此篇博客关键是记录这种假删除的思想,后端给的删除接口也不一定非要用。。。
上传文件假删除:
<template>
<div>
<el-upload
class="upload-demo"
action="https://jsonplaceholder.typicode.com/posts/"
:on-preview="handlePreview"
:on-remove="handleRemove"
:before-remove="beforeRemove"
multiple
:limit="3"
:on-exceed="handleExceed"
:file-list="fileList">
<el-button size="small" type="primary">点击上传</el-button>
<div slot="tip" class="el-upload__tip">只能上传jpg/png文件,且不超过500kb</div>
</el-upload>
</div>
</template>
<script>
export default {
data () {
return {
fileList: [{ name: 'food.jpeg', url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100' }, { name: 'food2.jpeg', url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100' }]
}
},
methods: {
handleRemove (file, fileList) {
// 文件即可假删除,无需调用后端接口
this.fileList = fileList
},
handlePreview (file) {
console.log(file)
},
handleExceed (files, fileList) {
this.$message.warning(`当前限制选择 3 个文件,本次选择了 ${files.length} 个文件,共选择了 ${files.length + fileList.length} 个文件`)
},
beforeRemove (file, fileList) {
return this.$confirm(`确定移除 ${file.name}?`)
}
}
}
</script>
表格数据假删除:更适合于数据不是很多的表格,无分页的
