單擊錨點以顯示下面隱藏的 div，然后隱藏所有其他內容 div？

Question

我創建了 4 個容器，可以單擊它們以顯示下面的內容。 我想一次只顯示一個隱藏的 div。 因此，如果用戶單擊另一個容器，則所有其他容器都將被隱藏。 當前，一旦單擊它們，我就無法隱藏任何容器。 我真的很感激任何幫助:)

JS

function toggle_visibility(id) {
  var e = document.getElementById(id);
  if(e.style.display == 'none')
     e.style.display = 'block';
  else
     e.style.display = 'none';
}

CSS

html, body { height: 100%; padding: 0 ; margin: 0; }
a { width: 100%; height: 100%; color: #000; display: block; position: absolute; background: #647070; }
.section { width: 49.9%; height: 49.9%; float: left; position: relative; overflow: hidden; }
#div1, #div3 { border-right: 1px solid black; }
#div3, #div4 { border-top: 1px solid black; }

HTML

  <div id="div1" class="section">
    <div id="festival">
      <a href="#" onclick="toggle_visibility('festival');" style="">Festival&trade;</a>
    </div>
     <p>This is the content of Q1</p>
  </div>

  <div id="div2" class="section">
    <div id="register">
      <a href="#" onclick="toggle_visibility('register');" style="">Register</a>
    </div>
    <p>This is the content of Q2</p>
  </div>

  <div id="div3" class="section">
    <div id="connect">
      <a href="#" onclick="toggle_visibility('connect');" style="">Connect</a>
    </div>
    <p>This is the Q3 content.</p>
  </div>

  <div id="div4" class="section">
    <div id="forth">
      <a href="#" onclick="toggle_visibility('forth');" style="">Forth</a>
    </div>
    <p>This is the Q4 content.</p>
  </div> 

Answer 1

您可以添加如下內容：

var divsToHide = document.querySelectorAll(".section > div")
for (var i = 0; i < divsToHide.length; i++) {
  divsToHide[i].style.display = "block";
}

這將遍歷每個.section並顯示它的直接 div。

演示

 function toggle_visibility(id) { var divsToHide = document.querySelectorAll(".section > div") for (var i = 0; i < divsToHide.length; i++) { divsToHide[i].style.display = "block"; } var e = document.getElementById(id); if (e.style.display == 'none') e.style.display = 'block'; else e.style.display = 'none'; }

 html, body { height: 100%; padding: 0; margin: 0; } a { width: 100%; height: 100%; color: #000; display: block; position: absolute; background: #647070; }.section { width: 49.9%; height: 49.9%; float: left; position: relative; overflow: hidden; } #div1, #div3 { border-right: 1px solid black; } #div3, #div4 { border-top: 1px solid black; }
