帮忙给调试一下js，另求教调试工具和方法，书籍！
先来代码
displayAttreviations.js

JScript code


// JavaScript Document
function displayAbbreviations(){
    if(!document.getElementsByTagName||!document.createElement||!document.createTextNode) return false;
    //get abbr
    var abbreviations = document.getElementsByTagName("abbr");
    if(abbreviations.length<1) return false;
    var defs = new Array();
    //do all abbr
    for(var i=0; i<abbreviations.length;i++){
        var current_abbr = abbreviations[i];
        var defition = current_abbr.getAttribute("title");
        var key = current_abbr.lastChild.nodeValue;
        defs[key] = defition;
        }
        //create defition list
        var dlist = document.createElement("dl");
        //do all defition
        for(key in defs) {
            var defition = defs[key];
            var dtitle = document.createElement("dt");
            var dtitle_text = document.createTextNode(key);
            dtitle.appendChild(dtitle_text);
            //create defition description
            var ddesc = document.createElement("dd");
            var ddesc_text = document.createTextNode(defition);
            ddesc.appendChild(ddesc_text);
            //add them to defition list
            dlist.appendChild(dtitle);
            dlist.appendChild(ddesc);
            }
            //create title
            var header = document.createElement("h2");
            var header_text = document.createTextNode("Abbreviations");
            header.appendChild(header_text);
            //add title to document body
            document.getElementsByTagName("body")[0].appendChlid(header);
            //add defition list to document body
            document.getElementsByTagName("body")[0].appendChlid(dlist);
}
addLoadEvent(displayAbbreviations);

addLoadEvent.js

JScript code


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