React input onChange won't fire

Question

I currently have this simple react app and I cannot get these onchange events to fire for the life of me.

var BlogForm = React.createClass({
getInitialState:         


        

Answer 1

when you use :

onChange={this.changeTitle (this)}

react will call mentioned function automatically. you need to call the function like this:

onChange={this.changeTitle}

and also change your mentioned function to arrow function, otherwise you cant use "this" keyword in your function. in none arrow function "this" keyword is not object of your function so you cant access to your variables. if you need to pass arguments to your function you should use other methods like bind()
