 数组对象排序

this.compare = function(prop) {
          return function(obj1, obj2) {
            let val1 = obj1[prop]
            let val2 = obj2[prop]
            if (!isNaN(Number(val1)) && !isNaN(Number(val2))) {
              val1 = Number(val1)
              val2 = Number(val2)
            }
            if (val1 < val2) {
              return -1
            } else if (val1 > val2) {
              return 1
            } else {
              return 0
            }
          }
        }
        const target = arr.sort(this.compare('id'))
