I just reversed my question to get the required output. Here by reading the class name,I am getting the element name using the below JS:

     var elementName = "";
        var dd = document.getElementsByClassName("CheckBox");
        for (i = 0; i <= dd.length - 1; i++) {
            if (elementName == "")
            { elementName = dd[i].name; }
                elementName = elementName + "," + dd[i].name;
