Start & stop slideshow with same button?

[toneemontana]

Hello to all,

can someone please tell me how to start and stop with the same button in my slide show? My slideshow already runs when I click my "View Show" button, I set up my function so that when I click the "View Show" button, the text on the button changes to "Stop", and the slide show starts. I don't know how to make the slide show stop if I click the button again.

What program is this you are referring to? I am very confused!!

I apologize...I am using JavaScript to make a slideshow for my class. Here is the script I am using to run my show:

Code: Select all

var imagenumber = 1;
var totalimages = img_info.length - 1;
function showSlide(direction){
 if (direction == "next"){
  (imagenumber == totalimages) ? imagenumber = totalimages :
 imagenumber++; 
  }else{
  (imagenumber == 0) ? imagenumber = 0 :
 imagenumber--;
 }
 if (direction == "next" && document.slidecontrols.repeater.checked){
  (imagenumber == totalimages) ? imagenumber = 0 :
  imagenumber++;
  }  
 if (document.images){
  document.mainframe.src = img_info[imagenumber].fname;
  document.getElementById('img_title').innerHTML = img_info[imagenumber].title;
  document.getElementById('img_date').innerHTML = img_info[imagenumber].date;
  document.getElementById('img_time').innerHTML = img_info[imagenumber].time;
  document.getElementById('img_camera').innerHTML = img_info[imagenumber].camera;
  document.getElementById('img_descr').innerHTML = img_info[imagenumber].descr;
 }
}
function slideShow(){
 setInterval("showSlide('next')", 7000);
 document.slidecontrols.showbutton.value = "Stop";}

So I have my "View Show" button with an onclick handler to run the slide show, and when I click the button to start the show, the text turns to "Stop" but I cant figure out how to add a function to click the same button to stop the show. Right now, if the show is going, and I click the button again, it just keeps going. And something else I've noticed is that when I have my cycle checkbox checked, it skips some of my slides.

So this would be best to put it in the JavaScript forum...huh? No worries, I moved it there for ya!!

What triggers the slideshow?

[toneemontana]

I have a button "View Show" with onclick="slideShow('next')"

here is the slideShow function:

Code: Select all

function slideShow(){
 setInterval("showSlide('next')", 7000);
 document.slidecontrols.showbutton.value = "Stop";}
 
 
And here is the showSlide function:
 
var imagenumber = 1;
var totalimages = img_info.length - 1;
function showSlide(direction){
 if (direction == "next"){
  (imagenumber == totalimages) ? imagenumber = totalimages :
 imagenumber++; 
  }else{
  (imagenumber == 0) ? imagenumber = 0 :
 imagenumber--;
 }
 if (direction == "next" && document.slidecontrols.repeater.checked){
  (imagenumber == totalimages) ? imagenumber = 0 :
  imagenumber++;
  }  
 if (document.images){
  document.mainframe.src = img_info[imagenumber].fname;
  document.getElementById('img_title').innerHTML = img_info[imagenumber].title;
  document.getElementById('img_date').innerHTML = img_info[imagenumber].date;
  document.getElementById('img_time').innerHTML = img_info[imagenumber].time;
  document.getElementById('img_camera').innerHTML = img_info[imagenumber].camera;
  document.getElementById('img_descr').innerHTML = img_info[imagenumber].descr;
 }
}

I don't know if you needed all of that, if not, sorry.
