Question

I think it’s fairly clear what I want to do here:

var viewnames = {};
viewnames['region-a'] = "Region A";
viewnames['region-b'] = "Region B, partial";
viewnames['region-c'] = "Region C";

function loadView(view_name) {
    alert('view_name: ' + view_name);
    alert('viewname: ' + viewnames.view_name);
    document.getElementById("viewtitle").innerText = view_name;
}

But if I call this with view_name as region-a the alert says viewnames.view_name is undefined. What is the problem?

You must use viewnames[view_name] inside your function loadView
