Function $

Parameters

• n: string | HTMLElement | Event | Event<unknown>

  the object to look for. If it is a string, it is assumed to be UUID, unless it starts with '$'. For example, zkbind.$('uuid') is the same as zkbind.$('#uuid'), and both look for a widget whose ID is 'uuid'. On the other hand, zkbind.$('$id') looks for a widget whose ID is 'id'.
  and zkbind.$('.className') looks for a widget whose CSS selector is 'className'.
  If it is an DOM element (DOMElement), it will look up which widget it belongs to.
  If the object is not a DOM element and has a property called target, then target is assumed. Thus, you can pass an instance of jq.Event or zk.Event, and the target widget will be returned.

• Optional opts: BinderOptions

  the options. Allowed values:

  • exact - id must exactly match uuid (i.e., uuid-xx ignored). It also implies strict
  • strict - whether not to look up the parent node.(since 5.0.2) If omitted, false is assumed (and it will look up parent).
  • child - whether to ensure the given element is a child element of the widget's main element (zk.Widget.$n). In most cases, if ID of an element is xxx-yyy, the the element must be a child of the element whose ID is xxx. However, there is some exception such as the shadow of a window.
