Checkbox not being checked when running function

I have a checkbox that when it is clicked it submits the form to the server to store the detail. All works fine except that after the form is submitted I update a div to say submitted but the checkbox isn't ticked. The page isn't refreshed of course and upon page refresh it is ticked.

I thought I might be able to check the box myself as I'm using jQuery but I have a lot of these checkboxes each with a dynamic name so I'm not sure how I would call them. I thought something like:

$('input[name=("favourite" + id)]').attr('checked', true);

might work but no luck. If I don't call the function on the checkbox being ticked the checkbox behaves normally.

Thanks for anything that could help.

Try doing

$('input[name=("favourite" + id)]').checked = true;

instead.

The issue may be that setting the attribute is not automatically interpreted by your browser as changing the DOM property. This is a bit confusing, but on browsers like Firefox, etc, HTML attributes and DOM properties are stored separately (most are named the same, but there are exceptions - such as the class attribute being represented by the className property).

Changing properties affects the behavior of the Elements, while attributes do not always have the same effect - on some browsers they are only parsed during initial render.

You should break your string in order to introduce the value of the id variable into your selector, you can do it like this:

$('input[name="favourite' + id + '"]').attr('checked', true);
