Javascript取消功能

Question

我在两个不同的页面中有一个滑块，两个滑块的js代码都写在一个js文件中问题是第二个javascript取消了第一个javascript的功能这里是我如何写它...

var mySubhome = 0;

function caballo() {
  var j;
  var z = document.getElementsByClassName("mySlydesProduct");

  console.log(z)

  for (j = 0; j < z.length; j++) {
    z[j].style.display = "none"
  }

  mySubhome++;

  if (mySubhome > z.length) {mySubhome = 1}
    z[mySubhome-1].style.display = "block";
    setTimeout(caballo, 2500);
  }
  window.onload = function(){
  caballo();
}


var myIndex = 0;

function carusel() {
  var i;
  var x = document.getElementsByClassName("mySlydesHome");

  console.log(x)

  for (i = 0; i < x.length; i++) {
      x[i].style.display = "none"
  }
  myIndex++;
  if (myIndex > x.length) {myIndex = 1}

  x[myIndex-1].style.display = "block";
  setTimeout(carusel, 1900);
}
