Save Warning process

Question

I wanted to give the users a warning message if they tried to exit a page without saving. I had implemented the 'WarnSave' procedure I saw in the forum threads. It works great except for date fields. If the user hits the 'Calendar' image that show next to a date, the warning alert pops up. Any suggestions?
<script type="text/javascript">
function WarnSave()
var formChanged=isFormChanged();
if (!g_saving && formChanged) return g_errmsg;
function isFormChanged() {
var rtnVal = false;
var frm = document.wwv_flow;
var ele = frm.elements;
for ( i=0; i < ele.length; i++ ) {
if ( ele.type.length > 0 ) {
if ( isElementChanged( ele, i ) ) {
rtnVal = true;
break;
return rtnVal;
function isElementChanged( ele, i ) {
var isEleChanged = false;
switch ( ele[i].type ) {
case "text" :
if ( ele[i].value != ele[i].defaultValue && ele[i].style.backgroundColor == "yellow" ) return true;
break;
var g_saving = false;
var g_errmsg="There are unsaved changes on this page.";
g_errmsg += "\n- To save your changes, click the Cancel button, and then click on the Submit button.";
g_errmsg += "\n- To disregard your changes, click on the OK button.";
function doSave()
g_saving=true;
doSubmit('SAVE');
function doCreate()
g_saving=true;
doSubmit('CREATE');
function doCancel()
g_saving=false;
doSubmit('CANCEL');
</script>

Bob,
Great, let me know when it's up. Also, I'll need some credentials. As for jQuery, I too have heard that it will be included with a future release. I don't want to speculate, however, as to when. But adding jQuery is such an easy thing to do I wouldn't wait to make this change. In fact, I was planning to look at your example and make a newer version with jQuery code. The reason being that there are many different item types in an ApEx application and I don't know if that code is the best way to go. It should be fun to rewrite in jQuery.
