CSS "id" and "class" syntax in javascript

I have a box defined like this:

the innermost "container" is where content appears.

I have to pass the id of "container" to the javascript variable parameter
"target":

How do I replace "target" with the full id of "container", that is what would the correct syntax for "target" be?

I tried many variations but could not come up with one that works, tho this must be a simple one for the experts here.

If it's as you've described, it should be "shadow-container1". If that doesn't work, give a link to the Ajax-tab code that you're using.

acoder,

As "target" has to resolve to "#shadow-container1 .container", the # alone does not work.

I don't understand what you mean by "give a link to the Ajax-tab code that you're using".

I did a quick search and found that you're using the Dynamic Drive Ajax Tabs. OK, you need to pass the ID, so the easiest way is to give the container a unique ID:
and pass that ID.

So I gave every div in the group a unique ID, doing away with the "class"es alltogether. This made the script happy!

Does this mean id+class combinations cannot be used in JS in general, or is this peculiar to the script in question?

Thank you and cheers.

They can be used together, but the script required a unique ID. IDs are unique whereas classes are not. Sometimes you want some CSS rule/script to apply to a set of elements, so you use one class for all of them, but you also want to refer to a particular element for some rule and giving a unique ID makes sure of that. You can refer to a particular element without IDs, e.g. by using getElementsByClassName() and then indexing the correct one, but in this case, that wouldn't have worked.

jQuery supports mixed searches just like css.
