我正在编写我的第一个chrome扩展，我在这个领域有点新。

我的目标是将 url 和电子邮件发送到 PHP 服务器，但现在我将它们发送到控制台。

我的

问题是保存用户输入到我的分机的最后一封电子邮件。现在，当我关闭浏览器时，电子邮件的值将更改为未定义。

我放了扩展的整个代码，但我认为问题一定出在getemail函数上。

背景.js

//variables defenitions:
var email;
var urll;
//functions:
function getemail(){
     email = window.prompt("Pleas  enter your Email address:");
     chrome.storage.sync.set({'email':email}, function() {
      alert('You entered 'n[' + email + "]'n as Email address.'nThank you for registration." );
      });
        var id = chrome.contextMenus.create({"title": "Submit your url","onclick":consollog });
        var id = chrome.contextMenus.create({"title": email+"/Change" ,"onclick":getemail });
        chrome.contextMenus.remove("1", null);
        chrome.contextMenus.remove("2", null);
        var id = chrome.contextMenus.create({"id":"2","title": "SUPPORT","onclick":support});
     }

function create(){
        var id = chrome.contextMenus.create({"title": "Submit your url","onclick":consollog });
        var id = chrome.contextMenus.create({"title": email+"/Change" ,"onclick":getemail });
        chrome.contextMenus.remove("1", null);
        chrome.contextMenus.remove("2", null);
        var id = chrome.contextMenus.create({"id":"2","title": "SUPPORT","onclick":support});
     }
function support(){
    alert("Contact ways:'nPhone number:+989378114692'nEmail address:amukiarash@gmail.com");
  }
function consollog(info, tab) {
  chrome.tabs.query({
  'active':true,"currentWindow": true,
}, function(lTabs) {
    urll=lTabs[0].url;
  console.log(urll)
  console.log(email)
  alert('You sent "' + urll + '" to our server');
});
}
//menu items:
if(email==undefined){
   var id = chrome.contextMenus.create({"id":"1","title": "Register Email","onclick":getemail });
    } 
   else {create();}

var id = chrome.contextMenus.create({"id":"2","title": "SUPPORT","onclick":support});

manifest.json：

{
   "name": "Jenco",
   "description": "This extension helps you to send url",
   "version": "0.9",
   "browser_action":{
      "default_icon":"32.png",
      "default_popup":"mypopup.html"},
   "permissions": ["contextMenus","tabs","activeTab", "http://*/*", "https://*/*","storage"],
   "background": {
      "scripts": ["background.js"]
      },
   "manifest_version": 2,
   "icons": { "16": "16.png",
              "32": "32.png",
              "48": "48.png" },
   "commands": {
      "send-url": {
         "suggested_key": { "default": "Ctrl+Shift+Z" },
         "description": "Send an url"
                    }
                }
}

保存变量和加载变量的代码：

// Saving
chrome.storage.sync.set({"variableName": value});
// Loading 1 thing
chrome.storage.sync.get("variableName", function(result){
    // Showing the requested variable value
    alert(result.variableName);
});
// Loading more things
chrome.storage.sync.get(["variableName", "variableNameTheSecond"], function(result){
    // Showing first the first one and then the second one
    alert(result.variablename);
    alert(result.variableNameTheSecond);
});

我希望这对你有帮助，问候
