innerHTML of frame with an FTP location?

I need to access the "document.body.innerHTML" of a frame when the frame location is an ftp site.

I can do it as long as the location of the frame is an http page, but when I make it an ftp site, the frame no longer has a "document" object.

Here is the code that is giving me problems:

** Main Frameset Page **
<html>
<head>
<script language="javascript">
<!--
function logon(user,pw,server) {
  bottomframe.location = 'ftp://' + user + ':' + pw + '@' + server;
  return;
}
function check() {
  alert(bottomframe.document.body.innerHTML);
}
//-->
</script>
</head>

<frameset name="frameset" rows="*,100">
  <frame name="topframe" src="logon.html">
  <frame name="bottomframe" src="blank.html">
</frameset>


** logon.html Page **
<html>
<head>
</head>
<body>
<form name="logonForm" action="SelectPage.html">
<b>Logon to Web Site</b>
<br>
Username:<input name="username" type="text">
<br>
password:<input name="password" type="password">
<br>
Web Server:<input name="server" type="text">
<br>
<input type="button" value="Logon" onClick="parent.logon(document.logonForm.username.value,document.logonForm.password.value,document.logonForm.server.value);">
<br>
<input type="button" value="Show innerHTML" onClick="parent.check();">
</form>
</body>
</html>

** blank.html Page **
<html>
<head>
</head>
<body>
The innerHTML is here
</body>
</html>

"I can do it as long as the location of the frame is an http page"

not all http page but only pages that you own or pages that grants you full access. try setting the bottom frame to www.yahoo.com and see what i mean.

this also applies to your problem.

third:

You are right (although the error message for pages that I don't own says "access denied" instead of "no such interface supported" which is what it says for ftp pages).

steven M:

You are right, I want to make an HTML editor using javascript.  This means I need the browser to be able to upload and download files.

"no such interface supported"

therefore these statement generally means that accessing documents from http to ftp is not supported by browsers although http can view the page but is on a protected mode (i.e. readonly).

for creating javascript-based HTML editor, you will find this link very useful,

I've discovered a way to get the contents of a file from a web server using javascript.  Here is what my new logon function looks like.

function logon(user,pw,server) {
  // the user and pw variables are not needed
  // because this uses HTTP instead of FTP,
  // the server variable can contain a complete URL.
  var xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
  xmlHttp.open("GET", server, false);
  xmlHttp.send();
  bottomframe.document.body.innerHTML=xmlHttp.responseText;
 return;
}

This question has been abandoned. I will make a recommendation to the moderators on its resolution in a week or so. I appreciate any comments that would help me to make a recommendation.
 
In the absence of responses, I may recommend DELETE unless it is clear to me that it has value as a PAQ. Silence = you don't care
