JavaScript Implementation page no operation Countdown exit _javascript Tips

Project front-end page needs to be implemented, the page no one to operate into the countdown, the following is the front-end code implementation.

Set (Countdown function) switch
var _mouseactivelistener_flag = true;

Beforecount: Trigger countdown interval (in milliseconds)

Count: Countdown total (in seconds)

var mouseactivelistener = function (Beforecount, count, callback) {//config var __countdown_html = ' <div id= ' __tt ' s Tyle= "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 + ' seconds after exit ';
  _TC = settimeout (function () {Target_countdown (__count);
  }, 1000);
  else {callback ();
 } __count--; }, _t_exec = function () {return settimeout (function () {if (_mouseactivelistener_flag) {target = Ne.dom.createE
   L (__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 (); });

 };

After the operation, explained: After 5 seconds (5000) does not operate the state to trigger the countdown, the countdown 180 seconds, the concrete view code inside function.
Mouseactivelistener (5000, 180, function () {
 window.location.href = "/home/index";
 });
