A Final Word

In this column we covered in depth the DOM's different methods for creating nodes and assembling DOM trees. We showed you how to create HTML tag nodes as well as text nodes, and how to clone them. We demonstrated how to assemble a table with three different methods. We assembled the tree from top to bottom with the appendChild method, which appends a child to an existing list of children. We built the tree bottom up with the applyElement method, which establishes a father-son relationship after the target father is stripped from his existing children and father. The insertBefore method works exactly like the appendChild. In this column you learned:

• How to clone an existing node
• How to append a child to a father
