I tried using Local Storage to store a variable to determine if a button can be used or not. This however is not working at all like I expected. Why is the Item getting shown as "null" and why is the console.log not working?
Index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>index.html</title>
<script>
localStorage.setItem('status', 'unused')
console.log(localStorage.getItem('status'))
let usedButton = () => {
localStorage.setItem('status', 'used')
console.log(localStorage.getItem('status'))
window.location.replace('index2.html')
}
</script>
</head>
<body>
<button onclick="usedButton()">Use me</button>
</body>
</html>
index2.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>index2.html</title>
<script>
console.log(localStorage.getItem('status'))
let isButtonUsed = () => {
if(localStorage.getItem('status') == 'used'){
console.log('I was already used')
}
}
</script>
</head>
<body>
<button onclick="isButtonUsed()">Am I used?</button>
</body>
</html>
I tried making it so that the Button on index.html changes the localStorage variable status from 'unused' to 'used'. But on the 2nd page it is showing up as null and so the function is not working. I don't know how I can get a Button to work on one page and by clicking it disabling other buttons on other pages you redirect to.
Thank you in advance for your help.

I want to apply click event on anchor tags but when I click on first then get the data-id value of first and also redirect to href value similarly if I click on second link then get the data-id of second link only and redirect to its href value.

let link = body.querySelector('.link');
console.log(link);
}
</script>

</html>
This is the code I'm trying but when I click on any of the anchor tag then only first anchor tag accessing.
This is what I did and now it's working perfect.

I have an assignment where I have to change h1 to whatever is written in the input. I have to do this through making a function with getElementByID.
This is what I have so far
<!DOCTYPE html>

<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
<h1 id="Header">Change header</h1>
<p>Use the input to change the header.</p>
<input type="text" oninput="changeh1(this.value)" />
<script>
function changeh1(newtext) {
document.getElementById("Header").textContent=
}
</script>
</body>
</html>
You passed the value (newtext) to your function but never used it:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
<h1 id="Header">Change header</h1>
<p>Use the input to change the header.</p>
<input type="text" oninput="changeh1(this.value)" />
<script>
function changeh1(newtext) {
document.getElementById("Header").textContent=newtext;
}
</script>
</body>
</html>
Try changing your script to this:
function changeh1(newtext) {
document.getElementById("Header").innerText = newtext;
}
<script>
function changeh1(newtext) {
document.getElementById("Header").textContent = newtext;
}
</script>
The textContent API is useful to get and also set the text content of a node. In your original code, you did not set the content of the Node you were trying to modify (the header, h1). To fix it, just set it to the argument of the callback function you defined. In the DOM, you are passing this.value as the argument for newtext

This text is a link. How do I put this into the copy buffer (e.g. via navigator.clipboard.writeText()) so that when the user pastes it somewhere else it retains the link text as well as the link itself?
Thanks in advance!
When u use addEventListener, you can extract all information from the event.

<a class="link" href="https://stackoverflow.com/">Stackoverflow</a>
<script>
const linkComponent = document.querySelector('.link');
linkComponent.addEventListener('click', (event) => {
event.preventDefault(); // This will prevent the default action (going to link)
navigator.clipboard.writeText(`${event.target.innerHTML} - ${event.path[0].href}`);
});

the problem is that when i try to convet html to image js wont get load and i get a screenshot only from html
this is the result that i get:
this is what i expect:
I want to make a javascript program to activate something which requires some time to compute a animated screen pop ups while computing/loading. My Problem is I don't know how to achieve this in JS using async code. I have my approaches like this on where I just created a element into the website via javascript animated via CSS and when the computation was finished closed via javascript, but nothing happened. The idea was kind of like this:
document.getElementById("BTN").addEventListener("click",async function(){
document.getElementById("example").style.display = "block";
//Some Computing...
document.getElementById("example").style.display = "none";
});
#example{
display: none;
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<div id = "example">Lädt</div>
<button id = "BTN">Button</button>
</body>
</html>
So what is wrong with this approach?
It's likely that your entire code block is executed in one go, including setting the loading element visible and invisible afterwards, without giving the browser time to actually update the rendered page to show the loading element.
One way to modify your code would be:
document.getElementById("BTN").addEventListener("click",async function(){
document.getElementById("example").style.display = "block";
setTimeout(function() {
//Some Computing...
document.getElementById("example").style.display = "none";
}, 0);
});
This should allow the browser to update the page before going into the computation.
You should access after loading window.

})
};
</script>
