Hello I created a button to lock all fields once pressed with the script. When I press it nothing happens.

// Lock all fields in the form
var allFields = this.getFieldNames();
for (var i = 0; i < allFields.length; i++) {
this.getField(allFields[i]).readonly = true;
}

Can someone help.? I would also need to unlock to make edits.

Thank you.

Change the word true in the script to false. You would have to exclude the unlocking button field from the original script or else it would be locked ("readonly") and wouldn't work.

this.getFieldNames() is not a function. Try this:

for(var i = 0; i < this.numFields; i++)
{
var fieldName = this.getNthFieldName(i);
var oFld=this.getField(fieldName);
if(oFld==null){continue}
oFld.readonly=true;
}

That worked for locking thank you!!!!

If I wanted to put a button to unlock the fields, to make changes - what would I change?

Thank you.

Check the Javascript console for errors. getFieldNames is not a function of Acrobat.
