Vue实现自定义组件改变组件背景色(示例代码)

<template>
  <div :style="{ backgroundColor: backgroundColor }">
    <slot></slot>
  </div>
</template>
<script>
export default {
  props: {
    backgroundColor: {
      type: String,
      default: 'white' // 默认背景色为白色
    }
  }
}
</script>
<style scoped>
/* 组件样式 */
div {
  padding: 20px;
  border: 1px solid #ccc;
}
</style>

<template>
  <div>
    <custom-component :background-color="bgColor">
      <h1>Custom Component with Dynamic Background Color</h1>
      <p>This is a custom component with dynamic background color.</p>
    </custom-component>
    <button @click="changeColor">Change Background Color</button>
  </div>
</template>
<script>
import CustomComponent from './CustomComponent.vue';
export default {
  components: {
    CustomComponent
  },
  data() {
    return {
      bgColor: 'lightblue'
    };
  },
  methods: {
    changeColor() {
      this.bgColor = this.getRandomColor();
    },
    getRandomColor() {
      // 生成随机颜色
      return '#' + Math.floor(Math.random() * 16777215).toString(16);
    }
  }
}
</script>
