1.获取屏幕宽度，并赋值给view
wx.getSystemInfo({
success: function (res) {
// console.log(res.windowWidth) 屏幕宽度
that.setData({
windowWidth: res.windowWidth
})
}
})
2.最近遇到自定义弹窗滚动问题，当文本页面过长，同时自定义弹窗也过长，即两者都需要滚动的时候，想要自定义弹窗滚动却触发的是页面的滚动。
解决思路：在打开弹窗的时候，让页面不可滚动；关闭弹窗后，恢复页面滚动。
<scroll-view scroll-y="{{isScroll}}">
<view class="rootView">
<view wx:for="{{arrayData}}" wx:key="" bindtap="showDialog" data-statu="open" class="inBoxVIew">
<text>{{item}}</text>
</view>
<!--测试弹窗-->
<view class="dialogbox" bindtap="showDialog" data-statu="close" wx:if="{{isDialogShow}}"></view>
<!--dialog-->
<view class="dialog" wx:if="{{isDialogShow}}">
<view class="windowTitle">
<text style="font-size:24px;">我是弹窗</text>
</view>
<view wx:for="{{dialogData}}" class="windowTable">
<text>{{item.name}}</text>
</view>
</view>
</view>
</scroll-view>
