　《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》

　　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：　　

一、“模块（菜单）”管理主界面UI的ASPX代码如下：

<%@ Page Language="C#" MasterPageFile="~/Site.Master"  AutoEventWireup="true" CodeBehind="ModuleAdmin.aspx.cs" Inherits="RDIFramework.WebApp.Modules.ModuleAdmin" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<div id="toolbar">

<%=base.BuildToolBarButtons()%>

</div>

<table id="navGrid"></table>

<script type="text/javascript" src="../Scripts/Linqjs/linq.min.js"></script>

<script type="text/javascript" src="../Scripts/Linqjs/linq.jquery.js"></script>

<script type="text/javascript" src="../Scripts/Business/ModuleAdmin.js?v=5"></script>

</asp:Content>

二：绑定当前登录用户所拥有的功能按钮列表代码如下：

private bool permissionUserModulePermission = false;

private bool permissionRoleModulePermission = false;

private bool permissionOrganizeModulePermission = false;

private bool permissionModuleConfig = false;

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

this.GetPermission();

}

/// <summary>

/// 获得页面的权限

/// </summary>

private void GetPermission()

{

this.permissionAdd = this.IsAuthorized("ModuleManagement.Add");

this.permissionEdit = this.IsAuthorized("ModuleManagement.Edit");

this.permissionDelete = this.IsAuthorized("ModuleManagement.Delete");

this.permissionExport = this.IsAuthorized("ModuleManagement.Export");

//this.permissionAccredit = this.IsAuthorized("UserManagement.Accredit");

this.permissionUserModulePermission = this.IsAuthorized("ModuleManagement.UserModulePermission");

this.permissionRoleModulePermission = this.IsAuthorized("ModuleManagement.RoleModulePermission");

this.permissionOrganizeModulePermission = this.IsAuthorized("ModuleManagement.OrganizeModulePermission") && SystemInfo.EnableOrganizePermission;

this.permissionModuleConfig = this.IsAuthorized("ModuleManagement.ModuleConfig");

}

/// <summary>

/// 加载工具栏

/// </summary>

/// <returns>工具栏HTML</returns>

public override string BuildToolBarButtons()

{

StringBuilder sb = new StringBuilder();

string linkbtn_template =

"<a id=\"a_{0}\" class=\"easyui-linkbutton\" style=\"float:left\"  plain=\"true\" href=\"javascript:;\" icon=\"{1}\"  {2} title=\"{3}\">{4}</a>"

;

sb.Append(

"<a id=\"a_refresh\" class=\"easyui-linkbutton\" style=\"float:left\"  plain=\"true\" href=\"javascript:;\" icon=\"icon-reload\"  title=\"重新加载\">刷新</a> "

);

sb.Append("<div class='datagrid-btn-separator'></div> ");

sb.Append(string.Format(linkbtn_template, "add", "icon-tab_add", permissionAdd ? "" : "disabled=\"True\"", "新增模块（菜单）", "新增"));

sb.Append(string.Format(linkbtn_template, "edit", "icon-tab_edit", permissionEdit ? "" : "disabled=\"True\"", "修改选中的模块（菜单）", "修改"));

sb.Append(string.Format(linkbtn_template, "delete", "icon-tab_delete", permissionDelete ? "" : "disabled=\"True\"", "删除选中的模块（菜单）", "删除"));

sb.Append("<div class='datagrid-btn-separator'></div> ");

//sb.Append(string.Format(linkbtn_template, "move", "icon-shape_move_forwards", permissionMove ? "" : "disabled=\"True\"", "移动选中的模块（菜单）", "移动"));

sb.Append(string.Format(linkbtn_template, "export", "icon-tab_go", permissionExport ? "" : "disabled=\"True\"", "导出模块（菜单）数据", "导出"));

sb.Append("<div class='datagrid-btn-separator'></div> ");

sb.Append(string.Format(linkbtn_template, "setusermodulepermission", "icon-user_key", permissionUserModulePermission ? "" : "disabled=\"True\"", "设置用户的模块（菜单）访问权限", "用户模块权限"));

sb.Append(string.Format(linkbtn_template, "setrolemodulepermission", "icon-group_key", permissionRoleModulePermission ? "" : "disabled=\"True\"", "设置角色的模块（菜单）访问权限", "角色模块权限"));

sb.Append("<div class='datagrid-btn-separator'></div> ");

sb.Append(string.Format(linkbtn_template, "moduleconfig", "icon-table_gear", permissionRoleModulePermission ? "" : "disabled=\"True\"", "设置模块的可用性", "模块配置"));

return sb.ToString();

}

三、绑定模块主wldmTreeGrid 的JS代码如下：

var grid = {

databind: function (winsize) {

navgrid = $('#navGrid').treegrid({

toolbar: '#toolbar',

title: '模块（菜单）列表',

iconCls: 'icon icon-chart_organisation',

width: winsize.width,

height: winsize.height,

nowrap: false,

rownumbers: true,

//animate: true,

resizable: true,

collapsible: false,

url: actionUrl,

idField: 'Id',

treeField: 'FullName',

frozenColumns: [[

{ title: '模块（菜单）名称', field: 'FullName', width: 200 },

{ title: '编码', field: 'Code', width: 130 }

]],

columns: [[

{ title: 'Id', field: 'Id', hidden: true },

{ title: 'ParentId', field: 'ParentId', hidden: true },

{ title: '模块分类', field: 'Category', width: 100 },

{ title: '图标', field: 'IconCss', width: 130, hidden: true },

{ title: 'Web链接地址', field: 'NavigateUrl', width: 200 },

{ title: 'WinForm程序集', field: 'AssemblyName', width: 150 },

{ title: 'WinForm窗体', field: 'FormName', width: 200 },

{

title: '公共', field: 'IsPublic', width: 50, align: 'center', formatter: function (v, d, i) {

return '<img src="http://images.cnblogs.com/' + (v ? "checkmark.gif" : "checknomark.gif") + '" />';

}

},

{ title: '有效', field: 'Enabled', width: 50, align: 'center', formatter: imgcheckbox },

{ title: 'AllowEdit', field: 'AllowEdit', hidden: true },

{ title: 'AllowDelete', field: 'AllowDelete', hidden: true },

{ title: '排序', field: 'SortCode', width: 80 },

{ title: '备注', field: 'Description', width: 500 }

]]

});

},

reload: function () {

navgrid.treegrid('reload');

},

selected: function () {

return navgrid.treegrid('getSelected');

}

};

var imgcheckbox = function (cellvalue, options, rowObject) {

return cellvalue ? '<img src="/css/icon/ok.png" alt="正常" title="正常" />' : '<img src="/css/icon/stop.png" alt="禁用" title="禁用" />';

}

四、添加与模块（菜单）主界面　　

　　代码如下：　

100

101

102

103

104

105

106

107

108

add: function () {

if ($(this).linkbutton('options').disabled == true) {

return;

}

var addDialog = top.$.hDialog({

href: formUrl, title: '添加模块（菜单）', iconCls: 'icon-tab_add', width: 490, height: 550,

onLoad: function () {

crud.bindCtrl();

crud.bindCategory();

var row = grid.selected();

if (row) {

top.$('#txt_ParentId').combotree('setValue', row.ParentId);

}

},

submit: function () {

if (top.$('#uiform').validate().form()) {

//var param = createParam('add', '0');

var vcategory = top.$('#txt_Category').combobox('getValue');

var vparentid = top.$('#txt_ParentId').combobox('getValue');

var param = 'action=Add&vcategory=' + vcategory + '&vparentid=' + vparentid + '&' + top.$('#uiform').serialize();

$.ajaxjson(actionUrl, param, function (d) {

if (d.Success) {

msg.ok(d.Message);

addDialog.dialog('close');

grid.reload();

} else {

MessageOrRedirect(d);

}

});

}

});

},

edit: function () {

if ($(this).linkbutton('options').disabled == true) {

return;

}

var row = grid.selected();

if (row) {

var editDailog = top.$.hDialog({

href: formUrl, title: '修改模块（菜单）', iconCls: 'icon-tab_edit', width: 490, height: 550,

onLoad: function () {

crud.bindCtrl(row.Id);

crud.bindCategory();

top.$('#txt_Code').val(row.Code);

top.$('#txt_FullName').val(row.FullName);

top.$('#txt_Category').combobox('setValue', row.Category);

top.$('#txt_ParentId').combotree('setValue', row.ParentId);

top.$('#txt_NavigateUrl').val(row.NavigateUrl);

top.$('#txt_IconCss').val(row.IconCss);

//top.$('#smallIcon').attr('class', "icon " + row.IconCss);

top.$('#smallIcon').attr('class', row.IconCss);

top.$('#txt_AssemblyName').val(row.AssemblyName);

top.$('#txt_FormName').val(row.FormName);

top.$('#chk_Enabled').attr('checked', row.Enabled == "1");

top.$('#chk_IsPublic').attr('checked', row.IsPublic == "1");

top.$('#chk_Expand').attr('checked', row.Expand == "1");

top.$('#chk_AllowEdit').attr('checked', row.AllowEdit == "1");

top.$('#chk_AllowDelete').attr('checked', row.AllowDelete == "1");

top.$('#txt_Description').val(row.Description);

top.$('#txt_IconUrl').val(row.IconUrl);

},

submit: function () {

if (top.$('#uiform').validate().form()) {

//保存时判断当前节点所选的父节点，不能为当前节点的子节点，这样就乱套了....

var treeParentId = top.$('#txt_ParentId').combotree('tree'); // 得到树对象

var node = treeParentId.tree('getSelected');

if (node) {

var nodeParentId = treeParentId.tree('find', row.Id);

var children = treeParentId.tree('getChildren', nodeParentId.target);

var nodeIds = '';

var isFind = 'false';

for (var index = 0; index < children.length; index++) {

if (children[index].id == node.id) {

isFind = 'true';

break;

}

if (isFind == 'true') {

top.$.messager.alert('温馨提示', '请选择父节点元素！', 'warning');

return;

}

var vcategory = top.$('#txt_Category').combobox('getValue');

var vparentid = top.$('#txt_ParentId').combobox('getValue');

var query = 'action=Edit&vcategory=' + vcategory + '&vparentid=' + vparentid + '&KeyId=' + row.Id + '&' + top.$('#uiform').serialize();

$.ajaxjson(actionUrl, query, function (d) {

if (d.Success) {

msg.ok(d.Message);

editDailog.dialog('close');

grid.reload();

} else {

MessageOrRedirect(d);

}

});

}

});

} else {

msg.warning('请选择要修改菜单!');

return false;

}

return false;

}

　　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：　

<ul id="iconlist" style="margin:0px;padding:0px; list-style-type:none;">

<li title="/css/icon/accept.png"><span class="icon icon-accept"> </span></li>

<li title="/css/icon/add.png"><span class="icon icon-add"> </span></li>

<li title="/css/icon/advancedsettings.png"><span class="icon icon-advancedsettings"> </span></li>

<li title="/css/icon/advancedsettings2.png"><span class="icon icon-advancedsettings2"> </span></li>

<li title="/css/icon/anchor.png"><span class="icon icon-anchor"> </span></li>

<li title="/css/icon/application.png"><span class="icon icon-application"> </span></li>

<li title="/css/icon/application_delete.png"><span class="icon icon-application_delete"> </span></li>

<li title="/css/icon/application_double.png"><span class="icon icon-application_double"> </span></li>

<li title="/css/icon/application_edit.png"><span class="icon icon-application_edit"> </span></li>

<li title="/css/icon/application_error.png"><span class="icon icon-application_error"> </span></li>

<li title="/css/icon/application_form.png"><span class="icon icon-application_form"> </span></li>

<li title="/css/icon/application_form_add.png"><span class="icon icon-application_form_add"> </span></li>

<li title="/css/icon/application_form_delete.png"><span class="icon icon-application_form_delete"> </span></li>

<li title="/css/icon/application_form_edit.png"><span class="icon icon-application_form_edit"> </span></li>

<li title="/css/icon/application_form_magnify.png"><span class="icon icon-application_form_magnify"> </span></li>

<li title="/css/icon/application_get.png"><span class="icon icon-application_get"> </span></li>

<li title="/css/icon/application_go.png"><span class="icon icon-application_go"> </span></li>

<li title="/css/icon/application_home.png"><span class="icon icon-application_home"> </span></li>

<li title="/css/icon/application_key.png"><span class="icon icon-application_key"> </span></li>

<li title="/css/icon/application_lightning.png"><span class="icon icon-application_lightning"> </span></li>

<ul><span style="font-family: verdana, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 1.5; "> </span>

　　然后在我们的js中调用这个html做相应的处理即可了，js部分代码为：

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。

　　js代码如下：

userModulePermissionBatchSet: function () { //用户模块（菜单）权限批量设置

if ($(this).linkbutton('options').disabled == true) {

return;

}

var userGrid;

var curUserModuleIds = []; //当前所选用户所拥有的模块ID

var setDialog = top.$.hDialog({

title: '用户模块（菜单）权限批量设置',

width: 670, height: 600, iconCls: 'icon-user_key', //cache: false,

href: "Modules/html/PermissionBacthSetForm.htm?n=" + Math.random(),

onLoad: function () {

using('panel', function () {

top.$('#panelTarget').panel({ title: '模块（菜单）', iconCls: 'icon-org', height: $(window).height() - 3 });

});

userGrid = top.$('#leftnav').datagrid({

title: '所有用户',

url: 'Modules/handler/UserAdminHandler.ashx',

nowrap: false, //折行

//fit: true,

rownumbers: true, //行号

striped: true, //隔行变色

idField: 'Id', //主键

singleSelect: true, //单选

frozenColumns: [[]],

columns: [[

{ title: '登录名', field: 'UserName', width: 120, align: 'left' },

{ title: '用户名', field: 'RealName', width: 150, align: 'left' }

]],

onLoadSuccess: function (data) {

top.$('#rightnav').tree({

cascadeCheck: false, //联动选中节点

checkbox: true,

lines: true,

url: 'Modules/handler/ModuleAdminHandler.ashx?action=GetModuleTree',

onSelect: function (node) {

top.$('#rightnav').tree('getChildren', node.target);

}

});

top.$('#leftnav').datagrid('selectRow', 0);

},

onSelect: function (rowIndex, rowData) {

curUserModuleIds = [];

var query = 'action=GetModuleByUserId&userid=' + rowData.Id;

$.ajaxtext('handler/PermissionHandler.ashx', query, function (data) {

var moduelTree = top.$('#rightnav');

moduelTree.tree('uncheckedAll');

if (data == '' || data.toString() == '[object XMLDocument]') {

return;

}

curUserModuleIds = data.split(',');

for (var i = 0; i < curUserModuleIds.length; i++) {

var node = moduelTree.tree('find', curUserModuleIds[i]);

if (node)

moduelTree.tree("check", node.target);

}

});

}

});

},

submit: function () {

var allSelectModuledIds = permissionMgr.getUserSelectedModule().split(',');

var grantModuleIds = '';

var revokeModuleIds = '';

var flagRevoke = 0;

var flagGrant = 0;

while (flagRevoke < curUserModuleIds.length) {

if ($.inArray(curUserModuleIds[flagRevoke], allSelectModuledIds) == -1) {

revokeModuleIds += curUserModuleIds[flagRevoke] + ','; //得到收回的权限列表

}

++flagRevoke;

}

while (flagGrant < allSelectModuledIds.length) {

if ($.inArray(allSelectModuledIds[flagGrant], curUserModuleIds) == -1) {

grantModuleIds += allSelectModuledIds[flagGrant] + ','; //得到授予的权限列表

}

++flagGrant;

}

var query = 'action=SetUserModulePermission&userid=' + top.$('#leftnav').datagrid('getSelected').Id + '&grantIds=' + grantModuleIds + "&revokeIds=" + revokeModuleIds;

$.ajaxjson('handler/PermissionHandler.ashx', query, function (d) {

if (d.Data > 0) {

msg.ok('设置成功！');

}

else {

alert(d.Message);

}

});

}

});

}

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。

　　js部分代码如下：

roleModulePermissionBatchSet: function () { //角色模块（菜单）权限批量设置

if ($(this).linkbutton('options').disabled == true) {

return;

}

var roleGrid;

var curRoleModuleIds = []; //当前所选角色所拥有的模块ID

var setDialog = top.$.hDialog({

title: '角色模块（菜单）权限批量设置',

width: 670, height: 600, iconCls: 'icon-group_key', //cache: false,

href: "Modules/html/PermissionBacthSetForm.htm?n=" + Math.random(),

onLoad: function () {

using('panel', function () {

top.$('#panelTarget').panel({ title: '模块（菜单）', iconCls: 'icon-org', height: $(window).height() - 3 });

});

roleGrid = top.$('#leftnav').datagrid({

title: '所有角色',

url: 'Modules/handler/RoleAdminHandler.ashx?action=getrolelist',

nowrap: false, //折行

//fit: true,

rownumbers: true, //行号

striped: true, //隔行变色

idField: 'Id', //主键

singleSelect: true, //单选

frozenColumns: [[]],

columns: [[

{ title: '角色编码', field: 'Code', width: 120, align: 'left' },

{ title: '角色名称', field: 'RealName', width: 150, align: 'left' }

]],

onLoadSuccess: function (data) {

top.$('#rightnav').tree({

cascadeCheck: false, //联动选中节点

checkbox: true,

lines: true,

url: 'Modules/handler/ModuleAdminHandler.ashx?action=GetModuleTree',

onSelect: function (node) {

top.$('#rightnav').tree('getChildren', node.target);

}

});

top.$('#leftnav').datagrid('selectRow', 0);

},

onSelect: function (rowIndex, rowData) {

curRoleModuleIds = [];

var query = 'action=GetModuleByRoleId&roleid=' + rowData.Id;

$.ajaxtext('handler/PermissionHandler.ashx', query, function (data) {

var moduelTree = top.$('#rightnav');

moduelTree.tree('uncheckedAll');

if (data == '' || data.toString() == '[object XMLDocument]') {

return;

}

curRoleModuleIds = data.split(',');

for (var i = 0; i < curRoleModuleIds.length; i++) {

var node = moduelTree.tree('find', curRoleModuleIds[i]);

if (node)

moduelTree.tree("check", node.target);

}

});

}

});

},

submit: function () {

var allSelectModuledIds = permissionMgr.getUserSelectedModule().split(',');

var grantModuleIds = '';

var revokeModuleIds = '';

var flagRevoke = 0;

var flagGrant = 0;

while (flagRevoke < curRoleModuleIds.length) {

if ($.inArray(curRoleModuleIds[flagRevoke], allSelectModuledIds) == -1) {

revokeModuleIds += curRoleModuleIds[flagRevoke] + ','; //得到收回的权限列表

}

++flagRevoke;

}

while (flagGrant < allSelectModuledIds.length) {

if ($.inArray(allSelectModuledIds[flagGrant], curRoleModuleIds) == -1) {

grantModuleIds += allSelectModuledIds[flagGrant] + ','; //得到授予的权限列表

}

++flagGrant;

}

var query = 'action=SetRoleModulePermission&roleid=' + top.$('#leftnav').datagrid('getSelected').Id + '&grantIds=' + grantModuleIds + "&revokeIds=" + revokeModuleIds;

$.ajaxjson('handler/PermissionHandler.ashx', query, function (d) {

if (d.Data > 0) {

msg.ok('设置成功！');

}

else {

alert(d.Message);

}

});

}

});

}
