AND/OR in IF condition?

Is it possible to use a Logical AND or OR within an IF condition? Something like:

onclick="if(
	     			             	var1==value1 OR var1==value2 ,action(dothis)
	     			             	else,action(dosomethingelse);
	     			             	)
	     			              	;
                       			"

I tried, but I didn't succeed so far. If this is not possible, is there some workaround? What about using "case". How is the right syntax with that then?

Thank you very much in advance.

Well,

A workaround only, still searching for the AND/OR solution:

onclick="
	     				set(not-ok,false);
	     				if(
	     				var1==val1,set(not-ok,true)
	     				);
	     				if(
	     				var1==val2,set(not-ok,true)
	     				);
	     				if(not-ok == TRUE ,action(notokaction)
	     				else,action(okaction);set(not-ok,false);
	     				)
	     				;
	     			"

I have the feeling, that this is quite strange coding, but it is working at least. Would love to hear about a better solution

Ok, Thanks a lot for clarifying this to me, Michel.

I admit, your exampel looks already a bit more after proper coding

Anyhow, maybe Klaus is giving us this feature one day
