Hi all, I have been using Ext and jQuery for a few weeks now. One issue with this combination is the sheer volume of JavaScript and CSS that needs to be used. Because I am working with a large application I have been experiementing with different techniques to improve performance, minimizing the download of JS and CSS. To read about my experiences and a new technique I am using you can view explanations and examples on my blog: http://matthew.delmarters.com/weblog/injecting-javascript-and-css-into-iframes/
The core technique that I am experimenting with is "code injection" - effectively allowing you to download the JavaScript and CSS once and then reuse it by injecting it into Iframes. This solution is targeted at Web Applications which commonly use Iframes for complex layouts and to control memory usage in larger apps without moving to the complexity of a Single Page Interface (SPI). I also summarize and explain other methods available to developers for minimising their code and speeding up the loading time of their application. I thought people on this list may like to read about the techniques available, especially if they are using Ext like I am. I would also like to get some perspective on the "injection" concept by seeing what other developers think of it... Regards, Matthew
