Cascading dropdown

[Mohammed Rayees Afroz]

Trying to implement cascading dropdowns.

But it goes in infinite ajax call loop when the first dropdown value is changed.

Any ideas?

I have the same problem!

I've found the only solution - handling onclick event instead of onchange but I still have 1 extra server call when user clicks on the first dropdown to select needed item.

I've found the solution: you have to attach the handler AFTER applying the model.

The code should look like following:

@ko.Apply(Model)

<script>
    $("#yourFirstList").change(function () { updateSecondList(); });
</script>

For me it works OK, no extra calls, no loops etc.
