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
组件代码文件结构
src/components/StampBadge/src/StampBadge.vue 文件代码
<template>
<div
class="first-ring"
v-bind="getBindValue"
:class="getStampBadgeClass"
:
>
<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 lang="ts">
import { defineComponent } from "vue";
export default defineComponent({
name: "StampBadge",
inheritAttrs: false,
});
</script>
<script lang="ts" setup>
import { computed, unref } from "vue";
import { stampBadgeProps } from "./props";
import { useAttrs } from "/@/hooks/core/useAttrs";
const props = defineProps(stampBadgeProps);
// get component class
const attrs = useAttrs({ excludeDefaultKeys: false });
const getStampBadgeClass = computed(() => {
const { color, size } = props;
return [
{
[`stamp-badge-${color}`]: !!color,
[`stamp-badge-${size}`]: !!size,
},
];
});
// get inherit binding value
const getBindValue = computed(() => ({ ...unref(attrs), ...props }));
</script>
<style lang="less" scoped>

}
.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 {

font-size: 0.8rem;
}
</style>src/components/StampBadge/src/props.ts 文件代码
export const stampBadgeProps = {
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" },
};src/components/StampBadge/index.ts 文件代码
import { withInstall } from "/@/utils";
import type { ExtractPropTypes } from "vue";
import stampbadge from "./src/StampBadge.vue";
import { stampBadgeProps } from "./src/props";
export const StampBadge = withInstall(stampbadge);
export declare type ButtonProps = Partial<
ExtractPropTypes<typeof stampBadgeProps>
>;src/utils/index.ts 文件代码
export const withInstall = <T>(component: T, alias?: string) => {
const comp = component as any;
comp.install = (app: App) => {
app.component(comp.name || comp.displayName, component);
if (alias) {
app.config.globalProperties[alias] = component;
}
};
return component as T & Plugin;
};二、组件全局注册代码
src/components/registerGlobComp.ts 文件代码
import type { App } from "vue";
import { StampBadge } from "./StampBadge";
export function registerGlobComp(app: App) {
app.use(StampBadge);
}src/main.ts 文件代码
import { createApp } from "vue";
import App from "./App.vue";
import { registerGlobComp } from "/@/components/registerGlobComp";
async function bootstrap() {
// 创建应用实例
const app = createApp(App);
// 注册全局组件
registerGlobComp(app);
// 挂载应用
app.mount("#app", true);
}
bootstrap();三、组件应用代码
<div > <StampBadge size="middle" color="success" content="已建档" :rotate="45" /> </div>
