I have created a simple login function where once the user log in, he is redirect to another page. Then I wanted to change the login form with a form dialog. And the problem is here. The login dialog works, but when I enter the username and password, I'm not send to another page but to the same login page :/.
Here is the code:
Login.jsx:
...ANSWER
Answered 2020-Nov-02 at 21:09I notice that your Login
component is a class, while the child FormDialog
component is a function component using Hooks. There's nothing wrong with that, in itself - particularly if you started with an application using all class components and are slowly converting your components. But I detect some confusion here, because your function component seems to assume it's a class, in a sense. When you need to do things a bit differently.
Specifically, you reference this.login
in your function component - but this is meaningless. login
is passed in as a prop. In a class component, you would reference it as this.props.login
. This doesn't work in a function component - but this.login
isn't the substitute. Indeed this
will tend to be undefined
so this would even give an error. Even if not, it's not correct.
All you need to do is to make use of the argument to your function component - this is where the props
object "lives" in a function component. You happen to ignore it by not using any arguments - but you don't have to do this.
So in short, what you need to do is:
replace
export default function FormDialog()
withexport default function FormDialog(props)
replace
this.login
withprops.login
repeat 2) for all other props which you have referenced using
this

QUESTION
This is one of the first times I am actually using React Hooks properly in a project so bear with me if I am not quite there.
In the component below, my aim is to display the on load and when the scrolling div (not the window) scrolls I want to hide after it scrolls X amount of pixels.
My thought process is to create a useRef object on the scrolling
I have created a Codesandbox below to try and demonstrate what I am trying to do. As you can see in the demo the node.addEventListener('click')
is working fine, however when I try and call the node.addEventListener('scroll')
it is not firing.
I'm not sure if I taking the wrong approach or not, any help will greatly be appreciated. In the codesandbox demo it is the react image that I trying to hide on scroll, not the

...ANSWER
Answered 2019-Mar-26 at 14:49In your example, the scroll is not triggered on the scrolling-element
but on the scrolling-container
so that's where you want to put your ref : https://codesandbox.io/s/ko4vm93moo :)
But as Throlle said, you could also use the onScroll prop !

QUESTION
Basically I've got a div at the top of my website which has the logo, initially the logo has a height and the div is going to size to the logo height (200px in the pen).
What I want to do is, make the logo smaller while I scroll down, or bigger while I scroll up, basically the scrollY value needs to be somehow linked to the image heigh (until I get to a point scroling down where I don't want to keep shrinking the logo).
I've tried setting the height css property with a state and updating it with an eventlistener that updates the state every time it detects scrolling.
This didn't worked (but maybe I coded that wrong).
Any ideas how could I do this?
Here's the JS:
