照著打的js文件卻沒(méi)效果出來(lái)？？
function?bind(el,eventType,?callback){
????if(typeof?el.addEventListener?===?"function"){
???????????el.addEventListener(el,eventType,?callback,false);
????????}else?if(typeof?el.attechEvent?===?"function"){
???????????el.attechEvent("on"?+?eventType,callback);
????????????}
????}
?????
function?mouseoverHandler(e){
????var?target?=?e.target?||?e.srcElement;
????var?outer?=?document.getElementById("subject");
????var?list?=?outer.getElementsByTagName("li");
?????
????for(var?i=0;?i<list.length;?i++){
????????list[i].className?=?"";
????????}
?????
???????while(target.tagName?!=?"LI"?&&?target.tagName?==?"body"){
?????????????target?=?targt.parentNode;
???????????}?
???????target.className?=?"big";
?????
????}
?
?
function?initList(){
????var?outer?=?document.getElementById("subject");
????var?list?=?outer.getElementsByTagName("li");
????for(var?i=0;?i<list.length;?i++){
?????????bind(list[i],"mouseover",?mouseoverHandler);
???????}
????}
?????
initList();然后HTML文件中引用就是這樣子：
<!DOCTYPE?html> <html> <head> <meta?charset="utf-8"> <link?rel="stylesheet"?type="text/css"?href="index.css"> <title>手風(fēng)琴效果</title> <script?type="text/javascript"?src="index.js"></script> </head> <body> 省略…… </body> </html>
監(jiān)聽(tīng)和縮放的效果都沒(méi)有出來(lái)，為什么

沒(méi)有運(yùn)行過(guò)試試 el.attechEvent拼寫(xiě)錯(cuò)誤 attachEvent?
target.tagName?==?"body" body大寫(xiě)試試BODY
