简单的循环以及从接口获取数组对象的一个字段集合

1.简单的循环字段循环

  if (this.videolist) {console.log(111);for (let j = 0; j < this.videolist.length; j++) {if (this.videolist[j].video) {this.showVIdeo = false;return;} else {this.showVIdeo = true;}}} else {console.log(222);this.showVIdeo = true;}

2.使用循环从接口获取数组对象的一个字段集合

   let list= [];for (let j = 0; j < res.data.result.xxoptization.length; j++) {if(res.data.result.xxoptization[j].video){let temporaryItem = {};temporaryItem.video = res.data.result.xxoptization[j].video;temporaryItem.videoimg = res.data.result.xxoptization[j].videoimg;temporaryItem.videoname = res.data.result.xxoptization[j].videoname;temporaryItem.title = res.data.result.xxoptization[j].title;list.push(temporaryItem);}}this.videolist.push(...list);
