<script type="text/javascript">
function checkWin()
{
if(myWindow.closed)
{
document.write("closed")
}
else
{
document.write("opened")
}
}
</script>
</head>
<body >
<script type="text/javascript">
myWindow=window.open('','','width=200,height=100');//就是这里，我想在myWindow=前加上var 如var myWindow= ,就会出错，应该如何写呢？？
myWindow.document.write("This is 'myWindow'");//window.open产生是什么东西呢？？如何定义它呢
</script>
<input type="button" value="点击出现窗口" onclick="checkWin()"/>
</body>
</html>
上面的代码是好的，只是我想学透一些。就在myWindow=window.open前加了var myWindow=window.open,所以出了错，想问js的朋友，myWindow前加什么呢能不出错。
答对了立即给分的
