Automatically update a Date Field when a Text Field has changed

[vanderLeest]

I want to set a Comment Date field to the current date time, when the associated Comment has been entered and/or updated on a Details Page of a Search and Report DataPage.

From code found in previous topics, I constructed the following JS script, but sadly it is not working. Any help will sincerely be appreciated
(as updating the field via a Table Trigger creates  too many cascading actions).

PS On the Stack Overflow site, I picked up the suggestion to add an eventlistener statement

MS_FSR_Comment is a TEXT (255) field with  Text Area on the Details page

MS_FSR_CommDt is a Date/Time field

 

<script>
document.getElementById("EditRecordMS_FSR_Comment").addEventListener("change", function(){

SetFSRDate;

});

Function SetFSRDate(){
var entered = document.getElementById("EditRecordMS_FSR_Comment").value;
    if (entered.length > 0) {
var currentdate = new Date();
var datetime = currentdate.getDate() + "/"
                + (currentdate.getMonth()+1)  + "/"
                + currentdate.getFullYear() + " "  
                + currentdate.getHours() + ":"  
                + currentdate.getMinutes() + ":"
                + currentdate.getSeconds();
document.getElementById('MS_FSR_CommDt').value = datetime;
}
}
</script>

I noticed one error in the script above: the field in the last line before </script> should  be referenced as 

document.getElementById("EditRecordMS_FSR_CommDt").value = datetime;

Even with this correction,  the MS_FSR_CommDt is not updated

I'm happy to answer my own topic.

the following script works:

document.getElementById("EditRecordMS_FSR_Comment").onchange = function(){

var entered = document.getElementById("EditRecordMS_FSR_Comment").value;
    if (entered.length > 0) {
var currentdate = new Date();
var datetime = currentdate.getDate() + "/"
                + (currentdate.getMonth()+1)  + "/"
                + currentdate.getFullYear() + " "  
                + currentdate.getHours() + ":"  
                + currentdate.getMinutes() + ":"
                + currentdate.getSeconds();
document.getElementById("EditRecordMS_FSR_CommDt").value = datetime;
}
};

And don't forget to set the receiving field to a Text field on the Report Details Page.

(if set as Display Only it cannot be updated)
