How do I get link metadata when shared on social media?
This is a waiting page to redirect visitors to another site link when I type the page link
Then # the link that I want the visitor to go to, waiting for the counter, then clicking on the button, it will go to the other site after the # sign
When I share the link on any social networking site, it shows metadata for the waiting page
How do I get the metadata of the link that the visitor will go to?
They make a request to the link that you provide. You can see that when you use grabify (here you will see the request). Then you can parse the html to get the metadata. You should make the request from the bakend and store the result, so that you dont have to reuqest the information multiple times. Also it is unlikely that the request will be allowed cross domain. You can test it by using fetch for example to get the google homepage like this fetch("https://google.com/") however this will return a CORS policy: No 'Access-Control-Allow-Origin' error.

I am trying to get the input value as my result but after clicking on the button I am getting 'undefined' as the console result. Please help to understand the reason. Sharing the HTML and js code

You are using a class for multiple elements which is why undefined is shown. Among many ways, I will discuss two here, you have to either use indices with classes if using queryselector to get the correct element or use an ID to select the input element. Here I have used ID to get the input searchbox. See the following code:
const moviesearchEngine = () => {
let searchBox = document.querySelector('#searchBoxInput');
console.log(searchBox.value)
}

Your div <div class="searchBox"> also contain a class "searchBox" so it selected that.
Fixed: Add an input selector after class selector.
const moviesearchEngine=()=>{
let searchBox = document.querySelector('.searchBox input');
console.log(searchBox.value)
}

How to get piece of information from url given
Hi i have this html code:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link type="text/css" rel="stylesheet" href="/style.css"/>
<link rel="icon" href="">
<title>Submit</title>
</head>
<body>
<script>
function show_alert() {
alert("Animes score is: ");
}
</script>
<div class=střed>
<form>
<div id="one"><input style="width: 500px" type="text" name="url" value="Enter myanimelist URL" onfocus="if (this.value=='Enter myanimelist URL') this.value='';"/></div>
<div id="two"><input type="image" onclick="show_alert();" name="submit" src="/Button1.png" border="0" alt="Submit" />
</div>
</form>
</div>
</body>
</html>
Now i want to get from user's url (for example: https://myanimelist.net/anime/5114/Fullmetal_Alchemist__Brotherhood) the anime's score from page's html (this part: <span itemprop="ratingValue">9.26</span> - so in this case it would be 9.26) and show it in alert box (doesn't need to be alert box thought, just somehow show it to user). Thanks for any help.
Javascript - How to transform index chat into a chat window
Actually I have some chat and I want to put it inside a window, I found an example but Not loading the chat inside window.
My chat works perfectly with just the index. Check the images.
Old index.ejs code (just chat):
<html>

<script src="app.js"></script>

I see that example for it.
And the error is:
Synchronous XMLHttpRequest on the main thread is deprecated because of
its detrimental effects to the end user's experience. For more help,
check https://xhr.spec.whatwg.org/.
Uncaught TypeError: Cannot read property 'classList' of null

Uncaught TypeError: Cannot read property 'classList' of null
at displayPayload (eval at (jquery.min.js:2), :80:23)
Obs.: The old file index.ejs is the new chat.ejs to load the chat inside window if click the button.
I try see other post with same example but None of them are trying the same as me
In the case I put all .css style inside my css repository, and I added the scripts src inside the index. After it, works fine. I did not need chat.ejs and I inserted all the code in the index just with the .css inside my repository public/css/app.css

Add the meta-tags to the head on your HTML <meta property="og:url" content="http://www.nytimes.com/2015/02/19/arts/international/when-great-minds-dont-think-alike.html" /> <meta property="og:type" content="article" /> <meta property="og:title" content="When Great Minds Don’t Think Alike" /> <meta property="og:description" content="How much does culture influence creative thinking?" /> <meta property="og:image" content="http://static01.nyt.com/images/2015/02/19/arts/international/19iht-btnumbers19A/19iht-btnumbers19A-facebookJumbo-v2.jpg" /> The most important ones are title, description and image Note: after you make changes, you have to tell Facebook to scrape the updated content: https://developers.facebook.com/tools/debug/og/object/
Angular JS "pageslide-directive"

You have to add an controller to the panel and use it to load your content to the panel's items
