Tips for displaying a slideshow within a div using JavaScript

When the HTML loads for the first time, the div slideshow remains hidden until a button is clicked. Any suggestions on how to display the first div without requiring a button click?

var slideIndex = 1;
showDivs(slideIndex);

function plusDivs(n) {
  showDivs(slideIndex += n);
}

function showDivs(n) {
  var i;
  var x = document.getElementsByClassName("mySlides");
  if (n > x.length) {
    slideIndex = 1;
  }
  if (n < 1) {
    slideIndex = x.length;
  }
  for (i = 0; i < x.length; i++) {
    x[i].style.display = "none";
  }
  x[slideIndex - 1].style.display = "block";
}
<div class="row">
  <div class="col-xs-1">
    <button style="margin-top:70px" onclick="plusDivs(-1)">&#10094;</button>
  </div>
  <div class="col-xs-10">
    <div class="mySlides" v-for="review in reviews">
      <div class="row">
        <div class="col">
          <div class="card">
            <div class="card-body" style="padding:0px">
              <h5 class="card-title text-warning">{{review.name}}</h5>
              <p style="text-align:justify">{{review.review}}</p>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
  <div class="col-xs-1">
    <button style="margin-top:80px" onclick="plusDivs(1)">&#10095;</button>
  </div>
</div>

Answer №1

After reviewing the provided code, it appears that the functions are set up correctly. However, if the slider only works when the button is pressed, one solution could be to ensure that the slider is initialized after the page is fully loaded. This can be achieved by triggering the initialization function when the page has finished loading

window.addEventListener('load', (event) => {
    plusDivs(1);
});
