what javascript will loop through an array or evaluate a list for the following error checking javascript enbedded within a ColdFusion 9 form?

I have data returned from a query that outputs in an array named 'uarray' and a list named 'ulist'.

I have not succeeded in altering the following script to prompt the user with an error for the array or the list. It only works with a hard coded example that follows.

      if (document.updateForm.mtf_uic_id.value == 'N00160') {
              alert('Please enter a New UIC for this Associated MTF UIC.\n(An Associated MTF UIC must be unique.)');
             document.updateForm.mtf_uic_id.style.backgroundColor='yellow';
             document.updateForm.mtf_uic_id.focus();
             errorfound = true;
      }

The complete function follows:

function submitForm(){
            clearErrors();
            // alert("Submit Form was clicked");
            
      var errorfound = false;
            
      var uic = document.updateForm.mtf_uic_id.value
      var uic1 = uic.charAt(0)      

      if (document.updateForm.mtf_uic_id.value == 'N00160') {
              alert('Please enter a New UIC for this Associated MTF UIC.\n(An Associated MTF UIC must be unique.)');
             document.updateForm.mtf_uic_id.style.backgroundColor='yellow';
             document.updateForm.mtf_uic_id.focus();
             errorfound = true;
      }

      if(errorfound == false) {
      else {
            return false;
            }
      }

Thanks very much,
Mark
