I want to ajaxify my Login page written in jsp. I already wrote the "verify_login" function which return a boolean value: either true or false.
Now the point is that I dunno how to retrieve this boolean value into my ajax script. I know nothing about Ajax, I just saw this code and im trying to do the same: http://woork.blogspot.com/2007/10/lo...x-and-php.html
In the following code, the result of the login page is a value of 0 if the login fails, or the function returns the username in the other case. In my case, I wanna test: if (response == false) ... how can I do it ? it's not working
Code:
function loginReply() {
if(http.readyState == 4){
var response = http.responseText;
if(response == 0){
// if login fails
document.getElementById('login_response').innerHTML = 'Login failed! Verify user and password';
// else if login is ok show a message: "Welcome + the user name".
} else {
document.getElementById('login_response').innerHTML = 'Welcome'+response;
}
}
In my case, I wanna test: if (response == false) ... how can I do it ?
You already stated that it returns a 0 if the login fails, or the username if it passes. In this case, you will never receive a false. So why are you trying to check for it?
Are you refering to whether or not the AJAX request itself fails?

Below is the AJAX object. The code above are examples of how to reference the object properly. Put the object itself in a .js file and link to it within the <head> tag. Then to call it, you would want something similar to the following.
Code:
function postUpdate(txt){
//txt would be the returned text
if(response == 0){
document.getElementById('login_response').innerHTML = 'Login failed! Verify user and password';
}
else{
document.getElementById('login_response').innerHTML = 'Welcome' + response;
}
}
AJAX.post('login.php', 'user=' + user + '&pass=' + pass, postUpdate);
