var iframeDiv=document.getElementById("DivId")
document.body.removeChild(iframeDiv)
如果是模态窗口弹出<form name="form1">
<input type="text" name="fag1">
<input type="text" name="fag2">
</form>
function shw(){
var url="open.html"
//----------方法一--start-------
var obj=document.form1//指定页面对象
var returnValue=window.showModalDialog(url ,obj,'dialogHeight:550pxdialogWidth:500pxcenter:yes')//方法返回值
//----------方法一--end-------
alert(returnValue)
}
如果是非模态窗口弹出,那么
<script type="text/javascript">
//弹出窗口
function openwin(url,width,height){
var l=window.screen.width
var w= window.screen.height
var al=(l-width)/2
var aw=(w-height)/2
var OpenWindow=window.open(url,"弹出窗口","toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=yes,width="+width+",height="+height+",top="+aw+",left="+al+"")
OpenWindow.focus()
if(OpenWindow!=null){ //弹出窗口关闭事件
//if(window.attachEvent) OpenWindow.attachEvent("onbeforeunload", quickOut)
if(window.attachEvent) OpenWindow.attachEvent("onunload", quickOut)
}
}
//关闭触发方法
function quickOut()
{
alert("窗口已关闭")
}
</script>
<input type="button" value="ok" onclick="openwin('open.html','600','500')">
<input type="text" name="txt0" id="txt0">注意:firefox这里一定要写ID属性,不然取不到值
