Pass a variable in a selector jquery

Question

I want to pass a variable in a selector jquery but I don't find the right syntaxe.

I have this :

var jsonobject = eval(responseObject);

    for(var item in jsonobject)
    {
        $('#",jsonobject[item],"').css("background-color","red");                   
    }

So the variable is jsonobject[item] and I want to use the value in it as the name of the selector.

Thanks for your help !

Side note: use `JSON.parse()`, not `eval()` to parse the JSON response. — JJJ, Aug 24 '15 at 10:36

You need to use

$("#"+jsonobject[item]).css("background-color","red");

Simply use string concatenation for that:

$('#' + jsonobject[item]).css(...);
