The removeChild method development sample code in JavaScript, removechild

1. Overview

Although the deleted node is not in the document tree, it is still in the memory and can be added to another location at any time.

When you traverse a child node of a parent node and delete it, note that the children attribute is a read-only attribute and will be updated in real time when the child node changes.

// Get the node to be deleted: var self = document. getElementById ('to-be-removed'); // obtain the parent node: var parent = self. parentElement; // Delete: var removed = parent. removeChild (self); removed = self; // true
