Ext.History is a small class that was released with ExtJS 2.2, making it easy to use the browser's back and forward buttons without breaking your AJAX-only pages.

ExtJS has several built-in Container classes - classes which can contain one or more other Ext.Components (such as Grids, Forms, other Panels, etc).

One of the more mesmerizing websites I've worked on recently was for a lingerie boutique in the UK.

This applies to ExtJS 2.2, the most current version as of the time of writing.

Ext.apply is one of those magic Ext JS methods which copies the essence of one object onto another.

So it came to be realised during Rails Camp 08 that the world was sadly lacking in William Shatner based list apps.

A lot of what we do in Rails boils down to simple Crud.

One of my recent Ext JS forms had a section which looked like this: items: [ new Ext.Button({ text: 'Preview Video', iconCls: 'play', handler: function() { var win; if (!

While creating an ExtJS form with several radio buttons today I ran into a bug which caused none of them to work as expected, even though there were no errors/exceptions.

I received an unhelpful error while trying to push to a repository on Github today: git push To git@github.com:user/repo.git !

Having recently made the switch from svn to git, I wanted to achieve what svn externals did (and what Piston did better).

If you're using Edge Rails (or > 2.1, which isn't out at time of writing), and are using the EXT JS framework anywhere, here are a couple of handy javascript include tag expansions to clean up your views.

Something that's harder than it should be is populating an EXT edit form with form data, where one of the form fields is a select box.

A problem that has recently had me pulling my hair out is how to save state in an EXT PagingToolbar.

If you're using edge rails you may have noticed that you can now define your own JavaScript expansions (if you're not on edge this will be included in the imminent 2.1 release).
