Response.Write will simply add the text to the output. JavaScript will have to scan the html to find it. You would be better setting a label.text value instead of using Response.Write so that the javascript can get the label value.

What exactly are you trying to do?

Add a label or hidden field to your page then in C# set it's value. Then in JavaScript you can use document.getElementById() or jquery to get the value.

suppose name of this page is IsFoderExists.asp

VB

<![CDATA[<%
dim fs
set fs=Server.CreateObject("Scripting.FileSystemObject")
if fs.FolderExists("D:\java\x.java.txt")=true then
  response.write("Folder c:\asp exists!")
else
  response.write("Folder c:\asp does not exist!")
end if
set fs=nothing
%>

write javascript to call this page...

C#

function IsFolderExists()
    {
        if (window.XMLHttpRequest)
        {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp1=new XMLHttpRequest();
        }
        else
        {// code for IE6, IE5
            xmlhttp1=new ActiveXObject("Microsoft.XMLHTTP");
        }
        xmlhttp1.onreadystatechange=function()
        {
            if (xmlhttp1.readyState==4 && xmlhttp1.status==200)
            {
                response.write(xmlhttp1.responseText);
// $('#div1').html(xmlhttp1.responseText); // you can display response in div.
            }
        }
        xmlhttp1.open("GET","IsFolderExists.asp",true);
        xmlhttp1.send();
        return false;
    }

Happy Coding!
