SVGLengthList: initialize() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The initialize() method of the SVGLengthList interface clears all existing items from the list and re-initializes the list to hold the single item specified by the parameter. If the inserted item is already in a list, it is removed from its previous list before it is inserted into this list. The inserted item is the item itself and not a copy. The return value is the item inserted into the list.

Syntax

initialize(newItem)

Parameters

newItem: The SVGLength to add to the list.

Return value

The SVGLength that was added to the list.

Exceptions

NoModificationAllowedError DOMException: Thrown when the list is read-only.

Examples

See SVGLengthList for a complete example.
