There should be a ~= selector to select elements with an exact match where attribute values are separated by spaces. For example, suppose I have this HTML fragment:

<div class="button on"></div>

<div class="button off"></div>

I would expect to select the "on" element with this:

$("div[class~=button][class~=on]");

The *= selector is similar, but fails in this example because the word "button" contains "on". Alternatively, this works:

$("div[class*=button on]");

But that requires attribute values to be in a specific order, which is not desirable.
