怎么保存在变量里面呢
<view data-weui-theme="{{theme}}">
<button class="avatar-wrapper" open-type="chooseAvatar" bind:chooseavatar="onChooseAvatar">
<image class="avatar" src="{{avatarUrl}}"></image>
</button>
<mp-form>
<mp-cells>
<mp-cell title="昵称">
<input type="nickname" class="weui-input" placeholder="请输入昵称"/>
</mp-cell>
</mp-cells>
</mp-form>
</view>
getUserNickName(e) { this.setData({ nickName: e.detail.value }) }, 头像不是给了示例么，昵称在input上绑定 bindinput="getUserNickName"
