How to show oldValue and newValue in alert everytime if I change state field on incident form?

[NishantDhole]

Hi,

Please find below scenario: 

On Incident form,

if state field old value is New|1 and I change it to inProgress|2, then it should popup an alert as old value : New|1 and new value: inProgess|2. 

 Now, if I change state field New|1 again then it should be alerted like oldValue: inProgress|2 and newValue : New|1

Note: Form should not be saved. It should be achieved by without saving form.

For above use case please find below solution :

We need to write on load client script on incident table :

function onLoad() {
    //Type appropriate comment here, and begin script below
    var oldStateValue = g_form.getValue('state');

    function showAlert() {
        var newStateValue = g_form.getValue('state');
        alert('Old State: ' + oldStateValue + '\nNew State: ' + newStateValue);
        oldStateValue = newStateValue;
    }
    g_form.getControl('state').addEventListener('change', showAlert);
}
