二次开发-开发方法-给操作菜单增加子菜单
本帖最后由 adminlily 于 2020-12-14 17:08 编辑在iTop中添加新的弹出菜单项从iTop 2.0.0开始，该框架支持在iTop中存在的所有弹出菜单中添加新菜单项：在列表中（“ Other操作活动…”和“工具包”菜单中），列表中的“ Other操作活动…”中。操作活动的详细信息，“注销”菜单中的等等。
通过提供实现iPopupMenuExtension接口的PHP类，添加了新的弹出菜单项。
要在iTop页面左侧的主菜单中插入新条目，请参阅XML引用 关于菜单。
此示例演示以下内容：
[*]在iTop中的任何对象列表上，此扩展都添加一个新菜单项（在“其他操作活动…”弹出菜单中），该菜单项仅调用自定义javascript职能并使用列表中的元素数执行“告警（…）”

[*]在iTop中任何对象的“详细信息”页面上，扩展程序都会添加一个额外的菜单项“ Google this…”，以打开Google搜索页面（在新的选项卡窗口中），并在搜索文本中填充选定的itop对象的名称。

[*]在联系人（即团队或人员）的“详细信息”页面上，添加了两个额外的菜单项：
[*]分隔线（仅适用于iTop 2.0.1-beta或更高版本）
[*]调用自定义JS职能…的菜单项，只是弹出带有对象名称的告警（…）

PHP代码有趣的部分位于文件main.sample-add-menu.php中。自定义JS函数位于文件jsssample.js中。
随时修改此样本以将其调整为需求…，并从中做出一些有用的事情。
实现iPopupMenuExtension接口
为了将新的弹出菜单项添加到iTop中，必须提供实现iPopupMenuExtension接口的类。这个新类必须包含在iTop文件的包含链中的某个位置。文件的位置并不重要。确保文件正确包含在iTop中的最简单方法是将其添加到iTop模块定义文件中声明的“数据模型”文件列表中。
在我们的示例中，我们将代码放入名为main.sample-add-menu.php的PHP文件中。通过将其名称添加到module.sample-add-menu.php的数据模型文件列表中，确保包含此文件：
[ ttps://www.itophub.io/wiki/page?do=export_code&id=2_5_0%3Acustomization%3Aadd-menu-sample&codeblock=0]module-sample-add-menu.php
<?php
//
// iTop module definition file
//
SetupWebPage::AddModule(
__FILE__, // Path to the current file, all other file names are relative to
the directory containing this file
'sample-add-menu/',
(
// Identification
//
'label' => 'Add Menu Sample',
'category' => 'business',
// Setup
//
'dependencies' => (
),
'mandatory' => false,
'visible' => true,
// Components
//
'datamodel' => (
'main.sample-add-menu.php',
'model.sample-add-menu.php'
),
'webservice' => (
),
'data.struct' => (
// add your 'structure' definition XML files here,
),
'data.sample' => (
// add your sample data XML files here,
),
// Documentation
//
'doc.manual_setup' => '', // hyperlink to manual setup
documentation, if any
'doc.more_information' => '', // hyperlink to more information, if
any
// Default settings
//
'settings' => (
// Module specific settings go here, if any
),
)
);
然后，让我们创建实现iPopupMenuExtension接口的类：
[ ttps://www.itophub.io/wiki/page?do=export_code&id=2_5_0%3Acustomization%3Aadd-menu-sample&codeblock=1]main.sample-add-menu.php
<?php/** * Sample extension to show how adding menu items in iTop * This extension does nothing really useful but shows how to use the three
possible * types of menu items: * * - An URL to any web page * - A Javascript function call * - A separator (horizontal line in the menu) */class AddMenuSampleExtension implements iPopupMenuExtension{ /** * Get the list of items to be added to a menu. * * This method is called by the framework for each menu. * The items will be inserted in the menu in the order of the returned
array. * @param int $iMenuId The identifier of the type of menu, as listed by the
constants MENU_xxx * @param mixed $param Depends on $iMenuId, see the constants defined above * @return object[] An array of ApplicationPopupMenuItem or an empty array
if no action is to be added to the menu */ public static function EnumItems($iMenuId, $param) { $aResult = (); switch($iMenuId) // type of menu in which to add menu items { /** * Insert an item into the Actions menu of a list * * $param is a DBObjectSet containing the list of objects
*/ case iPopupMenuExtension::MENU_OBJLIST_ACTIONS: // Add a new menu item that triggers a custom JS function
defined in our own javascript file: js/sample.js $sModuleDir = ((__FILE__)); $sJSFileUrl = utils::GetAbsoluteUrlModulesRoot
().$sModuleDir.'/js/sample.js'; $iCount = $param->(); // number of objects in the set $aResult[] = new JSPopupMenuItem('_Custom_JS_', 'Custom JS
Function On List...', "MyCustomJSListFunction($iCount)", ($sJSFileUrl)); break; /** * Insert an item into the Toolkit menu of a list * * $param is a DBObjectSet containing the list of objects */ case iPopupMenuExtension::MENU_OBJLIST_TOOLKIT: break; /** * Insert an item into the Actions menu on an object's
details page * * $param is a DBObject instance: the object currently
displayed */ case iPopupMenuExtension::MENU_OBJDETAILS_ACTIONS: // For any object, add a menu "Google this..." that opens
google search in another window // with the name of the object as the text to search $aResult[] = new URLPopupMenuItem('_Google_this_', 'Google
this...', "h ?q=".$param->GetName(), '_blank'); // Only for Contact: (i.e. Teams and Persons) if ($param instanceof Contact) { // add a separator $aResult[] = new SeparatorPopupMenuItem(); // Note:
separator does not work in iTop 2.0 due to Trac #698, fixed in 2.0.1 // Add a new menu item that triggers a custom JS
function defined in our own javascript file: js/sample.js $sModuleDir = ((__FILE__)); $sJSFileUrl = utils::GetAbsoluteUrlModulesRoot
().$sModuleDir.'/js/sample.js'; $aResult[] = new JSPopupMenuItem('_Custom_JS_',
'Custom JS Function...', "MyCustomJSFunction('".($param->GetName())."')",
($sJSFileUrl)); } break; /** * Insert an item into the Dashboard menu * * The dashboad menu is shown on the top right corner of
the page when * a dashboard is being displayed. * * $param is a Dashboard instance: the dashboard currently
displayed */ case iPopupMenuExtension::MENU_DASHBOARD_ACTIONS: break; /** * Insert an item into the User menu (upper right corner of
the page) * * $param is null */ case iPopupMenuExtension::MENU_USER_ACTIONS: break; } return $aResult; }}
The two custom Javascript functions referenced in the code above are implemented in
the file js/sample.js:
sample.js
// Sample JS function to be called from a custom menu itemfunction MyCustomJSFunction(sName){ // nothing fancy here, just popup an alert alert(sName);} // Sample JS function to be called from a custom menu item// on a list of objectsfunction MyCustomJSListFunction(iCount){ alert('There are '+iCount+' element(s) in this list.');}

安装扩展
与其他任何iTop扩展一样：
[*]将zip文件的内容扩展到iTop根目录下的扩展文件夹中（如果需要，请创建扩展文件夹）
[*]确保Web服务器具有足够的权利来读取扩展文件夹中的所有文件
[*]删除配置文件上的只读标志（位于conf/production/config-itop.php中）
[*]将浏览器指向http ::: <itop-root >>安装程序，再次启动iTop安装程序。
[*]在安装向导的最后一步中，从扩展的列表中选择“添加菜单示例”。
