最后的分数求助||添加控件时要如何添加事件呢？

eleLayer.attachEvent("onmousedown",MDown(cra));
老说类型不匹配，why？

MDown怎样定义的，你的cra是什么？

如果访问对象（发出事件的），用this.

cra是eleLayer.setAttribute("id","cra");
MDown是一个鼠标拖动函数

用this，在函数内部用this.cra。

不对，你的cra是空间的id,那只要用this就应该可以了。

还是有问题
eleLayer.attachEvent("onmousedown",MDown(this.cra))
提示id为空或不是对象
eleLayer.attachEvent("onmousedown",MDown(this))
提示类型不匹配

一般情况下这样
   eleLayer.onmousedown=randomMoveResultLayer;//给层添加一个处理句柄
   function randomMoveResultLayer(){
     //------
   }
或者
   eleLayer.onmousedown=function {------};//给层添加一个处理句柄如果处理函数有多个参数,如下
   eleLayer.onmousedown=function { fun1(2,3,4); };//给层添加一个处理句柄
   function fun1(v1,v2,v3){
       alert(v1+v2+v3);
   }

大花猫：
attach不行吗？

<PUBLIC:ATTACH EVENT="ondetach" ONEVENT="cleanup()" />
<SCRIPT LANGUAGE="JScript">
attachEvent ('onmouseover', Hilite);
attachEvent ('onmouseout', Restore);
function cleanup()
{
detachEvent ('onmouseover', Hilite);
detachEvent ('onmouseout', Restore);
}
function Hilite()
{
if (event.srcElement == element)
{
normalColor = style.color;
runtimeStyle.color = "red";
runtimeStyle.cursor = "hand";
}
}
function Restore()
{
if (event.srcElement == element)
{
runtimeStyle.color = normalColor;
runtimeStyle.cursor = "";
}
}

eleLayer.onmousedown = MDown(cra);
提示“尚未实现”
该咋办？
应该可以添加事件的，只是麻烦点，偶不懂该是哪个属性请高人指点

上面有点乱我整理一下

</HTML>

这种定义方式不会错的
eleLayer.onmousedown = function { MDown(cra);}fucntion MDown(cra){
//------------------
}

function MDown()
{
alert("成功");
}
eleLayer.onmousedown = function { MDown(); }
为啥会提示缺少'('
请指点

成功了
应该是
function MDown()
{
alert("成功");
}
eleLayer.onmousedown = function（） { MDown(); }

还是有点问题

为啥点HTML按纽看不到添加的INPUT的onmousedown事件呢？

POSITION: absolute; TOP: 432px; HEIGHT: 24px" onclick="create()" type="button
？？？？？少了一个“"”,双银号。

我又精简了一下，能看到生成的text
<HTML>
<HEAD>
<title>title</title>
<script language="javascript">
      var i=0;
     function MDown()
      {
   alert("成功");
      } function create()
{
var cra=i+1;
var cleft = 530;
var ctop =280;
var eleInput = document.createElement("INPUT");
eleInput.setAttribute("id",cra);
//eleInput.attachEvent("onmousedown",MDown(this));//添加事件
eleInput.onmousedown = function () {MDown();}
eleInput.style.setAttribute("position","absolute");
eleInput.style.setAttribute("height","20");
eleInput.style.setAttribute("width","70");
eleInput.style.top = ctop;
eleInput.style.left = cleft;
document.body.appendChild(eleInput);
i++;
}
</script>
</HEAD>
<body >
<form id="Form1" method="post" >
<INPUT type="button" value="Create"  onclick="create()" >
  <INPUT style="Z-INDEX: 101; LEFT: 256px; POSITION: absolute; TOP: 432px" onclick="alert( document.body.outerHTML )" type="button" value="HTML">

</HTML>

attachEvent("onmousedown",MDown(this))
应为
attachEvent("onmousedown",MDown)attachEvent第二个参数是函数名称，不可以加参数和括号的。这应该是一个缺陷吧。
在HTML代码中可以用 <span onmousedown="MDown(this)">span title</span>
但在JS里却不行，不知道为什么

用attachEvent也是可以的。如下所式。
<HTML>
<HEAD>
<title>title</title>
<script language="javascript">
      var i=0;
     function MDown()
      {
   alert("成功");
      } function create()
{
var cra=i+1;
var cleft = 530;
var ctop =280;
var eleInput = document.createElement("INPUT");
eleInput.setAttribute("id",cra);
eleInput.attachEvent("onmousedown",MDown);//添加事件
//eleInput.onmousedown = function () {MDown();}
eleInput.style.setAttribute("position","absolute");
eleInput.style.setAttribute("height","20");
eleInput.style.setAttribute("width","70");
eleInput.style.top = ctop;
eleInput.style.left = cleft;
document.body.appendChild(eleInput);
i++;
}
</script>
</HEAD>
<body >
<form id="Form1" method="post" >
<INPUT type="button" value="Create"  onclick="create()" >
  <INPUT style="Z-INDEX: 101; LEFT: 256px; POSITION: absolute; TOP: 432px" onclick="alert( document.body.outerHTML )" type="button" value="HTML">
   </form>
</body>
</HTML>

同意eglic(圪圪) 的说法。给全局变量或者附加属性。
