Need Urgent but Perfect help in jQuery and CI Integration

[eluser]Mizanur Islam Laskar[/eluser]
Hi, I'm new in CI. I need to integrate jQuery in CI (including remote script funtions for AJAX) for my current 2 projects. Can any expert help me with a proper and complete code-snippets?

For example, I need to develope an exact thing like http://www.simplypost.ca/register_step1.php, which is created from the scratch, but I need to develope it in CI now. Play with the link to know my reqirements perfectly, like type [email protected] in the Email Address field and press TAB. Again type another email like [email protected] and pess TAB....yes, remote scripts are responsible there for that unique-validity checking. Also type both correct/incorrect digits in Captcha field, type password less than 6 char, etc.

I went through the existing wikis in this site, but nothing could not give me a solution. Plz, I'm really need this very badly....Thanks
