JavaScript实现页面无操作倒计时退出

//设置（倒计时功能）开关var _mouseActiveListener_flag = true;

var mouseActiveListener = function (beforecount, count, callback) { //configvar __countdown_html = '<div id="__tt" style="position:fixed;top:110px;right:10px;z-index:1000;color:#eee;font-size:25px;"></div>'; //define var target = null, _t = null, _tc = null;var target_countdown = function (__count) {  if (__count >= 0) {  target.innerHTML = __count + '秒后退出';  _tc = setTimeout(function () {   target_countdown(__count);  }, 1000);  } else {  callback();  }  __count--; }, _t_exec = function () {  return setTimeout(function () {  if (_mouseActiveListener_flag) {   target = Ne.dom.createEl(__countdown_html);   document.body.appendChild(target);   target_countdown(count);  }  }, beforecount); }, _t_clear = function () {  clearTimeout(_t);  clearTimeout(_tc);  //target.parentElement.removeChild(target);  $(target).remove();  target = null; }; //exec _t = _t_exec(); document.addEventListener('click', function () {  _t_clear();  _t = _t_exec(); }); };

//后置操作，解释：在5秒后（5000）不操作的状态下触发倒计时，倒计时180秒，具体看View Code里面的函数。mouseActiveListener(5000, 180, function () { window.location.href = "/Home/Index"; });
