Making all the fields non editable except one in Client Script

[aditiojha]

I am making entire form read only on a condition with a on load client script with code as below :

var fields = g_form.getEditableFields();

for (var x = 0; x < fields.length; x++) {

        g_form.setReadOnly(fields[x], true);

}

This is because i have lot of conditional hide and display on form.

Now the requirement is to make one single field editable on that condition.

Can i achieve this using same client script or creating something new but keeping this Client Script.

When i am adding a line to make the field mandatory in same Client Script. The Client Script is not working at all.

Is this still a valid glideform api?  It's not on the developers reference anymore:

there are many functions which are undocumented and developers are still using it
