  • 项目

Adds a TREENODE at the given Integer index.

Syntax

object.addAt(index, node)

Parameters

index Required. Index at which to add the TREENODE.
node Required. The TREENODE to add.

Return Value

Remarks

When applied to the TREENODE element, the node is a child node of the TREENODE. When applied to the TREEVIEW element, the node is a root node.

This example creates a TREENODE root element. It assumes that the treeview has an id value of treeview_one.

var myNode = treeview_one.createTreeNode();

myNode.setAttribute("text", "My New Root Node");

treeview_one.addAt(0, myNode);

You can also place the value of the index into a string, as in the following example.

var myNode = treeview_one.createTreeNode();

myNode.setAttribute("text", "My New Root Node");

treeview_one.addAt("0", myNode);
