🏯 Basic Usage Example

Template

<template>
    <hy-coupon
        title="New Product Coupon"
        amount="10"
        description="This is for new product testing"
        date-desc="Valid long-term"
        type="moneyOff"
        status="unused"
        btnMode="button"
        :disabled-status="['used', 'expired', 'redeemed']"
        @used="onUse"
    />
</template>

Custom Background Color

You can customize the coupon's background color by setting the bg-color property, which supports solid colors, gradients, or complex CSS background styles.

1. Using a Gradient Background

<template>
    <hy-coupon
        title="New Product Coupon"
        amount="10"
        description="This is for new product testing"
        date-desc="Valid long-term"
        type="moneyOff"
        status="unused"
        :disabled-status="['used', 'expired', 'redeemed']"
        bg-color="linear-gradient(135deg, #7b61ff 0%, #4134c1 100%)"
        @used="onUse"
    />
</template>

2. Using Custom Styles to Create a Middle Notch Effect

If you need to create a middle notch effect, you can use complex CSS background styles:

Template

<template>
    <hy-coupon
        title="New Product Coupon"
        amount="10"
        description="This is for new product testing"
        date-desc="Valid long-term"
        type="moneyOff"
        status="unused"
        :disabled-status="['used', 'expired', 'redeemed']"
        :bgColor="bgColor"
        @used="onUse"
    />
</template>

<script lang="ts" setup>
    import { ref } from 'vue';

    const bgColor = {
        background: `
    radial-gradient(circle at 180rpx top, transparent 15rpx, #00c6ff 0) top / 100% 60px no-repeat,
    radial-gradient(circle at 180rpx bottom, transparent 15rpx, #00c6ff 0) bottom / 100% 51px no-repeat
  `,
    };

    const onUse = () => {
        // Logic for using the coupon
    };
</script>

Friendly Reminder

• 15rpx controls the size of the notch
• 60px and 51px control the heights of the top and bottom sections, which can be adjusted as needed to avoid gaps
