谁能将以下jQuery代码翻译成原生态JS代码[有点难度]
function fileQueued(file)//队列添加成功
{
for(var i in selQueue)if(selQueue[i].name==file.name){swfu.cancelUpload(file.id);return false;}//防止同名文件重复添加
if(selQueue.length==0)$('#controlBtns').show();
selQueue.push(file);
allSize+=file.size;
$('#listBody').append('<tr id="'+file.id+'"><td>'+file.name+'</td><td>'+formatBytes(file.size)+'</td><td id="'+file.id+'_state">就绪</td></tr>');
$('#'+file.id).hover(function(){$(this).addClass('hover');},function(){$(this).removeClass('hover');})
.click(function(){selectID=file.id;$('#listBody tr').removeClass('select');$(this).removeClass('hover').addClass('select');$('#btnClear').show();})
}

又遇到table动态添加行，搞不定呀

[解决办法]

JScript code

        function fileQueued(file)//队列添加成功        {            for(var i in selQueue){                if(selQueue[i].name==file.name){                    swfu.cancelUpload(file.id);                    return false;                }//防止同名文件重复添加            }            if(selQueue.length==0){                $('#controlBtns').show();            }            selQueue.push(file);            allSize+=file.size;                        var listBody = $("listBody"),                tr = createElement("tr"),                td_1 = createElement("td"),                td_2 = createElement("td"),                td_3 = createElement("td"),                el = $(file.id);            td_1.innerHTML = file.name;            td_2.innerHTML = formatBytes(file.size);            td_3.id = file.id + "_state";            td_3.innerHTML = "就绪";            tr.id = file.id;            tr.appendChild(td_1);            tr.appendChild(td_2);            tr.appendChild(td_3);            listBody.appendChild(tr);                        addEventListener(el, "click", function(){                selectID=file.id;                var trs = $$("tr");                for(var i = 0, len = trs.length; i < len; i++){                    removeClass(trs[i], "select");                }                removeClass(this, "hover");                addClass(this, "select");                var btnClear = $("btnClear");                btnClear.display = "";            });            addEventListener(el, "mouseover", function(event){                var relatedElement = event.relatedTarget || event.fromElement;                if(!contains(this, relatedElement){                    addClass(this, "hover");                }            });            addEventListener(el, "mouseout", function(event){                var relatedElement = event.relatedTarget || event.toElement;                if(!contains(this, relatedElement){                    removeClass(this, "hover");                }            });        }                function $(id){            return document.getElementById(id);        }        function $$(tagName){            return document.getElementsByTagName(tagName);        }        function createElement(tagName){            return document.createElement(tagName);        }        function contains(elem1, elem2){            if(elem1 === elem2){                return true;            }            var parent = elem2.parentNode;            while(parent && parent !== document){                if(parent === elem1){                    return true;                }else{                    parent = parent.parentNode;                }            }            return false;        }        function addEventListener(el, type, fn){            if(el.addEventListener){                el.addEventListener(type, fn, false);            }else if(el.attachEvent){                el.attachEvent("on" + type, function(){                    fn.call(el, window.event);                });            }        }        function addClass(el, clz){            var className = el.className,                reg = new RegExp("\\b" + clz + "\\b");            if(className === ""){                el.className = clz;            }else if(!reg.test(className)){                el.className += " " + clz;            }        }        function removeClass(el, clz){            var reg = new RegExp("\\b" + clz + "\\b");            if(reg.test(el.className)){                el.className = el.className.replace(reg, "").replace(/\s{2,}/g, " ");            }        }
