How to find sibling element value using jQuery after click

I am trying to find the value of the user id and password in the lower HTML using the following jQuery code, but it does not return any value. What am I doing wrong?

<div id='mainpane'>
    <form id='login' method='post' action='#'>
        <p>User Id:<input id='userid' type='text' name='userid'></input></p>
        <p>Password:<input id='password' type='text' name='password'></input></p>
        <p><input id='submit' type='submit' name='Submit' value='Submit'></input></p>           
    </form>
    <div id="message"></div>
    <p>Not a member? <a href="user-signup.html">Signup</a></p>
</div>

Here's the jQuery code:

$(document).ready(function() {
    $('#login').delegate('input#submit','click',function(){
        alert('user id is: '+$(this).parent().parent().find('#userid').html());
        var request = $.ajax({
            type:"POST",
            url:"/login",
            data: {userid:$('#userid').text(), password:$('#password').text}
            });

        });

A warning is returned with empty data. Appreciate any pointers to what I am doing wrong.

Thanks, Kalyan.

use .val()to get input value.

var userid = $("#userid").val();
var pass   = $("#password").val();

Just do:

$.post('/login', $('#login').serialize(), function() {});

instead of your call $.ajax:), .serialize()takes all the values ​​of the input data of the form and passes them to the server, also encoded for you :)

JQuery

$(function() {
// same as document.ready
    $('#login').submit(function(event){            
    // runs whenever the form is submitted - either enter or submit button is clicked
        event.PreventDefault();
        // since the form is submitted via ajax you wil want to keep the page from changing
        alert('user id is: '+$('#userid').val());
        // no need to reach back through the DOM with .parent() use the ID its the fastest, also you get input values with .val()
        $.ajax({
            type:"POST",
            url:"/login",
            data: $('#login').serialize()
            // serialize() creates an object of all the form data based on the name attribute and values - very clean
        });
    });
});

HTML

<div id='mainpane'>
    <form id='login' method='post' action=''>
        <p>User Id:<input id='userid' type='text' name='userid'/></p>
        <p>Password:<input id='password' type='text' name='password'/></p>
        <p><input id='submit' type='submit' name='Submit' value='Submit'/></p>           
    </form>
    <div id="message"></div>
    <p>Not a member? <a href="user-signup.html">Signup</a></p>
</div>
