Return extra data besides tree data from ExtJS TreeLoader dataUrl?
- by Chad Johnson
I asked this question in the Ext JS forums, but I received no responses, so I am asking here.
I have a TreePanel (code below) that uses a TreeLoader and an AsyncTreeNode. In my API method specified by the TreeLoader's dataUrl, I return a JSON array to populate the tree.
This works great, of course. However, I need to return an additional item--an integer--in addition to the array, and I need to display that value somewhere else in my UI. Is this possible? If not, what else would be a good solution?
Here's the code I have currently:
tree = new Ext.tree.TreePanel({
enableDD: true,
rootVisible: false,
useArrows: true,
loader: new Ext.tree.TreeLoader({
dataUrl: '/api/method'
}),
root: new Ext.tree.AsyncTreeNode()
});
