Hi Experts,<br />
<br />
Here is my code:<br />
<br />
&lt;html xmlns=&quot;<a href="http://www.w3.org/1999/xhtml" rel="ugc">http://www.w3.org/1999/xhtml</a>&quot;&gt;<br />
&lt;head&gt;<br />
&lt;meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=windows-1251&quot; /&gt;<br />
&lt;title&gt;Untitled Document&lt;/title&gt;<br />
&lt;script type=&quot;text/javascript&quot;&gt;<br />
var timer_id;<br />
function scroll_iframe(frm,inc,dir)<wbr /> {<br />
&nbsp; if (timer_id) clearTimeout(timer_id);<br />
&nbsp; if (window.frames[frm]) {<br />
&nbsp; &nbsp; if (dir == &quot;v&quot;) window.frames[frm].scrollB<wbr />y(0, inc);<br />
&nbsp; &nbsp; else window.frames[frm].scrollB<wbr />y(inc, 0);<br />
&nbsp; &nbsp; timer_id = setTimeout(&quot;scroll_iframe(<wbr />'&quot; + frm + &quot;',&quot; + inc + &quot;,'&quot; + dir + &quot;')&quot;, 20);<br />
&nbsp; }<br />
}<br />
<br />
function stopScroll() { if (timer_id) clearTimeout(timer_id); }<br />
&lt;/script&gt;<br />
&lt;/head&gt;<br />
<br />
&lt;body&gt;<br />
some randon content<br />
&nbsp; &lt;iframe src=&quot;file:///C:/test/sampl<wbr />eframecont<wbr />ent.htm&quot; name=&quot;IFrame&quot;&gt;&lt;/iframe&gt;<br />
&lt;br/&gt;<br />
some more content<br />
&lt;button type=&quot;button&quot; onclick=&quot;scroll_iframe('IF<wbr />rame',1,'v<wbr />');&quot;&gt;scrol<wbr />l frame&lt;/button&gt;<br />
&lt;/body&gt;<br />
&lt;/html&gt;<br />
<br />
This works fine, &nbsp;but I need to know when the scrollbar reaches the end of the document to automatically popup a message for example (this is the end).<br />
<br />
Hope you see what I need.<br />
<br />
Thanks in advance for your help.

Hi Experts,

Here is my code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1251" />
<title>Untitled Document</title>
<script type="text/javascript">
var timer_id;
function scroll_iframe(frm,inc,dir) {
  if (timer_id) clearTimeout(timer_id);
  if (window.frames[frm]) {
    if (dir == "v") window.frames[frm].scrollBy(0, inc);
    else window.frames[frm].scrollBy(inc, 0);
    timer_id = setTimeout("scroll_iframe('" + frm + "'," + inc + ",'" + dir + "')", 20);
  }
}

function stopScroll() { if (timer_id) clearTimeout(timer_id); }
</script>
</head>

<body>
some randon content
  <iframe src="file:///C:/test/sampleframecontent.htm" name="IFrame"></iframe>
<br/>
some more content
<button type="button" onclick="scroll_iframe('IFrame',1,'v');">scroll frame</button>
</body>
</html>

This works fine,  but I need to know when the scrollbar reaches the end of the document to automatically popup a message for example (this is the end).

Hope you see what I need.

IFrame scrolling

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
