取高度值

onLoad:function(){
     var that = this;
    //  这里要非常注意，微信的scroll-view必须要设置高度才能监听滚动事件，所以，需要在页面的onLoad事件中给scroll-view的高度赋值
    wx.getSystemInfo({
    success: function(res) {
      console.log(res.model)
      console.log(res.pixelRatio)
      console.log(res.windowWidth)
      console.log(res.windowHeight)
      that.setData({
          windowH:res.windowHeight-44
        });
      console.log(res.language)
      console.log(res.version)
      console.log(res.platform)
    }
    })
 },
