            $('form').submit(function(){
                alert("thanks");
                return true;

            alert('else3');         
        }

    });
});


</script>

This is my Html code

<form action="" method="post" name="loginform">
<table>
<tr>
    <th>LOGIN PAGE</th>
</tr>
<tr>
    <td>Name</td>
    <td><input type="text" name="uname" id="uname" /></td>
<tr>
<tr>
    <td>Password</td>
    <td><input type="password" name="pwd" id="pwd" /></td>
<tr>
<tr>
    <td colspan="2"><input type="submit" name="submit" id="submit" value="SUBMIT" />     </td>
<tr>
</table>
</form>

Thanks in advance..

Answer 1

Instead of

$('form').submit(function(){
    alert("thanks");
    return true;
}); 

in your else, just return true;

same in your if, you don't need to

$('form').submit(function(){
    //e.preventDefault();
    return false;
});

just return true;

What you're doing in your code is hooking up to the submit event of the form. If you return false or true from submit button, it'll submit the form or not.
