globals/HTMLElement.prototype

Mocks of the lookup, visibility, style and event helpers Obsidian adds to HTMLElement.prototype.

Functions

Function	Description
find	Finds the first descendant matching a selector.
findAll	Finds every descendant matching a selector.
findAllSelf	Finds every element matching a selector, including the element itself.
hide	Hides the element by setting its inline display to none.
isShown	Checks whether the element is shown: attached to the DOM with no ancestor hidden by display: none. The mock relies on offsetParent, which jsdom leaves null, so it reports false unless a test defines offsetParent.
off	Removes a delegated event listener registered with on. As in Obsidian, every registration whose selector, listener and options are all identical to the ones given is removed.
on	Adds a delegated event listener, as Obsidian does: it is called only for events whose target, or an ancestor of it up to this element, matches selector, with that matching element as delegateTarget. The registration is kept in _EVENTS.
onClickEvent	Listens for clicks on the element. The mock registers a plain click listener, which cannot be removed.
onNodeInserted	Calls a listener when the element is inserted into the DOM. The mock observes nothing: it calls the listener once, immediately.
onWindowMigrated	Calls a listener when the element is migrated to another window. The mock never calls it, since tests have a single window.
setCssProps	Sets CSS properties, including custom properties such as --size, on the element’s inline style.
setCssStyles	Assigns camelCase style declarations to the element’s inline style.
show	Shows the element by clearing its inline display.
toggle	Shows or hides the element through its inline display.
toggleVisibility	Shows or hides the element through its inline visibility, so it keeps its place in the layout.
trigger	Dispatches a bubbling, cancelable event of the given type on the element.
