QUESTION
I want to create second event from a button that i have created from the first event. i don't know how to grab the button with an id btn_event_2
and save it into variable like i just did on the first event, so i cant create an event listener on the second button. Any suggest, thanks.

function.

I am new with reactjs.
This is what I am trying

Answered 2018-Mar-28 at 20:30First of all,you shouldn't call your this.getStarWars() function inside the constructor, it is a very bad practice and could cause you troubles, http calls in React component should be generally called from the componentDidMount function.
However the issue in this case is another one,you haven't given an initial value to this.state.names, so when the component tries to do the initial render it fails because the names are undefined since the initial render appens before the http call is resolved
You code should be fixed like this:
QUESTION
So I am creating a type of event handler and I am in the process of writing an "Event Listener Wrapper", if you will.
The basic idea is this: When you want to subscribe to an event, you create a function that should be called when the event fires. <-- already have that done (kinda, I'll explain)
You put this listener function into a wrapper to pass the function onto the dispatcher.
The dispatcher gets an event, finds the wrapper for you listener, and calls the underlying function with the parameter values set by the event.
I already have something working so long as the listeners all only accept one argument of my EventBase
class. Then I have to type cast that into the proper event that the listener is passed.
What I want instead is for my listener functions to have "any" type of arguments, and store the function in a way that lets me call it with any arguments I want depending on the event fired. Each listener function would only ever receive one type of event, or the event it's self. This would allow me to not have to type cast each event in every listener, but instead the correct event would be passed.
I found a bit of code for this wrapper that is almost perfect, with a few minor issues that I can't seem to fix. I'll explain below.
