When we need to get the html string from some DOM component we extracted from its parent, (eg: sortable helper), then we can convert that string to jquery object first.

example:

var thehtml = $(ui.helper).html();
    thehtml = $(thehtml); // convert to jquery object
    thehtml.addClass("yourClass"); // we can then assign new class

    ui.helper.replaceWith(thehtml); // do something you want with it

In your case

var someVar = '<i class="firstClass"></i>'; // Html Markup to be used later.
    someVar = $(someVar); // convert to jquery object
    someVar.addClass('secondClass');

You can do it in three ways:

  1. You let your HTMl markup execute first so that you can get as an DOM element and manipulate it.
  2. The hard and ugly way, treat the markup as a string and manipulate the string using 'substring' and/or 'slice'.

  3. Break up the markup and keep it in an array of strings, say array[0] = i class=; array[1] = firstClass; array[2] = /i>;

    (i m new to stackoverflow and hence dnt knw how to write HTML in the answer, but i hope u got what i m tryin to explain) Then you can add as many classes as you want by simply concatinating the classname to a array[1](array[1] += ' classname'). And when you actually want to use it, reform the whole markup by addind all the bits. It is still ugly, but you will atleast get what you want.

You can only use addClass on a HTML element so you need to set your variable to be a DOM element (e.g. $('<i>')):-

var someVar = $('<i>', {'class': 'firstClass'});
someVa.addClass('secondClass');
