Hello Everyone and thanks for your help in advance. I am working on an AJAX Function that quries a database then generates the results in as fashion similar to Google Suggest. The application can be located at:

http://www.kidsmedicalcare.com/Search.aspx

However, I am running into a Javascript error "Expected ')'" but I can't seem to figure out what is throwing the error. I have traced the problem somewhat to the hyperlinks that are created with the search results, i.e. if I don't make them into hyperlinks, there is no error. However, it appears, at least to my very small Javascript knowledge, that the links are formed properly (you can view the return text in the large textbox to the right), so I really don't know what the problem is. Any help on this issue will be greatly appreciated. Thanks.

can you provide some source code for your Javascript ? also try the page in Firefox as that has a better Javascript debugger and console than IE.

Here's the code:

// This sample only supports IE6 and FireFox

var xmlHttp;
var browser = "IE";

// Check for FireFox
if(navigator.userAgent.indexOf("Firefox") != -1)
{
   browser = "FF";
}

function CaptureSearchText()
{
    // Get a reference to the SearchTextBox control and
    // extract the contents into a variable
    var searchTextBox = document.getElementById("SearchTextBox");
    var searchText = searchTextBox.value.toLowerCase();

    //alert(searchText);

    // Call the SendSearchRequest function
    SendSearchRequest(searchText);
}

function DisplaySearchResults(searchResults)
{
    // Get a reference to the ResultsPanel control and
    // render the results from the server
    var resultsPanel = document.getElementById("ResultsPanel");

    resultsPanel.innerHTML = searchResults;

    //if(searchResults != "")
    if(searchResults != "0")
    {
        // Make sure that the panel is in the proper position
        // and that it is visible
        resultsPanel.style.top = "55px";
        resultsPanel.style.visibility = "visible";
    }
    else
    {
        // The server returned no results so hide the panel
        resultsPanel.style.visibility = "hidden";
    }
}

function DisplaySelectedResult(selectedResultText)
{
    // Get references to our controls
    var searchTextBox = document.getElementById("SearchTextBox");
    var resultLabel = document.getElementById("ResultLabel");
    var resultsPanel = document.getElementById("ResultsPanel");

    // Set the contents of the textbox and label to our selected result
    searchTextBox.value = selectedResultText;
    resultLabel.innerHTML = "You selected: " + selectedResultText;

    // Hide the results panel
    resultsPanel.style.visibility = "hidden";
}

function SendSearchRequest(searchText)
{
    // Create a new XmlHttp object
    if(browser == "IE")
    {
        xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    else if(browser == "FF")
    {
        xmlHttp = new XMLHttpRequest();
    }

    // Define the request url and encode the search text
    var requestUrl = "Server.aspx?searchtext=" + encodeURIComponent(searchText);
    //var requestUrl = requestURL = "data/test.txt";
    //document.Form1.helpbox.value = requestUrl;

    // Tell XmlHttp that our request is asynchronous
    var isAsyncRequest = true;

    // If the object is successfully created then
    if(xmlHttp)
    {
        // Set the callback function
        xmlHttp.onreadystatechange = ReceiveSearchResults;
        // Send the request
        xmlHttp.open("GET", requestUrl, isAsyncRequest);
        xmlHttp.send(null);
    }
}

function ReceiveSearchResults()
{
    // Make sure the response is complete
    if(xmlHttp.readyState == 4)
    {
        // Make sure the return status from the server is OK
        if(xmlHttp.status == 200)
        {
            // Get the results from the server and call
            // the DisplaySearchResults function
            DisplaySearchResults(xmlHttp.responseText);
            document.Form1.helpbox.value = xmlHttp.responseText;
        }
        else
        {
            alert("There was a problem retrieving data from the server.");
        }
    }
}

Someof the results contain apostrophes, e.g "WEGENER'S GRANULOMATOSIS" so that the links created reads The extra single quote fouls up the JavaScript
There are a few ways to fix this. The easiest, in my opinion, is to have the service return the links like: As a side issue the lang attribute on the script element is incorrect. This refers to the natural language. You should also avoid "language" as this is now deprecated. The official way is to state the mimetype:
