wxss部分

.container {
  height: 100%;
  display: flex;
  flex-direction: column;
  align-items: center;

js部分????

page上方添加????
var x,y,x1,y1,x2,y2,index,currindex,n,yy;
var arr1 = [{ content:11,id:1 },{ content:22,id:2 },{ content:33,id:3 },{ content:44,id:4 },{ content:55,id:5 }] //这里初始化的时候替换自己要更改的数组

data中空数组变量????
page(
　　data:{
　　　　mainx:0,
　　　　content:[{ content:11,id:1 },{ content:22,id:2 },{ content:33,id:3 },{ content:44,id:4 },{ content:55,id:5 }], //这里初始化的时候替换自己要更改的数组
　　　　start:{x:0,y:0}
　　}

)
