英文译文中的错误在哪里?
原标题:Where is the error IE is finding in this script?

IE继续给我留下下至最后一行的错误,称“目标需要”。 我不敢确定这个问题在哪里。 任何建议?

function showdiv()
{
  document.getElementById("dialogue").style.display = "";
  document.getElementById("screen").style.display = "";
  document.getElementById("screen").style.width = getBrowserWidth();
}
function hidediv(opt){
if(opt=="agree"){
  document.Annexation.checkbox.checked = true;
  document.getElementById("dialogue").style.display = "none";
  document.getElementById("dialogue").style.display = "none";
  document.getElementById("screen").style.display = "none";
}else{
  document.getElementById("dialogue").style.display = "none";
  document.getElementById("screen").style.display = "none";
}}

window.onscroll = scrollEvent;
function scrollEvent() {
var y;
if (document.documentElement && !document.documentElement.scrollTop)
  // IE6 +4.01 but no scrolling going on
  y=document.documentElement.scrollTop; 
else if (document.documentElement && document.documentElement.scrollTop){
  // IE6 +4.01 and user has scrolled
  y=document.documentElement.scrollTop;
}
else if (document.body && document.body.scrollTop){
  // IE5 or DTD 3.2
  y=document.body.scrollTop;
}
  document.getElementById("screen").style.top = y+"px";
} 
最佳回答

下述一种情况可能无效:

document.getElementById("dialogue")
document.getElementById("screen")
document.Annexation
document.Annexation.checkbox

getBrowserWidth未作界定。

问题回答

document.getElementById(“屏幕”) 定义不明。 加入以下法典:

if( !document.getElementById("screen") ) alert( "Spara was right." );

如果情况并非如此,它将告诉你。

<代码>文件>中的附件格式。

你有两种办法选择检查箱。 一种办法是为检查箱的标签分配一个名称价值。

<input type="checkbox"  name="ck" />

document.getElementsByName ("ck”)[0].checked = real; to make theeck Boxecked.

另一种方法是为检查箱子的标签分配一个补贴。

<input type="checkbox"  id="ck" />

document.getElementById(“ck”)。 核对=真实;,对核对箱进行检查。
