Vue3评分（Rate）

①创建评分组件Rate.vue：

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

  allowClear?: boolean // 是否允许再次点击后清除
  allowHalf?: boolean // 是否允许半选
  count?: number // star 总数
  character?: string // 自定义字符，string | slot，预置 'star-outlined' 'star-filled' 'heart-outlined' 'heart-filled' 四种svg图标
  size?: number // 字符时是字体高度，图标时是图片大小
  color?: string // 字符选中颜色
  gap?: number // 字符间距
  disabled?: boolean // 只读，无法进行交互
  value?: number // v-model 当前数，受控值 1,2,3...
}
const props = withDefaults(defineProps<Props>(), {

})
const activeValue = ref(props.value)
const tempValue = ref() // 清除时保存点击value
