<div>
<input type="button" onclick="buyStuffWithPoints()" value="Buy Sword(2500)!" />
</div>
</body>
</html>
So currently what happens is when I run it, it prompts me to enter amount of points, then it shows two buttons, "Start!" and "Buy Sword(2500)!". Then after clicking start, the next page shows 4 pictures of the items to buy.
What I want to happen is, after I enter the amount of points, I only want it to show the "Start!" button. Then on the NEXT page, the same page where the pictures show up, I want to show the "Buy Sword" button.
I understand why it's doing this, I just have no idea how to change it. Can anyone help me with this?
You must close your p tags and you should avoid document.write

i cant find a way to send the text inside page2 to page 1
There are many ways that you could achieve this, but I'll show you just one. You can easily pass data between pages using query parameters, which are essentially pieces of data appended to the end of a URL.
In order to utilize these, you would need to redirect to your index.html page whenever the user presses the button in the control.html page. Fortunately, this can be done by adding an event listener to your Submit button.
Here is the code below:
control.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" />
</head>
<body>
<form>
<p>Enter stuff here:</p>
<input type="text" id="text-input" name="text" />
<input type="submit" id="submit-button"></input>
</form>
<!-- continue document... -->
<script src="src/control.js"></script>
</body>
</html>
src/script.js
const queryString = window.location.search;
const queryParams = new URLSearchParams(queryString);
const message = queryParams.get("text");
console.log(message);
// continue file...
src/control.js
const button = document.getElementById("submit-button");
button.addEventListener("click", handleText);
function handleText(event) {
event.preventDefault();
const text = document.getElementById("text-input").value;
const currentURL = window.location.pathname;
const currentDir = currentURL.substring(0, currentURL.lastIndexOf("/"));
window.location.replace(currentDir + "/index.html?text=" + text);
}
Hope this helps!
I'm trying to create a trigger button that, when pressed, will display a value from an excel cell in alert box or on the page.
below is all I could get, but it doesn't display anything on the page.
update: I managed to do this using ActiveX, but I don't want to use this library for some reasons. Do you have any idea how I could do it?
update code:

I am making a news style app that uses the newsapi. I want to ask how do I get search functionality to work, how do I get the HTML input box to display the results of what you type in. I have tried a few times to get it to work but can't. Any suggestions appreciated.

Okay so I don't have an API key to the news API that you are using but I instead used a free Rick & Morty API to answer your question.
I had to make some alterations to your code in order to get it to work with my API but I added a bunch of comments in the code snippet to hopefully make it make a bit of sense why I made the changes and also how you can change it back to work with your news API. Good luck!
const characters = document.querySelector(".characters");
const searchInput = document.querySelector("#search");
characters.innerHTML = "";
// We also changed this here to include the actual act of fetching the data - you would instead do your news fetch here.
function handleClick(e) {
let url = "https://rickandmortyapi.com/api/character/";
// This here maps a HTMLCollection into a JavaScript array and then removes previous children if they exist,
// this is to clear the list items prior to a new search.
if (characters.children.length > 0)
Array.from(characters.children).forEach((child) => child.remove());
// If we provide a search input include it in the URL - note the only search we can do here is for pages so the input is now a number.
// This is where you would instead change your news URL and append the "searchInput.value" into the "search section" like so:
//
// const url =
// "https://newsapi.org/v2/everything?" +
// `q=${searchInput.value}&` +
// "from=2021-06-02&" +
// "sortBy=popularity&" +
// "apiKey=****************";
//
// Note that in order to use a variable you need backticks as your quote delimeter. See like `${variable}` instead of '' or "".
if (searchInput.value)
url =
"https://rickandmortyapi.com/api/character/" +
`?page=${searchInput.value}`;
let req = new Request(url);
fetch(req)
.then(function (response) {
return response.json();
})
.then((data) => {
console.log(data);
// I removed your image mapping here because I had no image from this free Rick and Morty API but I hope you get the idea.
data.results.map((character) => {
let li = document.createElement("li");
let a = document.createElement("a");
a.setAttribute(
"href",
"https://rickandmortyapi.com/api/character" + `/${character.id}`
);
a.setAttribute("target", "_blank");
a.textContent = `${character.name}`;
li.appendChild(a);
characters.appendChild(li);
});
});

I'm passing an array of strings to be displayed as html text inside a
my_arr = ["PRODUCT", "SHAMPOO1", "SHAMPOO2", "SHAMPOO3", "SHAMPOO1"]
which is displayed as :
PRODUCT, SHAMPOO1, SHAMPOO2, SHAMPOO3, SHAMPOO1.
What I want to do is make these clickable. And when I click on one of these words I want that word to be displayed below it.
What's the cleanest way to do this?
Passing the array in the <a> tag isn't working for me.
you can add it to the DOM, then loop your array to the li under ul

var str = "<ul>";
my_arr.forEach(function (product) {
str += "<li> <a href='/'>" + product + "</a> </li>";
});
str += "</ul>";
document.getElementById("products").innerHTML = str;

I am trying to display random numbers from 1 to 7. I do not want them to repeat and I want to display every number. I've written my JS code inside script tag. I want to get a random number whenever button is clicked, instead I'm getting error
Uncaught TypeError: Cannot set property 'innerHTML' of null

After document.write(...); there is no other elements in the page expect the passed text.
It is why when you trying to find then document.getElementById("demo") it's cannot find, and return null. (then throw error, when you trying to access its innerHTML)
If you trying to append something to the page you should use document.body.innerHTML += "...".
About the algorithm itself - you can use:
[1,2,3,4,5,6,7].sort(function() { return .5 -Math.random();});
It will shuffle the array randomly.
Your document.write(..) is breaking it.
You can try:
document.body.innerHTML += '<br />';
document.getElementById("demo").innerHTML = `Question No : ${q[random]}`;
document.body.innerHTML += '<br />';
