本文实例讲述了JS+CSS实现拖动分页效果的方法。分享给大家供大家参考。具体实现方法如下：
<html> <head> <title>拖动分页</title> <meta http-equiv=Content-Type content="text/html; charset=utf-8"> <style> body{ border:0px; margin:0px; overflow:hidden; background-color:transparent; } .page{ position:absolute; width:700px; border:1px solid #999; background-color:#000; left:425px; margin-left:-350px; cursor:default; z-index:0; } ul{ height:320px; list-style:none; margin:40px 50px 0px; padding:0px; } li{ width:100%; height:30px; line-height:30px; font-size:14px; text-align:left; border-bottom:1px dashed #999; } a{ text-decoration:none; color:#999; } a:hover{ font-weight:bold; } li span{ float:right; color:#999; } .tip{ display:block; width:100%; font-size:12px; color:#999; text-align:center; margin:10px 0px 20px; } </style> </head> <body onselectstart="return false;"> <script> function id(obj){ return document.getElementById(obj); } var page; var lm,mx; var md=false; var sh=0; var en=false; window.onload=function(){ page=document.getElementsByTagName("div"); if(page.length>0){ page[0].style.zIndex=2; } for(i=0;i<page.length;i++){ page[i].className="page"; page[i].innerHTML+="<span>第 "+(i+1)+"/"+page.length+" 页 提示：左右拖拽翻页</span>"; page[i].id="page"+i; page[i].i=i; page[i].onmousedown=function(e){ if(!en){ if(!e){e=e||window.event;} lm=this.offsetLeft; mx=(e.pageX)?e.pageX:e.x; this.style.cursor="w-resize"; md=true; if(document.all){ this.setCapture(); }else{ window.captureEvents(Event.MOUSEMOVE|Event.MOUSEUP); } } } page[i].onmousemove=function(e){ if(md){ en=true; if(!e){e=e||window.event;} var ex=(e.pageX)?e.pageX:e.x; this.style.left=ex-(mx-lm)+350; if(this.offsetLeft<75){ var cu=(this.i==0)?page.length-1:this.i-1; page[sh].style.zIndex=0; page[cu].style.zIndex=1; this.style.zIndex=2; sh=cu; } if(this.offsetLeft>75){ var cu=(this.i==page.length-1)?0:this.i+1; page[sh].style.zIndex=0; page[cu].style.zIndex=1; this.style.zIndex=2; sh=cu; } } } page[i].onmouseup=function(){ this.style.cursor="default"; md=false; if(document.all){ this.releaseCapture(); }else{ window.releaseEvents(Event.MOUSEMOVE|Event.MOUSEUP); } flyout(this); } } } function flyout(obj){ if(obj.offsetLeft<75){ if( (obj.offsetLeft + 350 - 20) > -275 ){ obj.style.left=obj.offsetLeft + 350 - 20; window.setTimeout("flyout(id('"+obj.id+"'));",0); }else{ obj.style.left=-275; obj.style.zIndex=0; flyin(id(obj.id)); } } if(obj.offsetLeft>75){ if( (obj.offsetLeft + 350 + 20) < 1125 ){ obj.style.left=obj.offsetLeft + 350 + 20; window.setTimeout("flyout(id('"+obj.id+"'));",0); }else{ obj.style.left=1125; obj.style.zIndex=0; flyin(id(obj.id)); } } } function flyin(obj){ if(obj.offsetLeft<75){ if( (obj.offsetLeft + 350 + 20) < 425 ){ obj.style.left=obj.offsetLeft + 350 + 20; window.setTimeout("flyin(id('"+obj.id+"'));",0); }else{ obj.style.left=425; en=false; } } if(obj.offsetLeft>75){ if( (obj.offsetLeft + 350 - 20) > 425 ){ obj.style.left=obj.offsetLeft + 350 - 20; window.setTimeout("flyin(id('"+obj.id+"'));",0); }else{ obj.style.left=425; en=false; } } } </script> <div> <ul> <li><span>2009-4-29 02:16</span><a href=#>东方之珠</a></li> <li><span>2009-4-29 02:16</span><a href=#>啊！爱人</a></li> <li><span>2009-4-29 02:16</span><a href=#>宁静温泉</a></li> <li><span>2009-4-29 02:16</span><a href=#>你的样子</a></li> <li><span>2009-4-29 02:16</span><a href=#>恋曲1980</a></li> <li><span>2009-4-29 02:16</span><a href=#>恋曲1980</a></li> <li><span>2009-4-29 02:16</span><a href=#>恋曲2000</a></li> <li><span>2009-4-29 02:16</span><a href=#>亚细亚的孤儿</a></li> <li><span>2009-4-29 02:16</span><a href=#>童年</a></li> </ul> </div> <div> <ul> <li><span>2009-4-29 02:16</span><a href=#>弹唱词</a></li> <li><span>2009-4-29 02:16</span><a href=#>飞车</a></li> <li><span>2009-4-29 02:16</span><a href=#>东方之珠</a></li> <li><span>2009-4-29 02:16</span><a href=#>滚滚红尘</a></li> <li><span>2009-4-29 02:16</span><a href=#>光阴的故事</a></li> <li><span>2009-4-29 02:16</span><a href=#>之乎者也</a></li> <li><span>2009-4-29 02:16</span><a href=#>现象七十二变</a></li> <li><span>2009-4-29 02:16</span><a href=#>乡愁四韵</a></li> <li><span>2009-4-29 02:16</span><a href=#>穿过你的黑发我的手</a></li> </ul> </div> <div> <ul> <li><span>2009-4-29 02:16</span><a href=#>大兵歌</a></li> <li><span>2009-4-29 02:16</span><a href=#>黄色面孔</a></li> <li><span>2009-4-29 02:16</span><a href=#>台北红玫瑰</a></li> </ul> </div> </body> </html>
