我想讓它單獨(dú)顯示例如 1 2 3 4 5，而不是僅顯示最終結(jié)果 5。我真的不知道為什么它會(huì)這樣顯示。我將如何實(shí)現(xiàn)，以便它顯示它一次遞增一個(gè)？var pushups = 0;var i = 0;var pushupGoal = 5;function doExercise() {  while (i == 0) {    if (pushups < pushupGoal) {      console.log(pushups);      document.getElementById("pushup1").innerHTML = ++pushups + ' pushups';      if (pushups == pushupGoal) {        document.getElementById("pushup1").innerHTML = pushups + ' pushups. You reached your goal!';        i += 1      }    }  }}<div class="container justify-content-center">  <h1>Pushups</h1>  <h4 id="pushup1">0 pushups</h4>  <button class="btn btn-primary" onClick="doExercise()">Start</button></div>
