    实现思路

    • 将目标字符串按字符转换为数组，遍历展示
          this.stringLib[this.step].split("").forEach((item) => {
        this.targetList.push({
          text: item,
        });
      });

    • 5
    • 监听键盘事件
    created() {
  this.keyDown();
},

    • 1
    • 2
    • 3
    // 按下按键
keyDown() {
   // function内的this不再是vue实例，需提前将 this 存入 that以便在 function内使用
   let that = this;
   document.onkeydown = function (e) {
       console.log(e.key) // 按下键盘上的 A 时会打印 a
   }
}

    • 根据按键值判断输入是否正确，若正确则添加属性 type 为 success ，字符变绿 ；输入错误则添加属性 type 为 danger，字符变红 （type 值来自 el-tag 对应的效果）
    // 用下标 index 跟踪标记输入进度
let targetText = that.targetList[that.index].text;
if (e.key === targetText) {
  // 使用 $set 页面才能及时响应对象的变化
  that.$set(that.targetList[that.index], "type", "success");
} else {
  that.$set(that.targetList[that.index], "type", "danger");
}

    • 8
    • 当前关的字符输入完后，按任意键都会判定通关结果，输入全部正确才能通关
    // 输入的正确字符数与目标字符数相等时，通过当前关
if (that.rightCharNum === that.targetList.length) {
  // 若已是最后一关，则全部通关，闯关结束
  if (that.step === that.totalStep) {
    that.over();
  } else {
    that.result = "success";
    // 通过当前关时播放通关成功的音效
    that.$refs.successAudio.play();
  }
} else {
  that.result = "fail";
  // 存在错误字符时播放通关失败的音效
  that.$refs.failAudio.play();
}

    • 判定结果后，按回车键/空格键，若通关则开始下一关，若失败则重新挑战
    if (that.result) {
  if (e.key === "Enter" || e.key === " ") {
    if (that.result === "success") {
      that.nextStep();
    }
    if (that.result === "fail") {
      that.replay();
    }
  }
  return;

    • 为提升用户体验，每一次输入都会配音效，并统计输入正确和错误的次数
     if (e.key === targetText) {
   that.$set(that.targetList[that.index], "type", "success");
   // 为避免输入过快时声音反应不及时，在每次输入时让音频从头开始播放
   that.$refs.inputAudio.currentTime = 0;
   that.$refs.inputAudio.play();
   that.rightNum++;
 } else {
   that.$set(that.targetList[that.index], "type", "danger");
   that.$refs.errorAudio.currentTime = 0;
   that.$refs.errorAudio.play();
   that.wrongNum++;
 }
