网站繁简切换的JS遇到页面卡死的解决方法

公司打算进入台湾市场，最近开发了繁体版本的网站，数据库里的信息全是简体，除了网页上固定的文字手动翻译了，文章内容标题都不是繁体。

于是在网上找了一段比较流行的繁简切换的JS实现了，不过后来却发现，有些页面会卡死，根本无法执行下去。弹出信息表明都是这个繁简切换的JS带来的问题。

仔细查看了下，发现原来是这个问题。分享下，也许有不少人遇到类似的问题。

先上代码：

//模仿语言包式的简繁转换功能插件！ var Default_isFT = 0 //默认是否繁体，0-简体，1-繁体 
var StranIt_Delay = 50 //翻译延时毫秒（设这个的目的是让网页先流畅的显现出来） 
//－－－－－－－代码开始，以下别改－－－－－－－ 
//转换文本 
function StranText(txt,toFT,chgTxt) 
{ 
if(txt==""||txt==null)return "" 
toFT=toFT==null?BodyIsFt:toFT 
if(chgTxt)txt=txt.replace((toFT?"简":"繁"),(toFT?"繁":"简")) 
if(toFT){return Traditionalized(txt)} 
else {return Simplized(txt)} 
} 
//转换对象，使用递归，逐层剥到文本 
function StranBody(fobj) 
{ 
if(typeof(fobj)=="object"){var obj=fobj.childNodes} 
else 
{ 
var tmptxt=StranLink_Obj.innerHTML.toString() 
if(tmptxt.indexOf("简")<0) 
{ 
BodyIsFt=1 
StranLink_Obj.innerHTML=StranText(tmptxt,0,1) 
//StranLink.title=StranText(StranLink.title,0,1) 
} 
else 
{ 
BodyIsFt=0 
StranLink_Obj.innerHTML=StranText(tmptxt,1,1) 
//StranLink.title=StranText(StranLink.title,1,1) 
} 
setCookie(JF_cn,BodyIsFt,7) 
var obj=document.body.childNodes 
} 
for(var i=0;i<obj.length;i++) 
{ 
var OO=obj.item(i) 
if("||BR|HR|TEXTAREA|".indexOf("|"+OO.tagName+"|")>0||OO==StranLink_Obj)continue; 
if(OO.title!=""&&OO.title!=null)OO.title=StranText(OO.title); 
if(OO.alt!=""&&OO.alt!=null)OO.alt=StranText(OO.alt); 
if(OO.tagName=="INPUT"&&OO.value!=""&&OO.type!="text"&&OO.type!="hidden")OO.value=StranText(OO.value); 
if(OO.nodeType==3){OO.data=StranText(OO.data)} 
else StranBody(OO) 
} 
}

起初我以为是那个递归的问题引起的，但是测试发现就算是很多字符，它仍然能快速的进行替换。

经过排查，原来是JS和OBJECT标签会带来卡死的问题。繁简切换实现必然会跳过某些标签，看到这段，它的作用就是来判断替换哪些标签里的文字。

for(var i=0;i<obj.length;i++) 
{ 
var OO=obj.item(i) 
if("||BR|HR|TEXTAREA|".indexOf("|"+OO.tagName+"|")>0||OO==StranLink_Obj)continue; 
if(OO.title!=""&&OO.title!=null)OO.title=StranText(OO.title); 
if(OO.alt!=""&&OO.alt!=null)OO.alt=StranText(OO.alt); 
if(OO.tagName=="INPUT"&&OO.value!=""&&OO.type!="text"&&OO.type!="hidden")OO.value=StranText(OO.value); 
if(OO.nodeType==3){OO.data=StranText(OO.data)} 
else StranBody(OO) 
}

加上这个就一切正常了：

if(OO.tagName=="OBJECT")continue; 
if(OO.tagName=="SCRIPT")continue;
