Evaluate responseText from Server.aspx

peace2007 · September 19th, 2007, 02:09 PM

Hi,

I need to evaluate the return result of a function from Server.aspx as following. But it doesn't work as I need

Code:

function getAjax()
{
    var XmlHttp;    
    //Creating object of XMLHTTP in IE
    try
    {
        XmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
    }
    catch(e)
    {
        try
        {
            XmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
        } 
        catch(oc)
        {
            XmlHttp = null;
        }
    }
    //Creating object of XMLHTTP in Mozilla and Safari 
    if(!XmlHttp && typeof XMLHttpRequest != "undefined") 
    {
        XmlHttp = new XMLHttpRequest();
    }    
    return XmlHttp;
}
function GetBanType()
{    
   rnd++;

    url = 'Server.aspx?action=GetBan&session=' + rnd ;
    var re = getAjax();

    re.onreadystatechange = function(){    
        if( re.readyState == 4 && re.status == 200 ) 
        {        
            if(re.responseText != "")
            {            
                if (re.responseText == "special value")
                {
                            ....

Actually, I call Server.aspx from many other functions as well and I set javascript control text to the return result of Server.aspx without any problem; but I cannot recognize the problem with above code.

Any idea is appreciated.

Well it would help if you showed what responseText contained and how this differs from what you expect.

the re.responseText contains:
"

 
 
 
 
 
 
 

"
while I expect a single word like "word" from it.

Seems like a problem with your web service then. Have you tried debugging with Fiddler to see the raw request and response?

Thanks John for the reply!
Since I'm new to fiddler I'm not getting what's going on there.

finally I found the problem but not the solution.
Actually, re.responseText returns:
"Gag

 
 
 
 
 
 
 

"
while I'm expecting only "Gag" word.
Could I know how I can subtract only the first word of the return result?

Thanks & Regards

I guess the Server.aspx page has many break tags, remove those tags from the Server.aspx or after Response.Write("Gag") call Response.End()

Hope it helps.
