How can I check if response.Text matches a specific String in an ajax call?

I am facing an issue where I am receiving data from a servlet in an AJAX function. Within this function, I am attempting to compare the response.Text with a certain String value, for example 'x'. However, the comparison is not working as expected. The code snippet in question is as follows:

function ajaxhandler()
{
    tableHtml = response.Text;
    if(tableHtml == 'true')
        alert("Valid Move");
    else
        alert("Invalid Move");
}

Unfortunately, when running this code, no alerts are produced.

In my servlet, I have implemented the following logic:

void myfunction(HttpServlet request, HttpServlet response)
{
    String user = (session.getAttribute("user"));
    if(user == "john")
        out.println("true");
    else
        out.println("false");
}

Answer №1

Could you kindly provide the output of

console.log(JSON.Stringify(response));
? It seems like there may be an issue with the JSON response being sent. You might want to consider implementing the following approach:

JSONObject jsonResponse = new JSONObject();
if(user.equals("john"))
    jsonObject.put ("Label", "true");
else
    jsonObject.put ("Label", "false");
out.println(jsonObject.toString());
