我们分享了使用Jquery EasyUI来进行ASP.NET项目的开发的相关方法，每一个模块都有其共用性，细细理解与掌握，我相信使用EasyUI进行开发还是相当方便的，每篇文章，我们力求通俗易懂。
接下来我分享“模块（菜单）”模块主要的核心代码，“模块（菜单）”管理模块同样使用了EasyUI的TreeGrid控件，对于EasyUI的TreeGrid控件的具体使用方法可以参见上一篇 《使用Jquery+EasyUI 进行框架项目开发案例讲解之三---组织机构源码分享》的说明，或看相关的Easy UI的帮助文件，同时，我们可以看一下如何做模块图标的选择界面，模块（菜单）主界面如下图所示：

在模块（菜单）编辑与新增界面上，我们可以设置模块的图标，设置模块图标如下图所示：
这个是如何实现的呢？
首先准备图标的基页面，截取部分格式如下，保存为一个html文件，如:iconlist.htm：

var showIcon = function () {
top.$('#selecticon').click(function () {
var iconDialog = top.$.hDialog({
iconCls: 'icon-application_view_icons',
href: '/css/iconlist.htm?v=' + Math.random(),
title: '选取图标', width: 800, height: 600, showBtns: false,
onLoad: function () {
top.$('#iconlist li').attr('style', 'float:left;border:1px solid #fff;margin:2px;width:16px;cursor:pointer').click(function () {
//var iconCls = top.$(this).find('span').attr('class').replace('icon ', '');
var iconCls = top.$(this).find('span').attr('class');
top.$('#txt_IconCss').val(iconCls);
top.$('#txt_IconUrl').val(top.$(this).attr('title'));
//top.$('#smallIcon').attr('class', "icon " + iconCls);
top.$('#smallIcon').attr('class', iconCls);
iconDialog.dialog('close');
}).hover(function () {
top.$(this).css({ 'border': '1px solid red' });
}, function () {
top.$(this).css({ 'border': '1px solid #fff' });
});
}
});
});
}; |
五、用户模块（菜单）权限批量设置
用户模块（菜单）权限功能项用于设置那些用户可以访问那些模块，那些用户不能访问那些模块。用户模块（菜单）权限设置如下图用户模块（菜单）权限集中设置。左侧列出框架的所有有效用户，右侧为模块（菜单）项，选中相应的模块后保存，即可为当前选中用户授予模块的访问权限。

六、角色模块（菜单）权限批量设置
角色模块（菜单）操作权限用于设置那些角色拥有那些操作（功能）权限，那些角色不拥有那些操作（功能）权限。如下图所示，左侧列出框架的所有有效角色，右侧为相应的模块（菜单），选中相应的模块（菜单）后保存，即可为当前选中角色授予相应的模块（菜单）可访问的控制。
