possible to assign var and use in attr?

var myValue = "sItem-" + val;
$('#something').attr('class','myValue');

The DOM show me myValue instead of the value that I set, which I expect to see sItem-1. I console.log the myValue, but it can shows sItem-1? hmm...

I also tried $('#something').attr('class', "sItem-" + val); I doesn't work

try something like this

 var myValue = "sItem-" + val;
 $('#something').addClass('class',myValue);

Use addClass instead of attr: http://api.jquery.com/addClass/

And you uses myValue with single quotes, that's wrong:

$('#something').addClass(myValue);

You are enclosing the variable into single quotes.

Try this

$('#something').attr('class',myValue);

instead of 

$('#something').attr('class','myValue');

Or even better use .prop() instead of .attr()

$('#something').prop('class',myValue);

Or if you want to add class to an element then you can use .addClass()

$('#something').addClass(myValue);
