Ext.onReady() vs $(document).ready()

Question

Whats the difference? I have on $(document).ready function which should check if extjs is loaded but the main problem is extjs does not load on time and things inside $(document

Answer 1

They both check for when the DOM is ready. If you need Ext to be loaded when using jQuery, try to invert the logic (don't know if it will work, haven't tried).

Ext.onReady(function() {
    $(document).ready(function() {
        Ext.create('Ext.Button', {...});
    });
});
