Hello Guys/Gals,
One of me colleagues at work just called to check if i had a solution on an IE to firefox porting issue. Glad to know that commercial applns are now being forced the firefox way..:D. Will mention the challenge in brief :
35000 html pages javascript written for IE DOM based on IE
What would be the best way for me to port this IE based application to firefox such that we can use it from Linux as well as MS???. Are there any automated tools/parsers that i can make use of??.
None exist. You'd have to resort to one or a combination of the following: 1. When accessing IE specific object attributes, replace the object.property calls with a function call that returns a browser specific property.
2. On document load, add to the object's prototype those IE attributes that FF does not have.
Secondly, the other through process i had in mind was...if the first part isnt feasible can we build plugin the IE javas script and DOM model support into firefox as a plugin. This sounds ambitious but am just trying to explore some options out here where none seem to exist.
This is not really far fetched. I'm teaching myself the Firefox architecture, and aim to write similar FF extensions. There is a market for such extensions, and willing customers. Getting the app to a wider audience would have higher priority as compared to making the app cross browser compatible.
Just a tip: Before your colleague gets started with the migration, ask him to use Sahi (http://sahi.sourceforge.net/)to record the app's behaviour in IE. Then as they port the pages to FF/Safari, they could run Sahi tests to ensure that the application behaves as on Windows.
