Question

I have a number of CSS attributes and Classes which get applied based on where the element appears in the HTML.

However some elements do not equal any of these values so i want to be able to check which elements in a DIV do not have a background set via CSS then apply a background.

Something like:

$('.divclass:has('background')').addClass('IneedaBG.gif');

Or

$('.divclass:has(not:class1,class2,class2)').addClass('IneedaBG.gif');

Answer 1

I’m not sure class names can have a dot (IneedaBG.gif). Imagine if you tried to select this with a selector:

$(".IneedaBG.gif")

I’m pretty sure this wouldn’t work. Is it possible you want a CSS class with the image defined in the properties?

Also, you can speed up your selector performance a little, as direct reference to the .divclass class will scan the whole DOM:

$("div.divclass:has('background')").addClass("IneedaBG");

Try also using ” for the selectors, instead of having multiple ‘

Can you have an ID for the DIV? That would be even better!
