                container = document.querySelector('.itemContainer');       

                for(i = 0; i < 30; i++){
                    container.innerHTML += '<div class="item"></div>';
        

                    if((i % 5) == 0){ 
                        document.querySelectorAll('.item')[i].style.setProperty("--width", 4+"px");
                    }       

                    document.querySelectorAll('.item')[i].style.transform = "rotate(" + i * 6 + "deg)";     
                }
                * {
                    margin       : 0;
                    padding:   : 0;
                    box-sizing : border-box;
                }

                body {
                    width                   : 100%;

                    border-radius    : 5px;
                    border                   : 1px solid black;
                    background-color : silver;
                }

                .itemContainer{

 I want to use my "Clock Dial" drawn with JS in different Divs. 

Couldn’t multiply it. I’m confused. Thanks for all efforts to help.

Each div will show the parts of a clock: Hour, Minute, Second.

Thanks for any efforts to help. Hope the code is clear enough.

I have pasted “lorem” text below to send my question? ! 🙂

Answer

You have to create a function and reuse the code like this

Update HTML with:

<div class="mainContainer">
  <div id="h" class="itemContainer">H</div>
  <div id="m" class="itemContainer">M</div>
  <div id="s" class="itemContainer">S</div>
</div>

JS:

function makeCircle(circle) {
  container = document.querySelector('#'+circle);

  for(i = 0; i < 30; i++){
    container.innerHTML += '<div class="item '+circle+' "></div>';
    if((i % 5) == 0){ 
      document.querySelectorAll('.item.'+circle)[i].style.setProperty("--width", 4+"px");
    }       
    document.querySelectorAll('.item.'+circle)[i].style.transform = "rotate(" + i * 6 + "deg)";     
  }
}

makeCircle('h');
makeCircle('m');
makeCircle('s');
