However publication connected…
Agelong, accurate reply:
You besides don’t privation to entertainment this communication once the person hasn’t modified thing connected your kinds. 1 resolution is to usage the beforeunload case successful operation with a “soiled” emblem, which lone triggers the punctual if it’s truly applicable.
var isDirty = relation() { instrument mendacious; } framework.onload = relation() { framework.addEventListener("beforeunload", relation (e) { if (formSubmitting || !isDirty()) { instrument undefined; } var confirmationMessage = 'It seems to be similar you person been enhancing thing. ' + 'If you permission earlier redeeming, your adjustments volition beryllium mislaid.'; (e || framework.case).returnValue = confirmationMessage; //Gecko + I.e. instrument confirmationMessage; //Gecko + Webkit, Safari, Chrome and so on. }); };

You tin usage jQuery and signifier serialization, however this attack has any flaws. Archetypal you person to change the codification to activity connected immoderate signifier ($("signifier").all() volition bash), however the top job is that jQuery’s serialize() volition lone activity connected named, non-disabled components, truthful altering immoderate disabled oregon unnamed component volition not set off the soiled emblem. Location are workarounds for that, similar making controls readonly alternatively of enabling, serializing and past disabling the controls once more.
Truthful occasions look the manner to spell. You tin attempt listening for keypresses. This case has a fewer points:
- Gained’t set off connected checkboxes, energy buttons, oregon another components that are being altered done rodent enter.
- Volition set off for irrelevant keypresses similar the Ctrl cardinal.

And once you privation to instrumentality much behaviour, similar ignoring definite parts, you’ll person equal much activity to bash.
Don’t reinvent the machine:
Truthful earlier you deliberation astir implementing these options and each required workarounds, recognize you’re reinventing the machine and you’re inclined to moving into issues others person already solved for you.
If your exertion already makes use of jQuery, you whitethorn arsenic fine usage examined, maintained codification alternatively of rolling your ain, and usage a 3rd-organization room for each of this.
jquery.soiled (steered by @troseman successful the feedback) offers capabilities for decently detecting whether or not a signifier has been modified oregon not, and stopping the person from leaving the leaf piece displaying a punctual. It besides has another utile features similar resetting the signifier, and mounting the actual government of the signifier arsenic the “cleanable” government. Illustration utilization:
