[javascript] Set value of hidden input with jquery

I'm trying to set the value of the hidden field below using jQuery.

<input type="hidden" value="" name="testing" />

I'm using this code:

var test = $("input[name=testing]:hidden");
test.value = 'work!';

But its not working. What's wrong with my code?

This worked for me:

$('input[name="sort_order"]').attr('value','XXX');

You should use val instead of value.

<script type="text/javascript" language="javascript">
$(document).ready(function () { 
    $('input[name="testing"]').val('Work!');
});
</script>

To make it with jquery, make this way:

var test = $("input[name=testing]:hidden");
test.val('work!');

Or

var test = $("input[name=testing]:hidden").val('work!');

See working in this fiddle.

var test = $('input[name="testing"]:hidden');
test.val('work!');

You don't need to set name , just giving an id is enough.

<input type="hidden" id="testId" />

and than with jquery you can use 'val()' method like below:

 $('#testId').val("work");

Suppose you have a hidden input, named XXX, if you want to assign a value to the following

<script type="text/javascript">

    $(document).ready(function(){
    $('#XXX').val('any value');
    })
</script>

$('input[name="testing"]').val(theValue);
