弹出 HTML：单击按钮时不显示内容

Question

点击时不显示弹出内容。 我只会放置代码的缩短版本。 单击按钮时，应显示内容。 html 按钮将触发 js 代码以将 css 设置为活动状态。 CSS 将显示弹出窗口的活动版本，使其可见。

function togglePopup() {
  document.getElementById("popup_chicken").classList.toggle("active");
}

.chicken {
    background: rgb(0, 0, 0, 0.5);
    width: 100%;
    height: auto;
    text-align: center;
    z-index: 2;
    transform: translate(-50%, -50%) scale(0);
    visibility: hidden;
    &_content {
        display: inline-block;
        background-color: black;
        border-radius: 30px;
        box-shadow: -5px 5px 10px black;
        padding: 20px;
        width: 80%;
        margin-top: 3%;
        margin-bottom: 3%;
        &_buttons {
        margin: 15px 0;
        &_close {
            background-color: $b;
            cursor: pointer;
            border-radius: 50px;
            border-style: hidden;
            padding: 20px 30px;
            margin: 0 25px;
    }
    .chicken.active .chicken {
        transform: translate(-50%, -50%) scale(1);
        transition: all 300ms ease-in-out;
        visibility: visible;
    }
}

<button onclick="togglePopup()">
click me!
</button>

<div class="chicken" id="popup_chicken">
  <div class="chicken_content">
    content here
    <button class="chicken_buttons_close" onclick="togglePopup()">Close</button>
   </div>
</div>

Answer 1

我不确定这是否是你想要的，但你可以尝试一下；

function togglePopup() {
  var element = document.getElementById("trt2");
  element.classList.toggle("mystyle");
}

.mystyle {
        transform: translate(-50%, -50%) scale(1);
        transition: all 300ms ease-in-out;
        visibility: visible;
    }

<button onclick="togglePopup()">click me!</button>

<div class="chicken" id="trt2">
  <div class="chicken_content" id="trt">
    content here
    <button class="chicken_buttons_close" onclick="togglePopup()">Close</button>
   </div>
</div>
