wx.chooseMedia返回结果显示未定义？
API组件名称：wx.chooseMedia 微信版本号：Android 8.0.9 基础库：2.19.4 根据腾讯教程做图片上传功能，最后提示“未定义” ，代码如下 <!--pages/demo-04/demo04.wxml--> <view class="comment"> <view class="comment-upload"> <view class="comment-upload-add" bindtap="uploadImg"> <text class="comment-upload-add-icon">+</text> <text class="comment-upload-add-des">点击上传图片</text> </view> <image src="{{form.img}}" class="comment-upload-thumbnail" ></image> </view> <textarea class="comment-text" placeholder="打开脑洞，留下评论！"></textarea> <button class="comment-save">保存</button> </view> /* pages/demo-04/demo04.wxss */ Page{ width: 100%; height: 100%; } .comment{ display: flex; flex-direction: column; width: 100%; height: 100%; } .comment-upload{ flex: 0 0 400rpx; /* margin: 20rpx 20rpx 0; */ padding:20rpx 20rpx 0; } .comment-upload-thumbnail{ background-color: gold; width: 100%; height: 400rpx; } .comment-upload-add{ display: flex; flex-direction: column; align-items: center; justify-content:center; background-color:#eff1f3; color: #bfbfbf; height: 400rpx; } .comment-text{ flex: 1; box-sizing: border-box; width: 100%; padding: 30rpx; font-size: 28rpx; } .comment-upload-add-icon{ font-size: 200rpx; line-height: 1; margin-top:-40; } .comment-save{ flex: 0 0 90rpx; margin: 20rpx; /*margin是指定周边的距离值，值是上右下左的顺序*/ background-color: #33c9ff; color: #fff; } // pages/demo-04/demo04.js Page({ data: { form:{ img:'' } }, uploadImg:function(){ wx.chooseMedia({ count: 9, mediaType: ['image','video'], sourceType: ['album', 'camera'], maxDuration: 30, camera: 'back', success:(res) => { console.log(res) // console.log(res.tempFiles.tempFilePath) // console.log(res.tempFiles.size) this.setData({ 'form.img':res.tempFilePaths[0] }) } }) } }) [图片]
