Vue中foreach数组与js中遍历数组的写法说明

//定义班次详细数组
  var bcglxiangxiList = new Array();
  //定义班次详细对象
  var bcxiangxi  = {};
  //循环传递的参数
  bcglXiangXiListParam.forEach(element => {
    bcxiangxi.xh = element.xh;
    bcxiangxi.bcbh = data.bcbh;
    bcxiangxi.dkkssj = element.sjfw[0];
    bcxiangxi.dkjssj = element.sjfw[1];
    bcxiangxi.ts = element.ts;
    bcxiangxi.dkdd = element.dkdd;
    bcxiangxi.zxjxljsj = element.jxsjfw[0];
    bcxiangxi.zdjxljsj = element.jxsjfw[1];
    //将班次详细对象存进班次详细数组
    bcglxiangxiList.push(bcxiangxi);
  });

 var bcglxiangxiList = new Array();
        var bcxiangxi = {};
        debugger;
