REQUIREMENTS

jQuery 1.7+

USAGE

It is quite straightforward. Simplest usage is

$(document).ready(function() {
	$("form").formSavior();
});

Use any selector for 'form' or just leave it as is and it will apply the check for all the forms on the page. See, Simple!

The plugin has two options

• msg, to customize your message for each form. Its usage is shown below.
• noprompt, a class to add to links or buttons to cancel out of the form without saving, like a Cancel button. Default class is 'fs_noprompt'

Sample code with 'msg' option:

$(document).ready(function() {
	$("#personInfo").formSavior({
		'msg' : 'Personnel information changes have not been saved.'
	});
});
