$(()=> { let param = { tag: true, num: 1, ele: document.createElement('div'), icon: '&#xe6a2;', homeIcon: '&#xe643;', moreIcon: '&#xe627;', personalIcon: '&#xe644;', closeIcon: '&#xe628;', distance: '500', css: "position:fixed;" + "bottom:4rem;" + "box-shadow:10px 10px 10px gray;" + "right:10px;" + "display:none;" + "font-size:1.5rem;" + "color:#fff;" + "z-index:1000;" + "height:2.5rem;" + "width:2.5rem;" + "background:#f44336;" + "border-radius:50%;" + "line-height:2.5rem;" + "text-align:center", menuCss: "position:absolute;" + // "bottom:3rem;" + "display:none;" + "box-shadow:10px 10px 10px gray;" + "font-size:1.2rem;" + "color:#fff;" + "background:orange;" + "height:2rem;" + "width:2rem;" + "border-radius:50%;" + "text-align:center;" + "line-height:2rem;" // type: '#top' }; { document.querySelector('body').appendChild(((ele)=> { ele.className = 'scroll iconfont'; ele.innerHTML = param.moreIcon; // ele.href = param.type; ele.style.cssText = param.css; for (let i = 0; i < 3; i++) { let menu_personal = document.createElement('a'); menu_personal.className = 'iconfont'; menu_personal.style.cssText = param.menuCss; switch (i) { case 0: setStyle(menu_personal, '#2196f3', '2.4rem', '2.4rem', param.homeIcon, 'home'); break; case 1: setStyle(menu_personal, '#4caf50', 0, '3.5rem', param.personalIcon, 'personal'); break; case 2: setStyle(menu_personal, '#fdd835', '3.5rem', '0', param.icon, 'top'); break; } param.ele.appendChild(menu_personal); } return ele; })(param.ele)); function setStyle(ele, ...args) { ele.style.background = args[0]; ele.style.bottom = args[1]; ele.style.right = args[2]; ele.innerHTML = args[3]; ele.id = args[4]; } } { $(window).scroll(()=> { var scrollValue = $(window).scrollTop(); if (scrollValue > param.distance) { if (param.tag) { $(param.ele).css('display', 'block').animateCss('fadeInRight'); param.tag = !param.tag; } } else { if (!param.tag) { $(param.ele).css('display', 'none'); $(param.ele).children().css('display', 'none'); param.num++; param.tag = !param.tag; } } }); $(param.ele).click((e)=> { window.e = e; switch (e.target.id) { case 'home': if (!getTypeNative()) { window.location.href = getAbsolutePath() + '/fenqihui/pages/recommended/recommended_index.html'; } else if (getTypeNative() === 'ios') { backHome(); } else if (getTypeNative() === 'android') { android.backHome(); } break; case 'personal': if (!getTypeNative()) { window.location.href = getAbsolutePath() + '/fenqihui/pages/account/user_personal.html'; } else if (getTypeNative() === 'ios') { //todo://前往个人中心 backAccount(); } else if (getTypeNative() === 'android') { android.backAccount(); } break; case 'top': $(window).scrollTop(0); break; } param.num % 2 == 0 && $(param.ele).children().css('display', 'none') || $(param.ele).children().css('display', 'block').animateCss('swing'); param.num++; }) } });
