您可以关注Chrome扩展程序中的弹出窗口吗？ [英] Can you focus a popup window from a Chrome Extension

问题描述

我有一个Chrome扩展程序，当单击扩展程序图标时，它会执行window.open（）。 （由于Chrome中存在无关的错误，因此无法使用传统的Chrome扩展程序弹出窗口）。我想知道如果有一种方法可以集中弹出窗口，如果它已经打开。 Chrome禁用了window.focus（），但我认为Chrome扩展中可能会有这样做。

I have a Chrome Extension that does a window.open() when the extensions icon is clicked. (It can't use the traditional Chrome extension popup due to an unrelated bug in Chrome). I'm wondering if there's a way to focus a popup window if its already open. Chrome disables window.focus() but I thought there might be a way to do it in a Chrome Extension.

更新：
对于任何感兴趣的人，这是我在后台页面中使用的代码：

Update: For anyone interested this is the code I ended up using in my background page:

var popupId;

// When the icon is clicked in Chrome
chrome.browserAction.onClicked.addListener(function(tab) {

  // If popupId is undefined then there isn't a popup currently open.
  if (typeof popupId === "undefined") {

    // Open the popup
    chrome.windows.create({
      "url": "index.html",
      "type": "popup",
      "focused": true,
      "width": 350,
      "height": 520
    }, function (popup) {
      popupId = popup.id;
    }); 

  } 
  // There's currently a popup open
  else {
     // Bring it to the front so the user can see it
    chrome.windows.update(popupId, { "focused": true });  
  }

});

// When a window is closed
chrome.windows.onRemoved.addListener(function(windowId) {
  // If the window getting closed is the popup we created
  if (windowId === popupId) {
    // Set popupId to undefined so we know the popups not open
    popupId = undefined;
  }
});

推荐答案

而不是使用window.open（）使用Chromes chrome.windows.create ... http://code.google.com /chrome/extensions/windows.html#method-create

...然后在回调中你可以记录它的window.id，然后任何时候你想让它聚焦，你可以使用chrome.windows.update。

Instead of using window.open() use the Chromes chrome.windows.create... http://code.google.com/chrome/extensions/windows.html#method-create
...then in the call back you can record its window.id and then any time you want to make it focused you can use chrome.windows.update.
