推荐答案

从DOM中删除表单的实例，那是。你不必删除任何东西;删除的对象和资源通过垃圾回收回收。要删除元素，请使用以下方法：

Node.removeChild （） - Web API | MDN [ ^ ]。



使用jQuery，您可以使用以下函数： DOM删除| jQuery API文档 [ ^ ]。

参见：操纵| jQuery API文档 [ ^ ]。

Remove the instance of a form from the DOM, that's is. You don't have to "delete" anything; the objects deleted and resources are reclaimed via garbage collection. To remove an element, use this method:
Node.removeChild() — Web APIs | MDN[^].

With jQuery, you can use these functions: DOM Removal | jQuery API Documentation[^].
