How can I multiply my element created with JS

                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%;
                    height                  : 100vh;
                    display                 : flex;
                    justify-content : center;
                    align-items         : center;
                }

                .mainContainer {
                    position                 : relative;
                    width                    : 440px;
                    height                   : 200px;
                    display                  : flex;
                    justify-content  : center;
                    align-items          : center;
                    justify-content  : space-around;
                    border-radius    : 5px;
                    border                   : 1px solid black;
                    background-color : silver;
                }

                .itemContainer{
                    position                : relative;
                    width                   : 130px;
                    height                  : 130px;
                    display                 : flex;
                    justify-content : center;
                    align-items         : center;
                    border-radius   : 50%;
                }

                .item {
                    position                : absolute;
                    width                   :2px;
                    height                  :100%;
                    display                 : flex;
                    justify-content : center;
                }

                .item::before {
                    top              : 0px;
                    content      : '';
                    position     : absolute;
                    background : var(--background, black);
                    width        : var(--width, 2px);
                    height       : 10px;
                    text-align : center;
                }

                .item::after {
                    bottom       : 0px;
                    content      : '';
                    position   : absolute;
                    background : var(--background, black);
                    width        : var(--width, 2px);                       
                    height       : 10px;
                }

            <div class="mainContainer">
                <div class="itemContainer">H</div>
                <div class="itemContainer">M</div>
                <div class="itemContainer">S</div>
            </div>

 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');
