由于官方API提供的显示模态弹窗，只能简单地显示文字内容，不能对对话框内容进行自定义，欠缺灵活性，所以自己从模态弹窗的原理角度来实现了自定义的模态对话框。
<!--index.wxml-->
<button class="show-btn" bindtap="showDialogBtn">弹窗</button>
<!--弹窗-->
<view class="modal-mask" bindtap="hideModal" catchtouchmove="preventTouchMove" wx:if="{{showModal}}"></view>
<view class="modal-dialog" wx:if="{{showModal}}">
<view class="modal-title">添加数量</view>
<view class="modal-content">
<view class="modal-input">
<input placeholder-class="input-holder" type="number" maxlength="10" bindinput="inputChange" class="input" placeholder="请输入数量"></input>
