最终实现效果:

2.核心思路

核心思路：动态计算每颗星的填充比例

      getStarWidth(index) {if (this.disabled && this.showScore) {const decimal = this.value - index;return decimal >= 1 ? '100%' : `${Math.max(decimal, 0) * 100}%`;}if (this.hoverValue === -1) {const decimal = this.value - index;return decimal >= 1 ? '100%' : '0%';}const decimal = this.hoverValue - index;return decimal >= 1 ? '100%' : '0%';},
