    "!url": "http://api.jquery.com/jquery/",
    "!doc": "Return a collection of matched elements either found in the DOM based on passed argument(s) or created by passing an HTML string.",
    ...

Completion works for jQuery method :

        "!type": "fn(events: string, selector?: string, data?: ?, handler: fn(+jQuery.Event)) -> jQuery.fn",
        "!url": "http://api.jquery.com/on/",
        "!doc": "Attach an event handler function for one or more events to the selected elements."
      },
...

Tern is able to manage jQuery Event :

      "!url": "http://api.jquery.com/category/events/event-object/",
      "!doc": "The jQuery.Event constructor is exposed and can be used when calling trigger. The new operator is optional.",
      "prototype": {
        "currentTarget":{
          "!type": "+Element",
          "!url": "http://api.jquery.com/event.currentTarget/",
