Chrome扩展程序中的数据未从弹出窗口传递到后台

Question

I think I got the hang of it but it's just not working... and I can't figure out why. 我想我掌握了这个要诀，但是它没有用……我不知道为什么。

Manifest: 表现：

{
  "name": "Dummy Extension",
  "description": "Dummy Extension Description",
  "version": "2.0",
  "permissions": [
    "activeTab"
  ],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  },
  "browser_action": {
    "default_title": "Dummy Extension",
     "default_popup": "popup.html"
  },
  "manifest_version": 2,
  "content_scripts": [ {
    "js": [ "jquery.min.js", "background.js" ],
    "matches": [ "http://*/*", "https://*/*"]
  }]
}

Background: 背景：

chrome.extension.onMessage.addListener( function(request,sender,sendResponse)
{
    if( request.greeting === "GetURL" )
    {
        var tabURL = "Not set yet";
        chrome.tabs.query({active:true},function(tabs){
            if(tabs.length === 0) {
                sendResponse({});
                return;
            }
            tabURL = tabs[0].url;
            sendResponse( {navURL:tabURL} );
        });        
    }
}

Popup.html Popup.html

<!DOCTYPE html>
<head>
<script src='popup.js'></script>
<script src='jquery.min.js'></script>
</head>
<body>
    Hello World!
        <br />
    <input id="tabURL" type="text" />
        <br />
    <input value="SEND!" type="button" id="send" />
</body>
</html>

And popup.js 还有popup.js

function getURL() {
    chrome.extension.sendMessage({greeting: "GetURL"},
        function (response) {
            tabURL = response.navURL;
            $("#tabURL").val(tabURL);
        });
}

$("#send").click(getURL());

I just can't figure out whats wrong, jquery is defined, I get no console errors. 我只是不知道出了什么问题，定义了jquery，没有控制台错误。 Any help would be great! 任何帮助将是巨大的！

Answer 1

$("#send").click(getURL()); gets executed before DOM is fully constructed and fails. 在完全构建DOM并失败之前执行。 Also, you need to pass the reference to getURL , not execute it. 另外，您需要将引用传递给getURL ，而不是执行它。

To fix: 修理：

$(document).ready(function(){
  $("#send").click(getURL);
});

By the way, you may be looking in the wrong console for errors. 顺便说一句，您可能正在错误的控制台中查找错误。 See this debugging tutorial for popups. 有关弹出窗口，请参见此调试教程。
