一段JS代码和JQUERY代码冲突了。求帮我改一下下

HTML code


function $(id) { return document.getElementById(id); }

function addLoadEvent(func){
    var oldonload = window.onload;
    if (typeof window.onload != 'function') {
        window.onload = func;
    } else {
        window.onload = function(){
            oldonload();
            func();
        }
    }
}

就是这段。和我其他代码段中的JQUERY冲突了。
能不能将它改成 JQUERY的形式
