Question

 var makeModelYearSelect = document.getElementById("<%= MakeModelYearFilterLB.ClientID %>").control;
 var selectedMakeModelYearItems = makeModelYearSelect.get_checkedItems();
 var selectedMakeModelYearItemIds = [];


 for (var index = 0; index < selectedMakeModelYearItems.length; index++) {
   selectedMakeModelYearItemIds.push(selectedMakeModelYearItem[index].get_value(index));
 }

Why is this firing back an error of Microsoft JScript runtime error: 'selectedMakeModelYearItem' is undefined?

Mootools won’t let me use a simple for…in for iterations.

I’ve looked at it 6 ways to Sunday so what the heck am I missing?

Answer 1

Because selectedMakeModelYearItem is undefined.

selectedMakeModelYearItems isn’t, though.
