This snippet makes links that refer to an anchor (like "<a href="#something">...</a>") scroll softly to it.\
In this example we only do it for links that also own a data-animate attribute.

$('a[href^="#"][data-animate]').live('click', function() {
  var hash = $(this).attr('href');
  var offset = $(hash).offset();
  if (offset) {
    $('html, body').animate({ scrollTop: offset.top }, 'slow');
    location.hash = hash;
    return false;
  }
});

Note that this could basically work for any element whos...

If you manipulate the DOM with JavaScript and your page contains nested elements with position: relative, chances are Internet Explorer 7 will not properly move to the right position.

I have not found a fool-proof workaround, but these are options that have worked for me:

• Try to lose some position: relative attributes, so they do not nest. This is often impossible, though.
• Force the correct redrawing of the elements using JavaScript. Adding a bogus class ($(element).addClass('touch')) seems to suffice.
• Try to give the off...

These steps are now part of Spreewald.

Here are some useful examples how to use the attached Cucumber Timecop steps:

When the date is 2011-05-06
When the time is 2011-05-06 17:30

There is also one really awesome step that lets you travel to the past or to the future:

When /^it is (\d+|a|some) (seconds?|minutes?|hours?|days?|months?|years?) (later|earlier)$/

As you can see, you describe the *time unit amo...

Although regular expression syntax is 99% interchangeable between languages, keep this in mind:

• By default, the dot character (".") does not match a line feed (newline, line break, "\n") in any language.
• Some languages allow you to modify the behavior of a regular expression by appending a modifier to the pattern expression. E.g. /foo/i makes the pattern case-insensitive in many languages. Note however that some of these modifiers may not exist or mean entirely different things in different languages.
• Some languages have a m...

If you want to play music or sounds from a browser, your choice is to use either Flash or the new <audio> tag in HTML5. Each method has issues, but depending on your requirements you might not care about all of them.

Flash

• Works in all desktop browsers, even Internet Explorer. Does not work on iPads or iPhones.
• Requires you to embed a Flash component into your page which will later play the audio for you.
• Can play MP3s or Wave files. Cannot play OGG Vorbis audio.
• Cannot reliably seek to a given position when playing VBR-enco...

There is no way to do it. This behavior is by design. You lose.

Within an event handler, there are multiple methods to cancel event propagation, each with different semantics.

• event.preventDefault()

  Only prevents the default browser behavior for the click, i.e. going to a different url or submitting a form.

  When invoked on a touchstart event, this also prevents mouse events like click to be triggered.

• event.stopPropagation()

  Prevents the event from bubbling up the DOM.

• `event.st...

Sometimes you need to dynamically load an image and do something as soon as its loaded (when for example its size is already available).

With jQuery, this seems to work across browsers:

$('<img>')
  .attr('src', '')
  .load(function() {
    alert('fully loaded!');
  })
  .attr('src', '/the/real/image/url');

Cucumber scenarios that are tagged with @javascript so they run with Selenium are very slow. You might not want to run them every time.

In order to skip all Selenium scenarios, call Cucumber like this:

cucumber --tags ~@javascript

Note that you should still run all the scenarios, including the Selenium ones, before you push a change.

Pie sometimes does not properly redraw elements upon changes. This often happens when the change comes from somewhere further up the DOM.

Consider something like:

<ul>
  <li class="active"><div class="content">Active element</div></li>
  <li class="inactive"><div class="content">Inactive element</div></li>
</ul>

with CSS
li .content {
-webkit-box-shadow: #666 0px 2px 3px;
-moz-box-shadow: #666 0px 2px 3px;
box-shadow: #666 0px 2px 3px;
behavior: url(/PIE.htc);

If you have content inside a page that is hidden by CSS, the following will work with Selenium, but not when using the Rack::Test driver. The Selenium driver correctly only considers text that is actually visible to a user.

Then I should not see "foobear"

This is because the Rack::Test driver does not know if an element is visible, and only looks at the DOM.

Spreewald offers steps to check that an element is hidden by CSS:

Then "foo" should be hidden

You can also check that an el...
