How to Add Auto-Rotation to a jQuery Horizontal Accordion

问题

I've built a horizontal accordion that animates on click. I want to add auto-rotating functionality to it so the slides will rotate by themselves every three seconds but i cannot figure this part out...

Here is the code for the Horizontal Accordion:

<div id="slideshow">
<ol id="slides">
    <li class="slide open active" id="slide-1">
        <a href="recipe_detail.aspx?did=1014"><img src="media/images/recipes/featured-tuna-chop-chop-salad.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
    <li class="slide open" id="slide-2">
        <a href="recipe_detail.aspx?did=1016"><img src="media/images/recipes/featured-tuna-rolls-with-GS-sauce.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
    <li class="slide open" id="slide-3">
        <a href="recipe_detail.aspx?did=1101"><img src="media/images/recipes/featured-salmon-breakfast-strudel.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
    <li class="slide open" id="slide-4">
        <a href="recipe_detail.aspx?did=775"><img src="media/images/recipes/featured-chunky-tuna-potato-salad.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
    <li class="slide open" id="slide-5">
        <a href="recipe_detail.aspx?did=988"><img src="media/images/recipes/featured-clam-and-artichoke-mini.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
    <li class="slide open" id="slide-6">
        <a href="recipe_detail.aspx?did=598"><img src="media/images/recipes/featured-salmon-party-app.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
    <li class="slide open" id="slide-7">
        <a href="recipe_detail.aspx?did=425"><img src="media/images/recipes/featured-tortellini-tuna-salad.jpg" alt="" /></a>
        <a class="slidebutton" href="javascript:void(0);"></a>
    </li>
</ol>
<ol id="slidecontents">
    <li class="slidecontent open" id="content-slide-1">
        <p><span class="featureRecipeTitle">Stir Fried &ldquo;Chop Chop&rdquo; Salad</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=1014"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
    <li class="slidecontent" id="content-slide-2">
        <p><span class="featureRecipeTitle">Tuna Rolls with Fresh Ginger Dipping Sauce</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=1016"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
    <li class="slidecontent" id="content-slide-3">
        <p><span class="featureRecipeTitle">Mermaid's Breakfast Strudel</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=1101"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
    <li class="slidecontent" id="content-slide-4">
        <p><span class="featureRecipeTitle">Chunky Tuna Potato Salad</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=775"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
    <li class="slidecontent" id="content-slide-5">
        <p><span class="featureRecipeTitle">Clam &amp; Artichoke Mini Melts</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=988"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
    <li class="slidecontent" id="content-slide-6">
        <p><span class="featureRecipeTitle">Salmon Party Spread Appetizer</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=598"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
    <li class="slidecontent" id="content-slide-7">
        <p><span class="featureRecipeTitle">Tortellini Tuna Salad</span></p>
        <div class="recipeSliderGetRecipe"><a href="recipe_detail.aspx?did=425"><img src="media/images/recipes/button-get-the-recipe.png"></a></div>
    </li>
</ol>

Here is the javascript affiliated with it:

$(document).ready(function() {
    $('#nav li').hover(function() {
        $(this).addClass('hover');
    }, function() {
        $(this).removeClass('hover');
    });

    $('.slide')
        .bind('open', function() {
            if(! $(this).hasClass('open')) {
                $(this).next().trigger('open');
                $(this).addClass('open');
                $(this).animate({right: "-=423px"});
            } else {
                $(this).prev().trigger('close');
            }
            $(this).siblings().removeClass('active');
            $(this).addClass('active');
        })
        .bind('close', function() {
            if($(this).hasClass('open')) {
                $(this).removeClass('open');
                $(this).animate({right: "+=423px"});
                $(this).prev().trigger('close');
            }
        });

    $('.slidebutton').click(function() {
        $(this).parent().trigger('open');
        $('#content-' + $(this).parent().attr('id')).trigger('show');
    });

    $('.slidecontent').bind('show', function() {
        $('.slidecontent').removeClass('open');
        $(this).addClass('open');
    });

    $('#nav>li').hover(function() {
        $(this).addClass('hover');
    }, function() {
        $(this).removeClass('hover');
    });
});

If anybody has some wisdom for me to make the slides auto-rotate every 3 seconds that would be amazing. Thank You!

回答1:

First - I don't feel the way You use prev().trigger('something') I'm not sure what it's for. It looks like it populates the event to other elements. I don't get it ;)

As for the question: You should do something like this:

setInterval(function(){
 $next=$('.active').next('.slide');
 if($next.length==0){ $next=$('.slide:first'); }
 $next.find('.slidebutton').triggerHandler('click');
},3000);

You might need to change some classes etc.
