照常构建菜单，即

<ul id="menu">
    <li><a href="about-us.html">About Us</a>
    <li><a href="services.html">Services</a>
    <li><a href="products.html">Products</a>
</ul>

以及内容的占位符.

<div id="content"></div>

然后运行类似这样的代码

$("#menu li a").click(function(e) {
    // prevent from going to the page
    e.preventDefault();

    // get the href
    var href = $(this).attr("href");
    $("#content").load(href, function() {
        // do something after content has been loaded
    });
});
