如何在两个div之间切换 [英] How to toggle between two divs

问题描述

我试图在两个div之间切换。例如，onload，我希望显示左侧内容，并且正确的内容将保持隐藏状态。如果我单击右侧div，我希望隐藏左侧内容并显示正确的内容，反之亦然。我是javascript的新手，但这就是我所拥有的。我似乎无法让它发挥作用。请帮助...

I am trying to toggle between two divs. For example, onload, I want the left content to show and the right content will remain hidden. If I click the right div, I want the left content to hide and the right content to appear and vise versa. I am very new to javascript but here is what I have. I can't seem to get it to work. Please help...

这是我的HTML代码：

Here is my HTML code:

<div onclick="toggle_visibility('left');">
  Left
</div>

<div onclick="toggle_visibility('right');">
  Right
 </div>


 <div id="left" style="display: block;">
    This is the content for the left side
 <div>

 <div id="right" style="display: none;">
    This is the content for the ride side
 </div>

这是我正在使用的Javascript：

Here is the Javascript I am using:

<script type="text/javascript">
  function toggle_visibility(id) {
     var e = document.getElementById(id);
     if(e.style.display == 'block')
         e.style.display = 'none';
      else
         e.style.display = 'block';
  }
  </script>

推荐答案

现场演示 < a href =http://jsfiddle.net/PauWy/1/ =noreferrer> http://jsfiddle.net/PauWy/1/

HTML：

<p id="toggle">
    <span> Left </span>
    <span> Right </span>
</p>

<div id="left"> LEFT CONTENT </div>
<div id="right"> RIGHT CONTENT </div>

JavaScript：

JavaScript:

$('#toggle > span').click(function() {
    var ix = $(this).index();

    $('#left').toggle( ix === 0 );
    $('#right').toggle( ix === 1 );
});

CSS（隐藏正确的DIV onload）：

CSS (to hide the right DIV onload):

#right { display:none; }

将JavaScript代码放在页面底部。

    <script>
        $(function() {        
            // put jQuery code here    
        });
    </script>    
</body>

注意SCRIPT元素如何位于BODY元素的末尾。另外，请注意jQuery代码应该在ready处理程序中： $（function（）{... code ...}）;

Notice how the SCRIPT element is located at the end of the BODY element. Also, notice that the jQuery code should be inside the ready handler: $(function() { ... code ... });
