    To load a .js or .css file dynamically, in a head section, it means using DOM methods to first create a new "SCRIPT" or "LINK" element, assign it the appropriate attributes, and finally, use element.appendChild() to add the element to the desired location within the document tree. It sounds a lot more fancy than it really is. Lets see how it all comes together

    <script type="text/javascript">
    // function
    function loadheadfile(filename, filetype){
    		var fileref=document.createElement('script')
    		fileref.setAttribute("src", filename)
    	else if(filetype=="css") {
    		var fileref=document.createElement("link")
    		fileref.setAttribute("rel", "stylesheet")
    		fileref.setAttribute("type", "text/css")
    		fileref.setAttribute("href", filename)
    	if(typeof fileref!="undefined")
    // call function
