Wie kann ich die Sidebar standardmäßig im Bootstrap ausblenden?

Ich habe hier eine großartige Referenz als Seitenleiste für Bootstrap beim Entwerfen von Webformularanwendungen: http://startbootstrap.com/template-overviews/simple-sidebar/

und hier ist der Code:

<!DOCTYPE html>
<html lang="en">

<head>

    <div id="wrapper">

        <!-- Sidebar -->
        <div id="sidebar-wrapper">
            <ul class="sidebar-nav">
                <li class="sidebar-brand">

    });
    </script>

</body>

</html>

Wie blende ich die Seitenleisten-Navigation zuerst aus, indem Sie jquery verwenden, wenn die Seite geladen wird, und die Seitenleiste nur angezeigt wird, wenn die Schaltfläche auf "Menü wechseln" geklickt wird. Die Seitenleiste in diesem Code wird angezeigt, wenn die Seite geladen wird.

Hier ist die Jquery-Funktion zum Umschalten:

<!-- Menu Toggle Script -->
<script>
  $("#menu-toggle").click(function(e) {
    e.preventDefault();
    $("#wrapper").toggleClass("toggled");
  });
</script>

Veränderung

<div id="wrapper">

zu

<div id="wrapper" class="toggled">

das heißt, Sie sagen der Seitenleiste, dass sie standardmäßig ausgeblendet werden sollen.


Ausgabe:

$("#menu-toggle").click(function(e) {
  e.preventDefault();
  $("#wrapper").toggleClass("toggled");
});

Wenn die Seite fertig geladen ist, müssen Sie die Seitenleiste umschalten

Jquery unterstützt es:

$( document ).ready(function() {
    $("#wrapper").toggleClass("toggle");
});

Fügen Sie zunächst die umgeschaltete Klasse zum Seitenleisten-Wrapper hinzu. So wird es zunächst in verborgenem Zustand sein. Wenn Sie auf die Menüumschaltung klicken, funktioniert es wie gewohnt.

<div id="sidebar-wrapper" class="toggled">

Probieren Sie mal das hier an 

HTML Quelltext:

<div class="container">
<div class="row">
    <div id="colPush" class="span0"></div>
    <div id="colMain" class="span12">
        <a id="trig" class="btn btn-inverse">Sidebar Toggle</a>
    </div>

  </div>
</div>

Css-Code:

.row div {
    height: 200px;
    -webkit-transition: width 0.3s ease, margin 0.3s ease;
    -moz-transition: width 0.3s ease, margin 0.3s ease;
    -o-transition: width 0.3s ease, margin 0.3s ease;
    transition: width 0.3s ease, margin 0.3s ease;
}

.span0 {
    width: 0;
    margin-left: 0;
}

#colPush {
    background-color: #A6BFBA;
}

#colMain {
    background-color: #DE4124;
}

#trig {
    margin: 50px;
}

.row div + div {
    margin-left: 0;
}

jQuery-Code:

$('#trig').on('click', function () {
    $('#colMain').toggleClass('span12 span9');
    $('#colPush').toggleClass('span0 span3');
});
