仅在使用javascript和html的浏览器中切换相同的两个选项卡 [英] Switching between the same two tabs only in a browser using javascript and html
问题描述
我对要做什么的想法是
当我在Internet Explorer浏览器的一个选项卡上打开一个网站并单击一个链接时，它应该在具有pdf页面init的同一浏览器中打开一个新选项卡。 .. pdf页面有很多链接，如果你尝试点击它们中的任何一个，他们应该把你带回到那个你设法午餐打开pdf的旧标签，并且只在这两个标签之间切换
I希望这个想法很清楚..我试图用html和javascript来做到这一点...这是我写的，但我仍然在这里错过了很多。预先感谢您提供的任何帮助
My idea of what am trying to do is When I open a website on one tab of an internet explorer broweser and click on a link it should open a new tab in the same browser with a pdf page init ... the pdf page has a lot of links which if u try clicking on any of them they should take you back to the old tab where u managed to lunch open the pdf from and keep switching between those two tabs only I hope the idea is clear .. am trying to do this using html and javascript ... this what I wrote but am still missing a lot here. Thanks in advance for any help provided
这里的这一块在另一个窗口中另一个瞬间
this piece here lunches another instant in another window
<html>
<head>
<script>
function son()
{
myWindow=window.open('','','width=500,height=500');
myWindow.document.write(" SON !");
myWindow.focus();
myWindow.opener.document.write("<p> DAD !</p>");
}
</script>
</head>
<body>
<input type="button" value="Open " onclick="son()" />
</body>
</html>
这个文件是我内置pdf文件的地方。
This file is where I have the pdf file built in.
<object data="Test.pdf" type="application/pdf" width="100%" height="100%">
<p>It appears you don't have a PDF plugin for this browser.
you can <a href="Test.pdf">click here to
download the PDF file.</a></p>
</object>
再次感谢
thanks again
推荐答案
在过去，您可以使用窗口的 focus 方法将窗口/选项卡放到前景中。然而，滥用（主要以广告商的弹出窗口形式）导致浏览器限制或禁用该功能。
In the old days, you could use a window's focus method to bring a window/tab into the foreground. However, abuse (mostly in the form of advertisers' popup windows) has resulted in browsers restricting or disabling that functionality.
如果我们忽略PDF部分，从概念上讲，这是一个非常简单的要求。首先，打开一个窗口并保留其引用：
If we ignore the PDF part, conceptually, this is a very simple request. First, open a window and hold on to its reference:
var pop = window.open('page.html'); // opens in new tab on most browsers
在辅助页面中，切换回原来很简单：
In the secondary page, switching back to the original was simple:
window.opener.focus(); // no longer works in most modern browsers
然后从第一页开始切回： p>
And from the first page, to switch back:
pop.focus(); // might work
在我的测试，我无法让IE 9或Chrome 21切换回开启器选项卡。在Chrome中，我可以打开第二个页面，手动切换回原始选项卡，然后调用 pop.focus（）确实将第二个选项卡放回焦点。 （IE什么都没做）。我可以通过从辅助页面调用 window.opener.alert（'...'）; 来强制Chrome返回到开始页面，但这是一个丑陋的黑客。
In my test, I couldn't get IE 9 or Chrome 21 to switch back to the opener tab. In Chrome, I could open the second page, manually switch back to the original tab, and calling pop.focus() did bring the second tab back in focus. (IE did nothing.) I was able to force Chrome back to the opening page by calling window.opener.alert('...'); from the secondary page, but that's an ugly hack.
因此，看起来您无法将其取消，至少不可靠。
So it looks like you won't be able to pull this off, at least not reliably.
我不确定你想要完成什么（TOC？），但你有没有想过打开两个窗口？打开一个包含屏幕左侧的链接，另一半打开PDF。
I'm not sure exactly what you're trying to accomplish (a TOC?), but have you thought about opening two windows? Open one with your links that covers the left-hand side of the screen, and another on the other half with the PDF.
