Items
The items map contains the commands to list in the menu. Each command has a unique key identifying an item object. The value may either be an item (properties explained below), or a string (which will insert a separator, disregarding the string's content). It is also possible to define a seperator the same as an item, and use the type:cm_seperator to define it.
var items = {
firstCommand: itemOptions,
separator1: "-----",
separator2: { "type": "cm_seperator" }
command2: itemOptions
}
options.items
name
Specify the human readable name of the command in the menu. This is used as the label for the option.
name: string
Example
var items = {
firstCommand: {
name: "Copy"
}
}
callback
Specifies the callback to execute if clicked on
The Callback is executed in the context of the triggering object. The first argument is the key of the command. The second argument is the options object. The Callback may return false to prevent the menu from being hidden.
If no callback and no default callback is specified, the item will not have an action
callback: function(itemKey, opt)
Example
var items = {
firstCommand: {
name: "Copy",
callback: function(itemKey, opt){
// Alert the key of the item and the trigger element's id.
alert("Clicked on " + itemKey + " on element " + opt.$trigger.id);
// Do not close the menu after clicking an item
return false;
}
}
}
className
Specifies additional classNames to add to the menu item. Seperate multiple classes by using spaces.
className: string
Example
var items = {
firstCommand: {
name: "Copy",
className: 'contextmenu-item-custom contextmenu-item-custom__highlight'
}
}
icon
Specifies the icon class to set for the item.
When using a string icons must be defined in CSS with selectors like .context-menu-item.context-menu-icon-edit, where edit is the icon class specified.
When using a callback you can return a class string to use that as the class on the item. You can also modify the element by using the $itemElement argument.
icon: string or function(opt, $itemElement, itemKey, item)
Example
var items = {
firstCommand: {
name: "Copy",
icon: function(opt, $itemElement, itemKey, item){
// Set the content to the menu trigger selector and add an bootstrap icon to the item.
$itemElement.html('<span class="glyphicon glyphicon-star" aria-hidden="true"></span> ' + opt.selector);
// Add the context-menu-icon-updated class to the item
return 'context-menu-icon-updated';
}
},
secondCommand: {
name: "Paste",
icon: "paste" // Class context-menu-icon-paste is used on the menu item.
}
}
disabled
Specifies if the command is disabled (true) or enabled (false).
May be a callback returning a boolean. The callback is executed in the context of the triggering object (so this inside the function refers to the element the context menu was shown for). The first argument is the key of the command. The second argument is the options object.
disabled: string or function(itemKey, opt)
Example
var items = {
firstCommand: {
name: "Copy",
disabled: function(key, opt){
// Disable this item if the menu was triggered on a div
if(opt.$trigger.nodeName === 'div'){
return true;
}
}
}
}
visible
Specifies if the command is visible (true) or not (false).
May be a callback returning a boolean. The callback is executed in the context of the triggering object (so this inside the function refers to the element the context menu was shown for). The first argument is the key of the command. The second argument is the options object.
disabled: string or function(itemKey, opt)
Example
var items = {
firstCommand: {
name: "Copy",
visible: function(key, opt){
// Hide this item if the menu was triggered on a div
if(opt.$trigger.nodeName === 'div'){
return false;
}
}
}
}

items: {
// <select>
select: {

height
The height in pixel <textarea> element. If not specified, the height is defined by CSS.

items
Commands to show in a sub-menu. You can nest as many as you like.
items: object

$.contextMenu({

name: "Textarea",

callback: function(key, opt){
alert("Clicked on " + key);
}
}
}
}
}
}
});
accesskey
Character(s) to be used as accesskey.
Considering a b c $.contextMenu will first try to use »a« as the accesskey, if already taken, it'll fall through to »b«. Words are reduced to the first character, so »hello world« is treated as »h w«.
Note: Accesskeys are treated unique throughout one menu. This means an item in a sub-menu can't occupy the same accesskey as an item in the main menu.
accesskey: string
Example
$.contextMenu({
selector: 'span.context-menu',
accesskey: 'a'
callback: function(itemKey, opt){
alert('I pressed a!');
}
});
