Question

I would like to find all elements inside a container that have a certain data attribute set to 1 as well as all elements that don’t have this attribute set at all.

The data attribute is as follows:

$("#element").data("activate")

It can have a value of 1 or 0. If an element doesn’t have an “activate” data property set I want to treat it as a 0.

I have the following code at present:

$("#content").find("[data-activate='0']").off();

However I would also like to do something like this:

$("#content").find("all where data-activate NOT exists").off();

ie if an element doesn’t have the attribute even set.

Answer 1

You can use :not:

$('#content :not([data-activate])').off();

Or filter():

$('#content div').filter(function() {
    return !$(this).attr('data-activate');
}).off();
