Chrome扩展程序sendMessage从popup.html到content.js不起作用

Question

I'm trying to build an Extension which sends data from the popup.html to the tab dome, but I can't get the sendMessage to work and I don't understand why. 我正在尝试构建一个扩展程序，该程序将数据从popup.html发送到选项卡圆顶，但是我无法使sendMessage正常工作，我也不明白为什么。 I'm following this guidline: https://developer.chrome.com/extensions/messaging.html 我正在遵循以下准则： https : //developer.chrome.com/extensions/messaging.html

here are my sources: 这是我的资料来源：

manifest:
{
   "manifest_version": 2,
   "name": "OMG Campaign Preview Maker",
   "description": "Easy OMG Campaign Preview Maker",
   "background": {  "scripts": ["background.js"]},
   "version": "0.1",
   "content_scripts": [
        {
          "matches": ["http://*/*", "https://*/*"],
          "js": ["jquery-1.7.min.js", "content.js"]
        }
    ],
   "browser_action": {
      "default_icon": "logo_128.jpg",
      "popup": "popup.html",
      "default_popup": "popup.html"
   },
   "icons": {
      "128": "logo_128.jpg"
   }
}

popup.html popup.html

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="jquery-1.7.min.js"></script>
<script type="text/javascript" src="popup.js"></script>
</head>
<body>
<h1>Clicks</h1>
<p>extra1:
  <input type="text" name="extraclicks[]" id="extra1">
  <br>
  extra2:
  <input type="text" name="extraclicks[]" id="extra2">
  <br>
  extra3:
  <input type="text" name="extraclicks[]" id="extra3">
  <br>
  <br>
  <input type="submit" name="sendclicks" id="sendclicks" value="Invia Clicks">
</p>
</body>
</html>

popup.js popup.js

function sendClicks(){
    console.log("popup.js > sendClicks()");
    var clicksArr = new Array();

    $("input[name='extraclicks\\[\\]']").each(function(i, value){
        clicksArr.push($(this).val());
    });

    chrome.tabs.getSelected(null, function(tab) {
        console.log("popup.js > tab id: "+tab.id)
        chrome.tabs.sendMessage(tab.id, {type:"clicks" },
            function(response) {
                console.log(response.msg);
            }
        );
    });
    console.log("avra' inviato?");
}

$(function(){
    console.log("popup.js > OMD Extension ready");
    $('#sendclicks').click(function(){sendClicks();});
});

content.js content.js

chrome.extension.onMessage.addListener(function(request, sender, sendResponse) {
    console.log("content.js > onMessage");

    if (request.type == 'clicks') {
        console.log("content.js > clicks");
        sendResponse({msg: "success"});
    }
});

While I can perfectly see the logs gnerated from popup.js in the console, I don't see any of the logs launched by content.js. 虽然我可以在控制台中完美地看到从popup.js生成的日志，但看不到content.js启动的任何日志。 What am I doing wrong? 我究竟做错了什么？

Answer 1

oops, I think you just send message to popup.js itself... 糟糕，我想您只是将消息发送到popup.js本身...

getSelected in popup.js listen the activity of popup tab(it is a tab in chrome too) thus, the tab id is actually the popup tab, not the tab where your content.js are inserted popup.js中的getSelected侦听popup选项卡（也是chrome中的一个选项卡）的活动，因此，选项卡ID实际上是弹出式选项卡，而不是您的content.js插入的选项卡

BTW getSelected is deprecated. BTW getSelected已过时。 Try alternatives? 尝试替代方法？ http://developer.chrome.com/extensions/tabs.html#method-getCurrent http://developer.chrome.com/extensions/tabs.html#method-getCurrent

Answer 2

Ok, I'm stupid... the wrong thing was... the inspector page I was watching. 好吧，我很愚蠢……错误的事情是……我正在观看的检查器页面。 "console.log" inside of the content.js prints on the TAB INSPECTOR CONSOLE not on the extension one! content.js内部的“ console.log”打印在TAB INSPECTOR CONSOLE上，而不是扩展名上！

I hope it will help others. 我希望它会帮助其他人。
