点击表单里的按钮后，这个按钮立即就变灰了
用cs代码的enabled=false在页面提交并返回之前是不会立即有效果的！除非用js。
      如果是提交表单，可以在submit按纽事件里写document.all.button1.disabled=true;
如果是imagebutton，在js里设置按纽的width=0

<script   language="javascript">
//----------只提交一次cmdbutton一般是immagebutton
function   submitonce()
{
                    var   cmdbutton=document.all.imagebutton1;
if(cmdbutton   !=   null)
{
cmdbutton.clearattributes();
cmdbutton.width=0;
}
}
if(document.all.imagebutton1!=null)
document.all.imagebutton1.onclick   =   submitonce;
</script>
</body>
<html><head><script type="text/javascript">function disable()  {  document.getElementById("mySelect").disabled=true  }function enable()  {  document.getElementById("mySelect").disabled=false  }</script></head><body><form><select id="mySelect">  <option>苹果</option>  <option>桃子</option>  <option>香蕉</option>  <option>桔子</option></select><br /><br /><input type="button"  value="禁用列表"><input type="button"  value="启用列表"></form></body></html> <html><head><script type="text/javascript">function alertId(){var txt="Id: " + document.getElementById("myButton").idtxt=txt + ", type: " + document.getElementById("myButton").typealert(txt)document.getElementById("myButton").disabled=true}</script></head><body><form><button id="myButton" >请点击我！</button></form></body></html> <input type="image" src="http://51js.com/images/default/newtopic.gif"  />
