js 事件合并，

Question

var onReady=function(readyCall) {
        if(document.all) {
            if(window.self==window.top) {
                (function() {
                    try {
                        document.documentElement.doScroll("left");
                    }catch(ex) {
                        setTimeout(arguments.callee,5);
                        return;
                    }
                    readyCall();
                })();
            }else {
                document.attachEvent("onreadystatechange",function() {
                    readyCall();
                    document.detachEvent("onreadystatechange", arguments.callee); 
                });
            }
        } else
            document.addEventListener("DOMContentLoaded",readyCall,false);
    }这个函数如果页面中有多个onReady时会出问题，高手帮忙修改下？
