JavaScript Form
The jSuites.form enhances a basic HTML form bringing various useful features when dealing with HTML forms and its elements. The most useful features are the following:
- Tracking any updates (Are you sure)?: It alerts the user before leaving a page when he has unsaved changes in one form.
- jSuites.validations: Create basic and custom input validations using the element properties.
- Data management: It loads data from a remote server to the form elements, and post data for a remote server for persistance.
- Events: Intercept and update the submission, create rules and callbacks.
- Upload: Integrates with jSuites.files to help upload files to the backend.
Features
Tracking the HTML form updates
Before the user leave a page with unsaved changes in a form. The javascript plugin creates a hash based on all form elements and its values. Before the user leaves the page, the tracker will recheck if there were changes in the hash. If the hash is different, the plugin will trigger an alert to the user because there were changes in the form, not saved yet.
It has a very optimized algorithm that works even with dynamic elements and provides a few methods to help the developer to enrich their applications.
JavaScript Form validations
Control the form validations from the HTML elements.
