Looping through a choice list

[#1]

I have a table called "Project Codes" which is connected to my change form as a choice list.
Project codes have a number and a company name ... what I would like to do is prune
all project codes that do not belong to a certain company after the company field has been
filled.

What I'm not sure about is how to loop through a choice list ... any pointers? 🙂

function onChange(control, oldValue, newValue, isLoading) {
 var requester = g_form.getReference('requested_by');
 if (requester.company) {
       var temp_pc_list = g_form.getReference('u_project_code');
       g_form.getControl('u_project_code').options.length = 0;
       
       // loop through temp_pc_list and add matching companies to u_project_code
       // while (not end of list(temp_pc_list)) {
       //      if   (list.element.company == requester.company) {
       //           g_form.addOption('u_project_code', '0', list.element);
       //       }
       //}
 }else{
      /*No Company ...  We don't do anything */
 }

}

Here's the loop:

var options = g_form.getControl('field_name').options;
for (i=0; i<options.length; i++) {
alert(options<i>.value);
}
