Alternative to jQuery contains() Selector - is there an is() or equals() Selector?

Caveat: I'm not a developer, I'm a designer.

From this answer I learned of the :contains() selector.

I used this selector like this:

jQuery(document).ready(function() {
    jQuery("td:contains('No')").css("background-color", "#FFBFBF");
});

However, this selects td cells containing Not, which I don't want to happen.

I found there is a .filter() selector from this answer, but I'm not a programmer, and do not understand how to apply .filter() to my jQuery code, so I'm wondering if there is something that functions like an is() or equals() selector?
