Sometimes, we want to stop a YouTube video with JavaScript.
In this article, we’ll look at how to stop a YouTube video with JavaScript.
To stop a YouTube video with JavaScript, we call the stopVideo method.
For instance, we write
player.stopVideo();
to call the YouTube player‘s stopVideo method to stop the video.
To stop a YouTube video with JavaScript, we call the stopVideo method.
Sometimes, we want to convert month name to month number in JavaScript.
In this article, we’ll look at how to convert month name to month number in JavaScript.
To convert month name to month number in JavaScript, we use the date toLocaleDateString method.
For instance, we write
const month = new Date().toLocaleDateString(`en`, { month: `2-digit` });
to call toLocaleDateString with the locale string and an object with the month property.
We set it to '2-digit' to return a 2 digit month.
To convert month name to month number in JavaScript, we use the date toLocaleDateString method.
Sometimes, we want to fix ReferenceError: document is not defined with Next.js and JavaScript.
In this article, we’ll look at how to fix ReferenceError: document is not defined with Next.js and JavaScript.
To fix ReferenceError: document is not defined with Next.js and JavaScript, we check if document is defined.
For instance, we write
if (typeof document === "undefined") {
// ...
} else {
// ...
}
in our component to check if document is undefined with typeof document === "undefined".
If it’s not defined, then we render items on server side.
Otherwise, we render client side components.
Sometimes, we want to implement media queries with React.
In this article, we’ll look at how to implement media queries with React.
To implement media queries with React, we create our own hook.
For instance, we write
const useMediaQuery = (query) => {
const [matches, setMatches] = useState(false);
useEffect(() => {
const media = window.matchMedia(query);
if (media.matches !== matches) {
setMatches(media.matches);
}
const listener = () => setMatches(media.matches);
window.addEventListener("resize", listener);
return () => window.removeEventListener("resize", listener);
}, [matches, query]);
return matches;
};
export default useMediaQuery;
to create the useMediaQuery hook.
In it we check if the media query matches the screen size with window.matchMedia.
Then we call setMatches if media.matches is different from matches.
We then call addEventListener to listen to the resize event with listener.
And we call removeEventListener if matches or query changes.
Then we call useMediaQuery in our component to see if our screen matches the media query string.
To implement media queries with React, we create our own hook.
Sometimes, we want to detect the onload event of a window opened with window.open with JavaScript.
In this article, we’ll look at how to detect the onload event of a window opened with window.open with JavaScript.
To detect the onload event of a window opened with window.open with JavaScript, we set the popup’s onload method.
For instance, we write
const popup = window.open(location.href, "snapDown");
popup.onload = () => {
alert("message one");
};
to call window.open to open a popup window that opens the location.href URL.
Then we set its onload property to a function that’s run when the popup window finishes loading.
To detect the onload event of a window opened with window.open with JavaScript, we set the popup’s onload method.
