// js 数组添加新属性和属性值

let person = _this.state.nearList;
    let newArr = person.map((item, index) => {
      return Object.assign(item, { distance: 100 })
    }, () => {
      _this.setNearList(newArr);
    })

// 匹配相同的属性值

    let person = this.state.roomList;
  console.log(  person.find(obj => obj.id == id)  )

//获取拥有相同属性值的序列号

    let idY= id
    let inIndex;
    $.each(person, function (index, value) {
      if (value.id == idY) {
        console.log(index);
        inIndex = index
        LeaseList.setIndexIn(inIndex)
      }
