Javascript Array addEventListener

Question

Interactive map with buttons in the shape of states, each button has the state abbreviation as an id, when a button/state is clicked I would like to fire the function \"stat

Answer 1

Because when the handler runs, it looks up the value of i, which is wherever it was after the loop finished.

You need to scope the i variable in a function:

function listenerForI( i ) {
    document.getElementById(stateList[i]).addEventListener('mousedown', function() {stateSelect(stateList[i])}, false);
}
for (var i = 0; i < stateList.length; i++) {
    listenerForI( i );
}

Now the i referenced by the handler will be the parameter to the listenerForI function that was invoked. As such, that i will reference the value that was passed in from the for loop.
