AEM 6.3 - Coral Select List, How to get previously selected value on change event.

I have a progressive drop down in my dialog. My requirement is to get previously selected value on change event.

Basically, I want's to show confirmation box to the user only if he selected a different value. And if the user clicks on the cancel button, the previous value should be automatically selected.

Demo : Dropbox - Jun-28-2018 12-32-23.mp4

Hi,

You can do this by using jquery, below is the sample code snippet to get previous value  from dropdown

(function () {
   var previous;

  $("select").on('focus', function () {
   // Store the current value on focus and on change
  previous = this.value;
   }).change(function() {
   // Do something with the previous value after the change
  alert(previous);

   // Make sure the previous value is updated
  previous = this.value;
   });
})();

Thanks
