Reload a section of page without page refresh

    Hi all,

    I am attempting to reload a section (div) of page without refreshing the entire page.

    This is the index.html file - 

    
<html>
<body>
<head>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>

<ul>
<li><a href="">Main</a></li>
<li><a id="second" href="">Second</a></li>
<li><a id="third" href="">Third</a></li>
<li><a id="fourth" href="">Fourth</a></li>
</ul>

<div id="main">
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing 
software like Aldus PageMaker including versions of Lorem Ipsum.</p>
</div>


<script>
$(document).ready(function() {
    $("a#second").click(function(e) {
        e.preventDefault();
        $("#main").load("refresh.html #alternate");
    })
     $("a#third").click(function(e) {
        e.preventDefault();
        $("#main").load("refresh.html #alternate2");
    })
     $("a#fourth").click(function(e) {
        e.preventDefault();
        $("#main").load("refresh.html #alternate3");
    })
   });
</script>

</body>
</html>
    Code (markup):
    And this is the refresh.html code -

    <div id="alternate">
<p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum,
"Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.</p>
</div>

<div id="alternate2">
<p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident,
sometimes on purpose (injected humour and the like).</p>
</div>

<div id="alternate3">
<p>Last one.</p>
</div>
    Code (markup):
    I wanted to keep the other div in the same index.html file. But unsure of how to do that.

    Is this the most efficient way of doing it? Loading might be fast in this example as there ain't much codes. What if the site grows bigger?

    Thanks in advance!

    Why don't you slice refresh.html into several files so they could be loaded into each individual section.

    My lazy version:
    
<html>
<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
</head>
<body>
    <a href='#' id=second role=button>Click</a>
    <div id=main> Original data </div>
    <script>
        $( "a#second" ).click(function(e) {
            e.preventDefault();
            $( "#main" ).load( "refresh.html" );
        });
    </script>
</body>
</html>
    Code (markup):
    If you think that was a terrible idea you could do it with .search() function to sort out data and pick one you want, but good luck with that.
