JS-CheckForm

JS-CheckForm is a classic client-side form processor, a tool that checks what the user has entered inside a form's fields and shows a warning popup if undesired or missing data is found.

The script works totally inside the browser and can be a good safe-guard in case developers don't implement server-side form input checking systems.

All errors are displayed inside a classic alert box, quite obtrusive & blunt, but efficient nevertheless.

JS-CheckForm supports all the classic form elements, from text inputs, to textareas, checkboxes, radio buttons, and dropdown fields.

A demo is included with the download package, to help developers implement their own.

Requirements:

• JavaScript enabled on client side
