The `Ext.create` function yields a constructor rather than an object as

Ext.application({
        name: 'example',
        launch: function() {
            var panel = Ext.create('Ext.panel.Panel', {
                id:'myPanel',
                renderTo: Ext.getBody(),
                width: 400,
                height: 200,
                title: 'Example Panel'
            });

            //issue here
            panel.update();

I encountered an error displayed in the console:

Uncaught TypeError: Object [object Object] has no method 'update'

When inspected through a debugger, I noticed that the variable 'panel' is of type 'constructor.'

panel:constructor

This explains why the 'update' method is not available. It seems odd to me that I am referencing a constructor function instead of a newly created object.

The same situation arises when creating other objects from ExtJs core classes.

Is this possibly related to my project's structure?

P.S. My knowledge of JavaScript is limited, so it is possible that the issue lies in my understanding of fundamental concepts.

Answer №1

One issue is that the grid doesn't have a designated reload function; instead, loading is managed by the store. To refresh the grid, you should use grid.getStore().load();

In order to resolve this problem, it's important to refer to the documentation where you'll find that a reload method does not exist for grids.
