使用Jquery+EasyUI 进行框架项目开发案例讲解之三
角色管理源码分享
在上两篇文章
《使用Jquery+EasyUI进行框架项目开发案例讲解之一---员工管理源码分享》
《使用Jquery+EasyUI 进行框架项目开发案例讲解之二---用户管理源码分享》
我们分享了使用Jquery EasyUI来进行UI布局等开发的相关方法,也许你在使用EasyUI的过程过更熟练,有更方便快捷的技巧,我强烈建议你可以分享出来,大家共同进步、共同学习,谢谢!
接下来我分享“角色管理”模块主要的核心代码,角色管理主界面如下图所示:
首先是角色管理的UI界面aspx代码如下:

角色添加界面如下:
角色修改界面:
角色用户设置界面:
在上图中,我们可以添加、移除、清空当前角色包含的用户。
选择添加,打开“选取用户”窗口,如下图所示:
角色用户设置及用户选择界面JS代码如下:
var formHtml = '<div style="border-bottom:1px solid #CCC; margin-bottom:5px;"><span id="role_name" class="icon32 icon-group32" style="padding-left:48px;font-weight:bold; font-size:14px;color:#666;">角色名称</span> </div>';

// return; // } top.$.messager.confirm('询问提示', '确认要清除所有用户吗?', function (data) { if (data) { top.$('#user_groups').empty(); } }); return false; }); }); }
特别说明一下,在选取用户界面,使用的是checkbox控件,得到选中的checkbox,是使用下面的实例代码:
<input id="checkbox1" type="checkbox" checked> <input id="checkbox2" type="checkbox>
$("#checkbox1").is(":checked") // true $("#checkbox2").is(":checked") // false //注意不是使用下面的方法 $("#checkbox1").attr("checked") // checked $("#checkbox2").attr("checked") // undefined
