How to check if the value of an element has been changed?

How do I check if the value of a Html.EditorFor element has changed using Javascript or jQuery?
@Html.EditorFor(model => model.AddressPhysical1, new { htmlAttributes = new { @class = "form-control", id = "AddrPhys1", @onload = "TrackChanges(this.value)" } })
$(document).ready(function TrackChanges() {
var address = $('#AddressPhysical1').val();
$('#AddressPhysical1').keyup(function() {
if ($('#AddressPhysical1').val() != content) {
content = $('#AddressPhysical1').val();
alert('Content has been changed');
}
});
});

You have given the inputid = "AddrPhys1", so for a start you need to replace$('#AddressPhysical1')with$('#AddrPhys1'). And where have you declaredcontent(or did you meanaddress)?

Also note theTrackingChanges()function is not in scope of theonloadattribute, so that will be causing an error.

$(document).ready(function TrackChanges()=> this is not a proper way to declareonloadevent handler function. Just usefunction TrackChanges()and put the$(document).ready()inside it.

thank you for pointing that out @StephenMuecke , it seems to be getting the value now. What I am trying to do is show a list of all the changed values in a popup before hitting the submit button.

Then the correct approach would be to handle your forms.submit()event, then check thedefaultValuevs thevalueor each input (certainly not in a.keyup()event)
