分割emoji数组的方法

   newEmojiList() {
    
    
      const emojiNum = this.emojiList.length;
      const num = 21; //每一页表情个数
      let pageNum; //总共有几页表情（通过计算后获得）
      const m = (emojiNum / num) | 0;
      if (m * num == emojiNum) {
    
    
        pageNum = m;
      }
      if (m * num < emojiNum && (m + 1) * num > emojiNum) {
    
    
        pageNum = m + 1;
      }
      const result = [];
      for (let x = 0; x < num; x++) {
    
    
        const start = x * num;
        const end = start + num;
        result.push(this.emojiList.slice(start, end));
      }
      result.splice(pageNum, emojiNum - 1);
      this.emoji = result;
    },
