二次封装el-update组件(vue2.x)

一、单张图片上传

组件 Upload.vue

<template>
  <div>
    <el-upload
      class="pic-uploader-component"
      action="上传地址"
      :show-file-list="false"
      :on-success="handleUploadSuccess"
      :on-change="handleChange"
      :before-upload="beforeAvatarUpload"
    >
      <img v-if="value && !loading" :src="resourcesUrl + value" class="pic">
      <i v-if="!value && !loading" class="el-icon-plus pic-uploader-icon" />
      <i v-if="loading" class="el-icon-loading pic-uploader-icon" />
    </el-upload>
  </div>
</template>
<script>
export default {
  props: {
    value: {
      default: '',
      type: String
    }
  },
  data() {
    return {
        loading: false,
        resourcesUrl: '',
    }
  },
  methods: {
    handleChange(){
        this.loading = false
    },
    // 图片上传
    handleUploadSuccess(response, file, fileList) {
        console.log(file)
        this.$emit('input', file.response)
        this.loading = false
    },
    // 限制图片上传大小
    beforeAvatarUpload(file) {
        this.loading = true
        const isLt2M = file.size / 1024 / 1024 < 2
        if (!isLt2M) {
            this.$message.error('上传图片大小不能超过 2MB!')
        }
        return isLt2M
    }
  }
}
</script>
<style lang="scss">
  .pic-uploader-component .el-upload {
    border: 1px dashed #d9d9d9;
    border-radius: 6px;
    cursor: pointer;
    position: relative;
    overflow: hidden;
    .pic-uploader-icon {
      font-size: 28px;
      color: #8c939d;
      width: 120px;
      height: 120px;
      line-height: 120px;
      text-align: center;
    }
    .pic {
      width: 120px;
      height: 120px;
      display: block;
    }
  }
  .pic-uploader-component .el-upload:hover {
    border-color: #409EFF;
  }
</style>

引入注册后的使用方式

<upload v-model="url"></upload>

二、多张图片上传（待更新）
