How do I get Started?

The Getting Started Guide

General issues

My code links to extjs.com/s.gif

Somewhere at the top of your code you should place a line like the following one, that tells Ext where to find the empty image it needs for some widgets (preferably from your own server/domain). Modify the URL as needed:

This cannot be preset to a value that exists on your server. We cannot predict where you will place your image directory!

Ext.BLANK_IMAGE_URL = '/images/ext/resources/images/default/s.gif';  // Ext 2.0
Ext.BLANK_IMAGE_URL = '/images/ext/resources/images/aero/s.gif';  // Ext 1.1

You can also read about it in the documentation.

Ext does not work over HTTP, but does work locally

Rarely, there is an issue with Apache cutting off lengthy files — ext-all.js can get cut off mid-stream, which can lead to strange errors over HTTP while things work just fine served locally. There are various potential causes. See this forum thread for additional discussion and potential solutions.
