Add method: 1. Use the "parent node.append(child node)" statement; 2. Use the "parent node.prepend(child node)" statement; 3. Use "child node.appendTo(parent node) )" statement; 4. Use the "$(child node).prependTo(parent node)" statement.

In jquery, if you want to add child nodes to the parent node, there are many methods:
append(): to the "end" inside the selected element "Insert content.
