jQuery Menu Selection

Recommended Posts

I have the following.  Depending on which dot in the nav I click on I want it to show as selected.

 

I tried writing my own jQuery to show/hide the different images I'm running into some issues with multiples showing up at the same time.  I'm guessing there is a better method.

 



<div class="dot-nav">
    <a href="#" class="scroll-link" data-id="home" id="home-btn">
        <img src="images/nav-s.png" id="btn-home-s" style="margin-bottom:10px;"/>
        <img src="images/nav-ns.png" id="btn-home-ns" style="margin-bottom:10px;display:none;"/>
    </a><br>
    <a href="#" class="scroll-link" data-id="about" id="about-btn">
        <img src="images/nav-ns.png" id="btn-about-ns" style="margin-bottom:10px;"/>
        <img src="images/nav-s.png" id="btn-about-s" style="margin-bottom:10px;display:none;"/>
    </a><br>
    <a href="#" class="scroll-link" data-id="power" id="power-btn">
        <img src="images/nav-ns.png" id="btn-power-ns" style="margin-bottom:10px;"/>
        <img src="images/nav-s.png" id="btn-power-s" style="margin-bottom:10px;display:none;"/>
    </a><br>
</div>


 



$( "#home-btn" ).click(function() {
                        
                        $( "#btn-home-ns" ).hide(0);
                        $( "#btn-about-s" ).hide(0);
                        $( "#btn-power-s" ).hide(0);
                        $( "#btn-home-s" ).show(0);
                        $( "#btn-about-ns" ).show(0);
                        $( "#btn-power-ns" ).show(0);
  
                    });
$( "#about-btn" ).click(function() {
                        $( "#btn-home-s" ).hide(0);
                        $( "#btn-about-ns" ).hide(0);
                        $( "#btn-power-s" ).hide(0);
                        $( "#btn-home-ns" ).show(0);
                        $( "#btn-about-s" ).show(0);
                        $( "#btn-power-ns" ).show(0);                        
                    });
$( "#power-btn" ).click(function() {
                        $( "#btn-home-s" ).hide(0);
                        $( "#btn-about-s" ).hide(0)
                        $( "#btn-power-ns" ).hide(0);
                        $( "#btn-home-ns" ).show(0);;
                        $( "#btn-about-ns" ).show(0);
                        $( "#btn-power-s" ).show(0);
                    });

Instead of hiding/showing the image files themselves got this working with:

 


 

HTML:

<div class="dot-nav">
    <div class="scroll-link sel" data-id="home" id="home-btn">
      
    </div><br>
    <div class="scroll-link nsel" data-id="about" id="about-btn">
 
    </div><br>
    <div class="scroll-link nsel" data-id="power" id="power-btn">
        
    </div><br>
</div>

 

jQuery:

$( "#home-btn" ).click(function() {
    $( "#home-btn" ).removeClass( "nsel" );
    $( "#home-btn" ).addClass( "sel" );
    
    $( "#about-btn" ).removeClass( "sel" );
    $( "#about-btn" ).addClass( "nsel" );
       
    $( "#power-btn" ).removeClass( "sel" );
    $( "#power-btn" ).addClass( "nsel" );
});
 
$( "#about-btn" ).click(function() {
    $( "#home-btn" ).removeClass( "sel" );
    $( "#home-btn" ).addClass( "nsel" );
    
    $( "#about-btn" ).removeClass( "nsel" );
    $( "#about-btn" ).addClass( "sel" );
    
    
    $( "#power-btn" ).removeClass( "sel" );
    $( "#power-btn" ).addClass( "nsel" );
});
 
$( "#power-btn" ).click(function() {
    $( "#home-btn" ).removeClass( "sel" );
    $( "#home-btn" ).addClass( "nsel" );
    
    $( "#about-btn" ).removeClass( "sel" );
    $( "#about-btn" ).addClass( "nsel" );  
    
    $( "#power-btn" ).removeClass( "nsel" );
    $( "#power-btn" ).addClass( "sel" );
});

 

CSS:

.dot-nav
{background:#000;}
 
.sel{
    background:url('images/nav-s.png') no-repeat;
    width:21px;
}
 
.nsel{
    background:url('images/nav-ns.png') no-repeat;
    width:21px;
}
 
#home-btn,#about-btn,#power-btn{
    width:21px;
    height:21px;
}

 

This is fine and works, but is there a better practice or method?
