專案前端頁面需要實現,頁面沒人操作進入倒數計時,以下為前端程式碼實現。
//设置(倒计时功能)开关 var _mouseActiveListener_flag = true;
beforecount:觸發倒數間隔(單位:毫秒)
count:倒數總數(單位:秒)
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(); }); };
