QUESTION
I am trying to generate a list of inputs from data and have they work as controlled inputs to capture their data. The text inputs seems to be getting captured well, but the file input onchange event get the error, "TypeError: _this2.handleFileInputChange is not a function". If I take it out of the arrow function, I do not get an error, but the callback still doesn't work. What do you wizards think?
---------- EDIT --------------
Implemented the suggestion to define the function as arrow function, which was fine, but the file input still does not seem to fire an on change event like the other fields. I'm beginning to think this is a limitation of the component.
Any other ideas? Thank you!

Answered 2021-May-05 at 02:10The this
of the class component isn't bound to the handleFileInputchange
callback handler.
You should bind this
to handleFileInputchange
in the constructor
or declare it as an arrow function.
QUESTION
I made a post earlier today asking how I could display an array on a page, and got some good pointers that helped in debugging, and brought me a step closer. However I need more pointers. Right now I am not even getting any errors, but still wont show the content of the array even though I can view it in the console. Here is my code:

QUESTION
Can you help with this issue - I am unable to see a log in the console. I was trying to log/view the data in the console with the codes below, but when i run it nothing shows. I think I have it correctly, but I might be wrong. Can you help?
...ANSWER
Answered 2021-Mar-28 at 22:07There's a lot of possibilities here since you're not providing the full code and we can't even debug this. So I'll just mention a couple of suggestions:
this.setState = ({newsPost: data})
should bethis.setState({newsPost: data})
.- Make sure that the API returns a proper answer.
- Make sure
process.env.REACT_APP_NEWS_ARTICLE_API
is returning the correct value as well. - Place a
console.log()
outside/before the axios promise, make sure thegetNews
method is being called.
