ExtJS tree loading (change proxy url)

votes

I have Ext.tree.Panel and I use Ext.data.TreeStore for my tree.

var storeTree = Ext.create('Ext.data.TreeStore', {
    expanded: false,
    proxy: {
        type: 'ajax',
        url: '/tree'
    },
    root: {
        text: 'Ext JS',
        id: 'src',
        expanded: true
    },
    folderSort: true,
    sorters: [{
        property: 'text',
        direction: 'ASC'
    }]
});

Everything works!

But I need now something like that: at the first time, when I open page, when my tree will be loaded, I need to get JSON Tree from the another location (For example , first time I want to get JSON from /tree1 and then , when I expand my tree, to get from /generalTree);

In the other words, At the first time, I want to load tree from anotther JSON. I don't know now. Or may I send parameter , to the server, which will tell it, that it is first time of using tree (Hey, server, tree is expanded automatically by me, not from user clicking)

You can call the load method on the store and use another url for the request or add parameters:

// different URL
storeTree.load({
    url: '/treeinit'
});

// parameters
storeTree.load({
    params: {
        init: true
    }
});

Solution in Ext.tree.Panel

listeners : {

        beforeload: function ( th, records, successful, operation, eOpts ){
          console.log("load");
          storeTree.getProxy().extraParams.().extraParams.changableParam  = 'second';
          storeTree.getProxy().url = '/another url';
        }

}
