Could we set read only for field by Javascript?

I want to make the field to be read only or not by a button, however instead of using XML, I would like to make it run by Javascritpt.
Can it be possible ?

Hi,
It is possible to make the field read-only through Javascript. It can be done as follows
document.getElementById('field_id').setAttribute('readonly', true);
In these cases, we have to use the setAttribute method. Here, with the help of the field's id, we can set the readonly as true. We have to replace the field_id with our corresponding id.
Regards
