DalekJS: Custom `hasClass` method

gistfile1.js

// _addNewFunc is just a function that adds this to the main DalekJS test at run-time

_addNewFunc("hasClass", function (__selector, __needle)
{
    // generate a random name for this element
    var name = "hasClass-" + new Date().getTime(),
        nameElem = "span#"+name;

    return this.dse_self
        .execute(function(__selector, __needle, __name)
        {
            // create a new element to house the result
            var newELEM = $('<span />').attr('id', __name).attr("data-has-class", "false");
            $("body").append(newELEM);

            // use jquery to test if the class exists
            if($(__selector).hasClass(__needle))
            {
                // it exists, change the value
                $(newELEM).attr('data-has-class', 'true');
            }
        }, __selector, __needle, name)

        // test the elem if the data is true
        .assert.attr(nameElem, 'data-has-class', 'true', __selector + " has the class, " + __needle)

        // cleanup
        .execute(function(__nameElem)
        {
            $(__nameElem).remove();
        }, nameElem);
