这是一个使用微擎小程序的代码示例，其中包含了获取用户头像和昵称的功能。以下是解决方案：
-
首先，在
<button>标签上添加open-type="chooseAvatar"属性，并绑定bindchooseavatar事件：<button class="avatar-wrapper" open-type="chooseAvatar" bindchooseavatar="onChooseAvatar"><image class="avatar" src="{{avatarUrl?avatarUrl:'../../resource/icon/user.png'}}" mode="aspectFill"></image> </button> -
在Page对象中定义
onChooseAvatar函数来处理选择头像的事件：onChooseAvatar: function(event) {var that = this;wx.chooseImage({count: 1,success:function(res) {that.setData({avatarUrl: res.tempFilePaths[0]});}}); } -
在
<input>标签中加入name="nickname"属性，设置输入框的类型为昵称：<view class="cu-form-group"><view class="title">昵 称：</view><input placeholder="请输入昵称" type="nickname" name="nickname" maxlength="32"></input> </view> -
在提交表单时，通过
form标签的bindsubmit属性绑定getUserName事件处理函数。在事件处理函数中，可以使用event.detail.value获取用户输入的昵称和手机号：<form bindsubmit="getUserName">... </form>getUserName: function (event) {var nickname = event.detail.value.nickname;var mobile = event.detail.value.mobile;// 进行相应的逻辑处理 }
