Chrome扩展程序 - 在新标签页中打开捕获的屏幕截图 [英] Chrome extension-Open the captured screen shot in new tab

问题描述

chrome.tabs.query({
    active: true, 
    currentWindow: true 
    },
    function (tabs) {
    chrome.tabs.captureVisibleTab(null 
        ,{ format: "png"},
        function (src) {
            $('body').append("<img src='" + src + "'>" + tabs[0].url + "</img>");//appends captured image to the popup.html
        }
    ); 
}); 

此代码将捕获的图像附加到popup.html的主体中。但我想要的是将图像附加到弹出体上，我想用chrome.tabs.create（{url：newtab.html）打开新标签，并将捕获的图像追加到这个newtab.html中。 'newtab.html'已经在路径文件夹中）。

This code appends the captured image into the body of popup.html. But what I want is insted of appending the image to the popup body i would like to open new tab using chrome.tabs.create({url:"newtab.html") and append the captured image to this newtab.html.(the 'newtab.html' is already in the path folder).

预先感谢

Thanks in advance

推荐答案

我之前介绍过的一种方法是此处。

There is a way I described previosuly here.

要点是打开包含脚本的选项卡，并使用消息传递与它进行通信。

The gist is to open a tab that contains a script, and the communicate with it using messaging.

出现的一个小问题是，您不知道新打开的页面何时准备就绪。我解决了这个问题，让新打开的页面独立地与后台页面联系，但只是有一个全局变量而sl <。

A little problem that arises is that you don't know when the newly-opened page is ready. I solved that by making the newly-opened page contact the background page on its own, but was sloppy with just having one global variable.

更好的解决方案是一个-shot事件监听器，就像这样：

A better solution would be a one-shot event listener, something like that:

// Execute this code from the background page, not the popup!
function openScreenshot(src){
  chrome.tabs.create(
    { url: chrome.runtime.getURL("newtab.html") },
    function(tab) {
      chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) {
        // If the request is expected and comes from the tab we just opened
        if(message.getScreenshot && sender.tab.id == tab.id) {
          sendResponse(src);
          // Ensure we're only run once
          chrome.runtime.onMessage.removeListener(arguments.callee);
        }
      });
    }
  );
}
