數組的模糊查詢

對數組的基本模糊查詢

定義數組

mallList: [
      {
        id: 1,
        img: 'https://tse2-mm.cn.bing.net/th/id/OIP.B5xAajd2dWNwJn2Q7IY-IQHaEK',
        title: '霍尼韋爾H910Plus系列KN95防霧系列KN95防霧系列KN95防霧霾口罩',
        money: 105,
        num: 550
      },
      {
        id: 2,
        img: 'https://tse2-mm.cn.bing.net/th/id/OIP.B5xAajd2dWNwJn2Q7IY-IQHaEK',
        title: '家用洗臉毛巾',
        money: 110,
        num: 1000
      },
      {
        id: 3,
        img: 'https://tse2-mm.cn.bing.net/th/id/OIP.B5xAajd2dWNwJn2Q7IY-IQHaEK',
        title: '小霸王牌多功能電飯鍋',
        money: 15,
        num: 700
      },
      {
        id: 4,
        img: 'https://tse2-mm.cn.bing.net/th/id/OIP.B5xAajd2dWNwJn2Q7IY-IQHaEK',
        title: '自助飲食',
        money: 99,
        num: 680
      }
    ],

創建方法，並進行模糊查詢

  onDropItem() {
    var mallList = this.data.mallList
    mallList = mallList.filter(function (t) {
      return t.title.search('飲食') > -1  //search()或者indexOf()
    })
    this.setData({
      mallList: mallList
    })
  },
