GM_context

A JavaScript library to create native HTML5 contextmenu in the browser. This library is designed for userscripts.

Compatibility

It uses native HTML5 <menu> and <menuitem> to build the context menu, so:

  1. It only works on latest Firefox.
  2. It doesn't replace the original context menu but extends it.

Usage

GM_context.add({
    context: ["image"],
    items: [{
        type: "submenu",
        label: "Reverse image search",
        items: [{
            label: "TinEye",
            onclick(e) {
                // ...
            }
        }, {
            type: "separator"
        }, {
            label: "Google",
            onclick(e) {
                // ...
            }
        }]
    }]
});

API reference

GM_context.add(options: object) -> menuId

Create a menu. options contain following properties:

  • context: array of string. A list of valid context type that the context menu should apply to. Possible values are:

    • page: when there is no other context type matched.
    • image: match images.
    • link: match links.
    • editable: match editable target.
    • selection: when part of the page is selected.

    If this property is missing, the menu is globally applied.

  • items: array of object. A list of items. See Define a menu item.

GM_context.remove(menuId)

Remove the menu.

Define a menu item

An item may have following properties:

  • checked: boolean. Only available to checkbox and radiogroups items.
  • disabled: boolean. To disable an item.
  • icon: string. Image URL, used to provide a picture to represent the command.
  • items: array of object. Define sub-items. Only available to submenu and radiogroup type. A submenu may contain any type of the items, but the items of radiogroup can only define label, checked, and value properties.
  • label: string. The label of the item. The label may contain a special string %s which would be replaced with the value of window.getSelection().
  • onclick: function. Called when the item is clicked. It would recieve a contextmenu event not a click event. Also, checkbox type items would recieve a boolean to indicate if the item is checked.

  • onchange: function. Only available to radiogroup. The handler would recieve following params:

    • contextmenu event.
    • The value of the item currently choosed.

  • type: string. Define different type of menuitem. Available values are:

    • checkbox: An item which can be checked/unchecked.
