Radio button value vits jquery

I have a test form where my radio button have text and value.

I'm trying to pass text from label from checked radio button to hidden field name=form[test]

this is my function:

    var levels = $('input[name="form[Button]"]:checked + label').map(function() {
return $(this).text();
}).get();

$('input[name="form[test]"]').change( function() {
($(this).val(levels));
});

HTML

<input type="radio" id="Button0" value="0" name="form[Button]">
<label for="Button0">This item is worth £0</label>
<input type="radio" id="Button1" value="100" name="form[Button]">
<label for="Button0">This item is worth £100</label>

<input type="hidden" valu开发者_如何学Pythone="" id="test" name="form[test]">

Try it this way:

$('input[name="form[Button]"]').each(function() {
    $(this).data('label', $(this).next('label').text());
});

$('input[name="form[Button]"]').change(function() {
    $('input[name="form[test]"]').val($(this).data('label'));
});

$('input[name="form[Button]"]').change(function() {
    var level = $('input:radio[name="form[Button]"]:checked + label').text();
    $('input[name="form[test]"]').val(level);
});

And you can see a live demo.

This

$('input[name="form[test]"]').change( function() {
($(this).val(levels));
});

means that you only want to change the value of the hidden input when it already changes by some other influence. I think you mean:

var levels = $('input[name="form[Button]"]:checked + label').map(function() {
    return $(this).text();
}).get();

$('input[name="form[test]"]').val(levels);
