Function question

Function question

I have the following code which works fine:

var blackshFunction= function() {
      var j=0;
      for(var i=2;i<9;i++) {
         $("#altviews a").eq(j).attr("href","/v/vspfiles/photos/SMART-HOLSTER-" + i + ".jpg");
          $("#altviews a img").eq(j).attr("src","/v/vspfiles/photos/SMART-HOLSTER-" + i + "S.jpg");
         j=parseInt(j)+1;
      }
      $("#altviews a").eq(6).show();
      $("#altviews a img").eq(6).show();
}
var brownshFunction= function() {
      var j=0;
      for(var i=9;i<15;i++) {
         $("#altviews a").eq(j).attr("href","/v/vspfiles/photos/shbrown/SMART-HOLSTER-" + i + ".jpg");
         $("#altviews a img").eq(j).attr("src","/v/vspfiles/photos/shbrown/SMART-HOLSTER-" + i + "S.jpg");
         j=parseInt(j)+1;
      }
      $("#altviews a").eq(j).hide();
      $("#altviews a img").eq(j).hide();
}
$(document).ready(function() {
   $('#options_table a:eq(0)').click(blackshFunction);
   $('#options_table a:eq(1)').click(brownshFunction);
});

But I also want to do this, and I don't know how to call the same functions here without an event.

$("#options_table select").change(function() {
      var color = $("#options_table select option:selected").text();
      if (color='black') {
          run blackshFunction code...
      } else{
         run brownshFunction code...
      }
   });
