read only after input in text field.

[Robert22159663q23h]

I have text fields set to input the time when it is clicked.

Is there a way to make the text field read only after the time is in.

event.value = util.printd('hh:MM', new Date());

current code to insert time when text field is clicked

Thanks

sorry this is the code

event.target.value = util.printd('hh:MM', new Date());

Add this to the end of the code:

event.target.readonly = true;
