js代码
Page({ /** * 页面的初始数据 */ data: { showIndex:null,//打开弹窗的对应下标 height:'',//屏幕高度 }, // 打开弹窗 openPopup(e){ var index = e.currentTarget.dataset.index; this.setData({ showIndex:index }) }, //关闭弹窗 closePopup(){ this.setData({ showIndex:null }) }, /** * 生命周期函数--监听页面初次渲染完成 */ onReady() { var that = this; // 动态获取屏幕高度 wx.getSystemInfo({ success: (result) => { that.setData({ height: result.windowHeight }); }, }) }, })
代码简洁,类型齐全。本人才疏学浅,代码仅供参考,如有问题,请多多指教,酸Q。
