Accordion as nested menu

Question

I have the following setup:
<div id="regionMainMenu"
spry:region="dsMenu">
<div id="Accordion1"
class="Accordion"
tabindex="0">
<div id="regionMenuItems"
spry:repeat="dsMenu"
class="AccordionPanel">
<div
class="AccordionPanelTab">{Text}</div>
<div id="menuItem"
class="AccordionPanelContent">
<div
id="regionSubMenu">{Text}</div>
</div>
</div>
</div>
<script
type="text/javascript">
<!--
var ac1 = new
Spry.Widget.Accordion("Accordion1",{useFixedPanelHeights:false,
defaultPanel:0});
//-->
</script>
</div>
Because spry-region does not support nested regions. I loaded
the complete menu.xml in another dataset. and use onDataChange
observer to populate the AccordionContent with the current MenuID..
See below:
var dsMenuData = new
Spry.Data.XMLDataSet("data/menu.xml",
"Menus/Menu");
dsMenuData.addObserver({onDataChanged:function(ds,
data){return dsMenuData_DataChanged(ds, data, 1)}});
var dsMenuData_DataChanged = function(dataSet, data,
datasetnumber)
Spry.$$("#regionSubMenu").forEach(function(div) {
ListSubmenus(div); });
function ListSubmenus(menu)
//GetSubMenus
if(menu && dsMenuData)
//dsMenuData.loadData();
var rows =
dsMenuData.getData();//.findRowsWithColumnValues({ParentID:
"'" + menu.innerHTML + "'"});
if(rows.length>0)
var subItems = "==";
var c = menu.innerHTML;
for (var i = 0; i < rows.length; i++)
{ var p = rows
["ParentID"];
if(p && c && p == c)
subItems += " • " +
rows["Text"] +
" " + c + ":[" + p
+ "]<br>";
menu.innerHTML = subItems;
else
menu.innerHTML = "none";
else
menu.innerHTML = "---";
The issue I am having is in the bold line "var c =
menu.innerHTML;" I can assign a number like 1 or 2 to c..
and it finds the menus. I can even compare
"parentID" with a string and it finds them. But
whenever I leave it has is and pass the menu.innerHTML it doesn't
work. Is there something programatically incorrect with doing this?
I even print out menu.innerHTML on the same line and it returns the
value I need. I strip spaces convert to string number, doesn't
matter. What am I doing wrong?
Any one please help thanks.

Answer 1

1. Yes. What third table would you need?
2. No & No.
You shouldn't be able to delete a category if it has products as children.
You should have tables..
Category
CategoryID (INT) - Primary Key, Auto number
CategoryName
etc
Products
ProductID (INT) - Primary Key, Auto number
ProductName
CategoryID (INT) - Foreign Key to Category
etc
If you change something in Category, NOTHING changes in Products.
