Automatic SlideShow Issues


TDAdvocate

Recommended Posts

I am working to create an Automatic (Animated) and Manual (Indicators) SlideShow but having issues even getting the bases working at all. I have not started work on the Manual SlideShow yet but here is a direct link for the Automatic Animated SlideShow tutorial. When I use the w3.css and try to put the code into a CSS file separate from the HTML file it will initially load all the images into the view animated but separate from one another. I have placed the code below for further inspection and suggestions. Thank you in advance to anyone who helps me regarding this issue!

	</body>


</html>

CSS

@charset "utf-8";

/* Slideshow Carousel Effect */
style {
  .mySlides {display:none;}
}

/* Slideshow Navigation Menu Style*/
/*
style {
  .mySlides {display:none}
  .w3-left, .w3-right, .w3-badge {cursor:pointer}
  .w3-badge {height:13px;width:13px;padding:0}
}
*/

JS

//Slideshow Carousel Effect
var myIndex = 0;
carousel();

function carousel() {
    var i;
    var x = document.getElementsByClassName("mySlides");
    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(carousel, 2500);    
}

//Slideshow Naviagtion Effect
/*
var slideIndex = 1;
showDivs(slideIndex);

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

function currentDiv(n) {
  showDivs(slideIndex = n);
}

function showDivs(n) {
  var i;
  var x = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("demo");
  if (n > x.length) {slideIndex = 1}    
  if (n < 1) {slideIndex = x.length}
  for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";  
  }
  for (i = 0; i < dots.length; i++) {
     dots[i].className = dots[i].className.replace(" w3-white", "");
  }
  x[slideIndex-1].style.display = "block";  
  dots[slideIndex-1].className += " w3-white";
}
*/

EDIT: When checking the Console in Google Chrome I get the following error: 

script.js:13 Uncaught TypeError: Cannot read property 'style' of undefined
    at carousel (script.js:13)
    at script.js:3
