Page({
  data: {
    list:[
      { id: 1, name: '美食', choosed: false, },
      { id: 2, name: '运动健身', choosed: false, },
      { id: 3, name: '旅行', choosed: false, },
    ]
  },
 itemSelected(e){
    let index = e.target.dataset.index
    let temp_str = 'list['+index+'].choosed';
    console.log();
    this.setData({
      [temp_str]: !this.data.list[index].choosed
    });
    console.log(this.data.list)
  },
})
