Why can't determine the specified node is leaf or not

[nyr_jack]

js code:
for(var i = 0; i < nodes.length; i++){
     alert($('#orgTree').tree('isLeaf',nodes));
//......
}
json code:
[{
   "id":1,
   "text":"root",
   "children":[{
      "id":2,
      "text":"node2",
      "checked":false
   },{
      "id":3,
      "text":"branch",
      "state":"open",
      "children":[{
         "id":4,
         "text":"branch1",
         "checked":false
      },
      {
         "id":5,
         "text":"branch2",
         "checked":false      
      },
      {
         "id":6,
         "text":"3",
         "checked":false      
      }]
   }]
}]

There are some errors in your code. Try the following code.

Code:

for(var i = 0; i < nodes.length; i++){
     alert($('#orgTree').tree('isLeaf',nodes[i].target));
//......
}
