谷歌浏览器块时打印preVIEW打开的子窗口Ajax请求

问题描述：

有2个文件： index.html的和 print.html

首先一个包括打开 print.html 使用简单的命令按钮：

First one contains a button that opens print.html using simple command:

window.open("print.html", "_blank", "menubar=yes,toolbar=yes,status,scrollbars,resizable");

print.html 只包含一个按钮，打开打印preVIEW对话框：

print.html contains only one button that opens print preview dialog:

<button onclick="window.print();">

打开打印preVIEW对话框时出现问题。在这种情况下，对 index.html的任何行动 - 即的等的文件，该文件启动Ajax请求 - 是暂时的封锁，进入队列。只有当preVIEW关闭浏览器触发的所有请求。

The problem appears when print preview dialog is opened. In this case any action on index.html - i.e. the other file that initiate ajax request - is temporary blocked and put into queue. And only when preview is closed browser fires all requests.

我可以看到它只有在谷歌浏览器（24.0.1312.52米）。

I can see it only in Google Chrome (24.0.1312.52 m).

任何人都可以证实，这是Chrome的错误？

Can anybody confirm that this is Chrome's bug?

答

有一个Chrome浏览器的bug，其中 window.print（）不工作时，有一个标记DOM的。它可以通过调用这个函数来解决：

there is a Chrome bug where window.print() does not work when there is a tag in the DOM. It might be solved by calling this function:

function printPage() {
    window.print();

    //workaround for Chrome bug - https://code.google.com/p/chromium/issues/detail?id=141633
    if (window.stop) {
        location.reload(); //triggering unload (e.g. reloading the page) makes the print dialog appear
        window.stop(); //immediately stop reloading
    }
    return false;
}
