特性

特性	类型	描述
MutationRecord.type	字符串	返回 "attributes" if the mutation was an attribute mutation, "characterData" if it was a mutation to a CharacterData node, and "childList" if it was a mutation to the tree of nodes.
MutationRecord.target	节点	Returns the node the mutation affected, depending on the MutationRecord.type . For 属性 , it is the element whose attribute changed. For characterData , it is the CharacterData 节点。 For childList , it is the node whose children changed.
MutationRecord.addedNodes	NodeList	Return the nodes added. Will be an empty NodeList if no nodes were added.
MutationRecord.removedNodes	NodeList	Return the nodes removed. Will be an empty NodeList if no nodes were removed.
MutationRecord.previousSibling	节点	Return the previous sibling of the added or removed nodes, or null .
MutationRecord.nextSibling	节点	Return the next sibling of the added or removed nodes, or null .
MutationRecord.attributeName	字符串	Returns the local name of the changed attribute, or null .
MutationRecord.attributeNamespace	字符串	Returns the namespace of the changed attribute, or null .
MutationRecord.oldValue	字符串	The return value depends on the MutationRecord.type . For 属性 , it is the value of the changed attribute before the change. For characterData , it is the data of the changed node before the change. For childList , it is null . Note that for this to work as expected, attributeOldValue or characterDataOldValue must be set to true in the corresponding MutationObserverInit parameter of the MutationObserver observe 方法
