JAVAX problem with special parameter

[celia05es]

Hello,
I am using the following JAVAX stuff:

....
[COLOR=red][plist="cname="+fieldName+"&cvalue="+cvalue;
 
[b]url="update_field.jsp?"+plist;[/b]
makeRequest(url);[/color]
}

function makeRequest(url)
{
  http_request = false;
  if (window.XMLHttpRequest)  // Mozilla, Safari,...
  {
    http_request = new XMLHttpRequest();
    if (http_request.overrideMimeType)
    {
      http_request.overrideMimeType('text/xml');
    }
  }
  else
  {
    if (window.ActiveXObject)  // IE
    {      try
      {
        http_request = new ActiveXObject("Msxml2.XMLHTTP");
      }
      catch (e)
      {
        try
        {
          http_request = new ActiveXObject
        } catch (e) {}
      }
    }
  }

  if (!http_request)
  {
     alert('Giving up. Cannot connect');
     return false;
  }
  http_request.onreadystatechange = alertContents;
  http_request.open('GET', url, true);
  http_request.send(null);
}


function alertContents()
{
  if (http_request.readyState == 4)  // COMPLETE
  {
    if (http_request.status == 200)
    {
      var values = http_request.responseText;
      var ier=trim(values);
      if (ier != "0")
      {
        alert(ier);
      }
    }
    else
    {
       alert("Problem with the request.\nTry it again.\nIf the problem persists,
 consult the database administrator");
    }
  }
}

The problem arises when the cvalue parameter is a special character like "%" or "#" => I get a http_request.status =500

How can I solve this problem?

Thank you

have you tried escaping the cvalue?

plist= "cname=" + escape(fieldName) + "&cvalue=" + escape(cvalue);

It does work!!! You are the best. Thank you so much!

By the way, I am having problem with the AJAX code with Explorer.... sometimes it does not work correctly. I mean that I receive a http_request = 200 (completed) but I know that the .jsp file is not called !!! Strange hey!
I have been told that I could fix the problem forcing the IE to repaint... is this true ? If so, how should I do it?

forcing the IE to repaint

If you mean refresh the page, then this would work:

location.reload(true);

If you want to force the browser to reshow the current content without getting it again from the server, I imagine you'd have to do something like:

1. Hide all content (see below),
2. Wait a small amount of time to guarantee it was hidden,
3. Re-show all content.

The hiding can be done like this:

document.getElementsByTagName('body')[0].style.display = 'none';

and the showing by using "block" instead of "none".

Hope this helps,
Dan

Thanks for the response.
Where should I put the above code?

 

[BillyRayPreachersSon]

Wherever you want the repaint to be called from.

Actually, are you aware of this king of problem with Explorer?
I mean when using JAVAX?
Sometimes, though the http_request.status is 200 (which should mean that the request has been completed)... the file has not been called!!!
I know that because the called file write into a debug file and there is nothing.

THe problem is that is does not always happens!
