JQuery - How to select elements that do not have a class?

Question

How to get elements that don't have class names?

        <td class="B A">A03<sub>reserved</sub></td>
        <td class="B R">R70</td>
        <td>105</td>
        <td class="M C">L220</td>

I'm doing it now $('td').not('.A, .B, .C, .M, .R')

There must be a better way!

Answer 1

You can use an attribute selector with an empty value:

$('[class=]')

Answer 2

how about this:

$("td:not([class])")

not sure if this will work for something like:

<td class="">

Answer 3

One way to do this is to use filter():

$("td").filter( function() {return this.className=='';} )
