<!DOCTYPE html> <html> <head> <title>Layer group example</title> <script src="js/jquery-1.11.1.min.js"></script> <link rel="stylesheet" href="css/bootstrap.min.css"> <script src="js/bootstrap.min.js"></script> <style> #layertree li > span { cursor: pointer; } </style> <style> ul,ol { list-style: none } </style> </head> <body> <div id="layertree" class="span6"> <span>图层列表</span> <ul class='layer-list'> <li><input type="checkbox"><span>Food insecurity layer</span> <fieldset> <input class="opacity" type="range" min="0" max="1" step="0.01"/> </fieldset> </li> <li><input type="checkbox"><span>World borders layer</span> <fieldset> <input class="opacity" type="range" min="0" max="1" step="0.01"/> </fieldset> </li> </ul> </div> <script> $('#layertree li > span').click(function() { $(this).siblings('fieldset').toggle(); }).siblings('fieldset').hide(); </script> </body> </html>
其中：
1. <html>标签<ul>表示无序列表；<ol>比奥斯有序列表
2. 以下格式，表示每一小项的前边没有默认的黑点
ul,ol {
list-style: none
}
