Hi all,
I found a little script on the internet to load only a part of a page.
Now it uses javascript but it doesn't work in IE, firefox works fine and so does Opera, but IE doesn't (as always).
The Javascript code I use is the next:

var xmlhttp=false;
/*@cc_on @*/
/*@if (@_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject(”Msxml2.XMLHTTP”);
} catch (e) {
try {
xmlhttp = new ActiveXObject(”Microsoft.XMLHTTP”);
} catch (E) {
xmlhttp = false;
}
}
@end @*/

// branch for native XMLHttpRequest object (Mozilla & Safari)
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp = false;
}
}
//return xmlhttp;

/*
if (!xmlhttp && typeof XMLHttpRequest!=’undefined’) {
xmlhttp = new XMLHttpRequest();
} */

function calc_py(fragment_url, element_id) {
var element = document.getElementById(element_id);
element.innerHTML = "Loading …";
xmlhttp.open("GET", fragment_url+'?a=1', true);
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
element.innerHTML = xmlhttp.responseText;
}
}
xmlhttp.send(null);
}

Now, IE gives an error line 8 ("xmlhttp = new...."), can anyone, tell me whats wrong for IE with this script I found?

Thanks,
klaroen

Which "("xmlhttp = new....")," ?

there are quite a few

But then again the problem may well be that the lines that are meant for IE to see and initialise the XML object are commented out.

The one at line 8 .
I don't know that much about JS, but I shall give it a go uncommented

EDIT: I have tried it uncommented, but then both firefox and IE don't work.

Right!

and line 8 would happen to be???

var xmlhttp=false;
/*@cc_on @*/
/*@if (@_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject(”Msxml2.XMLHTTP”);
} catch (e) {
try {
xmlhttp = new ActiveXObject(”Microsoft.XMLHTTP”);
} catch (E) {
xmlhttp = false;
}
}
@end @*/

Line ° 8 as, shown above and earlier is my posts.
"xmlhttp = new ActiveXObject(”Microsoft.XMLHTTP”);"

Your E is capitalized in the line following. That's probably your issue.

There was a runtime-error.

Line:9
Error:Object is expected

PHP Code:

var xmlhttp=false;
/*@cc_on @*/
/*@if (@_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (E) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
@end @*/ 


Hmm, line 9 ...

You misunderstood me. catch (e) should be a lowercase e. My bad.

ok, changed it to lowercases, I don't get an error pupop nomore, but the refresh still won't work.. firefox does...

edit: This is the site where I got the original script: http://www.xuanau.com/2005/10/16/how...with-examples/

Ofcource changed a lot....

Wow, I can barely read that. I don't know what font that guy's using, but that's hideous.

klaroen, you just learned a very important lesson here: be very careful with the scripts you use/find online. They're quite often buggy and useless (as the example above illustrates). It's best to take what's online with a grain of salt, try it, deconstruct it, destroy it, get pissed off with it, and put it back together in a way that you understand so that you can best learn from it.

Can you link to what you've done now, and maybe we can go from there?

http://www.klaswebsite.be/risk/layout/games.php

Here you see a list of games out of a database, if you click Refresh only the table should refresh. Firefox does this, IE doesn't.

Your code seems to be a mish-mash of various bits of code.
This is what your remote call function should look like;

function calc_py (fragment_url, element_id) {
var element = document.getElementById(element_id);
var xmlHttp;
try
  {
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  try
    {
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    try
      {
      xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
    catch (e)
      {
      alert("XMLHttp Request Object initialise failed");
      return false;
      }
    }
  }
  xmlHttp.onreadystatechange=function()
    {
    if(xmlHttp.readyState==4)
      {
	element.innerHTML = xmlHttp.responseText;
      }
    }
	xmlHttp.open("GET", fragment_url, true);
  xmlHttp.send(null);
  }

Hmm, none of the browsers work with that code...

EDIT: I've noticed something important: If you open the page with IE, for the first time since you opened the browser, it is able to refresh the table one!! if you click refresh again after that, it doesn't... This can help no?

http://www.candsdesign.co.uk/articles/code/ajax/test/

Works for me in all my Windows browsers (FF2, IE6, NS7, Moz1.7) didn't work in Opera 7.54 which isn't that surprising seeing as XMLHttpRequest support wasn't added until ver 7.60

I have changed it to your script, and you can try it at the lni kI gave above, but it doesn't work for me...

Explain how it doesn't work.

BTW
name'btnJoin' isn't valid code.

and using single quotes is not valid for XHTML either they MUST be double quotes

Well, I click the refresh button, but it does nothing... does it with you?

What would you expect it to do? should it load something different?

If you want to test it, load up the page, make a change to the script it is loading from then click refresh. You should see your changes appear.

One other point, you have no form surrounding the inputs so your "Join Game" submit button will do nothing. And bear in mind that if and when you do add a form, your refresh button will submit the form as well as calling the AJAX function.

Now, the last script had that "Loading..." thing in it, and because I didn't see the table minimize I thought it just didn't do anything, but it does reload.
Now (again) with IE, there is something weird.
I made a change to the table, upload it, refresh the whole page and the adjustment is shown. But when I click refresh button, it goes back to the state of before the adjustments... is it in cache or so?

And about those forms, the whole page isn't done yet, I am only worring about the reload yet, the rest will be simple.
