JavaScript show/hide tab

问题

What i want is hide all content first, then click one tab, the corresponding content shows (the tab becomes 'active'), where click it again it will disappear. some of the tabs are just a 'mailto' link.

problem is i can't hide the tabs when click again

    $(document).ready(function(){
    $('#nav div').hide();
    $('#nav div:first').show();
    $('#nav ul li:first').addClass('active');
    $('#nav ul li a').click(function(){ 
        $('#nav div').hide();
        $('#nav ul li').removeClass('active');
        $(this).parent().addClass('active'); 
        var currentTab = $(this).attr('href'); 
        if($(currentTab).css('display')=='none'){
            $(currentTab).show();
        }else{
            $(currentTab).hide();
        }

    }
);
});

the navigation code is the following:

<div id="nav">
    <ul>
      <li><a href="#about">About</a></li>
      <li><a href="mailto:email">Email</a></li>
      <li><a href="#contact">Contact</a></li>
    </ul>
    <div id="about">
      about
    </div>
    <div id="contact">
      contact
    </div>
</div>

This should work:

$(function() {
    $('#nav div').hide();
    $('#nav div:first').show();
    $('#nav ul li:first').addClass('active');
    $('#nav ul li a').click(function(){
        var currentTab = $(this).attr('href');
        var vis = $(currentTab).is(':visible');
        $('#nav div').hide();
        $('#nav ul li').removeClass('active');
        $(this).parent().addClass('active');
        if(vis) {
            $(currentTab).hide();
        } else {
            $(currentTab).show();
        }
    });
});

you have to check if the current tab is visible before you hide it.

   $(document).ready(function(){
$('#nav div').hide();
$('#nav div:first').show();
$('a').click(function(){    
    var currentTab = '#'+$(this).text().toLowerCase();
    if($(currentTab).is(':visible')){
        $('#nav div').hide();
        $(currentTab).hide();
    }else{
        $('#nav div').hide();
        $(currentTab).show();
    }
}
);
});


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

Please try above code.. I change href value to just "#" then some change in jquery. Please ask in comment if you have any doubt.. click here to test

Change the click function to:

$('#nav ul li a').click(function(){ 
    var currentTab = $(this).attr('href');  
    $('#nav div').not(currentTab).hide();
    $('#nav ul li').removeClass('active');
    $(this).parent().toggleClass('active');     
    if (currentTab.indexOf("mailto:") === -1)
    {
        $(currentTab).toggle();
    }
});
