DomUtil

Utility functions to work with the DOM tree, used by Leaflet internally.

Methods

Method	Returns	Description
`get( <String or HTMLElement> id )`	`HTMLElement`	Returns an element with the given id if a string was passed, or just returns the element if it was passed directly.
`getStyle( <HTMLElement> el, <String> style )`	`String`	Returns the value for a certain style attribute on an element, including computed values or values set through CSS.
`getViewportOffset( <HTMLElement> el )`	`Point`	Returns the offset to the viewport for the requested element.
`create( <String> tagName, <String> className, <HTMLElement> container? )`	`HTMLElement`	Creates an element with `tagName`, sets the `className`, and optionally appends it to `container` element.
`disableTextSelection()`	-	Makes sure text cannot be selected, for example during dragging.
`enableTextSelection()`	-	Makes text selection possible again.
`hasClass( <HTMLElement> el, <String> name )`	`Boolean`	Returns `true` if the element class attribute contains `name`.
`addClass( <HTMLElement> el, <String> name )`	-	Adds `name` to the element's class attribute.
`removeClass( <HTMLElement> el, <String> name )`	-	Removes `name` from the element's class attribute.
`setOpacity( <HTMLElement> el, <Number> value )`	-	Set the opacity of an element (including old IE support). Value must be from `0` to `1`.
`testProp( <String[]> props )`	`String` or `false`	Goes through the array of style names and returns the first name that is a valid style name for an element. If no such name is found, it returns `false`. Useful for vendor-prefixed styles like `transform`.
`getTranslateString( <Point> point )`	`String`	Returns a CSS transform string to move an element by the offset provided in the given point. Uses 3D translate on WebKit for hardware-accelerated transforms and 2D on other browsers.
`getScaleString( <Number> scale, <Point> origin )`	`String`	Returns a CSS transform string to scale an element (with the given scale origin).
`setPosition( <HTMLElement> el, <Point> point, <Boolean> disable3D? )`	-	Sets the position of an element to coordinates specified by `point`, using CSS translate or top/left positioning depending on the browser (used by Leaflet internally to position its layers). Forces top/left positioning if `disable3D` is `true`.
`getPosition( <HTMLElement> el )`	Point	Returns the coordinates of an element previously positioned with `setPosition`.

Properties

Property	Type	Description
`TRANSITION`	`String`	Vendor-prefixed transition style name (e.g. `'webkitTransition'` for WebKit).
