前端vue uni-app多图片上传组件，支持单个文件，多个文件上传步骤条step使用

快速实现多图片上传组件，支持单个文件，多个文件上传步骤条step使用; 下载完整代码请访问uni-app插件市场地址：https://ext.dcloud.net.cn/plugin?id=12747

效果图如下:

使用方法



// 添加多张图片（少于6张）

addPhotoClick() {

uni.hideLoading();

let myThis = this;

if (myThis.photoList.length >= 6) {

myThis.photoList = [];

}

uni.chooseImage({

count: 6,

sizeType: ['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: function(res) {

for (let j = 0; j < res.tempFilePaths.length; j++) {

// name：服务端文件接受key  filePath: 需与服务端文件接收字段保持一致

let tmpdict = {

'name': 'image',

'filePath': res.tempFilePaths[j]

};

myThis.photoList.push(tmpdict);

}

console.log('选择图片 =' + JSON.stringify(myThis.photoList));

}

});

}

// 服务器地址上传地址 仅为示例，非真实的接口地址

let baseUrl = "http://gzcc.com/cc//appSc/up"

console.log('图片资源 = ' + JSON.stringify(this.photoList))

console.log('请求参数 = ' + JSON.stringify(this.myParamData));

uni.uploadFile({

url: baseUrl, //仅为示例，非真实的接口地址

files: this.photoList,

formData: this.myParamData,

success: (uploadFileRes) => {

uni.hideLoading();

console.log('上传成功 = ' + uploadFileRes.data);

}

});

JS代码（引入组件填充数据）

javascript



<script>

import Vue from 'vue';

export default {

data() {

return {

photoList: [],

seen: true,

myParamData: {},

isClick: false,

};

},

onLoad: function(e) {

if (typeof(e.myParamData) === 'string') {

this.myParamData = JSON.parse(e.myParamData);

console.log('页面3 数据 = ' + JSON.stringify(e));

}

},

methods: {

formSubmit: function(e) {

console.log('form发生了submit事件，携带数据为：' + JSON.stringify(e.detail.value));

if (this.isClick) {

let that = this;

setTimeout(function() {

that.isClick = false;

}, 600)

return;

}

this.isClick = true;

var formdata = e.detail.value;

this.myParamData = Object.assign(this.myParamData, formdata);

console.log('页面3 myParamData=' + JSON.stringify(this.myParamData));

if (formdata['direct'].length < 2) {

uni.showModal({

content: '请输入交通指引',

showCancel: false

});

return;

}

content: '请添加房源照片',

showCancel: false

});

return;

}

if (this.photoList.length > 6) {

uni.showModal({

content: '最多只能选择提交6张图片',

showCancel: false

});

return;

}

uni.showLoading({

title: '上传中'

})

// 服务器地址上传地址 仅为示例，非真实的接口地址

let baseUrl = "http://gzcc.com/cc//appSc/up"

console.log('图片资源 = ' + JSON.stringify(this.photoList))

},

// 添加多张图片（少于6张）

addPhotoClick() {

uni.hideLoading();

let myThis = this;

}

uni.chooseImage({

sourceType: ['album'], //从相册选择
