History.js gracefully supports the HTML5 History/State APIs (pushState, replaceState, onPopState) in all browsers. For HTML4 browsers it will revert back to using the old onhashchange functionality. All major browsers are supported.
This is a simple test page to get started:
<html>
<head>
<title>Test History</title>
...
Note: state url must be provided for IE to generate a unique hash. YOu can prefix the state url with '?' ('#' does not work).

Use the .prev() function to find the previous sibling of the current element:
$(this).prev()
or
$(this).prev('.selected')

$(function() {
$('body').click(function() {

The jQuery .add methods adds elements to a set of existing jQuery object collection. For example:
$('div').add('span').add('p').each(function() {
...
To build a collection from an empty set:
$coll = $();
$('li').each(function() {
i...
Note that .add does not alter the original object, but returns a new object with the added element, so you have to use:
$coll = $coll.add(elem);
$coll.add(elem) alone does not work!
The reverse of .add is .not( elements | selector ) . Or, you can use .end() to return to the collection before you called .add() .

This example came from the jQuery validation documentation. The required rule can be used to validate a required selection box when you set the value of the first option to empty.
<!DOCTYPE HTML>

The error message is the title since no error message is specified. A more fully defined validation check would look like this:
$('#my-form').validate({

The qTip tooltip hides when mouse is off the target but on the tooltip itself. This makes it hard to click links in the tooltip - when you try to click the link, it disappears. Add the " fixed: true " flag to prevent it from disppearing:
<script type="text/javascript">
$(function() {
