The front-end page of the project needs to be implemented. If no one operates the page, it will enter the countdown. The following is the front-end code implementation.
//设置(倒计时功能)开关 var _mouseActiveListener_flag = true;
beforecount: Trigger countdown interval (unit: milliseconds)
count: Total countdown (unit: seconds)
var mouseActiveListener = function (beforecount, count, callback) { //config var __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"; });
