Ok, so I can login fine but when I enter false info I'm redirected to the login page, what I need is to stay on the same page and show the error message e.preventDefault();
doesn't seem to work.
$(function() {
$("#login-form").submit(function(e) {
$('.fail').hide();
$.ajax({
url:"/login",
type: "post",
data: $(this).serialize(),
error:function(){
$('.fail').show();
e.preventDefault();
},
success: function(){
document.location = '/';
}
});
return false;
});
});

Your not actually doing anything with the form, ill try commenting your code to talk you through whats happening.
I'm guessing your using PHP server side for this code.
In PHP you want to check the user credentials and then tell the browser. If the login was successful send back "y"
, and if it failed "n"
.
<script type="text/javascript">
$(function() {
$("#login-form").submit(function() {
$('.fail').hide();
$.ajax({
url:"/login",
type: "post",
data: $(this).serialize(),
error:function(){
$('.fail').show();
},
success: function(data) {
if (data == "y") {
//Login was successful. Redirect statement here?
} else {
//Failed login message here
}
}
});
return false;
});
});
</script>
Edit
Try adding this in your success function. Please let me know what you get for a successful login and a failed login.
success: function(data) {
console.log(data);
}
Edit 2
This is because your ajax call is successful, just that the login failed. This is why your success handler is called.
To sort this you'll need to see what is being returned from the server, is it nothing? In which case try:
success: function(data) {
if (data == "") {
e.preventDefault();
} else {
//Login successful, redirect user.
}
}

the success occur when URL is found and accessible.
and error occur when URL is not found.
if you want check the callback MSG you must print it in the URL page & check data in success.
like this:
<script type="text/javascript">
$(function() {
$("#login-form").submit(function() {
$('.fail').hide();
$.ajax({
url:"/login",
type: "post",
data: $(this).serialize(),
success:function(data){
if(data=="true"){
alert("success");
}else{
alert("faild")
}
}
});
return false;
});
});
</script>
in login.php
<?php
//check if for true...
echo "true";
//and if it is not true...
echo "false";
?>
the data parameter in success is a string which get back the html content of "/login"

You should add:
success: function(data){
/* Validation data here, if authentication answer is correct */
if(data == 'ok')
document.location = '/';
else
/* show error here */
}
