动态设置WX滚动条的高度（非常重要）

wxml:

<scroll-view class="scroll" scroll-y="true" style="height:{{clientHeight?clientHeight+'px':'auto'}}">

js:

onShow: function (options) {

 

wx.setNavigationBarTitle({

title: options.title

});

var that = this;//用在wx的API中要用that不能用this

wx.getSystemInfo({

success: function (res) {

var height = res.windowHeight-46;//1rpx=0.5px

console.log(height);

that.setData({

clientHeight: height

})

}

});

 

},
