Script Categories

Forms >>> Items Popup List.

If you have several items for the user to pick from, you may notice that your page can quickly becomes cluttered. This script helps solve that problem by opening a new window when the user wants to add items to the list. The new window displays the items and passes the selected item information back to the list in the main window.

This script also requires the MODIFY.HTML file in the current directory.

Add the below code to the <body> section of your page:

<script language="javascript" type="text/javascript">

<!-- Begin
function small_window(myurl) {
var newWindow;
var props = 'scrollBars=yes,resizable=yes,toolbar=no,menubar=no,location=no,directories=no,width=300,height=250';
newWindow =, "NewWin", props);
// Adds the list of selected items selected in the child
// window to its list. It is called by child window to do so.
function addToParentList(sourceList) {
destinationList = window.document.popup.parentList;
for(var count = destinationList.options.length - 1; count >= 0; count--) {
destinationList.options[count] = null;
for(var i = 0; i < sourceList.options.length; i++) {
if (sourceList.options[i] != null)
destinationList.options[i] = new Option(sourceList.options[i].text, sourceList.options[i].value );
// Marks all the items as selected for the submit button.
function selectList(sourceList) {
sourceList = window.document.popup.parentList;
for(var i = 0; i < sourceList.options.length; i++) {
if (sourceList.options[i] != null)
sourceList.options[i].selected = true;
return true;

// Deletes the selected items of supplied list.
function deleteSelectedItemsFromList(sourceList) {
var maxCnt = sourceList.options.length;
for(var i = maxCnt - 1; i >= 0; i--) {
if ((sourceList.options[i] != null) && (sourceList.options[i].selected == true)) {
sourceList.options[i] = null;
//  End -->
