通过滑动门效果就可以实现;原理:载入的时候只显示1号层,隐藏2-N号层.当你点击按钮的时候,隐藏1号层,并显示相应的层;代码如下:<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>滑动门通用JS</title><style type="text/css"><!--body{margin:0px;padding:0px;font-size:12px;background:#eee;line-height:20px;}.bodyer{width:760px;margin:20px auto auto;border:1px dotted #ccc;background:#fff;} .t_rt{text-align:right;}h1,h2,h3,h4,h5,h6{font-weight:bold;margin:0px;padding:0px;font-size:12px;}ul,li{margin:0px;padding:0px;}li{list-style-type:none;}h1{margin:10px;padding-right:10px;padding-bottom:5px;border-bottom:1px dotted #ccc;}.preview{margin:10px;padding:10px;overflow:hidden;background:#eee;}.cont{padding:10px;}.cls{clear:both;}.hidden{display:none;}#sourse{border:1px dotted #ccc;width:600px;height:300px;margin:0px auto;}.textDiv{margin:10px 40px 10px;text-align:center;}h2{margin:0px 10px;background:#ccc;padding:5px;}.example{margin:10px;background:#FFF;border:1px dotted #ccc;padding:10px;}.scrolldoorFrame{width:400px;margin:0px auto;overflow:hidden;}.scrollUl{width:400px;border-bottom:1px solid #CCC;overflow:hidden;height:35px;}.scrollUl li{float:left;}.bor03{border:1px solid #ccc;border-top-width:0px;}.sd01{cursor:pointer;border:1px solid #CCC;background:#FFF;margin:5px;padding:2px;font-weight:bold;}.sd02{cursor:pointer;border:0px solid #CCC;margin:5px;padding:2px;}--></style><script type="text/javascript">function scrollDoor(){}scrollDoor.prototype = { sd : function(menus,divs,openClass,closeClass){ var _this = this; if(menus.length != divs.length) { alert("菜单层数量和内容层数量不一样!"); return false; } for(var i = 0 ; i < menus.length ; i++) { _this.$(menus[i]).value = i; _this.$(menus[i]).onmouseover = function(){ for(var j = 0 ; j < menus.length ; j++) { _this.$(menus[j]).className = closeClass; _this.$(divs[j]).style.display = "none"; } _this.$(menus[this.value]).className = openClass; _this.$(divs[this.value]).style.display = "block"; } } }, $ : function(oid){ if(typeof(oid) == "string") return document.getElementById(oid); return oid; }}window.onload = function(){ var SDmodel = new scrollDoor(); SDmodel.sd(["m01","m02","m03","m04","m05"],["c01","c02","c03","c04","c05"],"sd01","sd02"); SDmodel.sd(["mm01","mm02","mm03","mm04","mm05"],["cc01","cc02","cc03","cc04","cc05"],"sd01","sd02"); SDmodel.sd(["mmm01","mmm02","mmm03","mmm04","mmm05"],["ccc01","ccc02","ccc03","ccc04","ccc05"],"sd01","sd02");}</script></head><body><div class="bodyer"> <h1 class="t_rt"> 滑动门封装类 </h1> <h2> 效果预览 </h2> <div class="preview"> <div class="scrolldoorFrame"> <ul class="scrollUl"> <li class="sd01" id="m01">滑动门</li> <li class="sd02" id="m02">滑动门</li> <li class="sd02" id="m03">滑动门</li> <li class="sd02" id="m04">滑动门</li> <li class="sd02" id="m05">滑动门</li> </ul> <div class="bor03 cont"> <div id="c01"> 第一层内容 </div> <div id="c02" class="hidden"> 第二层内容 </div> <div id="c03" class="hidden"> 第三层内容 </div> <div id="c04" class="hidden"> 第四层内容 </div> <div id="c05" class="hidden"> 第五层内容 </div> </div> </div> </div> <div class="preview"> <div class="scrolldoorFrame"> <ul class="scrollUl"> <li class="sd01" id="mm01">滑动门</li> <li class="sd02" id="mm02">滑动门</li> <li class="sd02" id="mm03">滑动门</li> <li class="sd02" id="mm04">滑动门</li> <li class="sd02" id="mm05">滑动门</li> </ul> <div class="bor03 cont"> <div id="cc01"> 第一层内容 </div> <div id="cc02" class="hidden"> 第二层内容 </div> <div id="cc03" class="hidden"> 第三层内容 </div> <div id="cc04" class="hidden"> 第四层内容 </div> <div id="cc05" class="hidden"> 第五层内容 </div> </div> </div> </div> <div class="preview"> <div class="scrolldoorFrame"> <ul class="scrollUl"> <li class="sd01" id="mmm01">滑动门</li> <li class="sd02" id="mmm02">滑动门</li> <li class="sd02" id="mmm03">滑动门</li> <li class="sd02" id="mmm04">滑动门</li> <li class="sd02" id="mmm05">滑动门</li> </ul> <div class="bor03 cont"> <div id="ccc01"> 第一层内容 </div> <div id="ccc02" class="hidden"> 第二层内容 </div> <div id="ccc03" class="hidden"> 第三层内容 </div> <div id="ccc04" class="hidden"> 第四层内容 </div> <div id="ccc05" class="hidden"> 第五层内容 </div> </div> </div> </div></div></body></html>自己修改css来实现不同的效果按钮可以是图片,或者任意块级元素,也可以是链接;关键是id名称必须与JS里SDmodel.sd数组内一致.
