How can you concatenate two variables in jquery?

Question

Can I do the following to concatenate two variables into one? Or there is a better way to do it?

   $('.row-add').live("click", function () {
          var newContent = $("<span>Example data</span>"+"");
          var newContent2 = $("<span>New Project</span>");
          var content = newContent+newContent2;
          $(this).closest("td").append(content);
        });

Answer 1

You can use .add

content = newContent.add( newContent2 );
