这次在开发过程中用到了模态弹出对话框,但这个函数会有缓存,很是烦恼,在网上查了查相关的资料,发现了一种解决的方法,在这里记录下,主要是在给弹出的窗口的页面加上个时间参数,这样就不会有缓存了,如下:
一、缓存
1、
<meta http-equiv="pragma" content="no-cache" />
<meta http-equiv="Cache-Control" content="no-cache,must-revalidate" />
<meta http-equiv="expires" content="Wed,26 Feb 1997 08:21:57 GMT" />
2、
<script language='javascript'>
var time = new Date();
window.showModalDialog("newWin.html?time="+time,"","");
</script>
二、返回值
1、被调用的fish.html
<html>
<title>html</title>
<head>
<script>
function sendTo() {
window.returnValue = “deepfish”;
window.close() ;
}
</script>
</head>
<body>
<form>
<input value="返回" type=button onclick="sendTo()">
</form>
</body>
</html>
2、调用者html
<html>
<body>
<script>
var tmp = window.showModalDialog("fish.htm")
alert(tmp);
</script>
<body>
</html>
