the used language ( html and js )
var $count = document.getElementById("count"),
$textarea = document.getElementById("text"),
$maxlength = $textarea.getAttribute("maxlength");
$maxlength.oninput = function () {
$count.innerHTML = $maxlength - this.value.length;
};

Not $maxlength, use $textarea to listen oninput event.
var $count = document.getElementById("count"),
$textarea = document.getElementById("text"),
$maxlength = $textarea.getAttribute("maxlength");
$textarea.oninput = function () {
$count.innerHTML = $maxlength - this.value.length;
};

I want to print the name of user as same he enters in the input box.
You can try something like this. You need to add an event listener to a variable which represents the input element. The event it listens for is the input event. When any input happens the function fires which logs the value of the input element to the console.
const input= document.querySelector("#a")
input.addEventListener('input', function(event){
console.log(event.target.value);
});
<input id="a" placeholder="enter here..." >
use event keyup
addEventListener('keyup',test)
function test(){
let x = document.getElementById('a').value
console.log(x)
}

In your text.addEventListener("input", updateCount()); assignment you did not assign the function updateCount to the input event of the selected element but instead you executed it once and assigned the non-existent return value of the function call to the event.
And in the function itself you will need to put (=assign) the calculated count somewhere too:
let text = document.querySelector('#text');
let count = document.querySelector('#count');
text.addEventListener("input", updateCount);
function updateCount(ev){
count.textContent=ev.target.value.length;
}

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

</html>
ev.target.value.length gets the current length of the <textarea> element and count.textContent= assigns it to the target <span>.
A better way is by subscribing to the keyup event and getting the value from the scope using this keyword
function characterCount() {
document.getElementById('text').onkeyup = function () {
document.getElementById('count').innerHTML = this.value.length;
};
}

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.

<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)
}

});

Try adding
display:none;
to #test in your style.css.
Alternatively, you could add it in the tag as well with:
<div id="test" style="display:none">
see below:
var test = $('#test'),
toggle = $('#toggle');
toggle.click(function() {
test.slideToggle(1000, function() {
});
});
