assign javascript array values to dropdowns and select elements

// i do this after the form is completed loaded so that the elements are adjusted as per the array obtained. Sample array would be  [Y,Y,N,N,N,N,N,1200, 1800] 
<script>
 
var hop = <%=pff.getHOPDetails()%>'
 
 
var rowsRequired = hop.split(","); // here i;m getting the array // 
//elements into javasscript array
 
alert (rowsRequired.length/9);
 
for ( i = 0 ; i < rowsRequired.length/9 ; i ++ ) {
alert ("Adding rows");
addRowForHoursOfOperation("hours");
 
setHoursofOperationDetails(rowsRequired); // need to finish this part
 
 
} 
</script>
 
 
 
 
function setHoursofOperationDetails(rowsRequired){
	var table = document.getElementById( 'hours' );
    var Rows  = table.rows;            // Rows in the table
    var DoW   = new Array( 7 );        // information for each Day of Week
 
	for ( var totalRows = 0 ; i <   rowsRequired.length / 9 ; i ++ )  {
		 var thisRow = Rows[ totalRows ];    
		for ( i = 0 ; i < rowsRequired.length ; i ++) {
		alert ("1");
		  // set day of the week values
		  for ( var j = 4; j < 11; j ++ ) {
  			alert ("2");
		  	if ( rowsRequired [i++] == 'Y' ){
		  	  			alert ("3");
		  		thisRow.cells[ j ].firstChild.checked = true;
	  		}else {
