在網頁中使用自定義右鍵菜單,實現上皆為使用javascript禁用瀏覽器默認的右鍵菜單,然后在網頁中響應鼠標右鍵事件,彈出自定義的菜單。
類似右鍵菜單的組件網上很多。一般而言,改變瀏覽器的默認菜單應當慎用,這會使多數用戶感到不習慣。但是在企業Web應用中,用戶的使用環境更加可控,在這種應用中使用自定義右鍵菜單會更加適合。
以下列舉幾款比較成熟的jQuery右鍵菜單插件,我們將逐一介紹,請讀者自行比較,並根據自己的需求選擇。
1.VERY SIMPLE CONTEXT MENU-Intekhab A Rizvi
Project Page: http://intekhabrizvi.wordpress.com/2010/01/28/jquery-very-simple-contextmenu-plugin/
jQuery Very Simple ContextMenu Plugin
使用:
1.在插件主頁下載所需文件。
2.在你的html文件中包含jquery庫,vscontext.jquery.js,css/vscontext.css。
<script src="jquery.js" type="text/javascript"><!--mce:0--></script>
<script src="vscontext.jquery.js" type="text/javascript"><!--mce:1--></script>
3.在html中創建要響應右鍵菜單的元素。
<div id="item">右鍵點我</div>
4.創建菜單項目。
<li>的class有seprator的,會在該項下面有一條分割線。
<div >
<ul>
<li ><a id="menu_1" href="javascript:cut();">剪切</a></li>
<li ><a id="menu_2" href="javascript:copy();">復制</a></li>
<li ><a id="menu_3" href="javascript:paste();">粘貼</a></li>
<li ><a id="menu_4" href="javascript:edit();">編輯</a></li>
<li ><a id="menu_5" href="javascript:del();">刪除</a></li>
</ul>
</div>
菜單項的圖標要在css文件里設置相應<li>的背景。
.vs-context-menu li.cut a { background-image: url(icons/cut.png); }
.vs-context-menu li.copy a { background-image: url(icons/copy.png); }
.vs-context-menu li.paste a { background-image: url(icons/paste.png); }
.vs-context-menu li.edit a { background-image: url(icons/edit.png); }
.vs-context-menu li.delete a { background-image: url(icons/delete.png); }
5.初始化菜單,添加菜單事件。
<script type="text/javascript"><!--mce:2--></script>
2.CONTEXT MENU-Cory S.N. LaViska
Project Page: http://abeautifulsite.net/blog/2008/09/jquery-context-menu-plugin/
jQuery Context Menu Plugin
使用:見插件官方網站。
Methods:
| disableContextMenu() | 禁用匹配元素上的右鍵菜單。 |
| enableContextMenu() | 啟用匹配元素上的右鍵菜單。 |
| disableContextMenuItems(”#option1,#option2,…”) | 禁用匹配的菜單項,如果參數為null,禁用所有項。 |
| enableContextMenuItems(”#option1,#option2,…”) | 期用匹配的菜單項,如果參數為null,禁用所有項。 |
| destroyContextMenu() | 解除元素與右鍵菜單的綁定。 |
Callback:
| action | 選中的菜單項所對應的動作。 |
| el | 觸發菜單的元素 |
| pos.x | 菜單點擊時,鼠標位置相對於觸發元素的水平位移。 |
| pos.y | 菜單點擊時,鼠標位置相對於觸發元素的垂直位移。 |
| pos.docX | 菜單點擊時,鼠標位置相對於頁面的水平位移。 |
| pos.docY | 菜單點擊時,鼠標位置相對於頁面的垂直位移。 |
3.JEEGOOCONTEXT-Erik van den Berg
Project Page: http://www.planitworks.nl/jeegoocontext/
JEEGOOCONTEXT
菜單可以通過以下兩種方法初始化:
$('selector').jeegoocontext('menu_id');
$('selector').jeegoocontext('menu_id', 'options');
“selector”為菜單組建要綁定的內容,可以是任何jQuery選擇器。
“menu_id”為菜單ID(沒有 “#”)。
“options”為對象,可以配置屬性和回調函數。
所有菜單內容都可以從菜單解綁,只需調用:
$ ('context').nojeegoocontext();
Options properties:
| livequery | Boolean | undefined | Menu | 如為true, 菜單內容通過livequery生成並動態加載。 |
| hoverClass | String | ‘hover’ | Menu | 這個CSS類在鼠標懸停在菜單項或其直接子項時被設置。 |
| activeClass | String | ‘active’ | Global | 這個CSS類設置給當前活動的菜單 (右鍵點擊會彈出菜單的區域)。 這個變量是全局的,在使用多個菜單時只需要設置一次。如果重復設置,其值為最后提供的。 |
| menuClass | String | ‘jeegoocontext’ | Global | 所有的菜單都必須包含這個CSS類。這個變量是全局的,在使用多個菜單時只需要設置一次。如果重復設置,其值為最后提供的。 |
| autoAddSubmenuArrows | Boolean | true | Menu | 如為true,則自動為有子項的菜單項添加指示箭頭。 |
| submenuClass | String | ‘submenu’ | Menu | 如果autoAddSubmenuArrows為true, 這個類設置給菜單項中包含小箭頭的<span>元素。 |
| separatorClass | String | ‘separator’ | Menu | 當某個菜單項含有此類,則在按鍵盤上下鍵切換菜單項時,該菜單項被跳過。 |
| fadeIn | Number | 200 | Menu | 菜單和子級菜單淡入的時間,單位為毫秒。 |
| delay | Number | 300 | Menu | 鼠標移出父菜單項時,其子菜單隱藏的延遲時間,單位為毫秒。 |
| keyDelay | Number | 100 | Menu | 上下鍵切換菜單項的延遲時間,單位為毫秒。 |
| widthOverflowOffset | Number | 0 | Menu | 可以在寬度溢出時使用。例如設置為20時,菜單和子菜單的右部總是離窗口右邊界有20px的間距。 |
| heightOverflowOffset | Number | 0 | Menu | 可以在高度溢出時使用。例如設置為20時,菜單和子菜單的底部總是離窗口下邊界有20px的間距。 |
| submenuLeftOffset | Number | 0 | Menu | 子菜單相對於父菜單的水平位移。如為-3,每個子菜單左部將有3px與父菜單重疊。 |
| submenuTopOffset | Number | 0 | Menu | 子菜單相對於父菜單的垂直位移。如為-3,每個子菜單將比其父菜單項高出3px。當然,在高度溢出的情況下,此值被忽略。 |
| operaEvent | String | ‘dblclick’ | Menu | 在Opera的9.5以前老版本中瀏覽器右鍵菜單時是禁止重寫的,這個事件用來定義在Opera中如何打開菜單。 |
| event | String | undefined | Menu | 此項被設置時,定義的事件將用來取代右鍵打開菜單。優先於operaEvent屬性。例如,設置為’click’將使用左鍵打開菜單。 |
Options callbacks
可設置以下4個回調:
onShowonHoveronSelectonHide
每個回調接收兩個參數:e 和 context,e為該事件的來源元素,context為菜單彈出所在的區域。利用這些回調函數,可以用return false的方法取消菜單事件的默認行為。
| onShow | menu | Right-click on bound context. | 隱藏頁面上所有菜單。在頁面上刪除所有處於active的菜單及菜單項的active類。為當前點擊的內容添加active類。淡入菜單。 |
| onHover | menu-item | Mouseover on menu-item. | 定位並淡入子級菜單。 |
| onSelect | menu-item | Click on menu-item. | 刪除當前處於active的菜單或菜單項的active類。隱藏菜單。 |
| onHide | menu | Click on document. | 在頁面上刪除所有處於active的菜單及菜單項的active類。隱藏菜單。 |
4.JQUERY CONTEXT MENU SCRIPT-Dynamic Drive
Project Page: http://www.dynamicdrive.com/dynamicindex1/contextmenu.htm
jQuery Context Menu script
這也是一個簡單的右鍵菜單,菜單內容同樣用<ul>和<li>嵌套構造多級菜單。使用方法參看插件頁面。
5.CONTEXT MENU-Chris Domigan
Project Page: http://www.trendskitchens.co.nz/jquery/contextmenu/
ContextMenu plugin
這也是一個名為Context Menu的插件。
使用:
參數:
menu_id
通過引用菜單的ID,你可以在多個元素上綁定相同的菜單。如:
$("table td").contextMenu("myMenu")
將會把ID為”myMenu”的菜單綁定到所有的表格單元格上。
settings
settings支持以下屬性:
| bindings | 包含”id”:function對的對象。提供的函數為點擊時的動作。觸發菜單的元素作為第一個參數傳遞給該句柄。 |
| menuStyle | 包含styleName:value對的對象,定義菜單容器ul的樣式。 |
| itemStyle | 包含styleName:value對的對象,定義菜單項li的樣式。 |
| itemHoverStyle | 包含styleName:value對的對象,定義菜單項li的懸停樣式。 |
| shadow | 布爾值,默認為true。菜單是否顯示陰影。 |
| eventPosX | 允許你定義菜單彈出的位置,默認為pageX。IE6下需設置為clientX。 |
| eventPosY | 允許你定義菜單彈出的位置,默認為pageX。IE6下需設置為clientY。 |
| onContextMenu(event) | 在菜單顯示前調用。如果返回false,將不顯示菜單。 |
| onShowMenu(event, menu) | 在菜單顯示前調用。它將傳遞一個reference給菜單元素,並允許你在菜單顯示之前手動修改輸出,你可以在菜單顯示給用戶之前,顯示或隱藏參數或其他任何東西。該函數必須返回menu |
另外的,你可以調用:
$.contextMenu.defaults(settings)
為所有菜單定義一個默認樣式。

7.CONTEXTMENU-Xuanye
Project Page: http://code.google.com/p/xjplugin/source/browse/trunk/ControlsSample/Javascripts/Plugins/jquery.contextmenu.js
這是一個國人在另一個右鍵菜單腳本的基礎上,修改bug並jQuery插件化得到的插件……小巧易用,功能還不錯,菜單內容為json傳入,而不是把ul li格式化。
ContextMenu
話不多說,直接上Demo完整代碼。參數使用方法請看參看注釋和示例。
