net网站 JS脚本 Javascript 脚本 document.all[..] 为空或者不是对象 要怎么解决？

//单选按扭(单击事件,含复选框)
function RadioClick(Listid,ListCN,ListEN)
{
var dom = document.all;
var el = event.srcElement;

if(el.tagName=="INPUT"&&el.type.toLowerCase()=="radio")
{
for(i=0;i<dom.length;i++)
{
if(dom[i].tagName=="INPUT" && dom[i].type.toLowerCase()=="radio")
{
dom[i].checked=false;
}
}
}
el.checked=true;

//初始化复选框
for(var i=0;i<document.all.length;i++)
{
if(document.all[i].name!=null)
{
if(document.all[i].name.indexOf("chk_CnResume") > 0)
{
document.all[i].disabled = true;
document.all[i].checked = false;
}

if(document.all[i].name.indexOf("chk_EnResume") > 0)
{
document.all[i].disabled = true;
document.all[i].checked = false;
}
}
}

//设置选择的复选框
if(ListCN == "1")
{
document.all["lit_ResumeList__ctl"+" Listid" +"_chk_CnResume"].checked = true;
document.all["lit_ResumeList__ctl"+ Listid +"_chk_CnResume"].disabled = false;
}
if(ListEN == "1")
{
document.all["lit_ResumeList__ctl"+ "Listid" +"_chk_EnResume"].checked = true;

}

//页面复选框初始化
function PageChkLoad()
{

//改变附求职信
function LetterChanged()
{
var obj = document.all["chk_Letter"];

if (obj != null)

document.all['txt_Letter'].disabled = true;
}
else
{

document.all['txt_Letter'].disabled = false;
}
}

}

//选择求职信
function ChangeLetter(LetterCount)
{
var letterID= "";
var title ="";
var selectedIndex = "";

letterID = document.all['ddl_Letter'].value;

selectedIndex = document.all['ddl_Letter'].selectedIndex;

title = document.all['ddl_Letter'].options[ selectedIndex ].text;

for (var i=1;i<=LetterCount;i++)
{
if(document.all["Hidden" + letterID] != null)
{
document.all.txt_Letter.value = document.all["Hidden"+letterID].value.replace(/</g,"<").replace(/>/g,">").replace(/"/g,"\"").replace(/&/g,"&");
}
else
{
document.all.txt_Letter.value="";
}
}
}
//单选按扭(单击事件,不含复选框)
function RadioClick2(Listid)
{
var dom = document.all;
var el = event.srcElement;

if(el.tagName=="INPUT"&&el.type.toLowerCase()=="radio")
{
for(i=0;i<dom.length;i++)
{
if(dom[i].tagName=="INPUT" && dom[i].type.toLowerCase()=="radio")

dom[i].checked=false;
}
}
}
el.checked=true;
}
