    copied!<p>I have a code that scrolls a growing page to the bottom (until it's not possible to scroll to the bottom).<br> When it's not possible, it scrolls to the top and the javascript code is finished.</p> <p>For example: imagine a timeline on facebook.<br> It's a growing page, so I can scroll it again and again until it's not possible to scroll (then I will be in: "BORN").</p> <p>So this is my code:</p> <pre><code>while (i &lt; elements.Count) { js.ExecuteScript("var timeId = setInterval( function() { if(window.scrollY&lt;(document.body.scrollHeight-window.screen.availHeight)) window.scrollTo(0,document.body.scrollHeight); else { clearInterval(timeId); window.scrollTo(0,0); } },5000);"); i++; } </code></pre> <p>I want to add 1 to <code>i</code> only when the <code>setInterval</code> is finished.</p> <p>I tried the next thing:</p> <pre><code>while (i &lt; elements.Count) { object a = js.ExecuteScript("setInterval( function() { if(window.scrollY&lt;(document.body.scrollHeight-window.screen.availHeight)) { window.scrollTo(0,document.body.scrollHeight); return '1'}; else { clearInterval(timeId); window.scrollTo(0,0); return '2'} },5000);"); while (a != '2') { // do nothing, this while will be ended when we arrived the bottom and // go back to the top } // all the page is loaded i++; </code></pre> <p>}</p> <p>but it doesn't work.. maybe there is a way to scroll to the bottom more and more and then to the top without using set interval? (but remember: it's a growing page that grows when you scroll it down and down.. </p> <p>How can I do it?</p>
