using javascript add a new treenode to a treegrid (not c# code Behind),How can I do?

Thanks

[huchaonian]

c # is written like this

             Ext.Net.TreeNode zxsnode = new Ext.Net.TreeNode();

            zxsnode.NodeID = bmbhstr;
            zxsnode.Text = bmmcstr;


            zxsnode.CustomAttributes.Add(new ConfigItem("bmbh", bmbhstr, ParameterMode.Value));
            zxsnode.CustomAttributes.Add(new ConfigItem("bmmc", bmmcstr, ParameterMode.Value));
            zxsnode.CustomAttributes.Add(new ConfigItem("sfxm", sfxmstr, ParameterMode.Value));

Javascript so it?
