Question

我无法从后台脚本向内容脚本发送消息，除非我从manifest.json中的浏览器操作中删除了popup.html。有人帮我

background.js

// Called when the user clicks on the browser action.
chrome.browserAction.onClicked.addListener(function(tabs) {
  // Send a message to the active tab
  chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
    var activeTab = tabs[0];
    chrome.tabs.sendMessage(tabs[0].id, {"message": "clicked_browser_action"});
  });
});

// This block is new! and will be used later
chrome.runtime.onMessage.addListener(
  function(request, sender, sendResponse) {
    if( request.message === "open_new_tab" ) {
      chrome.tabs.create({"url": request.url});
    }
  }
);

content.js

chrome.runtime.onMessage.addListener(
  function(request, sender, sendResponse) {
    if( request.message == "clicked_browser_action" ) {
   console.log("Congratulations you can now work!");
     
      // This line is new!
      chrome.runtime.sendMessage({"message": "open_new_tab", "url": firstHref});
    }
  }
);

manifest.json

 {
    "name": "Wowprezi lead tool",
    "version": "1.0",
    "description": "Extension to find leads and add to sales force!",
	"author": "Djouonang Landry",
    "manifest_version": 2,
	
	 "content_security_policy": "script-src 'self' https://ssl.google-analytics.com; object-src 'self'",

   "background": {
   "persistent": true,
    "scripts": ["js/background.js"]
  },
  
   "content_scripts": [
        {
		    "matches": ["<all_urls>"],
		    "js": ["js/jquery-3.3.1.min.js","js/content.js"],
		    "all_frames": true
        }
    ],
	
  
  "browser_action": {
   "default_popup": "html/popup.html",
   "default_title": "Find leads"
 }
 
}

popup.html-除了从manifest.json中删除外，我无法将消息从后台发送到content.js。请注意，我使用控制台功能来检查消息是否已发送到content.js

Answer 1

根据documentation，chrome.browserAction.onClicked侦听器为

在单击浏览器操作图标时触发。 如果浏览器操作会弹出。

（已添加粗体）。

要么删除browserAction弹出窗口，要么将当前在侦听器中拥有的代码移动到弹出页面脚本。
