Impossibile leggere proprietà 'left' di indefinito

Question

Cercando di capire il motivo per cui Chrome sta gettando fuori errore

"Uncaught TypeError: Cannot read property 'left' of undefined"

anche se #explorenav grandi opere, ma #experiencenav non sembra funzionare. mi sto perdendo qualcosa?

JS CODICE: CODE

$('.nav li#explorenav a').click(function(){ 
    $('body').animate({scrollLeft: $("#explore").offset().left-15}, 1000, function(){ 
     $(this).parent().addClass('active'); 
    }); 

    return false; 
}); 

$('.nav li#experiencenav a').click(function(){ 
    $('body').animate({scrollLeft: $("#experience").offset().left-15}, 1200, function(){ 
     $(this).parent().addClass('active'); 
    }); 

    return false; 
});

Answer 1

Nello script sul sito che hai questo codice:

$('.nav li#experiencenav a').click(function(){ 
    $('body').animate({scrollLeft: $("#experience .EmptyPage").offset().left-20}, 1200, function(){ 
     $(this).parent().addClass('active'); 
     $('li#homenav, li#discovernav, li#explorenav, li#downloadnav').removeClass('active'); 
    }); 
     return false; 
    }); 

e non riesce a trovare elemento $("#experience .EmptyPage"). Ma avete div all'interno del vostro #explore div che ha questo div:

<div class="EmptyPage"> 
&nbsp; 
</div> 

Ecco perché il codice sta lavorando per esplorare collegamento, ma non per altri collegamenti.
