creating and appending variables inside a for loop

I’m trying to dynamically make an unordered list using javascript, where I just have to list the number of items that I want and it will display it in the list.

example input prompt "how many list items would you like?" if we input 2 and enter
it should return

  <ul>
    
    <li>hi</li>
    <li>hi</li>
    
    </ul>

I’ve simplified the HTML and javascript but i tried wrap the append and create variables in a for loop and nothing happened.
heres the code html :

    const numberofitemsel = document.getElementById('num-of-navitems');
        const numberofitems = parseInt(numberofitemsel.value);
    
        const body = document.body;
    
    
        const savebtn = document.getElementById('save');
       savebtn.addEventListener('click',()=>{
        let ul =document.createElement("ul");
    // append to body 
    
    
    
       body.append(ul);
       // create list items 
       
       for(var i=0;i<=numberofitems;i++){
        let li=document.createElement("li");
        li.innerText="hi";
 
 
 
 
 
    // append to ul
    ul.appendChild(li);
   }
});

   

 <main>
      <h4>how many list items do you want?</h4>
      <input type="number" id="num-of-navitems">
      <button type="button" id="save">save</button>
    </main>

so the output I want is the if I input 3 into my input box I want three list items:

<ul>

<li>hi</li>
<li>hi</li>
<li>hi</li>

</ul>

>Solution :

You should use for loop in the savebtn.eventListener:

for(let i=0;i<Math.floor(Number(numberofitemsel.value));i++) {
 let li = document.createElement("li");
 li.innerText = "hi";
 // append to ul
 ul.appendChild(li);
  }

The other parts of your code are OK.
