從 ES2019 中開始引入了一種扁平化數組的新方法，可以展平任何深度的數組。 ### flat `flat()` 方法創建一個新數組，其中所有子數組元素以遞歸方式連接到特定深度。 > 語法：array.flat(depth) - **array** ： `flat()` 方法將在給定的數組中使用。 ...
前端vue單個文件上傳支持圖片，壓縮包以及文件 ， 下載完整代碼請訪問uni-app插件市場址:https://ext.dcloud.net.cn/plugin?id=13066
效果圖如下：
使用方法
<!-- photoList：選擇的圖片數組 @click：圖片選擇事件-->
<ccChooseImgsView :photoList="photoList" @click="addPhotoClick"></ccChooseImgsView>
addPhotoClick() {
uni.hideLoading();
let myThis = this;
if (myThis.photoList.length >= 1) {
myThis.photoList = [];
}
uni.chooseImage({
count: 1,
sizeType: ['compressed'], //可以指定是原圖還是壓縮圖，預設二者都有
sourceType: ['album'], //從相冊選擇
success: function(res) {
myThis.photoList = [{'filePath':res.tempFilePaths[0]}];
console.log('選擇圖片 =' + JSON.stringify(myThis.photoList));
}
});
},
if (this.photoList.length > 0) {
myFilePath = this.photoList[0].filePath;
}
// 伺服器地址上傳地址 僅為示例，非真實的介面地址
let baseUrl = "http://gzcc.com/cc//appSc/up"
uni.uploadFile({
url: baseUrl, //僅為示例，非真實的介面地址
filePath: myFilePath, //文件路徑
name: 'image', //服務端文件接受key
formData: this.myParamData,
success: (uploadFileRes) => {
uni.hideLoading();
let dataDic = JSON.parse(uploadFileRes.data);
console.log('uploadFileRes成功 = ' + JSON.stringify(uploadFileRes));
console.log('datadic成功 = ' + typeof(dataDic));
console.log('code碼 = ' + dataDic['code']);
}
});
HTML代碼部分
<template>
<view class="content" v-if="seen">
<form @submit="formSubmit" @reset="formReset">
<view class="inputView">
<text class="leftTitle">交通指引</text>
</view>

<!-- photoList：選擇的圖片數組 @click：圖片選擇事件-->
<ccChooseImgsView :photoList="photoList" @click="addPhotoClick"></ccChooseImgsView>
