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
