Question

我正在创建一个简单的游戏，修改我的HTML并跟踪我正在键入的键。当我有一定的分数时，我输入的键应该从我的段落元素中清除，但它不会被清除。我正在使用innerHTML并将其设置为等于空字符串。它永远不会清除。

var losses = 0;
var guessesLeft = 10;
var guesses = guessesLeft;    

document.onkeypress = function(event) {

  var userChoice = event.key;
  console.log("guesses" + guesses);

  if (guesses === guessesLeft) {
       console.log("Will this work" + userChoice);
       document.getElementById('guess').innerHtml = "";
       var newContent = document.createTextNode(userChoice); 
  } else {
       var newContent = document.createTextNode(', ' + userChoice);
  }
  console.log("newContent" + newContent[0]);
  var newEl = document.createElement('span').appendChild(newContent);
  document.getElementById('guess').appendChild(newEl);

  if (guesses === 0) {
      losses++;
      document.getElementById('losses').innerHTML = ("Losses: " + losses);
      guesses = guessesLeft;
   }
};

<div class="container"> 

<div class="row"> 

    <div class="col-lg-12 jumbotron">

         <h1> The Psychic Game </h1>

    </div>

</div>

<div class="row">

    <div class="col-lg-4 one"> 



    </div>

    <div class="col-le-4 content"> 

        <p> Guess what letter I'm thinking of? </p> 

        <p id="wins"> Wins: </p>

        <p id="losses"> Losses: </p>

        <p id="left"> Guesses Left:  </p>

        <div> 
            <p> Your guesses so far: <span id="guess"> </span></p>

        </div>

  </div>
</div>

以下是修改后的代码。所有我改变的是innerHtml到innerText并添加了猜测 - 在if（猜测=== 0）条件的else部分。

我希望这会有所帮助。

var losses = 0;
var guessesLeft = 10;
var guesses = guessesLeft;    

document.onkeypress = function(event) {

  var userChoice = event.key;
  console.log("guesses" + guesses);

  if (guesses === guessesLeft) {
       console.log("Will this work" + userChoice);
       document.getElementById('guess').innerText = "";
       var newContent = document.createTextNode(userChoice); 
  } else {
       var newContent = document.createTextNode(', ' + userChoice);
  }
  console.log("newContent" + newContent[0]);
  var newEl = document.createElement('span').appendChild(newContent);
  document.getElementById('guess').appendChild(newEl);

  if (guesses === 0) {
      losses++;
      document.getElementById('losses').innerHTML = ("Losses: " + losses);
      guesses = guessesLeft;
   }
else
	guesses--;
};

<div class="container"> 

<div class="row"> 

    <div class="col-lg-12 jumbotron">

         <h1> The Psychic Game </h1>

    </div>

</div>

<div class="row">

    <div class="col-lg-4 one"> 



    </div>

    <div class="col-le-4 content"> 

        <p> Guess what letter I'm thinking of? </p> 

        <p id="wins"> Wins: </p>

        <p id="losses"> Losses: </p>

        <p id="left"> Guesses Left:  </p>

        <div> 
            <p> Your guesses so far: <span id="guess"> </span></p>

        </div>

  </div>
