Question

我尝试了几种方法来实现这一目标，包括添加permissions。这是我的Manifest.json：

    {
  "manifest_version": 2,
  "name": "name",
  "version": "0.8",
  "permissions": [
  "http://example.com/",
  "https://example.com/"
],
   "content_scripts": [
    {
      "matches": [
        "<all_urls>"
      ],
      "js": ["jquery.min.js", "content.js"],
      "run_at": "document_end"
    }
  ],
  "background": {

    "page": "background.html"
  },
  "browser_action": {
    "default_icon": "icon.png",
     "default_popup" : "Popup.html"
  },
  "permissions": [
    "tabs"
],
"content_security_policy": "script-src 'self' https://ssl.google-analytics.com; object-src 'self'"
}

popup.js：

/**
 * Get the current URL.
 *
 * @param {function(string)} callback - called when the URL of the current tab
 *   is found.
 */
function getCurrentTabUrl(callback) {
  // Query filter to be passed to chrome.tabs.query - see
  // https://developer.chrome.com/extensions/tabs#method-query
  var queryInfo = {
    active: true,
    currentWindow: true
  };

  chrome.tabs.query(queryInfo, function(tabs) {
    // chrome.tabs.query invokes the callback with a list of tabs that match the
    // query. When the popup is opened, there is certainly a window and at least
    // one tab, so we can safely assume that |tabs| is a non-empty array.
    // A window can only have one active tab at a time, so the array consists of
    // exactly one tab.
     tab = tabs[0];

    // A tab is a plain object that provides information about the tab.
    // See https://developer.chrome.com/extensions/tabs#type-Tab
     url = tab.url;
     fixedURL = url;
     fixedURL = url.substring(1);



    // Open the page up.

    // tab.url is only available if the "activeTab" permission is declared.
    // If you want to see the URL of other tabs (e.g. after removing active:true
    // from |queryInfo|), then the "tabs" permission is required to see their
    // "url" properties.
    //console.assert(typeof url == 'string', 'tab.url should be a string');

    callback(url);
  });

  // Most methods of the Chrome extension APIs are asynchronous. This means that
  // you CANNOT do something like this:
  //
  // var url;
  // chrome.tabs.query(queryInfo, function(tabs) {
  //   url = tabs[0].url;
  // });
  // alert(url); // Shows "undefined", because chrome.tabs.query is async.
}

/**
 * @param {string} searchTerm - Search term for Google Image search.
 * @param {function(string,number,number)} callback - Called when an image has
 *   been found. The callback gets the URL, width and height of the image.
 * @param {function(string)} errorCallback - Called when the image is not found.
 *   The callback gets a string that describes the failure reason.

function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("main").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","http://localhost:8000/extension/?url="+fixedURL,true);
xmlhttp.send();
}


document.addEventListener('DOMContentLoaded', function() {
  getCurrentTabUrl(function(url) {

loadXMLDoc();




//console.log(url);


    }, function(errorMessage) {

    });
  });

点击扩展程序后得到的答案的相关部分：

  $(document).ready(function(){
    $("#scannedinfo").click(function(event){
      event.preventDefault();
      email = $('#scannedinfo-email').val();
      emailval = validateEmail(email);
      if(emailval != false){
        $('.scannedinfo-error').text('');
        $.get("https://example.com/ajaxpage",
        {
          email: $('#scannedinfo-email').val(),
          message: $('textarea').val()
        },
        function(data,status){
          //do stuff
            }
        });
      } else{
        //do stuff
      }

    });
  });

当我打开我在浏览器中进行AJAX调用的URL时，它工作正常。当我检查扩展时似乎没有发生任何事情。没有错误或任何东西。问题可能是什么？有什么想法吗？
