jquery+bootstrap自定义插件开发之dropdownlist

真的是不太会起名字了，这样吧，先把效果图上来大家看看吧。这个插件可以使用在 类似教师讲课或者章节之类吧

 这个效果用到了bootstrap这个轻量级的前端框架，真的是非常棒。引入bootstrap的资源文件后引入jqery是必须的。然后前端的DOM结构是这样的

< div  class ="btn-toolbar btn-toolbar-top"  id ="dropdown-list" >
                                         < div  class ="btn-group" >
                                             < a  class ="btn" >< i  class ="icon-list-alt" ></ i ></ a >
                                             < a  class ="btn dropdown-toggle"  data-toggle ="dropdown" >< span  class ="caret" ></ span ></ a >
                                             < ul  class ="dropdown-menu span3 dropdown-menu-scroll" >
                                                 < li >
                                                     < a  href ="#" >< span >1. </ span >
                                                         < p >安装Oracle </ p >
                                                     </ a >
                                                 </ li >
                                                 < li >
                                                     < a  href ="#" >< span >2. </ span >
                                                         < p >配置Oracle </ p >
                                                     </ a >
                                                 </ li >
                                                 < li >
                                                     < a  href ="#" >< span >3. </ span >
                                                         < p >Oracle配置向导 </ p >
                                                     </ a >
                                                 </ li >
                                                 < li >
                                                     < a  href ="#" >< span >4. </ span >
                                                         < p >第四步的内容 </ p >
                                                     </ a >
                                                 </ li >
                                             </ ul >
                                         </ div >
                                         < div  class ="btn-group btn-group-left" >
                                             < a  class ="btn"  id ="moveUp" >< i  class ="icon-chevron-left" ></ i ></ a >
                                             < a  class ="btn"  id ="moveDown" >< i  class ="icon-chevron-right" ></ i ></ a >
                                         </ div >
                                         < div  class ="btn-group btn-group-middle" >
                                            第 < span ></ span >个练习，共  < span ></ span >个练习
                                         </ div >

                                    </div>

调用就比较简单了

$("#dropdown-list").dropdownList( function(index){
                    $("#contents").attr("src",index+".html");//这个的作用是给下面的一个iframe更换src的

                }); 

给这个插件js文件起名dropdownlist.js  稍后会把整个源码打包。

大家看的效果图的下面的步骤一 步骤二 也是一个插件  这个插件会在下一篇文章中介绍 并提供下载敬请期待
