How to show first slide on a jQuery div slider

I am working on a slide with links on each slide that trigger the sliding movement. but I cant figure out how to make the first slide appear on load page, so to make it work I had to make the first slide visible and the others hidden, it's not a real fix, is just so I can keep working on it, so I need to change it

here is the fiddle

http://jsfiddle.net/Paula/XmeGN/10/

Also, I can make it slide to the left instead of the right.

Thank you all for the help!!

HTML

<div id="banner_container" style="min-height:160px; clear:both;">

    <div id="banner_wrapper">
    <div class="banner_panel2" id="target1">

        <a href="#target2" class="banner_panel">Target 2</a><br/>
        <a href="#target3" class="banner_panel">Target 3</a><br/>      
        Target 1
    </div>
    <div class="banner_panel" id="target2">
        <a href="#target1" class="banner_panel">Target 1</a><br/>
        <a href="#target2" class="banner_panel">Target 2</a><br/>

Paula,

  • In the HTML, change class="banner_panel2" to class="banner_panel" and delete the CSS directive for banner_panel2.
  • (optional) Remove CSS directive display:none; from div.banner_panel {...}.
  • Add $("div.banner_panel").eq(0).find('a.banner_panel').eq(0).trigger('click'); after the click handler definition. Adjust one or both of the eq(0) expressions to select any other panel of your choice as the initial panel.

Also, add e.preventDefault(); at the top of the click handler. This inhibits an undesirable effect when a link is clicked that points to the currently active panel.

Javascript should now look like this :

$('a.banner_panel').on('click', function(e) {
    e.preventDefault();
    var $target = $($(this).attr('href')),
        $other = $target.siblings('.active');

    if (!$target.hasClass('active')) {
        $other.removeClass('active').each(function(index, self) {
            var $this = $(this);
            $this.animate({
                left: $this.width()
            }, 500);
        });
        $target.addClass('active').show().css({
            left: -($target.width())
        }).animate({
            left: 0
        }, 500);
    }
});
$("div.banner_panel").eq(0).find('a.banner_panel').eq(0).trigger('click');

DEMO

Users will (probably) see the fly-in effect on page load but maybe that's no bad thing.

Doing it this way ensures that the initial state of the panels is identical to when the user makes a click for him/herself. If, in the future, you change the click handler to do something slightly different then you need to worry less about checking that the HTML/CSS is compatible. Providing everything works fine for user-clicks, then the initial state will also be fine.
