Trigger script if a value has changed in a field between when Editor being spawned to when updated?

imarder

When the Editor is spawned in Edit mode, I need a way of determining if a value has changed in a date field to another value after an update. I need to ultimately trigger a PHP script, this of course can be done via ajax, if need.

Is this best done, through the Editor events listener, like somehow comparing before and after values (I am not sure how to do that) or through DB queries and some magic in the table.???.php script? Again, not sure how to do that.

Thanks

Ignore and self answered. Found exactly what I was looking for

    var openVals;
    editor
        .on( 'open', function () {
            // Store the values of the fields on open
            openVals = JSON.stringify( editor.get() );
        } )
        .on( 'initSubmit', function () {
            closeVals = JSON.stringify( editor.get() );
            if ( openVals !== closeVals ) {
                   // read the required obj and execute script
                   console.log (closeVals);
            }
        } );

That will do nicely . dependent() would be another option to know when a value gets changed.
