ReferenceError: event is not defined

Will County Attractions 

I have an app that works as it should in Chrome and IE. In FireFox it doesn't.

The error in the console is pointing to a specific line (line 2:15 here) of the html:

        attTypeSelect.addEventListener("change", function () {
          var type = event.target.value;
          setattractionsDefinitionExpression(type);
        });‍‍‍‍

Here's what is (or isn't) happening:

When you choose a Type from the dropdown menu it will not populate on the map.

Jared,

  I always use dojo/on for this:

        // set a new definitionExpression on the attractions layer
        on(attTypeSelect, "change", function (event) {
          var type = event.target.value;
          setattractionsDefinitionExpression(type);
        });‍‍‍‍‍

I tested in FireFox and it works fine.

Jared Pilbeam the code that Robert provided is fine, but if you don't want to use the dojo/on (which we have been removing from our samples to reduce dependencies), you could do a similar thing by just passing the event in the unnamed function. This also works fine across browsers, including Firefox. What is surprising is that Chrome and IE were smart enough to determine what the value of event was supposed to be.
