Jquery滑块下一个/上一个按钮

Question

我已经构建了一个滑块，可以单击图像并向前移动。我正在尝试添加Next和Previous按钮，但遇到了麻烦。任何帮助表示赞赏！

下面是我在哪里演示... JSFiddle

<div id="container"> 

    <div class="next">Next</div> 
    <div class="prev">Previous</div> 

    <div id="image1" class="box">Orange</div> 
    <div id="image2" class="box">Blue</div> 
    <div id="image3" class="box">Green</div> 
    <div id="image4" class="box">Red</div> 
    <div id="image5" class="box">Yellow</div> 

</div> 

CSS

body { 
    padding: 0px;  
} 

.next { 
    width:100px; 
    height:50px; 
} 

.prev { 
    width:100px; 
    height:50px; 
} 

#container { 
    position: absolute; 
    margin: 0px; 
    padding: 0px; 
    width: 100%; 
    height: 100%; 
    overflow: hidden; 

} 

.box { 
    position: absolute; 
    width: 50%; 
    height: 300px; 
    line-height: 300px; 
    font-size: 50px; 
    text-align: center; 
    left: 150%; 
    top: 100px; 
    margin-left: -25%; 
} 

#image1 { 
    background-color: orange; 
    left: 50%; 
} 

#image2 { 
    background-color: blue; 
} 

#image3 { 
    background-color: green; 
} 

#image4 { 
    background-color: red; 
} 

#image5 { 
    background-color: yellow; 
} 

JQUERY

$('.box').click(function() { 

$(this).animate({ 
    left: '-50%' 
}, 500, function() { 
    $(this).css('left', '150%'); 
    $(this).appendTo('#container'); 
}); 

$(this).next().animate({ 
    left: '50%' 
}, 500); 
});​

嘿检查THI s一出：http://jsfiddle.net/Dwxfc/

这应该适合您的需要，:)也注意上面的示例只有下一个功能，因此它重复自己。

休息希望它适合您的需要，请lemme知道这是否。 B-)

代码

$(function(){ 

    //Lazyload function 
    $.fn.lazyload = function(){ 
     var image = $(this); 
     if (image.attr('real-src')){ 
      image.attr('src', image.attr('real-src')); 
      image.removeAttr('real-src'); 
     } 
     return this; 
    }; 

    //Slider constructor 
    $.fn.imageSlider = function(){ 
     this.each(function(){ 
      var $slider = $(this); 

      var $active = $slider.find('img:first'); 
      $active.addClass('active'); 
      $active.lazyload(); 

      //Slider control buttons 
      var $nextButton = $slider.find('.next'); 
      var $prevButton = $slider.find('.previous'); 

      $prevButton.toggle(); 

      //Handle if next button should appear 
      $nextButton.click(function(){ 
       var $next = $active.next(); 
       $active.removeClass('active'); 
       $next.addClass('active'); 
       $active = $next; 
       $active.lazyload(); 

       if ($active.next().length == 0){ 
        $nextButton.toggle(); 
       } 
       $prevButton.show(); 

      }) 

      //Handle if next button should appear 
      $prevButton.click(function(){ 
       var $prev = $active.prev(); 
       $active.removeClass('active'); 
       $prev.addClass('active'); 
       $active = $prev; 
       $active.lazyload(); 

       if ($active.prev().length == 0){ 
        $prevButton.toggle(); 
       } 
       $nextButton.show(); 
      }) 
     }) 

      return this; 
     }; 

}) 

$(document).ready(function(){ 
    var $slider = $('#slider'); 
    if ($slider.find('.active').length == 0){ 
     $slider.imageSlider(); 
    } 
})
