title: JavaScript Infinitely Looping slideshow with delays?
body: <p>How do I make an infinite loop in JavaScript? I'm trying to make a slideshow, which I have working, but I can't get it to loop. I can't even get it to loop twice. </p>
  
  <p>The code I'm using right now is </p>
  
  <pre><code>window.onload = function start() {
      slide();
  }
  function slide() {
      var num = 0;
      for (num=0;num&lt;=10;num++) {
          setTimeout("document.getElementById('container').style.marginLeft='-600px'",3000);
          setTimeout("document.getElementById('container').style.marginLeft='-1200px'",6000);
          setTimeout("document.getElementById('container').style.marginLeft='-1800px'",9000);
          setTimeout("document.getElementById('container').style.marginLeft='0px'",12000);
      }
  }
  </code></pre>
  
  <p>Without the for thing in there, it does go through once. When I put in a for, it either makes Firefox lock up, or just loops once. I'm sure this is a really simple thing to do, and even if it has to be loop 1,000,000 times or something instead of infinite, that'd work fine for me. </p>
  
  <p>Also, I don't want to use jQuery or something that someone else created. I'm learning JavaScript, and this is partially to help me learn, and partially because I'm trying to make as many HTML5-based systems as I can.</p>
  
  <p>EDIT: I think the reason it's freezing is because it executes the code all at once, and then just stores it in a cache or something. What I want it to do is go through this once, then start at the top again, which is what I've always thought loops where for. In "batch" (command prompt) scripting, this could be done with a "<code>GOTO</code>" command. I don't know if there's an equivalent in JS or not, but that's really my goal.</p>
