效果图如下：
#### 使用方法
```使用方法
<!-- photoList：选择的图片数组 @click：图片选择事件-->
<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'], //可以指定是原图还是压缩图，默认二者都有
sourceType: ['album'], //从相册选择
success: function(res) {
myThis.photoList = [{'filePath':res.tempFilePaths[0]}];
console.log('选择图片 =' + JSON.stringify(myThis.photoList));
}
});
},
if (this.photoList.length > 0) {
myFilePath = this.photoList[0].filePath;
}
// 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"
uni.uploadFile({
url: baseUrl, //仅为示例，非真实的接口地址
filePath: myFilePath, //文件路径
name: 'image', //服务端文件接受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码 = ' + dataDic['code']);
}
});
```
#### HTML代码部分
```html
<template>
<view class="content" v-if="seen">
<form @submit="formSubmit" @reset="formReset">
<view class="inputView">

</view>
<textarea class="rightTextarea" name="direct" placeholder=" 请输入交通指引" />

<textarea class="rightTextarea" name="village" placeholder=" 请输入房屋介绍" />
<view class="inputView">
<text class="leftTitle">添加房源照片（仅可添加1张）</text>
</view>
<!-- photoList：选择的图片数组 @click：图片选择事件-->
<ccChooseImgsView :photoList="photoList" @click="addPhotoClick"></ccChooseImgsView>
<view class="uni-btn-v">
<button class="botBtn" type="primary" form-type="submit">提交</button>
<view class="tipText"> 注意事项: 请确保您填写的房屋信息真实无误 </view>
</view>
</form>
</view>
</template>
```
#### JS代码 （引入组件 填充数据）
```javascript
<script>
import Vue from 'vue';
import ccChooseImgsView from '../../components/ccChooseImgsView.vue';
export default {
components: {
ccChooseImgsView
},
data() {
return {
photoList: [],
seen: true,
myParamData: {},
isClick: false,
};
},
onLoad: function(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;
}
if (formdata['village'].length < 2) {
uni.showModal({
content: '请输入所在小区介绍',
showCancel: false
});
return;
}
if (this.photoList.length < 1) {
uni.showModal({
content: '请添加房源照片',
showCancel: false
});
return;
}
uni.showLoading({
title: '上传中'
})
let myFilePath = '';
if (this.photoList.length > 0) {
myFilePath = this.photoList[0].filePath;
}
// 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"
uni.uploadFile({
url: baseUrl, //仅为示例，非真实的接口地址

console.log('uploadFileRes成功 = ' + JSON.stringify(uploadFileRes));
console.log('datadic成功 = ' + typeof(dataDic));
console.log('code码 = ' + dataDic['code']);
}
});
},
addPhotoClick() {
uni.hideLoading();
let myThis = this;
