在开发中，有这样一个需求，点击上传logo，点击上传封面，点击上传头像等等，每次都上传很浪费存储资源，故要实现一个图片库的功能，点击先在图片库选择，如果图片库没有在执行上传。废话少说：上图

1. 图片库页面代码

<style lang="scss" scoped>
.header_top {
display: flex;
justify-content: space-between;
align-items: center;
padding: 15px 0;
}
.table {
.imgBox {
display: flex;
.l {
img {
width: 68px;
height: 48px;
object-fit: scale-down;
background: #fafafa;
}
}
.r {
display: flex;
flex-direction: column;
margin-left: 10px;
overflow: hidden;
justify-content: space-between;
span {

}

}
.loading {
padding-bottom: 20px;

</style>
2. 组件内用到了封装的分页组件，代码如下
<template>
<div class="pagination">
<el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :page-sizes="[1,5, 10, 20, 30, 40, 50]" :layout="layout"
:current-page.sync="page" :page-size="page_size" :total="total" :background="background" small>
</el-pagination>
</div>
</template>
<script>
export default {
name: "pagination",
data() {
return {
page: 1
}
},
props: {
// 避免直接改变prop属性
// 'currentPage': {
// required: false,
// default: 1
// },
'layout': {
required: false,
default: 'total, prev, pager, next, sizes'
},
'total': {
required: false,
default: 0
},
'page_size': {
required: false,
default: 10
},
'background': {
required: false,
type: Boolean,
default: false
}
},
watch: {
currentPage(val) {
// 改变这个值并不会触发 handleCurrentChange
if (typeof val === "number") {
// console.log('prop currentPage!!!');
this.currentPage = val;
}
},
},
methods: {
// 当前页变化
handleCurrentChange(val) {
this.$emit("handleCurrentChange", val);
},
// size变化
handleSizeChange(val) {
this.currentPage = 1;
this.$emit('handleSizeChange', val);
},
}
}
</script>
<style lang="scss" scoped>
.pagination {
margin: 10px 0 0 0;
text-align: right;
}
::v-deep .el-pagination .el-select .el-input {
margin-top: -3px;
}
::v-deep .el-pagination.is-background .el-pager li {
border-radius: 50%;
}
::v-deep .el-pagination.is-background .el-pager li:not(.disabled).active {
background-color: #38a4bd;
}
::v-deep .el-pagination.is-background.el-pagination--small .btn-prev {
border-radius: 50%;
}
::v-deep .el-pagination.is-background.el-pagination--small .btn-next {
border-radius: 50%;
}
</style>
3. 写个容器调用组件
<el-form-item label="LOGO">
<div class="flex">
<el-image :src="formDataHandle.orgLogo" :preview-src-list="[formDataHandle.orgLogo]" fit="cover" lazy class="el-avatar">
<div slot="error" class="image-slot" @click="showImgFileDialog">
<i class="el-icon-picture-outline"></i>
</div>
</el-image>
<div class="dot" v-if="formDataHandle.orgLogo != ''">
<el-button class="closeicon" type="danger" circle icon="el-icon-delete" @click="delLogo"></el-button>
</div>
</div>
</el-form-item>
<ImgFileDialog :appendToBody='true' @selectImage='selectImage' :imgFileDialogFlag='imgFileDialogFlag'></ImgFileDialog>
data(){
return{
imgFileDialogFlag: {
show: false
},
}
}
methods(){
//打开图片库
showImgFileDialog() {
this.imgFileDialogFlag = {
show: true
}
},
selectImage(url) {
this.formDataHandle.orgLogo = url //赋值
this.imgFileDialogFlag = {
show: false
}
},
//删除图片重新选择
delLogo() {
this.formDataHandle.orgLogo = ''
}
}
