微信小程序之全選與反選(點擊某項數據時，再次點擊，則勾選全部(改變了全選按鈕只點擊兩次的可見效果))

 

 //單選
  select: function(e) {
    var that = this;
    var index = e.currentTarget.dataset.index; //獲取當前點擊的下標
    var navbarActiveIndex = that.data.navbarActiveIndex;//操作的房間下標
    var homeList = wx.getStorageSync('homeList');//緩存數據(家庭)
    var nowText = wx.getStorageSync('nowText');//當前操作對象
    var checkboxArr = that.data.broadcast;//頁面當前數據項
    checkboxArr[index].checked = !checkboxArr[index].checked;//設備選中狀態
    var e, globalEquipment;
　　 //定位所操作的數據項
    homeList.map((h, hIndex) => {
      if (h.homeId == nowText) {
        e = h;
      }
    })
　　　//定位其房間
    e.roomNameAll.map((r, rIndex) => {
      if (navbarActiveIndex == rIndex) {
        globalEquipment = r;
      }
    })
    if (checkboxArr[index].checked) {
      globalEquipment.equimentDatalist.map((g, gIndex) => {
        if (g.srcAddr == checkboxArr[index].srcAddr && g.channel == checkboxArr[index].channel) {
          g.checked = true;
          globalEquipment.selectCount = globalEquipment.selectCount + 1;
        }
      })
    } else {
      globalEquipment.equimentDatalist.map((g, gIndex) => {
        if (g.srcAddr == checkboxArr[index].srcAddr && g.channel == checkboxArr[index].channel) {
          g.checked = false;
          globalEquipment.selectCount = globalEquipment.selectCount - 1;
        }
      })
    }
    if (globalEquipment.selectCount == globalEquipment.equimentDatalist.length) {
      globalEquipment.selectilall = true;
      globalEquipment.selectCount = globalEquipment.equimentDatalist.length;
      that.setData({
        navbarTitle: e.roomNameAll,
        broadcast: globalEquipment.equimentDatalist
      })
    } else {
      if (globalEquipment.selectilall == true) {
        globalEquipment.selectilall = false;
        that.setData({
          navbarTitle: e.roomNameAll
        })
      }
      that.setData({
        broadcast: globalEquipment.equimentDatalist
      })
    }
    wx.setStorageSync('homeList', homeList);
  },
  //全選與反選
  selectAll: function(e) {
    var that = this;
    var navbarActiveIndex = that.data.navbarActiveIndex;
    var homeList = wx.getStorageSync('homeList');
    var nowText = wx.getStorageSync('nowText');
    let selectilall = this.data.selectilall;
    var state = e.currentTarget.dataset.states;
    var e, globalEquiment;
    homeList.map((ee, eIndex) => {
      if (ee.homeId == nowText) {
        e = ee;
      }
    })
    e.roomNameAll.map((r, rIndex) => {
      if (navbarActiveIndex == rIndex) {
        globalEquiment = r;
      }
    })
    if (globalEquiment.selectCount < globalEquiment.equimentDatalist.length && globalEquiment.selectilall == false) {
      globalEquiment.selectilall = true;
      globalEquiment.equimentDatalist.map((g, gIndex) => {
        g.checked = true;
      })
      globalEquiment.selectCount = globalEquiment.equimentDatalist.length;
    } else {
      globalEquiment.selectilall = false;
      globalEquiment.equimentDatalist.map((g, gIndex) => {
        g.checked = false;
      })
      globalEquiment.selectCount = 0;
    }
    that.setData({
      navbarTitle: e.roomNameAll,
      broadcast: globalEquiment.equimentDatalist
    });
    wx.setStorageSync('homeList', homeList);

  },

前端頁面屬於商業機密，這里就不顯示啦。暖陽下，我迎芬芳。
