进度条复制自己？

Question

我有这个进度条，实际上更像是一个耗尽条，它的工作是每当它被点击时按钮会重置自己，如果它达到 100% 那么玩家输了，无论出于什么原因进度条决定复制自己并开始同时渲染多个进度条。

代码如下：

function move() {
  var elem = document.getElementById("DPbar");
  var width = 0; /* Starting percentage */
  var id = setInterval(frame, 100); /* Speed of depletion bar */
  function frame() {
    if (width >= 13) { /* Length of depletion bar (ending percentage) */
      clearInterval(id);
      alert("You Lose, reload (Ctrl + R) the page to play again!"); /* Message displays after hitting 100% (or whatever is the final percentage) */
    } else {
      width++;
      elem.style.width = width + '%'; /* Speed of depletion bar also (idk?) */
      elem.innerHTML = width * 7.69230769230 + '%'; /* Multiplier of percentage */
    }
  }
}

html,
body {
  height: 100%;
  margin: 0;
}

body {
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: #9898ff;
  opacity: 0.8;
  background-image: linear-gradient(to right, #4349c2, #4349c2 25px, #5e5eff 25px, #5e5eff);
  background-size: 50px 100%;
}

.PringleButton {
  background-color: #FFEA00;
  /* Pringle Color */
  border: 5px solid black;
  color: black;
  /* Text Color */
  padding: 86px 52px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 32px;
  border-radius: 100%;
  cursor: copy;
}

.PringleButton:hover {
  background-color: rgba(236, 236, 57, 0.667)
}

.PringleButton:active {
  background-color: rgba(236, 236, 57, 0.667);
  transform: scale(0.9, 0.9);
}

.DPbar {
  position: absolute;
  bottom: 200px;
  left: 725px;
  border: 2px solid black;
  background-color: seagreen;
  border-radius: 25%;
  cursor: not-allowed;
}

<!--button and depletion bar functionality-->

<!--TO DO: 1: Make DP bar length shorter + center it (DONE)
                       2: DP bar total percentage = 100% (DONE...kinda...)
                       3: Tweak depletion speed (DONE)
                       4: DP bar does not push pringle button (DONE)
                       5: Clicking multiple times does not clone the DP bar-->

<div id="DPbar" class="DPbar" style="width:0%">0%</div>
<!-- Starting percentage of depletion bar-->
<br>
<button class="PringleButton" onclick="move()">Pringle!</button>

稍微移动一下您的代码。重要的部分是在单击按钮时清除间隔（如果它已经存在）。请参阅 --> 评论
