SVGLengthList: replaceItem() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The replaceItem() method of the SVGLengthList interface replaces an existing item in the list with a new item. If the new 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. If the item is already in this list, note that the index of the item to replace is before the removal of the item.

Syntax

js
replaceItem(newItem, index)

Parameters

newItem

The SVGLength to add to the list.

index

A non-negative integer that specifies the index of the item to delete.

Return value

The SVGLength that was added the list.

Exceptions

DOMException NoModificationAllowedError

Thrown when the list is read-only.

DOMException IndexSizeError

Thrown when the index is out of bounds for the list.

Examples

See SVGLengthList for a complete example.
