Dynamic URL of TreeLoader in ColumnTree

[--jack]

Hi,

I have a textfield and columntree in a page. I want to construct the url for the TreeLoader based on the userinput in the textfield.

All the columntree examples I saw sets the loader and its url at the time of creation of the tree.

How can I dynamically change the loader URL for the columntree?

Also the tree should load its data only when the user enters a value in the textfield and clicks a button.

I tried setting

tree.loader.url = <new url>

in the button's click event and then tried

tree.loader.load(tree.root)

. But it didn't work.

Same problem here..

The API docs don't show a 'reload' function for the ColumnTree or it's loader.

I tried a few things without success like:

  var urlToLoad = '/admin/get-info.php?cname=' + node.id;
  columnTree.loader = new Ext.tree.TreeLoader({
                dataUrl: urlToLoad,
                uiProviders:{
                  'col': Ext.tree.ColumnNodeUI
                }
  });

Ok found the solution...

The root is an AsyncTreeNode as follows

root: new Ext.tree.AsyncTreeNode({
            text:'Info'
        })

and the API for AsyncTreeNode contains a 'reload' function that takes a callback function as a parameter.

This works for me:

columnTree.getRootNode().reload(null);
