Question

I am currently working on a javascript and php project. I have a checkbox array that have the same id chkCategory and the name chkCategory[]. I then have PHP return some json that contains the various categories and I want to set each checkbox checked attribute for each category that was in the json. The only thing that identifies each checkbox is the value. I.e. the json may have a value MyCategory so the checkbox that has the value MyCategory should be set.

I know you can use $("#myCheckBoxId").attr("checked", true) for an individual checkbox but not sure how to do this for a specific checkbox with a certain value.

Thanks for any help you can provide.

You can use standard CSS attribute selectors in JQuery. For example:

$("input[value=MyCategory]")

will select the input tag with attribute value=MyCategory. If there are different types of inputs with that value, you could also select on type=checkbox:

$("input[type=checkbox][value=MyCategory]")
