g_form.setReadOnly() method not working when I run it through Client Script, but it works when I run the same on the JavaScript Executor(Ctrl + Alt + Shift + J), is there a way to debug and know what is stopping my Client Script code to not work on setting the field read only.

Hi,

This could be for many reasons. As Derek asked...please include your script otherwise we're all speculating and wasting time.

It could be other conflicting client scripts or UI policies that you have.

Please mark reply as Helpful/Correct, if applicable. Thanks!

add this line before setting readonly 

g_form.setMandatory(item, false);
