修改由javascript的“window.open（）”函数打开的窗口

时间：2022-10-22 15:02:57

Here's my scenario:

这是我的情景:

I have a page containing several links; each link is meant to open another window containing a pdf. The catch is, I can't have that window directly go to the PDF because I do not want to make it apparent to the end user the PDF is located on another domain, and I need to name the PDF differently than how it would regularly show up.

我有一个包含几个链接的页面;每个链接用于打开另一个包含pdf的窗口。问题是,我不能将该窗口直接转到PDF,因为我不想让最终用户明白PDF是否位于另一个域上,我需要将PDF命名为与常规用户不同的名称出现。

So then I have two pages: One is blank, and only contains a frame to be used for displaying the pdfs:

那么我有两个页面:一个是空白的,只包含一个用于显示pdf的框架:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
    <head>
        <title>[PDF]</title>
    </head>
    <frameset>
        <frame id="pdfFrame">
    </frameset>
</html>

And on the page with the links, I have the following function that calls this page (we'll call the above page "pdf.html"):

在带有链接的页面上,我有以下函数调用此页面(我们将上面的页面称为“pdf.html”):

function OpenWindow(pdfTitle, pdfLocation)
{
    var myWindow = window.open("pdf.html", "", "toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1,width=700,height=600");

    myWindow.document.title = pdfTitle; 
    myWindow.document.getElementById('pdfFrame').src = pdfLocation;
}

For the most part, this seems to work fine; however, on occasion the pop up window will not be loaded prior to the lines above that setup the title/frame source, and it will crash (or not load properly, at least).

在大多数情况下,这似乎工作正常;但是,有时弹出窗口将不会在上面设置标题/帧源的行之前加载,并且它将崩溃(或者至少没有正确加载)。

My question is, is there a simple way for me to add in some sort of blocking call after opening the window, to wait until we're ready to run this code?

我的问题是,有一种简单的方法让我在打开窗口后添加某种阻塞调用,等到我们准备好运行这段代码?

Thanks!

You can't really block until it's loaded but you can set an event in the popup, like this:

在加载之前你无法阻止,但你可以在弹出窗口中设置一个事件,如下所示:

myWindow.onload = function()
{
    document.title = pdfTitle;
    document.getElementById('pdfFrame').src = pdfLocation;
}
