I have multiple javascripts that I call that are all "onclick" events. For example, I have a Drive time script and a Routing script. Both are "onclick" events. I don't know how to give the choice of which one to use in the application. Do I make a submit button and somehow link it to that event? Or a drop down menu with a link? What is that best way to distinguish which script is going to be called when you click on a map? Thanks.
