jq图片切换特效

首先引入js，内容如下：

(function($){$.fn.slides=function(option){option=$.extend({},$.fn.slides.option,option);return this.each(function(){$('.'+option.container,$(this)).children().wrapAll('<div class="slides_control"/>');var elem=$(this),control=$('.slides_control',elem),total=control.children().size(),width=control.children().outerWidth(),height=control.children().outerHeight(),start=option.start-1,effect=option.effect.indexOf(',')<0?option.effect:option.effect.replace(' ','').split(',')[0],paginationEffect=option.effect.indexOf(',')<0?effect:option.effect.replace(' ','').split(',')[1],next=0,prev=0,number=0,current=0,loaded,active,clicked,position,direction;if(total<2){return;}
if(start<0){start=0;};if(start>total){start=total-1;};if(option.start){current=start;};if(option.randomize){control.randomize();}
$('.'+option.container,elem).css({overflow:'hidden',position:'relative'});control.css({position:'relative',(width*3),height:height,left:-width});control.children().css({position:'absolute',top:0,left:width,zIndex:0,display:'none'});if(option.autoHeight){control.animate({height:control.children(':eq('+start+')').outerHeight()},option.autoHeightSpeed);}
if(option.preload&&control.children()[0].tagName=='IMG'){elem.css({background:'url('+option.preloadImage+') no-repeat 50% 50%'});var img=$('img:eq('+start+')',elem).attr('src')+'?'+(new Date()).getTime();$('img:eq('+start+')',elem).attr('src',img).load(function(){$(this).fadeIn(option.fadeSpeed,function(){$(this).css({zIndex:5});elem.css({background:''});loaded=true;});});}else{control.children(':eq('+start+')').fadeIn(option.fadeSpeed,function(){loaded=true;});}
if(option.bigTarget){control.children().css({cursor:'pointer'});control.children().click(function(){animate('next',effect);return false;});}
if(option.hoverPause&&option.play){control.children().bind('mouseover',function(){stop();});control.children().bind('mouseleave',function(){pause();});}
if(option.generateNextPrev){$('.'+option.container,elem).after('<a href="#" class="'+option.prev+'">Prev</a>');$('.'+option.prev,elem).after('<a href="#" class="'+option.next+'">Next</a>');}
$('.'+option.next,elem).click(function(e){e.preventDefault();if(option.play){pause();};animate('next',effect);});$('.'+option.prev,elem).click(function(e){e.preventDefault();if(option.play){pause();};animate('prev',effect);});if(option.generatePagination){elem.append('<ul class='+option.paginationClass+'></ul>');control.children().each(function(){$('.'+option.paginationClass,elem).append('<li><a rel='+number+' href="#">'+(number+1)+'</a></li>');number++;});}else{$('.'+option.paginationClass+' li a',elem).each(function(){$(this).attr('rel',number);number++;});}
$('.'+option.paginationClass+' li a:eq('+start+')',elem).parent().addClass('current');$('.'+option.paginationClass+' li a',elem).click(function(){if(option.play){pause();};clicked=$(this).attr('rel');if(current!=clicked){animate('pagination',paginationEffect,clicked);}
return false;});if(option.play){playInterval=setInterval(function(){animate('next',effect);},option.play);elem.data('interval',playInterval);};function stop(){clearInterval(elem.data('interval'));};function pause(){if(option.pause){clearTimeout(elem.data('pause'));clearInterval(elem.data('interval'));pauseTimeout=setTimeout(function(){clearTimeout(elem.data('pause'));playInterval=setInterval(function(){animate("next",effect);},option.play);elem.data('interval',playInterval);},option.pause);elem.data('pause',pauseTimeout);}else{stop();}};function animate(direction,effect,clicked){if(!active&&loaded){active=true;switch(direction){case'next':prev=current;next=current+1;next=total===next?0:next;position=width*2;direction=-width*2;current=next;break;case'prev':prev=current;next=current-1;next=next===-1?total-1:next;position=0;direction=0;current=next;break;case'pagination':next=parseInt(clicked,10);prev=$('.'+option.paginationClass+' li.current a',elem).attr('rel');if(next>prev){position=width*2;direction=-width*2;}else{position=0;direction=0;}
current=next;break;}
if(effect==='fade'){option.animationStart();if(option.crossfade){control.children(':eq('+next+')',elem).css({zIndex:10}).fadeIn(option.fadeSpeed,function(){control.children(':eq('+prev+')',elem).css({display:'none',zIndex:0});$(this).css({zIndex:0});option.animationComplete(next+1);active=false;});}else{option.animationStart();control.children(':eq('+prev+')',elem).fadeOut(option.fadeSpeed,function(){if(option.autoHeight){control.animate({height:control.children(':eq('+next+')',elem).outerHeight()},option.autoHeightSpeed,function(){control.children(':eq('+next+')',elem).fadeIn(option.fadeSpeed);});}else{control.children(':eq('+next+')',elem).fadeIn(option.fadeSpeed,function(){if($.browser.msie){$(this).get(0).style.removeAttribute('filter');}});}
option.animationComplete(next+1);active=false;});}}else{control.children(':eq('+next+')').css({left:position,display:'block'});if(option.autoHeight){option.animationStart();control.animate({left:direction,height:control.children(':eq('+next+')').outerHeight()},option.slideSpeed,function(){control.css({left:-width});control.children(':eq('+next+')').css({left:width,zIndex:5});control.children(':eq('+prev+')').css({left:width,display:'none',zIndex:0});option.animationComplete(next+1);active=false;});}else{option.animationStart();control.animate({left:direction},option.slideSpeed,function(){control.css({left:-width});control.children(':eq('+next+')').css({left:width,zIndex:5});control.children(':eq('+prev+')').css({left:width,display:'none',zIndex:0});option.animationComplete(next+1);active=false;});}}
if(option.pagination){$('.'+option.paginationClass+' li.current',elem).removeClass('current');$('.'+option.paginationClass+' li a:eq('+next+')',elem).parent().addClass('current');}}};});};$.fn.slides.option={preload:false,preloadImage:'/img/loading.gif',container:'slides_container',generateNextPrev:false,next:'next',prev:'prev',pagination:true,generatePagination:true,paginationClass:'pagination',fadeSpeed:350,slideSpeed:350,start:1,effect:'slide',crossfade:false,randomize:false,play:0,pause:0,hoverPause:false,autoHeight:false,autoHeightSpeed:350,bigTarget:false,animationStart:function(){},animationComplete:function(){}};$.fn.randomize=function(callback){function randomizeOrder(){return(Math.round(Math.random())-0.5);}
return($(this).each(function(){var $this=$(this);var $children=$this.children();var childCount=$children.length;if(childCount>1){$children.hide();var indices=[];for(i=0;i<childCount;i++){indices[indices.length]=i;}
indices=indices.sort(randomizeOrder);$.each(indices,function(j,k){var $child=$children.eq(k);var $clone=$child.clone(true);$clone.show().appendTo($this);if(callback!==undefined){callback($child,$clone);}
$child.remove();});}}));};})(jQuery);

其次html代码：

<div id="container-img">
        <div id="example">
            
            <div id="slides">
            <div class="info" title=""></div>
                <div class="slides_container">
                    <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-1.jpg" width="570" height="270" alt="1"></a>
                    <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-2.jpg" width="570" height="270" alt="2"></a>
                    <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-3.jpg" width="570" height="270" alt="3"></a>
                    <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-4.jpg" width="570" height="270" alt="4"></a>
                    <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-5.jpg" width="570" height="270" alt="5"></a>
                </div>
                <a href="#" class="prev"><img src="__ROOT__/Public/showimages/img/arrow-prev.png" width="24" height="43" alt="Arrow Prev"></a>
                <a href="#" class="next"><img src="__ROOT__/Public/showimages/img/arrow-next.png" width="24" height="43" alt="Arrow Next"></a>
            </div>
            

然后上css：

/* 
    Resets defualt browser settings
    reset.css
*/
html,body,div,span,applet,object,iframe,h1,h2,h3,h4,h5,h6,p,blockquote,pre,a,abbr,acronym,address,big,cite,code,del,dfn,em,font,img,ins,kbd,q,s,samp,small,strike,strong,sub,sup,tt,var,dl,dt,dd,ol,ul,li,fieldset,form,label,legend,table,caption,tbody,tfoot,thead,tr,th,td { margin:0; padding:0; border:0; outline:0; font-weight:inherit; font-style:inherit; font-size:100%; font-family:inherit; vertical-align:baseline; }
:focus { outline:0; }
a:active { outline:none; }
body {font-family: '微软雅黑'; font-size: 14px;}
ol,ul { list-style:none; }
table { border-collapse:separate; border-spacing:0; }
caption,th,td { text-align:left; font-weight:normal; }
blockquote:before,blockquote:after,q:before,q:after { content:""; }
blockquote,q { quotes:"" ""; }


#container {
    width:400px;
    padding:0px;
    margin:0 auto;
    position:relative;
    z-index:0;
}

#example {
    width:400px;
    height:270px;
    position:relative;
}

#ribbon {
    position:absolute;
    top:-3px;
    left:-3px;
    z-index:500;
}

#frame {
    position:absolute;
    z-index:0;
    width:450px;
    height:341px;
    top:-3px;
    left:00px;
}

#slides {
    position:absolute;
    top:0px;
    left:0px;
    z-index:100;
}

#slides .next,#slides .prev {
    position:absolute;
    top:107px;
    left:0px;
    width:24px;
    height:43px;
    display: none;
    
    
    
}
#slides .next:hover,#slides .prev:hover{
    display: block!important;
    z-index:101;
} 
.slides_show{
    display: block!important;
    z-index:101;
}

.slides_container {
    width:400px;
    height:270px;
    overflow:hidden;
    position:relative;
    box-shadow: 0 0 10px #888;
}
.slides_container a:hover{opacity: 1;} 
.info{text-indent: 2em;position: absolute; width: 400px;margin-top: 270px;height: 50px;transition:background 1s,margin-top 0.5s,font-size 0.2s;z-index: 200;}
.info:hover{margin-top: 230px;color: #fff;}   
.infoadd{background: rgba(0, 0, 0, 0.2) !important; /* IE无效，FF有效 */

            background: #fff;color: #fff;text-shadow:0 0 1px #888;

            filter: alpha(opacity=60);margin-top: 230px;display:inline;}
#slides .next {
    left:375px;

}

.pagination {
    margin:0px auto 0;
    width:100px;
    
}

.pagination li {
    float:left;
    margin:0 1px;
}

.pagination li a {
    display:block;
    width:12px;
    height:0;
    padding-top:12px;
    background-image:url(../img/pagination.png);
    background-position:0 0;
    float:left;
    overflow:hidden;
}

.pagination li.current a {
    background-position:0 -12px;
}

a:link,a:visited {
    color:#599100;
    text-decoration:none;
}

a:hover,a:active {
    color:#599100;
}

最后加上jq鼠标经过图像显示文字效果：

$(function(){
        $('#slides').slides({
            preload: true,
            preloadImage: 'img/loading.gif',
            play: 5000,
            pause: 2500,
            hoverPause: true
        });

        setInterval('change()',100);
        $(".slides_container").find('img').live('mouseover',function(){
            b=$(this).attr('alt');
            $('.info').addClass('infoadd');    
            $('.next').addClass('slides_show');
            $('.prev').addClass('slides_show');                    
            //alert(r);
            $(this).attr('title',text);

        })
        $(".slides_container").find('img').live('mouseout',function(){
            $(".info").removeClass('infoadd');
            $('.next').removeClass('slides_show');
            $('.prev').removeClass('slides_show');    
        });
        
        
    });
    function change(){
        var r=$(".current").find("a").attr('rel');
        if(r==0){$('.info').text('如果能让我重新在来一次，我希望不曾出现在你的生命里。这对我来说已经来不及了，因为我已经无法自拔');}
        if(r==1){$('.info').text('22222');}
        if(r==2){$('.info').text('33333');}
        if(r==3){$('.info').text('44444');}
        if(r==4){$('.info').text('55555');}
    }

完工！
