Running 3 slideshows on the same page

I'm trying to run 3 slideshows on one page. I tried the following the code, But when I click the buttons on the 3rd slideshow, It changes the images on the 2nd slideshow. Please help me to solve this issue

var slideIndex = [1, 1, 1];
var slideId = ["mySlides1", "mySlides2", "mySlides3"]
showDivs(1, 0);
showDivs(1, 1);
showDivs(1, 2);

function plusDivs(n, no) {
  showDivs(slideIndex[no] += n, no);
}

function showDivs(n, no) {
  var i;
  var x = document.getElementsByClassName(slideId[no]);
  if (n > x.length) {slideIndex[no] = 1}
  if (n < 1) {slideIndex[no] = x.length}
  for (i = 0; i < x.length; i++) {
    x[i].style.display = "none";  
  }
  x[slideIndex[no]-1].style.display = "block";  
}
.mySlides {display:none;}
