Vue2 实现印章徽章组件

需要实现的组件效果：

该组件有设置颜色、大小、旋转度数和文本内容功能。

一、组件实现代码

<template>
  <div
    class="first-ring"
    v-bind="getBindValue"
    :class="getStampBadgeClass"
    :style="{ transform: `rotate(${rotate}deg)` }"
  >
    <div class="second-ring" :class="getStampBadgeClass">
      <div class="third-ring" :class="getStampBadgeClass">
        <div class="forth-ring" :class="getStampBadgeClass">
          <div class="content-rectangle ellipsis" :class="getStampBadgeClass">
            <span class="">{{ content }}</span>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

<script>
  export default {
    name: "StampBadge",
    // inheritAttrs: false,
    props: {
      color: {
        type: String,
        default: "primary",
        validator: (v) =>
          ["primary", "error", "warning", "success", "info"].includes(v),
      },
      /**
       * stamp badge size.
       * @default: middle
       */
      size: {
        type: String,
        default: "middle",
        validator: (v) => ["large", "middle", "small"].includes(v),
      },
      /**
       * stamp badge rotate deg.
       * @default: 0
       */
      rotate: { type: Number, default: 0 },
      content: { type: String, default: "Unknown" },
    },
    computed: {
      getStampBadgeClass() {
        const { color, size } = this.$props;
        return [
          {
            [`stamp-badge-${color}`]: !!color,
            [`stamp-badge-${size}`]: !!size,
          },
        ];
      },
      getBindValue() {
        return { ...this.$attrs, ...this.$props };
      },
    },
    methods: {},
  };
</script>

<style lang="less" scoped>
  .first-ring {
    border-radius: 100px;
    display: flex;
    justify-content: center;
    align-items: center;
  }

  .second-ring {
    background: #fff;
    border-radius: 100px;
    display: flex;
    justify-content: center;
    align-items: center;
  }

  .third-ring {
    border-radius: 100px;
    display: flex;
    justify-content: center;
    align-items: center;
  }

  .forth-ring {
    background: #fff;
    border-radius: 100px;
    display: flex;
    justify-content: center;
    align-items: center;
    position: relative;
  }

  .content-rectangle {
    background: #fff;
    font-weight: bold;
    text-align: center;
    position: absolute;
  }

  .ellipsis {
    overflow: hidden;

  }

  // primary
  .stamp-badge-primary.first-ring {
    background: #1890ff;
  }

  .stamp-badge-primary.third-ring {
    background: #1890ff;
  }

  .stamp-badge-primary.content-rectangle {
    border: 1px solid #1890ff;
    color: #1890ff;
  }

  // success
  .stamp-badge-success.first-ring {
    background: #52c41a;
  }

  .stamp-badge-success.third-ring {
    background: #52c41a;
  }

  .stamp-badge-success.content-rectangle {
    border: 1px solid #52c41a;
    color: #52c41a;
  }

  // error
  .stamp-badge-error.first-ring {
    background: #ff4d4f;
  }

  .stamp-badge-error.third-ring {
    background: #ff4d4f;
  }

  .stamp-badge-error.content-rectangle {
    border: 1px solid #ff4d4f;

  }

  // info
  .stamp-badge-info.first-ring {
    background: #ccc;
  }

  .stamp-badge-info.third-ring {
    background: #ccc;
  }

  .stamp-badge-info.content-rectangle {
    border: 1px solid #ccc;
    color: #ccc;
  }

  // large
  .stamp-badge-large.first-ring {
    width: 84px;
    height: 84px;
  }

  .stamp-badge-large.second-ring {
    width: 80px;
    height: 80px;
  }

  .stamp-badge-large.third-ring {
    width: 74px;
    height: 74px;
  }

  .stamp-badge-large.forth-ring {
    width: 64px;
    height: 64px;
  }

  .stamp-badge-large.content-rectangle {
    width: 90px;
    font-size: 1.2rem;
  }

  // middle
  .stamp-badge-middle.first-ring {
    width: 64px;
    height: 64px;
  }

  .stamp-badge-middle.second-ring {
    width: 60px;
    height: 60px;
  }

  .stamp-badge-middle.third-ring {
    width: 56px;
    height: 56px;
  }

  .stamp-badge-middle.forth-ring {
    width: 48px;
    height: 48px;
  }

  .stamp-badge-middle.content-rectangle {
    width: 70px;
    font-size: 1rem;
  }

  // small
  .stamp-badge-small.first-ring {
    width: 54px;
    height: 54px;

    height: 50px;
  }

  .stamp-badge-small.third-ring {
    width: 46px;
    height: 46px;
  }

  .stamp-badge-small.forth-ring {

  }

  .stamp-badge-small.content-rectangle {
    width: 60px;
    font-size: 0.8rem;
  }
</style>

二、组件应用代码：

<div style="width: 500px; height: 100px; position: relative">
  <StampBadge
    style="position: absolute; top: 0; right: 0"
    size="middle"
    color="success"
    content="已支付"
    :rotate="45"
  />
</div>
