如何将已打开的浏览器窗口置于顶部。 [英] How to bring already open browser window on top.

问题描述

我有一个软件，当我点击打印按钮时，会打开一个PDF格式的新窗口进行打印。



现在真正的问题是，我不关闭那个窗口，它在后台保持打开状态。因此，当我单击新打印按钮时，背景中的PDF会更新并保留在后台。



我想要的是每当我点击打印按钮时，

1）如果窗口未打开，则会显示打开和打印页面。

2）如果窗口已经打开，它会弹出并堆叠在我的屏幕上。



如果有任何进一步的问题请问我。

I am having a software in which when I click on print button, a new window opens up in PDF format for printing.

Now the real question is, I dont close that window & it stays open in background. Thus when I click on new print button, the PDF in background gets updated & stays in background.

What I wants is that whenever I click on print button,
1) If window not open, opens up & print page is displayed.
2) If window already open, it pops up & is stacked on top of my screen.

If any further question do ask me.

推荐答案

这不是一个好主意，有点过于干扰。我建议使用一种替代方法，单页面应用程序方法：

不仅对用户不那么恼火并提供更好的用户体验，它还会为您省去很多麻烦。例如，您说：在这种情况下，将此窗口置于顶部。但你永远不知道，它是一个真正的浏览器窗口，还是只是其中一个标签。标签和单独窗口之间的选择完全取决于用户;和Web标准几乎忽略了差异，但浏览器实现的功能差异是显而易见的。当您处理单个页面时，您可以控制所有内容。您计划在不同的窗口中创建一个单独的，例如， div 在同一页面上，例如，可以停靠，取消停靠，隐藏或显示...

This is not a very good idea, a bit too intrusive. I would suggest using one alternative, the single-page application approach:
Single-page application - Wikipedia, the free encyclopedia[^].

Not only it would be not so irritating to the users and provide much better user experience, it will also save you from a lot of trouble. For example, you say: on this condition, put this window on top. But you never know, is it a real browser window, or just one of the tabs. The choice between tabs and separate windows is totally on the users; and Web standards pretty much ignore the difference, but the functional difference implemented by the browsers is apparent. When you work on a single page, you have everything under control. What you planned to make a different window will be just a separate, say, div on the same page, which can be, for example, docked, undocked, get hidden or shown…
