jq图片切换特效
首先引入js，内容如下：
1 (function($){$.fn.slides=function(option){option=$.extend({},$.fn.slides.option,option);return this.each(function(){$(‘.‘+option.container,$(this)).children().wrapAll(‘<div

if(start<0){start=0;};if(start>total){start=total-1;};if(option.start){current=start;};if(option.randomize){control.randomize();} 3 $(‘.‘+option.container,elem).css({overflow:‘hidden‘,position:‘relative‘});control.css({position:‘relative‘,width:(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);}

5 if(option.bigTarget){control.children().css({cursor:‘pointer‘});control.children().click(function(){animate(‘next‘,effect);return false;});} 6

$(‘.‘+option.paginationClass+‘ li a:eq(‘+start+‘)‘,elem).parent().addClass(‘current‘);$(‘.‘+option.paginationClass+‘ li

li.current a‘,elem).attr(‘rel‘);if(next>prev){position=width*2;direction=-width*2;}else{position=0;direction=0;}11 current=next;break;}12 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‘);}});}13

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

$clone=$child.clone(true);$clone.show().appendTo($this);if(callback!==undefined){callback($child,$clone);}17 $child.remove();});}}));};})(jQuery);
其次html代码：
1 <div id="container-img"> 2 <div id="example"> 3 4 <div id="slides"> 5 <div class="info" title=""></div> 6 <div class="slides_container"> 7 <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-1.jpg" width="570" height="270" alt="1"></a> 8 <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-2.jpg" width="570" height="270" alt="2"></a> 9 <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-3.jpg" width="570" height="270" alt="3"></a>10 <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-4.jpg" width="570" height="270" alt="4"></a>11 <a href="" title="" ><img src="__ROOT__/Public/showimages/img/slide-5.jpg" width="570" height="270" alt="5"></a>12 </div>13 <a href="#" class="prev"><img src="__ROOT__/Public/showimages/img/arrow-prev.png" width="24" height="43" alt="Arrow Prev"></a>14 <a href="#" class="next"><img src="__ROOT__/Public/showimages/img/arrow-next.png" width="24" height="43" alt="Arrow Next"></a>15 </div>16
然后上css：
1 /* 2 Resets defualt browser settings 3 reset.css 4 */ 5 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; } 6 :focus { outline:0; } 7 a:active { outline:none; } 8 body {font-family: ‘微软雅黑‘; font-size: 14px;} 9 ol,ul { list-style:none; } 10 table { border-collapse:separate; border-spacing:0; } 11 caption,th,td { text-align:left; font-weight:normal; } 12 blockquote:before,blockquote:after,q:before,q:after { content:""; } 13 blockquote,q { quotes:"" ""; } 14 15 16 #container { 17 width:400px; 18 padding:0px; 19 margin:0 auto; 20 position:relative; 21 z-index:0; 22 } 23 24 #example { 25 width:400px; 26 height:270px; 27 position:relative; 28 } 29 30 #ribbon { 31 position:absolute; 32 top:-3px; 33 left:-3px; 34 z-index:500; 35 } 36 37 #frame { 38 position:absolute; 39 z-index:0; 40 width:450px; 41 height:341px; 42 top:-3px; 43 left:00px; 44 } 45 46 #slides { 47 position:absolute; 48 top:0px; 49 left:0px; 50 z-index:100; 51 } 52 53 #slides .next,#slides .prev { 54 position:absolute; 55 top:107px; 56 left:0px; 57 width:24px; 58 height:43px; 59 display: none; 60 61 62 63 } 64 #slides .next:hover,#slides .prev:hover{ 65 display: block!important; 66 z-index:101; 67 } 68 .slides_show{ 69 display: block!important; 70 z-index:101; 71 } 72 73 .slides_container { 74 width:400px; 75 height:270px; 76 overflow:hidden; 77 position:relative; 78 box-shadow: 0 0 10px #888; 79 } 80 .slides_container a:hover{opacity: 1;} 81 .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;} 82 .info:hover{margin-top: 230px;color: #fff;} 83 .infoadd{background: rgba(0, 0, 0, 0.2) !important; /* IE无效，FF有效 */ 84 85 background: #fff;color: #fff;text-shadow:0 0 1px #888; 86 87 filter: alpha(opacity=60);margin-top: 230px;display:inline;} 88 #slides .next { 89 left:375px; 90 91 } 92 93 .pagination { 94 margin:0px auto 0; 95 width:100px; 96 97 } 98 99 .pagination li {100 float:left;101 margin:0 1px;102 }103 104 .pagination li a {105 display:block;106 width:12px;107 height:0;108 padding-top:12px;109 background-image:url(../img/pagination.png);110 background-position:0 0;111 float:left;112 overflow:hidden;113 }114 115 .pagination li.current a {116 background-position:0 -12px;117 }118 119 a:link,a:visited {120 color:#599100;121 text-decoration:none;122 }123 124 a:hover,a:active {125 color:#599100;126 }
最后加上jq鼠标经过图像显示文字效果：
1 $(function(){ 2 $(‘#slides‘).slides({ 3 preload: true, 4 preloadImage: ‘img/loading.gif‘, 5 play: 5000, 6 pause: 2500, 7 hoverPause: true 8 }); 9 10 setInterval(‘change()‘,100);11 $(".slides_container").find(‘img‘).live(‘mouseover‘,function(){12 b=$(this).attr(‘alt‘);13 $(‘.info‘).addClass(‘infoadd‘); 14 $(‘.next‘).addClass(‘slides_show‘);15 $(‘.prev‘).addClass(‘slides_show‘); 16 //alert(r);17 $(this).attr(‘title‘,text);18 19 })20 $(".slides_container").find(‘img‘).live(‘mouseout‘,function(){21 $(".info").removeClass(‘infoadd‘);22 $(‘.next‘).removeClass(‘slides_show‘);23 $(‘.prev‘).removeClass(‘slides_show‘); 24 });25 26 27 });28 function change(){29 var r=$(".current").find("a").attr(‘rel‘);30 if(r==0){$(‘.info‘).text(‘如果能让我重新在来一次，我希望不曾出现在你的生命里。这对我来说已经来不及了，因为我已经无法自拔‘);}31 if(r==1){$(‘.info‘).text(‘22222‘);}32 if(r==2){$(‘.info‘).text(‘33333‘);}33 if(r==3){$(‘.info‘).text(‘44444‘);}34 if(r==4){$(‘.info‘).text(‘55555‘);}35 }
完工！
