在IE中打开一个弹出窗口 - “未找到会员” [英] opening a popup in IE - "Member not found"

问题描述

当用户打开一个在里面打开PDF的弹出窗口时，会发生这种情况。 （这部分有效）。

This happens in IE6 when the user opens a popup window that opens a PDF inside. (this part works).

然后，用户打开另一个弹出窗口，此时我收到此错误。

Then, the user opens another popup window, and at this point i get this error.

良好的描述和可能解决方案

我的问题是：

有更好的解决方案吗？打开一个窗口并立即关闭它对我来说似乎是一个愚蠢的解决方案。

Is there a better solution? Opening up a window and closing it right away seems like a silly solution to me.

推荐答案

我想我有一个更好的解决方案不涉及首先关闭窗口。问题是，如果您尝试使用空URL（即''）再次打开窗口，IE将不会覆盖窗口（PDF或其他）。但将覆盖具有非空URL的PDF。这可能是一个文件，但是关于：空白的效果更好（这通常是一个空URL）。

I think I've got a better solution that doesn't involve closing the window first. The issue is that IE won't override a window (PDF or otherwise) if you attempt to open it again with an empty URL (i.e., ''). It will override a PDF with a non-empty URL, however. That could be a file, but about:blank works even better (which is what an empty URL does normally).

根据代码的编写方式，你仍然可以想要try / catch，但这应该消除了这个需求：

Depending on how your code is written, you may still want the try/catch, but this should eliminate the need:

windowHandle = window.open('about:blank',name,attributes);
windowHandle.document.location.href = url;
windowHandle.focus();

about：blank将强制PDF退出子窗口并允许您执行所需操作做。将URL和focus（）的设置放在windowHandle.onload（）处理程序中可能不是一个坏主意，因此处理PDF时没有任何时间问题。即：

about:blank will force the PDF out of the child window and allow you to do what you need to do. It might not be a bad idea to place the setting of the URL and focus() in a windowHandle.onload() handler, so there aren't any timing issues with disposing of the PDF. I.e.:

windowHandle.onload=function(){
    windowHandle.document.location.href = url;
    windowHandle.focus();
};
