前端vue点击图片上传(带封装方法)

第一种

直接用，图片路径自己换一下

<template>
	<view class="uPImg">
		<view class="Img">上传照片 :view>
		<view class="shangchuan">
			<view class="sc2" v-for="(item, index) in imgList" :key="index">
				<image class="del" @click="del(index)" src="../../../static/property/paymentUpload.png" mode="">
				image>
				<image class="Img3" :src="item" mode="">image>
			view>
			<view class="sc2" v-if="imgList.length < 3" @click="upload">
				<image class="sc3" src="../../../static/property/paymentUpload.png" mode="">image>
			view>
		view>
	view>
template>

<script>
	export default {
		data() {
			imgList: [],
		},
		methods {
			// 点击上传图片
			upload() {
					uni.chooseImage({
						count: 1, //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
						loop: true,
						success: res => {
							console.log(res);
							if (res.tempFilePaths.length != 0) {
								this.imgList.push(res.tempFilePaths[0]);
							}
							console.log(JSON.stringify(res.tempFilePaths));
							var tempFilePaths = res.tempFilePaths;

							console.log(tempFilePaths);
							console.log(tempFilePaths[0]);
							uni.uploadFile({
								url: 'http://douzhuoqianshouba.xieenguoji.com/api/ajax/upload',
								filePath: tempFilePaths[0],
								name: 'file',
								success: uploadFileRes => {
									console.log('上传图片', JSON.parse(uploadFileRes.data));
								},
								fail(err) {
									console.log(err);
								}
							});
						}
					});
				},

				// // 删除图片
				del(index) {
					this.imgList.splice(index, 1);
					console.log(this.imgList);
				},
		}
	}
script>

第二种封装方法

封装组件upload.vue

直接用，图片路径自己换一下

<template>
	<view>view>
template>

<script>
export default {
	data() {
		return {
			/*需要返回的图片*/
			imageList:[]
		};
	},
	onLoad() {},
	props:['num'],
	mounted() {
		this.chooseImageFunc();
	},
	methods: {
		
		/*打开相机或者相册，选择图片*/
		chooseImageFunc() {
			let self=this;
			uni.chooseImage({
				count: self.$props.num || 9, //默认9
				sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有
				sourceType: ['album', 'camera'], //从相册选择
				success: function(res) {
					self.uploadFile(res.tempFilePaths);
				},
				fail:function(res){
					self.$emit('getImgs',null);
				},
				complete:function(res){
					
				}
			});
		},
		
		/*上传图片*/
		uploadFile: function(tempList) {
			let self = this;
			let i = 0;
			let img_length=tempList.length;
			let params = {
				token: uni.getStorageSync('token'),
                app_id: self.getAppId()
			};
			uni.showLoading({
			    title: '图片上传中'
			});
			tempList.forEach(function(filePath, fileKey) {
				uni.uploadFile({
					url: self.websiteUrl + '/index.php?s=/api/file.upload/image',
					filePath: filePath,
					name: 'iFile',
					formData: params,
					success: function(res) {
						let result = typeof res.data === 'object' ? res.data : JSON.parse(res.data);
						if (result.code === 1) {
							self.imageList.push(result.data);
						}else{
							self.showError(result.msg);
						}
					},
					complete: function() {
						i++;
						if (img_length === i) {
							uni.hideLoading();
							// 所有文件上传完成
							self.$emit('getImgs',self.imageList);
						}
					}
				});
			});
		}
	}
};

使用组件

引入上面upload.vue

<template>
	<view class=" payment_right">
		<!-- 	 src="../../../static/property/paymentUpload.png" mode="">image>
					
		<view class="uploadBox d-s-e">
			<view class="item" v-for="(imgs,img_num) in images" :key="img_num" @click="deleteFunc(imgs)">
				<image :src="imgs.file_path || imgs" mode="aspectFit">image>
			view>
			<view class="item d-c-c d-stretch" v-if="images.length<1">
				
				<view class="  flex-1" @click="openUpload()">
					<image width="100px" height="100px" src="../../../static/property/paymentUpload.png">
					image>
				view>
			view>
		view>
		<Upload v-if="isUpload" @getImgs="getImgsFunc">Upload>
		

	view>
template>

<script>
	import Upload from '@/components/upload/upload.vue';
	export default {
		components: {
			Upload,
		},
		data() {
			// 封装的完整的上传图片start
			images: [],
			isUpload: false,
			// 封装的完整的上传图片end
		},
		methods {
			// 封装的完整的上传图片start
			// 上传微信收款码 删除图片
			deleteFunc(e) {
					this.images.splice(e, 1);
				},
				/*获取图片*/
				getImgsFunc(e) {
					let self = this;
					self.isUpload = false;
					if (e && typeof(e) != 'undefined') {
						let this_length = self.images.length,
							upload_length = e.length;
						if (this_length + upload_length < 2) {
							self.images = self.images.concat(e);
						} else {
							let leng = 1 - this_length;
							for (let i = 0; i < leng; i++) {
								self.images.push(e[i]);
							}
						}
					}

					this.pay_image = e[0].file_path
					// console.log(e, '获取所有图片');
					console.log(e[0].file_path, '图片路径');

				},
				/*上传*/
				openUpload() {
					this.isUpload = true;
					// console.log('打开');
				},
				// 封装完整的上传图片end
		}
	}
