Radio Buttons Creating Time Stamps?

[jonathannel]

Good Morning All,

I've searched but can't find anyone asking about a way to use radio buttons to create a visible time/date stamp. Right now, I am using a form log where radio buttons are used for showing start and completion of a task. Currently the creation of the task log "created" is being used for a start time and "modified" is being used for an end time, however in situations where a task is complete but the record needs adjustment after the fact, the "modified" time does not work.

Is there a way to have when the radio button is selected a time/date stamp is recorded visibly?

Thanks

Yes! You can achieve this in ServiceNow by using Client Scripts to capture timestamps when a radio button is selected and store them in visible fields.

✅ Solution Approach

1. Add two new date/time fields (start_time and completion_time) to the form.
2. Use an onChange Client Script to capture the timestamp when the user selects a radio button.

✅ Final Client Script

js

CopyEdit

(function executeRule(current, gForm, gSNC) { var selectedValue = gForm.getValue('radio_button_field'); // Replace with actual field name var currentTime = new Date().toISOString(); // Get current timestamp in UTC format if (selectedValue === 'start') { gForm.setValue('start_time', currentTime); // Set Start Time } else if (selectedValue === 'completed') { gForm.setValue('completion_time', currentTime); // Set Completion Time } })(current, gForm, gSNC);

🔹 Steps to Implement:

1. Navigate to your ServiceNow instance.
2. Go to "Client Scripts" (System Definition > Client Scripts).
3. Create a new Client Script with:
   • Type: onChange
   • Table: Your target table (e.g., task_log)
   • Field: Your radio button field (radio_button_field)
   • Script: Copy & paste the above script.
4. Save & Test 🚀

🔹 How It Works:

✔ When "Start" is selected, the Start Time field is updated.
✔ When "Completed" is selected, the Completion Time field is updated.
✔ The timestamp remains unchanged even if modifications occur later.

This way, you get a reliable time log for task completion without relying on "modified" timestamps.
