Navigation
0

When I click once on one of the options of nav , it works, but if I double click or if I'm in an area and click to go in another area, it gets lost and buga total, I do not know what to do and I've tried using all possible JS.

HTML: 

<nav class="navbar navbar-fixed-top navbar-inverse navbar-transparente ">
      <div class="container">

        <!-- header -->
        <div class="navbar-header">

          <!-- botao toggle -->
          <button type="button" class="navbar-toggle collapsed"
                  data-toggle="collapse" data-target="#barra-navegacao">
            <span class="sr-only">alternar navegação</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>

          <a href="#conteudo-sobre" class="js-scroll-trigger">
            <img src="logopng.png" width="100" height="30" style="margin-top: 10px">
          </a>

        </div>

        <!-- navbar -->
        <div class="collapse navbar-collapse" id="barra-navegacao">
          <ul class="nav navbar-nav navbar-right">
            <li><a id="home" href="#conteudo-home">Home</a></li>
            <li><a id="sobre" href="#conteudo-sobre">Sobre</a></li>
            <li><a id="servicos" href="#conteudo-servicos">Serviços</a></li>
            <li><a id="contato" href="#conteudo-contato">Contato</a></li>
            <li class="divisor" role="separator"></li>
            <li><a id="msc" href="#conteudo-contato">Mande seu currículo</a></li>


          </ul>
        </div>
      </div><!-- /container -->
    </nav><!-- /nav -->

    <div class="capa " id="conteudo-home">

        <div class="texto-capa layer">
        <img src="logopng.png" width="450" height="150" >
        <h4><hr align="center" width="100" size="1">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque vitae pha</h4>
        <a href="#conteudo-sobre" class="btn btn-custom btn-branco btn-lg">Saiba mais</a>

      </div>
    </div>

JQUERY: 

$(document).ready(function(){
    setBindings();
});

function setBindings() {
    $("nav a").click(function(e){
       //e.preventDefault();

        e.preventDefault();

        var sectionID = "conteudo-" + e.currentTarget.id;


        $("html body").animate({
            scrollTop: $("#" + sectionID).offset().top
        }, 1000)

        //alert("-" + e.currentTarget.id);



   //    var sectionID = "conteudo-" e.currentTarget.id;

    //   alert(sectionID + "id");



/*
    $("html body").animate({
        scrollTop: $("#" + sectionID).offset().top

    },1000)

*/
    })

}

You need to make some modifications to your code to make it work. Follow the steps below:

a) Remove the names of href , leave only # : 

<li><a id="home" href="#">Home</a></li>
<li><a id="sobre" href="#">Sobre</a></li>
<li><a id="servicos" href="#">Serviços</a></li>
<li><a id="contato" href="#">Contato</a></li>
<li class="divisor" role="separator"></li>
<li><a id="contato" href="#">Mande seu currículo</a></li>

b) Remove this unnecessary function (do not delete what's inside it): 

function setBindings() {...

Do not forget to delete the key } that closes it.

c) Delete this also calling the above function: 

$(document).ready(function(){
    setBindings();
});

d) Change this line: 

var sectionID = "conteudo-" + e.currentTarget.id;

for 

var sectionID = $(this).attr("id");

e) Replace this: 

$("html body").animate({
    scrollTop: $("#" + sectionID).offset().top
}, 1000)

for this: 

$("html, body").animate({
   scrollTop: $("#conteudo-" + sectionID).offset().top
}, "slow");

With these changes your code should work. 

$("nav a").click(function(e){

   e.preventDefault();

   var sectionID = $(this).attr("id");
   $("html, body").animate({
      scrollTop: $("#conteudo-" + sectionID).offset().top
   }, 1000);

});
