HTML

<ul id="navbar">
    <li><a href="#home" id="nav-home">Home</a></li>
    <li><a href="#portfolio" id="nav-portfolio">Portfolio</a>
        <div class="portfolio-apps">
         <section id="website">
            <span class="button">AAAAAAAAAAAAAAAAAAAAAA</span>
         </section>

    <li><a href="#about" id="nav-about">About Me</a></li>
    <li><a href="#contact" id="nav-contact">Contact</a></li>
   </ul>

JS

$(document).ready(function () {
    var portf_apps = $('.portfolio-apps');
    portf_apps.hide();
    $('#nav-portfolio').click(function() {
        portf_apps.show();
    });
      
});

将你的 Javascript 更改为:

$('#navbar > li > a').click(function(){
    portf_apps.hide();
});
$('#nav-portfolio').unbind('click').click(function() {
    portf_apps.show();
});
