谷歌浏览器扩展：如何不止一次打开一个新的浏览器窗口？ [英] google chrome extension : how to open a new browser window more than once?

问题描述

我的Chrome扩展程序通过这个简单的JS打开一个新的浏览器窗口：

  chrome.browserAction.onClicked.addListener（function（ tab）{
 var room = new Date（）。getTime（）; 
 win = window.open（http://www.example.com/page.html#+ room，win ，width = 485，height = 55）; 
}）; 
  

这很好，但只有一次。

<第二次点击，它只是把焦点放在窗口上，但URL根本不会改变。

我也试过这个（没有成功）：

  win .location =http://www.example.com/page.html#\"+room; 
 win.location.reload（）; 
  

解决方案

window.open（） 是一个通用的JavaScript函数; Chrome的使用率限制了它，因此恶意网页无法产生许多窗口。

有一个窗口名称的概念， a href =https://developer.mozilla.org/en-US/docs/Web/API/Window/open =nofollow> window.open 。由于您重复使用同一个，因此不会打开新窗口。然而，作为扩展，您可以访问不受限制的工具。

也就是说，看看 chrome.windows 和 chrome.tabs APIs。

  chrome.windows.create（{url：fullyQualifiedURLHere}）; 
  

请注意 create / update 方法不需要特殊权限。

My Chrome extension opens a new browser window with this simple JS:

chrome.browserAction.onClicked.addListener(function(tab) {
  var room = new Date().getTime();
  win = window.open("http://www.example.com/page.html#"+room,"win","width=485,height=55");
});

This works great, but just once.

Second time I click, it just put the focus on the window but URL does not change at all.

I also tried this (with no success):

win.location = "http://www.example.com/page.html#"+room;
win.location.reload();  

解决方案

window.open() is a generic JavaScript function; Chrome rate-limits it so that malicious pages can't spawn many windows.

There is a concept of a "window name" with window.open. Since you're reusing the same one, it's not opening a new window. And the above rate-limiting still can apply.

However, as an extension, you have access to unrestricted tools.

Namely, take a look at chrome.windows and chrome.tabs APIs.

chrome.windows.create({url: "fullyQualifiedURLHere"});

Note that create/update methods do not require special permissions.
