You can add custom behaviors by adding JavaScript to your form/flow. For example, you may want to change the look of your form's submit button when the user hovers the mouse over the button. It is possible to associate a custom JavaScript handler to any form control. See Custom JavaScript Examples for sample code. | Warning |

Although JavaScript will accomplish the task, it is important to note that your scripts are not subjected to formal testing by the frevvo quality assurance team. Choosing an approach that is part of the product like Business Rules is a better choice than adding JavaScript since released versions undergo rigorous quality assurance testing. Customizations using JavaScript should only be used under special situations and if there is no other way to customize the form to the requirements. For example, let's say you have a message control in your form that contains markup to pull a custom JavaScript. The URL for the script contains the home directory and revision number - (http://localhost:8080/frevvo/js-24487/libs/script.js). An upgrade of to new release or revision version could potentially stop the form from working. If you choose to add JavaScript, we strongly recommend that you are familiar with a JavaScript debugger / web development tool such as the Firebug extension for Firefoxfor your browser. |
