Ext JS 3 to Ext JS 4 migration issue

Question

我想将基于Ext JS 3的代码迁移到Ext JS4。Ext JS 3中有类Ext.Updater，在Ext JS 4中找不到此类功能。也许有人可以帮助我吗？

Answer 1

Actually a successful migration is never promised by officially. But if you still want to migrate, you can follow this guide .

Answer 2

EXT 4.x has Ext.ElementLoader which has similar capabilities to update the element using ajax calls. Take a look at it.

Hope this is what you were looking for.
