一般项目里,有的会在启动的时候加开屏广告或者闪屏广告。我们是在index.html通过定位来做的。如下:
然后我们需要单独写一份js文件,跟main.js是同级目录的,具体代码如下:
修改开屏广告图片尺寸
let advWidth = document.documentElement.clientWidth;
let advHeight = document.documentElement.clientHeight;
let entryEl = document.getElementById('entry');
entryEl.style.widht = advWidth + 'px';
entryEl.style.height = advHeight + 'px';
let queryURL = window.location.href.split('?')[1];
// 判断是否为分享页面
if (queryURL) {
let queryArr = queryURL.split('&');
let query = {};
for (let i = 0; i < queryArr.length; i++) {
query[queryArr[i].split('=')[0]] = queryArr[i].split('=')[1]
}
if (Number(query.showTitle)) {
// 分享页面中 H5入口(我们项目中做了分享功能,若是从原生APP分享进入H5页面的,也需要加开屏广告)
api.commonApi('后台接口','传参数')
.then(res => {
let keyArr = [];
for (let key in res.data) {
keyArr.push(key);
}
if (keyArr.length == 0) {
return;
}
openAdv(res);
});
} else {
// 分享页面中 原生入口
// 查看query中是否带有token,进行登录判断并将token存入vuex
if (query.TOKEN != '' && query.TOKEN != 'null') {
store.dispatch('storeToken',query.TOKEN);
}
}
} else {
// 不是分享页面的入口
api.commonApi('后台接口','传参数')
.then(res => {
let keyArr = []
for (let key in res.data) {
keyArr.push(key);
}
if (keyArr.length == 0) {
return;
}
openAdv(res);
});
}
function openAdv(res) {
entryAdv.style.display = 'block';
document.body.style.overflowY = 'hidden';
// 阻止滑动执行
document.body.ontouchmove = function(ev) {
ev.preventDefault();
};
let list = res.data.retList;
if (list && list.length == 0) {
entryAdv.style.display = 'none';
document.body.style.overflow = 'auto';
document.body.ontouchmove = function(ev) {
ev.stopPropagation();
};
}
let time = (res.data.SPJG || 5000) / 1000;
// let time = res.data.SPJG;
let ADV_list = [];
let BCcontextPathSrc = store.state.common.BCcontextPathSrc;
switch (res.data.ADV_TYPE) {
// 开屏直接跳过
case '1':
{
let ImgList = [];
for (let i = 0; i < list.length; i++) {
ImgList.push(BCcontextPathSrc + res.data.retList[i].ADV_IMG_URL);
ADV_list.push(res.data.retList[i].ADV_URL);
}
let count_down = time / list.length;
let ImgNum = 0;
let timer = setInterval(() => {
switch (ImgList.length) {
case 1:
break;
case 2:
{
if (time % 3 == 0) {
ImgNum++;
}
}
break;
case 3:
{
if (time % 2 == 0) {
ImgNum++;
}
}
break;
case 4:
{
if (time % 1 == 0) {
if (ImgNum > ImgList.length - 2) break;
ImgNum++;
}
}
break;
default:
{
if (time % 1 == 0) {
if (ImgNum > ImgList.length - 2) break;
ImgNum++;
}
}
break;
}
if (time <= 0) {
clearInterval(timer);
entryAdv.style.display = 'none';
document.body.style.overflowY = 'auto';
document.body.ontouchmove = function(ev) {
ev.stopPropagation();
};
}
entry.src = ImgList[ImgNum];
entryTim.innerHTML = '跳过 ' + time + 's';
entry.addEventListener('click',function() {
window.location.href = ADV_list[ImgNum];
},false);
time--;
},1000);
entryTim.addEventListener('click',function(ev) {
ev.preventDefault();
clearInterval(timer);
entryAdv.style.display = 'none';
document.body.style.overflowY = 'auto';
document.body.ontouchmove = function(ev) {
ev.stopPropagation();
};
},false);
}
break;
// 闪屏广告
case '2':
同上开屏广告,可根据贵公司要求来更改
}
};
setTimeout(() => {
require('./main.js');
},300)
这样就完成了。
