Question

我正在尝试在左侧实施导航侧边栏，其中包含链接列表（<a>），这样点击每个链接时，相应的<div>将会加载到右侧。

我在onclick中拥有<a>属性的功能时。它在浏览器控制台上给我错误。

未捕获的ReferenceError：未定义callFunction

这是我的实施：

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
	function callFunction(){alert("Load divs");}
});
</script>

<style>
div.container {
    width: 100%;
    border: 1px solid gray;
}

header, footer {
    padding: 1em;
    color: white;
    background-color: powderblue;
    clear: left;
    text-align: center;
}

nav {
    float: left;
    max-width: 160px;
    margin: 0;
    padding: 1em;
}

nav ul {
    list-style-type: none;
    padding: 0;
}
   
nav ul a {
    text-decoration: none;
}

article {
    margin-left: 170px;
    border-left: 1px solid gray;
    padding: 1em;
    overflow: hidden;
}
</style>
</head>
<body>

<div class="container">

<header>
   <h1>My Company</h1>
</header>
  
<nav>
  <ul>
    <li><a href="#" onclick="callFunction()">Link1</a></li>
    <li><a href="#" onclick="callFunction()">Link2</a></li>
    <li><a href="#" onclick="callFunction()">Link3</a></li>
  </ul>
</nav>

<!--<div id="Link1" class="class1">
	<h1>Link1</h1>
	<p>Link1 detail</p>
</div>

<div id="Link2" class="class1">
	<h1>Link2</h1>
	<p>Link2 detail</p>
</div>-->

<footer>Copyright &copy; myCompany</footer>

</div>

</body>
</html>

我的要求是有一个Links和s的列表，其中s应该被隐藏，并且只有在点击相应的链接时才会出现。

Answer 1

以下是适合您的代码。

<div>未呈现/显示。
点击链接（<a>）后，会显示相应的<div>
维护导航侧栏。

Answer 2

您不需要在callFunction()状态上调用$(document).ready，因为只有在加载页面时才会调用它，并且在文档准备好/加载时，会抛出错误。因此，将定义置于$(document).ready之外。

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
function callFunction(){alert("Load divs");}
</script>

<style>
div.container {
    width: 100%;
    border: 1px solid gray;
}

header, footer {
    padding: 1em;
    color: white;
    background-color: powderblue;
    clear: left;
    text-align: center;
}

nav {
    float: left;
    max-width: 160px;
    margin: 0;
    padding: 1em;
}

nav ul {
    list-style-type: none;
    padding: 0;
}
   
nav ul a {
    text-decoration: none;
}

article {
    margin-left: 170px;
    border-left: 1px solid gray;
    padding: 1em;
    overflow: hidden;
}
</style>
</head>
<body>

<div class="container">

<header>
   <h1>My Company</h1>
</header>
  
<nav>
  <ul>
    <li><a href="#" onclick="callFunction()">Link1</a></li>
    <li><a href="#" onclick="callFunction()">Link2</a></li>
    <li><a href="#" onclick="callFunction()">Link3</a></li>
  </ul>
</nav>

<!--<div id="Link1" class="class1">
	<h1>Link1</h1>
	<p>Link1 detail</p>
</div>

<div id="Link2" class="class1">
	<h1>Link2</h1>
	<p>Link2 detail</p>
</div>-->

<footer>Copyright &copy; myCompany</footer>

</div>
