[JavaScript知识库]uni-app中使用uni.chooseImage上传多张图片

我的需求是点击某个按钮或者图标去上传图片，但是这个功能只能每次选一张，需要多次点击。

html:

                    <view class="img-box">
						<view class="im-con" v-for="(item,index) in fileList" :key="index">
							<image :src="item" mode=""></image>
						</view>
						<view class="upload" @click="uploadImg" v-if="uploadFlag">
							<u-icon name="camera-fill" color="#333333" size="28"></u-icon>
							<text>照片/视频</text>
						</view>
					</view>

data:

//存放图片的集合
fileList: [],

js:

		uploadImg() {
				let that = this
				uni.chooseImage({
					count: 3, //默认9
					sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有
					sourceType: ['album'], //从相册选择
					success: (chooseImageRes) => {
						// uni.setStorageSync("token", this.token)
						console.log("token", that.token)
						// this.personInfo.avatarImg = chooseImageRes.tempFilePaths[0]
						// uni.setStorageSync("token",this.token)
						            
            
         console.log("chooseImageRes.tempFilePaths[0]",chooseImageRes.tempFilePaths[0])
						uni.uploadFile({
                            //请求地址可以放在vuex中或者公用js中
							url: 'http://81.70.239.172:9998/kst-client/uploadFile',
							filePath: chooseImageRes.tempFilePaths[0],
							name: 'files',
							formData: {},
							header: {
								token: that.token
							},
							success: (uploadFileRes) => {
								//console.log("uploadFileRes", uploadFileRes)
								 
              this.uploadFileList.push(JSON.parse(uploadFileRes.data).data[0])
								this.fileList.push(this.imgUrl + 
              JSON.parse(uploadFileRes.data).data[0])
								console.log("fileList", this.fileList)
                               //图片超过3张就让点击上传的图标隐藏，这里没有写删除图片功能
								if(this.fileList.length>=3){
									that.uploadFlag = false
								}else{
									that.uploadFlag = true
								}
							}
						})
					}
				});
