利用element-plus写一个漂亮的带图片的添加页面

好的，下面是一个利用Element Plus写的带图片的添加页面示例：

<template>
  <div class="add-page">
    <el-form :model="form" label-width="120px">
      <el-form-item label="商品名称">
        <el-input v-model="form.name" placeholder="请输入商品名称"></el-input>
      </el-form-item>
      <el-form-item label="商品价格">
        <el-input-number v-model="form.price" :min="0" :max="9999" :step="0.01"></el-input-number>
      </el-form-item>
      <el-form-item label="商品图片">
        <el-upload
          action=""
          :file-list="form.imageList"
          :show-file-list="false"
          list-type="picture-card"
          :on-success="handleUploadSuccess"
          :before-upload="beforeUpload"
          :on-exceed="handleExceed"
          :limit="1"
        >
          <i class="el-icon-plus"></i>
        </el-upload>
      </el-form-item>
      <el-form-item label="商品描述">
        <el-input v-model="form.description" type="textarea" rows="4"></el-input>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="handleSubmit">提交</el-button>
        <el-button @click="handleReset">重置</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>

<script>
export default {
  data() {
    return {
      form: {
        name: '',
        price: '',
        imageList: [],
        description: ''
      }
    }
  },
  methods: {
    beforeUpload(file) {
      const isJPG = file.type === 'image/jpeg' || file.type === 'image/png'
      if (!isJPG) {
        this.$message.error('上传图片只能是 JPG 或 PNG 格式!')
      }
      const isLt2M = file.size / 1024 / 1024 < 2
      if (!isLt2M) {
        this.$message.error('上传图片大小不能超过 2MB!')
      }
      return isJPG && isLt2M
    },
    handleUploadSuccess(response, file, fileList) {
      this.form.imageList.push({
        url: URL.createObjectURL(file.raw),
        name: file.name
      })
    },
    handleExceed(files, fileList) {
      this.$message.warning(`当前限制选择 1 张图片，本次选择了 ${files.length} 张图片，已自动筛选前一张！`)
      fileList.splice(1)
    },
    handleSubmit() {
      // 提交表单逻辑
    },
    handleReset() {
      this.form.name = ''
      this.form.price = ''
      this.form.imageList = []
      this.form.description = ''
    }
  }
}
</script>

<style lang="scss" scoped>
.add-page {
  .el-form-item__label {
    font-weight: bold;
  }

  .el-upload {
    width: 120px;
    height: 120px;
    border: 1px dashed #d9d9d9;
    border-radius: 4px;
    background-color: #f7f7f7;
    margin-top: 10px;

    .el-icon-plus {
      font-size: 28px;
      color: #999;
      line-height: 120px;
    }

    img {
      width: 100%;
      height: 100%;
      object-fit: cover;
    }
  }
}
</style>

在这个示例中，我们使用了`el-upload`组件来实现图片上传功能，并对上传的图片进行格式、大小的限制，同时在上传成功后将图片预览到页面上。你可以根据需求对页面进行样式和逻辑的修改。
