Element UI 实现上传图片的功能

只需要把

<el-upload action="">中的action等于增加方法的地址，即ajax中url等于的东西
上传图片时，默认name=file

Element UI 实现上传图片功能的代码如下：

<template>
<!--<div>轮播</div>-->
  <div class="login-box">

    <el-upload
      class="upload-demo"
      action="http://localhost:8080/lunbo/insert"
      :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 {
        name: "add-file",
      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) {
          console.log(file, 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`);
        },
