微信小程序 - 表单验证插件WxValidate（自定义警告信息形式）

弹出的形式对于用户来说，总是不太友好的

可能会出现层级问题（只需要设置一下提示的层级即可）

WxValidate内置规则

以下代码拷贝即可使用~

wxml

<form bindsubmit='submitCheckInfo'>

<!-- 提示警告! -->
<view class='wran-tips' style='{{displayWarn}}'>
<text>{{warnInfo}}</text>
</view>

<view class="container">
<view class='container-info'>
<view class="man-form-info">
<view class='name'>姓名
<input placeholder='请输入姓名' name="name"></input>
</view>
<view class='idcard'>
身份证号码
<input maxlength='18' placeholder='请输入身份证号码' type='idcard' name="idcard"></input>
</view>

<view class='phone'>
手机号码
<input maxlength='11' placeholder='请输入手机号码' type='number' bindinput="phoneInput" name="tel"></input>
</view>

</view>
</view>

<view class='read-man-pact'>
<checkbox-group name="assistance">
<checkbox></checkbox>
<navigator class='pact'>阅读《顺风男服务协议》</navigator>
</checkbox-group>
</view>

<view class='submit-form-info'>
<button form-type='submit'>提交</button>
</view>

</view>
</form>
