创建注册页

pages\register\index.wxml

<view class="box"><form wx:if="{{type == '注册'}}" bindsubmit="saveInfo"><input maxlength="10" name='nickname' type="nickname" placeholder="请输入昵称" /><radio-group class="radioBox" name='gender'><radio color='#027CBE' checked value='1'>男</radio><radio color='pink' value='2'>女</radio></radio-group><input maxlength="20" name='identification' placeholder="请输入微信号/可添加微信的手机号" /><button form-type="submit">注册</button></form><view wx:if="{{type == '已注册'}}" class="resultBox"><t-result wx:if="{{userInfo.accountStatus === '被拒绝'}}" theme="error" title="您的申请未通过" description="可微信咨询 sunshinehu39" /><t-result wx:else theme="success" title="注册信息已提交" description="请耐心等待审核结果" /></view>
</view>

• input 标签的 type 为 nickname 时，用户点击该输入框，会出现用户微信昵称的快捷输入，方便用户快速输入微信的昵称（用户也可输入其他昵称）
