SVGNumberList: replaceItem() method

The replaceItem() method of the SVGNumberList 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

Parameters

• newItem
  • : The SVGNumber to add to the list.

• IndexSizeError DOMException
  • : Thrown when the index is out of bounds for the list.
