Range.insertNode() 是在Range的起始位置插入节点的方法。

新节点是插入在 the Range起始位置。If the new node is to be added to a text Node, that Node is split at the insertion point, and the insertion occurs between the two text nodes.

If the new node is a document fragment, the children of the document fragment are inserted instead.
