If you can write it (correctly ;-), it will work!
Integrify doesn't so much work with JavaScript rather it stores whatever you write and displays it in the browser when a form is presented to the user. When JavaScript executes it is a function of the Web browser, not Integrify. The Integrify product does not handle the execution of your JavaScript in any fashion; rather Integrify stores whatever you save in your form to the database and when that form is presented to the user as request is executing, Integrify simply returns to the browser whatever you have saved. The Web browser takes over at that point and based on what is written will execute the JavaScript.
Integrify Professional Services and Support has seen everything from a very simple pop-up alert window to prompt a user to AJAX integration to read remote services that does complex searches and data retrievals. Because of this unique customization for each client, it is not possible for Integrify Support to troubleshoot JavaScript related issues. We do however post tips/tricks from time-to-time in our Integrify community area. Please check out the Community for tips/tricks and other references.
