关于IE6和IE7关闭窗口时提示和不提示以及上传图片前的本地预览解决办法

1 IE6和IE7关闭窗口时提示和不提示
2 上传文件立即显示效果图，在ie7中可以用滤镜

function CloseWin() //这个会提示是否关闭浏览器

{

window.opener=null;

window.open("","_self");

window.close();

}

如果在框架中关闭整个框架页面的话如下

这个是不提示关闭

function aa ( )

{

if (window.confirm('您确认要退出系统吗？'))

{

top.opener=null;

top.open("","_self");

top.close();

window.close;

}

else

{return false;}

}

function Preview(imgFile)

{

document.getElementById("pic").filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = imgFile.value;

}

</script>

<a href="javascript:CloseWin();"> 点击这里无提示关闭当前窗口</a><br />

请选择要预览的图片：<input type="file" onchange="javascript:Preview(this);" /><br />

获取图片的大小
var img=new Image();
img.src=imgFile.value;
alert(img.fileSize);
alert(img.width);
alert(img.height);

@弦音
你可以参考一下 http://blogmover.redv.com 是怎么实现的。

//if (window.addEventListener) {
// window.addEventListener("beforeunload", doClose, false);
//}
//else if (window.attachEvent) {
// window.attachEvent("onbeforeunload", doClose);
//}
//else {
window.onbeforeunload = doClose;
//}
function doClose() {
var t = "───────────────────────\r\n您确定要离开 Blog Mover 吗？\r\n确定后未完成的操作你将无法控制。\r\n───────────────────────";
return t;
}

I've had the same issue... and did a bit of research on my own to see if I could find a work-around for this.

I have created a simple testing example online to try out different methods of opening new windows and having them self-close: http://sky.prohosting.com/savage25/AutoCloseExample.html
As you can see from the descriptions within it, IE6 and IE7 react differently in several of the cases. Hence the "issue" that IE7 has created...

In particular, the one that is causing me issues is the FORM submission using a "_blank" target window. It closes without confirmation in IE6, but does not in IE7.

A work-around that I discovered: IE7 may actually have become less secure when JAVASCRIPT redirects the current page (within the same window), and then this redirected-to site closes the window... the page then closes without any confirmation. I was able to use this "bug" (?) to my advantage as a work-around to solve the problem.

Instead of calling "window.close()" to close the current window... do this:

window.open('close.html', '_self');

Where "close.html" contains:

<html><body>
<script language="JavaScript">window.close();</script>
</body></html>

This should work in both IE6 and IE7 to close the current window without confirmation.
I am currently using it in my application and it works well.

ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "提示", "window.opener=null;window.open('', '_self');window.close()", true);
