Info

[ 87 ] Chapter 4 The previous screenshots shows the animation in a top-down format with the start of the animation at the top and the animation nearing the end at the bottom. As we're using the slideToggle() method, it is equally valid when running backwards too.
Sliding Animations What just happened? The underlying structures we've placed on the page are pretty straight-forward. To summarize, we basically have two tables, one of which is wrapped in a , and an outer container for the whole collection of elements. The table that is wrapped will be hidden when the basket is collapsed. We also have a link at the top of the container which will show or hide the basket contents. Our JavaScript code is divided into two main sections. In the first section, we cache some jQuery selectors that we'll use a couple of times in the code to save from selecting them one at a time, each time they are required. We also define a function that we can call whenever we need to change the value of the toggling link. The function sets the text of the link using an anonymous function which returns the new text to add. This is passed to the index of the element in the collection on which the text() method was called as the first argument and the second is the original text of the element. We don't need the first argument but we must specify it in order to access the second argument. The second part of the code is the click handler for the toggle link. It checks that the containing the first is not already being animated and if not, it calls the slideToggle() method, which will either slide the basket open or closed depending on its current state. We use the callback function to update the text of the link once the animation is complete. The: animated filter Checking whether an element is already being animated using the :animated filter is a quick and easy alternative to the stop() method in the previous example in that it only applied the animation if the element was not already animated and therefore prevented a build-up of animations. Have a go hero – doing more with slideToggle Have a go at reworking the code so that it uses the slideDown() and slideUp() methods instead of the slideToggle(). It won't make the code any more efficient, but you should get to see roughly how much code the slideToggle() method can save you. [ 88 ]
