下面的这个放到 Vue data里面的return里面去 ------------- 也就是》》》》data（）{return{}}
animate: false,
marqueeList: [
{
name: '1军电视剧烦恼是的空间开发'
},
{
name: '2军水电费了羧甲淀粉钠盛开'
},
{
name: '3军第三方库收到货否'
},
{
name: '4军杜师傅iOS'
}
],
接着在created：function里面放入这个
setInterval(this.showMarquee, 2000)
最后一步就是，放到，方法里面也就是，methods，里面下面就是要放的
showMarquee: function () {
this.animate = true;
setTimeout(()=>{
this.marqueeList.push(this.marqueeList[0]);
this.marqueeList.shift();
this.animate = false;
},500)},
