I'm trying to follow a video, but the button isn't working. I cannot press the button. How do I fix my code?
My code
function increment() {
console.log("added");
}

I'm not certain where to go from here
Your code seems running fine, I just added the increment function. You'll see the button work. :)
function increment() {
document.getElementById("count-el").innerHTML = eval(document.getElementById("count-el").innerHTML) + 1;
}

Maybe I wrote something wrong?
I have an HTML file linked to a script. A button defined in the HTML has an onclick function 'incrementLabel()' but the function in the script throws the warning:
'incrementLabel' is declared but its value is never read.
function incrementLabel() {
var text = document.getElementById("testLabel").textContent;
document.getElementById("testLabel").innerText = (parseInt(text) + 1);
}

<button onclick="incrementLabel()">Test</button>
<label id="testLabel">0</label>

I can't find any solutions to the problem other than writing the function in a in HTML. Any help would be much appreciated.
Thanks!

This works perfectly fine. Check if you are importing your JS script correctly.
You can put the javascript code into a before the closing tag .

}
</script>

Some of online tools like https://playcode.io don't recognise your code but I have tested in vscode and works fine.
Maybe have to use other online tool or can test if you have imported the code well with a console.log("Works fine") into your javascript file.
Sorry for my english.

Hi I am trying to add a start button via jquery to appear when the page loads. However, the button is not loading.
Here is my code:

I have an html file and I want to grab the text that is entered in the input field using javascript. I have tried a few different ways but nothing seems to be working properly. Here is the code that I have right now.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<input type="text" id="searchingterm">
<form>
<input type="text" id="search">
</form>
<script>
$(document).ready(function(){
var searched = document.getElementById("search").value;
console.log(searched)
})
</script>
</body>
</html>
i also tried using jquery but that didnt do anything either.
basically, the problem is that you are not assigning anything to that input and also you dont have a function to trigger the search.
your code was right, you just needed to change it a little bit.
function search() {
var searched = document.getElementById("search").value;
console.log(searched)
}
