wxml:

<form bindsubmit="formSubmit">

<view class="weui-cell weui-cell_input ">

<view class="weui-cell__hd">

<view class="weui-label"><span class='required-color'>*</span>名字</view>

<view class="weui-cell__bd panel-case">

<view class="picker">{{caseArray[caseIndex].reason_name}}</view>

</picker>

</view>
