vue中随机十六进制

调用

 this.generateColorsArray(需要生成颜色的个数)

   generateRandomColor() {
      const letters = "0123456789ABCDEF";
      let color = "#";
      for (let i = 0; i < 6; i++) {
        color += letters[Math.floor(Math.random() * 16)];
      }
      return color;
    },
    generateColorsArray(length) {
      const colors = [];
      for (let i = 0; i < length; i++) {
        colors.push(this.generateRandomColor());
      }
      return colors;
    },
