Answer 1

You need to select jQuery in the dropdown on the left and you have a syntax error because the $(document).ready should end with }); not )}; Check this link.

Answer 2

You can select dropdown option value by name

jQuery("#option_id").find("option:contains('Monday')").each(function()
{
 if( jQuery(this).text() == 'Monday' )
 {
  jQuery(this).attr("selected","selected");
  }
});

UPDATED ANSWER:

Old answer, correct method nowadays is to use jQuery's .prop(). IE, element.prop("selected", true)

OLD ANSWER:

Use this instead:

$("#routetype option[value='quietest']").attr("selected", "selected");
