TSmooth40 Posted June 17, 2016 Share Posted June 17, 2016 From W3.CSS Slideshow webpage: http://www.w3schools.com/w3css/w3css_slideshow.asp. Is there a way where I can utilize both the manual and automatic script within a single slideshow? I want the slideshow to move automatically as well as have the capability to change the slides manually. Thanks you for your assistance. 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.style.display = "none"; } x[slideIndex-1].style.display = "block";} var slideIndex = 0;carousel();function carousel() {var i;var x = document.getElementsByClassName("mySlides");for (i = 0; i < x.length; i++) { x.style.display = "none"; } slideIndex++;if (slideIndex > x.length) {slideIndex = 1} x[slideIndex-1].style.display = "block"; setTimeout(carousel, 2000); // Change image every 2 seconds} Link to comment Share on other sites More sharing options...
davej Posted June 17, 2016 Share Posted June 17, 2016 Well, this gets confusing because I don't know what you are using for html. In the slideshow here... http://www.w3schools.com/howto/howto_js_slideshow.asp With the html from the link above -- the following code works both manually and automatic... 'use strict'; var slideIndex = 1; function plusSlides(n) { showSlides(slideIndex += n); } function currentSlide(n) { showSlides(slideIndex = n); } function showSlides(n) { //alert('showslides('+ n +')\nslideIndex='+slideIndex); var i; var slides = document.getElementsByClassName("mySlides"); var dots = document.getElementsByClassName("dot"); if (n==undefined){n = ++slideIndex} if (n > slides.length) {slideIndex = 1} if (n < 1) {slideIndex = slides.length} for (i = 0; i < slides.length; i++) { slides[i].style.display = "none"; } for (i = 0; i < dots.length; i++) { dots[i].className = dots[i].className.replace(" active", ""); } slides[slideIndex-1].style.display = "block"; dots[slideIndex-1].className += " active"; setTimeout(showSlides, 5000); // Change image every 5 seconds } 1 Link to comment Share on other sites More sharing options...

TSmooth40 Posted June 20, 2016 Author Share Posted June 20, 2016 davej,I am also used the HTML that changes the images manually. Thanks! <a class="w3-btn-floating" onclick="plusDivs(-1)">❮</a><a class="w3-btn-floating" onclick="plusDivs(+1)">❯</a> Link to comment Share on other sites More sharing options...
dsonesuk Posted June 20, 2016 Share Posted June 20, 2016 My code covers all versions, it pauses the slideshow on hover of prev/next, dots, thumbnails preventing conflict with auto forward slide code, so you don't jump two places or more slides.

TSmooth40 Posted June 20, 2016 Author Share Posted June 20, 2016 davej, When the page is initially rendered all of the images are visible, until I click on the arrow to change the image. However when the page is on one image it does not render to the next image. The displayed image continues to fade in and out, not changing to the next imagine.What am I missing or overlooking?

davej Posted June 20, 2016 Share Posted June 20, 2016 Did you try Dsonesuk's code above? I confused the issue by introducing a different example that used different CSS. Link to comment Share on other sites More sharing options...
TSmooth40 Posted June 20, 2016 Author Share Posted June 20, 2016 No I haven't tried Dsonesuk's yet. The code is in a different environment, which means I have to hand code everything in. Yours is a lot shorter than Dsonesuk's code. What is the CSS you're using? Link to comment Share on other sites More sharing options...
davej Posted June 20, 2016 Share Posted June 20, 2016 My code was based on the example on this page... http://www.w3schools.com/howto/howto_js_slideshow.asp Link to comment Share on other sites More sharing options...

james99 Posted July 3, 2016 Share Posted July 3, 2016 Hello, dsonesuk! I'm using your code and i'm trying to add a link on every slide using this code but it makes the text show in every image <div class="w3-display-bottomleft w3-large w3-container w3-padding-16 w3-black"> Trolltunga, Norway </div> Link to comment Share on other sites More sharing options...
dsonesuk Posted July 3, 2016 Share Posted July 3, 2016 That is not a link, and seems not to have any relation to code provided? Link to comment Share on other sites More sharing options...

dsonesuk Posted July 13, 2016 Share Posted July 13, 2016 That is done differently there is a surrounding container div around every image with class .'mySlides' which originally was applied to only the images themselves, and within this surrounding parent div container element the caption is placed within it. The 'mySlides' class is targeted to control slide action, so the caption div will appear individually within each individual parent div container with class 'mySlides' when set to display. 1 Link to comment Share on other sites More sharing options...

james99 Posted August 5, 2016 Share Posted August 5, 2016 is there a way to convert the images into background images without messing up the theme?? Link to comment Share on other sites More sharing options...
dsonesuk Posted August 6, 2016 Share Posted August 6, 2016 Why? Its more complicated, background-images parent element can't determine size of background-images to accommodate them, you would have identify that beforehand. You would have to apply each image as css background-image each time manually for each parent container unless you can use server side to read images from specific folder and do this dynamically.

m.s_shohan Posted November 12, 2016 Share Posted November 12, 2016 dsonesuk's code works as I expected. Thank you. :Happy: Link to comment Share on other sites More sharing options...
joschro Posted December 14, 2016 Share Posted December 14, 2016 davej, the code works, but when I start pressing the next/prev arrows, the timing and order of the slideshow gets messed up. Is there a way to fix it, so the timing remains consistent, and it doesn't jump around to random slides? Link to comment Share on other sites More sharing options...
