That won't work. Try this test:
alert( "" + null ); // "null" - but we wanted ""
This would work:
$('#verMailDate').attr( "value",data.verMailDate == null ? "" :
data.verMailDate );
Or if it's OK to treat 0 the same as null, this simpler code would work:
$('#verMailDate').attr( "value",data.verMailDate || "" );
