function examples

1. Get the node data for tId = "Tree_10"

Gets all child node IDs under the current node

The code is as follows

Copy Code

var setting = { Data: { Simpledata: { enable:true } }, View: { Showicon:false p>}, callback:{ Onclick:function ztreeonclick (event, Treeid, TreeNode) { Alert (Treenode.tid + "," + Treenode.name+ "," +treeid); Var ids=[]; Ids=getchildren (Ids,treenode);    }     }, Check: { Enable:true, Autochecktrigger:false, chkboxtype:{"Y": "PS", "N": "PS"} }   };   //ids is an array that returns an array of results TreeNode is the selected node Function GetChildren (ids,treenode) { Ids.push (treenode.id);  if (treenode.isparent) { for (Var obj in Treenode.children) { GetChildren (ids,treenode.children[ OBJ]); } }  return IDs; }
