Question

我开发了chrome（后台插件）插件。但是，我认为我有内存泄漏。你可以帮帮我吗？当我使用chrome profiler时，我可以看到

compare memory
In the beginning

"use strict";

var URL = 'https://api.mysite.org/messages';

var ajax;
var intervalId;
var notification;

function onInterval() {
  updateData();
}

function updateData() {
  if (intervalId) {
    window.clearTimeout(intervalId);
  }

  if (ajax) {
    ajax.abort();
    ajax = null;
  }

  intervalId = window.setTimeout(onInterval, 1000 * 60);
  executeAjax();
}

function executeAjax() {
  ajax = $.ajax({
    type: 'GET',
    timeout: 1000 * 10,
    dataType: 'json',
    url: URL,
    cache: false
  });
  ajax.done(done);
  ajax.fail(error);
}

function done(rawData) {
  var tmp = rawData.messages;
  if (tmp != null) {
            notify(tmp);
  }
}

function notify(icon, newStatus, message) {
  var options = {
    title : 'New Message',
    priority : 0,
    iconUrl : 'icon/notif.png'
  };
  options.type = 'basic';
  options.message = message;
  chrome.notifications.create('', options);
}

$(document).ready(onInterval);

错误暂时是一个空函数

javascript对象内存泄漏
