Handling itemclick event on tree panel Extjs 4

Question

what I am trying to do is to get different reaction on a different tree LEAF click!

var myTree = Ext.create('Ext.tree.Panel',
    store: store,
    rootVisible: false,   
    border: false,
    listeners: {
        itemclick: function(index) {            
            var record = store.getAt(index);
            alert(record);          
        }
    }
});

I tried with index, to get the index of leaf, nothing. I can get a reaction on a node click, but how to get a specific reaction on every leaf? I also tried giving ID to the leafs, no luck???

Maybe a simple example of

itemclick: function(Ext.view.View this, Ext.data.Model record, HTMLElement item, Number index, Ext.EventObject e) {  

}

Pleeasse help!!

Answer 1

The itemclick event listener's function param "index" does not point to your tree node's index. Like you mentioned in end of your question the syntax for the itemclick event is:

function(Ext.view.View this, Ext.data.Model record, HTMLElement item, Number index, Ext.EventObject e) {

}

Here is an example:

itemclick : function(view,rec,item,index,eventObj) {

    // You can access your node information using the record object
    // For example: record.get('id') or record.get('some-param')
    if(r.get('id')=='SP') {
        // I do my necessary logic here.. may be open a perticular window, grid etc..
    }

    if(r.get('id')=='CO') {
        // I do my necessary logic here.. may be open a perticular window, grid etc..
    }           
}

And here is an example of my tree node's data:

{ text: 'SP Reports', id: 'SP', leaf: true},
{ text: 'CO Reports', id: 'CO', leaf: true},
