jQuery From Input Update

I have a form that I would like to change the value of an input by it's name. For some reason I'm having an issue with targeting the name:

<script>
$( 'input[name="item[0][total"]' ).val( damage_total );
</script>

<html>
<input type="text" value="296" name="item[0][total]">
</html>

I'm not great at jquery - still using old fashion javascript. But it looks like your apostrophes' are out of place. I think your line 2 should read:

$( 'input[name="item[0][total]"' ).val( damage_total );

Open in new window

I hope it is that simple.

You need to escape the array brackets:

$('input[name=item\\[0\\]\\[total\\]]' ).val( damage_total );

Hi,
I guess just a simple typo - there was one closing bracket missing:

$( 'input[name="item[0][total]"]' ).val( damage_total );

Open in new window

But you should reconsider to change your element names as I doubt that brackets are allowed characters.

@Rainer - brackets are allowed in inputs and actually I'd strongly recommend them - they're an easy way to group form data - making the POST processing much simpler
