Question

我正在尝试使用切换按钮来更改消息，但遗憾的是，如果您继续按下，则无效。

这是我的HTML代码：

toggled = true;
togBtn.onclick = function() {
  var text = "SELL"
  if (!toggled) {
    document.getElementById("test1").style.display = "none";
    toggled = true;
  }
  if (toggled) {
    document.getElementById("test1").innerHTML = text;
    toggled = false;
  }
};

#newsletter {
  color: #ffffff;
  background: #1d3030;
  height: 60px;
}

#newsletter h1 {
  float: left;
  padding-left: 600px;
}

#newsletter form {
  float: right;
}

.switch {
  position: relative;
  display: inline-block;
  width: 115px;
  height: 34px;
}

.switch input {
  display: none;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #e8491d;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked+.slider {
  background-color: #2196F3;
}

input:focus+.slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked+.slider:before {
  -webkit-transform: translateX(80px);
  -ms-transform: translateX(80px);
  transform: translateX(80px);
}

.on {
  display: none;
}

.on,
.off {
  color: white;
  position: absolute;
  transform: translate(-50%, -50%);
  top: 50%;
  left: 50%;
  font-size: 10px;
}

input:checked+.slider .on {
  display: block;
}

input:checked+.slider .off {
  display: none;
}

.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;
}

<body>
  <section id="newsletter">
    <div class="container">
      <h1 id="test1">BUY</h1>
      <form method="post" action="">
        <label class="switch">
    <input type="checkbox" id="togBtn" class="togBtn">
    <div class="slider round">
    <span class="on" name="on" id="on">SELL</span>
    <span class="off" name="off" id="off">BUY</span>
    </div>
    </label>
      </form>
    </div>
    <div class="box">

  </section>
</body>

我添加了切换的变量，用于更改HTML中的名称。该按钮仅适用于两次点击，之后，它再也看不到任何工作了。

Answer 1

变化：

 document.getElementById("test1").style.display="none";

为：

document.getElementById("test1").innerHTML="BUY";

或者，如果您不想更改标题，只需按钮，您可以删除所有的javascript，按钮仍然有效，并在按下时不断更改

Answer 2

你的逻辑有点偏。如果innerHTML为toggle或true，则需要更新false。由于这一行，该元素正在消失：document.getElementById("test1").style.display="none";。在第一次点击时它是true，因此运行代码：document.getElementById("test1").innerHTML="BUY";。在第二次点击toggle等于false时，运行document.getElementById("test1").style.display="none";并删除文本。

将您的脚本更新为此，以便在toggle分别为true或false时更新文本值：

let toggled = true;
togBtn.onclick = function(){
  if(toggled){
   document.getElementById("test1").innerHTML="SELL";
    toggled = false;
  } else  {
    document.getElementById("test1").innerHTML="BUY";
    toggled = true;
  }
};

Answer 3

无需编写这些if条件。你可以在click事件上使用三元运算符来完成它，并像这样更改文本

togBtn.onclick = function() {
var  obj = document.getElementById("test1");
    obj.innerHTML == "BUY"? (obj.innerHTML = "SELL"):(obj.innerHTML = "BUY");
 
};

#newsletter {
  color: #ffffff;
  background: #1d3030;
  height: 60px;
}

#newsletter h1 {
  float: left;
  padding-left: 600px;
}

#newsletter form {
  float: right;
}

.switch {
  position: relative;
  display: inline-block;
  width: 115px;
  height: 34px;
}

.switch input {
  display: none;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #e8491d;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked+.slider {
  background-color: #2196F3;
}

input:focus+.slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked+.slider:before {
  -webkit-transform: translateX(80px);
  -ms-transform: translateX(80px);
  transform: translateX(80px);
}

.on {
  display: none;
}

.on,
.off {
  color: white;
  position: absolute;
  transform: translate(-50%, -50%);
  top: 50%;
  left: 50%;
  font-size: 10px;
}

input:checked+.slider .on {
  display: block;
}

input:checked+.slider .off {
  display: none;
}

.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;

Answer 4

这比制作它简单得多。不需要两个public List<RecommendationImage> translateToRecommendationImages(Recommendation recommendation, List<String> rawImages) throws ServiceException { //try and whatnot for(String image: rawImages){ recommendation.addRecommendationImage(new RecommendationImage(image)); }元素，然后切换每个元素的span。只需使用一个display并根据当前文本的内容更新其文本。

此外，您的HTML无效。您错误地使用了span元素。

label

var btn = document.querySelector(".slider.round");
var output = document.querySelector(".onOff");
var test1 = document.getElementById("test1");
btn.addEventListener("click", function () {
  var text = (output.textContent === "Buy") ? "Sell" : "Buy";
  output.textContent = text;
  test1.textContent = text;
});

#newsletter {
      color: #ffffff;

}

#newsletter h1 {
      float: left;
      padding-left: 600px;
}

#newsletter form {
      float: right;
}

.switch {
      position: relative;
      display: inline-block;
      width: 115px;
      height: 34px;
}

.switch input {
  display: none;
}

.slider {
     position: absolute;
      cursor: pointer;
      top: 0;
      left: 0;
      right: 0;
      bottom: 0;
      background-color: #e8491d;
      -webkit-transition: .4s;
      transition: .4s;
}

    .slider:before {
      position: absolute;
      content: "";
      height: 26px;
      width: 26px;
