unmute react-player when fullscreen is toggled from outer component - reactjs

I have a VideoItem- and a Player-component
In VideoList a button is clicked and is going to fullscreen mode (is working as expected)
I will unmute player when fullscreen is clicked.
How can I pass down a "mute" change from VideoList to Player? In my Player I also have a "Unmute" button (which is also working as expected:
This is what I have so far
VideoItem.jsx
import React, { useRef, useState, useEffect } from "react"
import { findDOMNode } from "react-dom"
import screenfull from "screenfull"
import VideoPlayer from "./VideoPlayer"
const VideoList = (videos) => {
const ref = useRef()
const toggleFullScreen = () => {
screenfull.request(findDOMNode(ref.current))
}
const unMute = () => {
console.log("Should pass Mute state to player", muted)
}
return (
<>
<VideoPlayer
ref={ref}
mute={muted}
videoURL={videoUrl}
/>
<a
href="#"
onClick={e => {
e.preventDefault()
unMute()
toggleFullScreen()
}}
>
Show Fullscreen
</a>
)
}
Player.jsx
import React, { forwardRef, useState, useEffect } from "react"
import ReactPlayer from "react-player"
const VideoPlayer = forwardRef((props, ref, mute) => {
let [muteState, setMuteState] = useState(true)
return (
<>
<i className={`fal fa-volume-${muteState ? "up" : "mute"}`}
onClick={() => {
setMuteState(!muteState)
}}
/>
<ReactPlayer
ref={ref}
muted={muteState}
loop={true}
playing={true}
url={props.videoURL}
/>
</>
)
}
Thank you!

When you attempt to set the state from the parent this usually is an indicator that you should move the state up and make the child controlled by the parent:
const VideoList = (videos) => {
const player = useRef();
const [muted, setMuted] = useState(true);
const [fullscreen, setFullscreen] = useState(false);
const handleToggleMute = () => setMuted(current => !current);
const handleFullscreen = event => {
event.preventDefault();
setMuted(false);
setFullscreen(true);
};
return (
<>
<VideoPlayer
ref={ref}
muted={muted}
fullscreen={fullscreen}
videoURL={videoUrl}
onToggleMute={handleToggleMute}
/>
<a href="#" onClick={handleFullscreen}>Show Fullscreen</a>
)
}
Also I would use useEffect together with another state fullscreen to avoid having to forward a ref of the video player.
const VideoPlayer = ({videoURL, muted, fullscreen, onToggleMute}) => {
const playerRef = useRef();
useEffect(() => {
if (fullscreen) {
const videoElem = playerRef.current.getInternalPlayer();
screenfull.request(videoElem);
}
}, [fullscreen]);
return (
<>
<i
className={`fal fa-volume-${muted ? "up" : "mute"}`}
onClick={onToggleMute}
/>
<ReactPlayer
ref={playerRef}
muted={muted}
loop={true}
playing={true}
url={videoURL}
/>
</>
)
}

React Outside Hook not reacting to outside Click

I am finishing up a project where I want to use a small dropdown menu when I click on my settings icon. The problem is that for some reason it is not recognized when I click outside of that dropdown menu. I used a hook that worked in the same project with a different dropdown menu, but now it doesn't. Maybe because it is in a modal? I really don't know.
Here is the Repo of this Project: https://github.com/Clytax/fem-kanban
The Hook (I modified it a bit by excluding the elipsis icon so it doesnt reopen when Click on it to close it.)
import React from "react";
export const useOutsideClick = (callback, exclude) => {
const ref = React.useRef();
React.useEffect(() => {
const handleClick = (e) => {
if (
ref.current &&
!ref.current.contains(e.target) &&
!exclude.current.contains(e.target)
) {
callback();
}
};
document.addEventListener("click", handleClick);
return () => {
document.removeEventListener("click", handleClick);
};
}, [callback, exclude]);
return ref;
};
The Modal:
import React, { useRef, useState, useEffect } from "react";
import "./taskModal.scss";
import { ReactComponent as Elipsis } from "../../../assets/Icons/icon-vertical-ellipsis.svg";
import { ReactComponent as Close } from "../../../assets/Icons/icon-chevron-up.svg";

import { useSelector, useDispatch } from "react-redux";
import modalSlice, {
closeViewTaskModal,

closeAllModals,
openDeleteTaskModal,
} from "../../../features/global/modalSlice";
import Backdrop from "../Backdrop/Backdrop";
import Subtask from "../../Task/Subtask";
import "../../Extra/DropdownSettings.scss";
import { useOutsideClick } from "../../../hooks/useOutsideClick";
import { motion } from "framer-motion";
import DropdownStatus from "../../Extra/DropdownStatus";
import DropdownSettings from "../../Extra/DropdownSettings";
import DropdownSettingsTask from "../../Extra/DropdownSettingsTask";
const ViewTaskModal = ({ handleClose }) => {
const [openSettings, setOpenSettings] = useState(false);
const dispatch = useDispatch();
const task = useSelector((state) => state.modal.viewTaskModal.task);
const handleCloseSettings = () => {
console.log("hi");
setOpenSettings(false);
};
const modal = useSelector((state) => state.modal);
const viewTaskModal = useSelector((state) => state.modal.viewTaskModal);
const elipsisRef = useRef(null);
const wrapperRef = useOutsideClick(handleCloseSettings, elipsisRef);
const getFinishedSubTasks = () => {
let finishedSubTasks = 0;
task.subTasks.forEach((subtask) => {
if (subtask.isDone) {
finishedSubTasks++;
}
});
return finishedSubTasks;
};
const closeModal = () => {
dispatch(closeViewTaskModal());
};
return (

Trying to get Material ui dialog into contextualised modal

I have a modal component which I have put into context.
If I return html , some divs etc, then no problem, but
ideally I want to do this with the material-ui dialog.
But if I put in materail-ui dialog, as below,
then nothing is displayed.
The component:
import React, { useCallback, useEffect, useState } from 'react'
import {Dialog, DialogActions, DialogContent, DialogContentText, DialogTitle} from "#material-ui/core";
import {useTranslation} from "react-i18next";
import {errorStyles} from "../errorStyle";
// Create a React context
const ModalContext = React.createContext(null);
//Declare the modal component
const Modal = ({ modal, unSetModal, errorClasses = errorStyles(),
title, subtitle, children, }) => {
useEffect(() => {
const bind = e => {
if (e.keyCode !== 27) {
return
}
if (document.activeElement && ['INPUT', 'SELECT'].includes(document.activeElement.tagName)) {
return
}
unSetModal()
}
document.addEventListener('keyup', bind)
return () => document.removeEventListener('keyup', bind)
}, [modal, unSetModal])
const { t } = useTranslation()
return (
<>
<Dialog
className={errorClasses.modal}
fullWidth
maxWidth='md'
aria-labelledby='max-width-dialog-title'
>
<DialogTitle id='max-width-dialog-title'
className={errorClasses.header}>{title}</DialogTitle>
<DialogContent>
<DialogContentText>{subtitle}</DialogContentText>
</DialogContent>
<DialogActions>
<button className={errorClasses.cancelButton}
onClick={unSetModal}>{t("Close")}</button>
</DialogActions>
</Dialog>
</>
)
}
const ModalProvider = props => {
const [modal, setModal] = useState()
const unSetModal = useCallback(() => {
setModal('')
}, [setModal])
return (
<ModalContext.Provider value={{ unSetModal, setModal }} {...props} >
{props.children}
{modal && <Modal modal={modal} unSetModal={unSetModal} />}
</ModalContext.Provider>
)
}
// useModal: shows and hides the Modal
const useModal = () => {
const context = React.useContext(ModalContext)
if (context === undefined) {
throw new Error('useModal must be used within a UserProvider')
}
return context
}
export { ModalProvider, useModal }
And in another component (an edit form)
import { useModal, ModalProvider } from '../context/modal-context'
.....
export function DeviceModal (props) {
const { setModal } = useModal()
...
some other markup
<div style={{ position: 'sticky', bottom:'0', width:'100%', height:'40px', paddingTop:'5px'}}>
<Grid container direction="row-reverse" item xs={12} alignItems="right">
<button className={classes.cancelButton}
onClick={() => { setModal(<></>)}} >
{'Cancel'}
</button>
</Grid>
</div>
Hope someone can help
Thanks
Answer:
By adding the following to the dialogprops, it is resolved.
open={true}
backdropComponent={Backdrop}
and also, getting it to display values from the parent.
const ModalProvider = props => {
const [modal, setModal] = useState();
const [title, setTitle] = useState();
const [errMsg, setErrMsg] = useState();
const unSetModal = useCallback(() => {
setModal('')
}, [setModal])
// Provide the Modals functions and state variables to the consuming parent component
return (
<ModalContext.Provider value={{ unSetModal, setModal, setTitle, setErrMsg }} {...props} >
{props.children}
{modal && <Modal modal={modal} unSetModal={unSetModal} title={title} errMsg={errMsg} />}
</ModalContext.Provider>
)}
In the parent use setTitle("yada yada") setErrMsg('more yerra yada");

Destructed props sent to child component returning undefined

I'm a bit lost here. I've done this a bunch of time and have never had this issue before. I'm passing a boolean state to a modal component. I followed the code from the parent and it is set properly but as soon as it gets to the modal it returns as undefined.
Here is the parent:
import React, { useEffect, Fragment, useState } from 'react'
import './styles.css'
import LandingPageModal from './LandingPageModal'
import { testImages } from './testData'
const LandingPage = () => {
const [images, setImages] = useState([])
const [renderImages, setRenderImages] = useState(false)
const [showModal, setShowModal] = useState(false)
const [isLoaded, setIsLoaded] = useState(false)
useEffect(() => {
setImages(testImages)
setShowModal(true)
setIsLoaded(true)
}, [])
useEffect(() => {
if (images && images.length > 0) {
setRenderImages(true)
}
}, [images])
const FeaturedUsers = () => {
return (
renderImages ?
<Fragment>
<div className='grid'>
{images.map((image) => (
<img src={`/images/${image.src}`} alt={image.caption} />
))}
</div>
</Fragment> : ''
)
}
return(
isLoaded ?
<Fragment>
<FeaturedUsers />
<LandingPageModal show={showModal} />
</Fragment> : ''
)
}
export default LandingPage
and here is the modal:
import React, { useState, useEffect } from 'react'
import ReactModal from 'react-modal'
import './styles.css'
const LandingPageModal = ({ showModal }) => {
const [isModalOpen, setIsModalOpen] = useState(showModal)
console.log('Is Show: ' + showModal)
return (
<ReactModal
isOpen={isModalOpen}
>
<div className='main-wrapper'>
<div className='text'>
<p>
<strong>Welcome</strong>
<br />
<br />
Please sign in or sign up
</p>
</div>
</div>
</ReactModal>
)
}
export default LandingPageModal
In the LandingPage component, you accidentally renamed showModal to show.

Reactjs useState not changing boolean state and not rendering child component on click

I am trying to display the SingleLineText component below that has one input field when a click occurs in the parent component called TextInput. However, after a click, the state is not changed by useState and as a result the child component named SingleLineText is not displayed.
TextInput component is pasted below right after SingleLineText component.
SingleLineText component:
import React from "react";
const SingleLineText = () => {
return(
<form>
<input />
</form>
)
}
export default SingleLineText;
TextInput the Parent component for SingleLineText component:
import React, {useState, useEffect} from "react";
import SingleLineText from "./SingleLineText"
const TextInput = (props) => {
const [showSingleText, setShowSingleText] = useState(false);
useEffect( () => {
}, [showSingleText])
const handleFieldDisplay = (event) => {
if (event.target.value == "Single line text") {
cancel();
setShowSingleText(showSingleText => !showSingleText);
//setShowSingleText(showSingleText => true);
}
}
const cancel = () => {
props.setShowInput(!props.showInput);
}
return (
<>
<div className="dropdown">
<ul key={props.parentIndex}>
{
props.fieldType.map( (val, idx) => {
return(
<option key={idx} value={val} className="dropdown-item" onClick={handleFieldDisplay}> {val} </option>
)
})
}
</ul>
</div>
{showSingleText && <SingleLineText />}
</>
)
}
export default TextInput;
Topmost or grand parent component:
import React, { useState, useEffect, useRef } from "react"
import PropTypes from "prop-types"
import TextInput from "components/pod_table/fields/inputs/TextInput";
const DynamicFields = (props) => {
const fieldType = ['Checkbox', 'Dropdown', 'boolean', 'Single line text'];
const [showDynamicField, setShowDynamicField ] = useState(false);
const[showInput, setShowInput] = useState(false);
useEffect(() => {}, [showDynamicField, showInput]);
const handleShowDynamicField = (event) => {
setShowDynamicField(!showDynamicField);
}
const handleSubDisplay = (event) => {
if (event.target.value == "customise field type") {
setShowDynamicField(!showDynamicField);
setShowInput(!showInput);
}
}
return (
<React.Fragment>
<div>
<i className="bi bi-chevron-compact-down" onClick={handleShowDynamicField}></i>
{ showDynamicField &&
(<div className="dropdown">
<ul key={props.parentIndex}>
{
optionsHash.map( (val, idx) => {
return(
<option key={idx} value={val} className="dropdown-item" onClick={handleSubDisplay}> {val} </option>
)
})
}
</ul>
</div>) }
{showInput && <TextInput fieldType={fieldType} setShowInput={setShowInput} showInput={showInput} /> }
</div>
</React.Fragment>
)
}
The problem is that in the handleFieldDisplayFunction you are calling the cancel function which changes the parent state showInput and hence unmounts the TextInput component itself, so the showSingleText state changes inside TextInput component doesn't have any effect.
Design your code in a way that you are not required to unmount TextInput when you click on an option within it
const handleFieldDisplay = (event) => {
if (event.target.value == "Single line text") {
setShowSingleText(showSingleText => !showSingleText);
}
}

document.querySelector() always return null when clicking on React Router Link the first time but will return correctly after

I'm stucking on a problem with React-Router and querySelector.
I have a Navbar component which contains all the CustomLink components for navigation and a line animation which listens to those components and displays animation according to the current active component.
// Navbar.tsx
import React, { useCallback, useEffect, useState, useRef } from "react";
import { Link, useLocation } from "react-router-dom";
import CustomLink from "./Link";
const Layout: React.FC = ({ children }) => {
const location = useLocation();
const navbarRef = useRef<HTMLDivElement>(null);
const [pos, setPos] = useState({ left: 0, width: 0 });
const handleActiveLine = useCallback((): void => {
if (navbarRef && navbarRef.current) {
const activeNavbarLink = navbarRef.current.querySelector<HTMLElement>(
".tdp-navbar__item.active"
);
console.log(activeNavbarLink);
if (activeNavbarLink) {
setPos({
left: activeNavbarLink.offsetLeft,
width: activeNavbarLink.offsetWidth,
});
}
}
}, []);
useEffect(() => {
handleActiveLine();
}, [location]);
return (
<>
<div className="tdp-navbar-content shadow">
<div ref={navbarRef} className="tdp-navbar">
<div className="tdp-navbar__left">
<p>Todo+</p>
<CustomLink to="/">About</CustomLink>
<CustomLink to="/login">Login</CustomLink>
</div>
<div className="tdp-navbar__right">
<button className="tdp-button tdp-button--primary tdp-button--border">
<div className="tdp-button__content">
<Link to="/register">Register</Link>
</div>
</button>
<button className="tdp-button tdp-button--primary tdp-button--default">
<div className="tdp-button__content">
<Link to="/login">Login</Link>
</div>
</button>
</div>
<div
className="tdp-navbar__line"
style={{ left: pos.left, width: pos.width }}
/>
</div>
</div>
<main className="page">{children}</main>
</>
);
};
export default Layout;
// CustomLink.tsx
import React, { useEffect, useState } from "react";
import { useLocation, useHistory } from "react-router-dom";
interface Props {
to: string;
}
const CustomLink: React.FC<Props> = ({ to, children }) => {
const location = useLocation();
const history = useHistory();
const [active, setActive] = useState(false);
useEffect(() => {
if (location.pathname === to) {
setActive(true);
} else {
setActive(false);
}
}, [location, to]);
return (
// eslint-disable-next-line react/button-has-type
<button
className={`tdp-navbar__item ${active ? "active" : ""}`}
onClick={(): void => {
history.push(to);
}}
>
{children}
</button>
);
};
export default CustomLink;
But it doesn't work as I want. So I opened Chrome Devtool and debugged, I realized that when I clicked on a CustomLink first, the querySelector() from Navbar would return null. But if I clicked on the same CustomLink multiple times, it would return properly, like the screenshot below:
Error from Chrome Console
How can I get the correct return from querySelector() from the first time? Thank you!
It's because handleActiveLine will trigger before setActive(true) of CustomLink.tsx
Add a callback in CustomLink.tsx:
const CustomLink: React.FC<Props> = ({ onActive }) => {
useEffect(() => {
if (active) {
onActive();
}
}, [active]);
}
In Navbar.tsx:
const Layout: React.FC = ({ children }) => {
function handleOnActive() {
// do your query selector here
}
// add onActive={handleOnActive} to each CustomLink
return <CustomLink onActive={handleOnActive} />
}
