj.first_name);

Answer 1

Try like this:

var labelContent = "First Name";
$('label:contains('+labelContent+') ~ :text')​.val( 'Some value' )

Answer 2

You want jquery .next() method.
