Codaに似たスライダーを作成する方法について、jQuery for Designersのチュートリアルに従いました。
とにかく、それは初めて機能し、1 つのことを除けば素晴らしいです。最後のパネルの位置は常に間違っているようです。私が使用しているコードは次のとおりです (ちなみに、これはローカルの WordPress インストールであるため、作業の例を示すことはできません)。
<div id="carousel">
<div class="scroll">
<div class="scrollContainer">
<p class="panel" id="slide1">Guerrilla marketing solutions that will blow your mind into a thousand million pieces and then earn you <span>shit loads of money</span>.</p>
<p class="panel" id="slide2">Guerrilla marketing solutions that will blow your mind into a thousand million pieces and then earn you <span>shit loads of money</span>.</p>
<p class="panel" id="slide3">Guerrilla marketing solutions that will blow your mind into a thousand million pieces and then earn you <span>shit loads of money</span>.</p>
<p class="panel" id="slide4">Guerrilla marketing solutions that will blow your mind into a thousand million pieces and then earn you <span>shit loads of money</span>.</p>
<p class="panel" id="slide5">Guerrilla marketing solutions that will blow your mind into a thousand million pieces and then earn you <span>shit loads of money</span>.</p>

// bind the navigation clicks to update the selected nav:
$('#carousel ul').find('a').click(selectNav);
// handle nav selection - lots of nice chaining :-)
function selectNav() {
$(this)
.parents('ul:first') // find the first UL parent
.find('a') // find all the A elements
.removeClass('selected') // remove from all
.end() // go back to all A elements
.end() // go back to 'this' element
.addClass('selected');
}
function trigger(data) {
// within the .navigation element, find the A element
// whose href ends with ID ($= is ends with)
var el = $('#carousel ul').find('a[href$="' + data.id + '"]').get(0);
// we're passing the actual element, and not the jQuery instance.
selectNav.call(el);
}
if (window.location.hash) {
trigger({ id : window.location.hash.substr(1)});
} else {
$('#carousel ul a:first').click();
}
// when the DOM is ready...
$(document).ready(function () {
var $panels = $('#carousel .scrollContainer > p');
var $container = $('#carousel .scrollContainer');
// if false, we'll float all the panels left and fix the width
// of the container
var horizontal = true;
// float the panels left if we're going horizontal
if (horizontal) {
$panels.css({
'float' : 'left',
'position' : 'relative' // IE fix to ensure overflow is hidden
});
// calculate a new width for the container (so it holds all panels)
$container.css('width', $panels[0].offsetWidth * $panels.length);
}
// collect the scroll object, at the same time apply the hidden overflow
// to remove the default scrollbars that will appear
var $scroll = $('#carousel .scroll').css('overflow', 'hidden');
// handle nav selection
function selectNav() {
$(this)
.parents('ul:first')
.find('a')
.removeClass('selected')
.end()
.end()
.addClass('selected');
}
$('#carousel ul').find('a').click(selectNav);
// go find the navigation link that has this target and select the nav
function trigger(data) {
var el = $('#carousel ul').find('a[href$="' + data.id + '"]').get(0);
selectNav.call(el);
}
if (window.location.hash) {
trigger({ id : window.location.hash.substr(1) });
} else {
$('ul a:first').click();
}
// offset is used to move to *exactly* the right place, since I'm using
// padding on my example, I need to subtract the amount of padding to
// the offset. Try removing this to get a good idea of the effect
var offset = parseInt((horizontal ?
$container.css('paddingTop') :
$container.css('paddingLeft'))
|| 0) * -1;
var scrollOptions = {
target: $scroll, // the element that has the overflow
// can be a selector which will be relative to the target
items: $panels,
navigation: 'ul a',
// selectors are NOT relative to document, i.e. make sure they're unique
// prev: 'img.left',
//next: 'img.right',
// allow the scroll effect to run both directions
axis: 'xy',
onAfter: trigger, // our final callback
offset: offset,
// duration of the sliding effect
duration: 500,
// easing - can be used with the easing plugin:
// http://gsgd.co.uk/sandbox/jquery/easing/
easing: 'swing'
};
// apply serialScroll to the slider - we chose this plugin because it
// supports// the indexed next and previous scroll along with hooking
// in to our navigation.
$('#carousel').serialScroll(scrollOptions);
// now apply localScroll to hook any other arbitrary links to trigger
// the effect
$.localScroll(scrollOptions);
// finally, if the URL has a hash, move the slider in to position,
// setting the duration to 1 because I don't want it to scroll in the
// very first page load. We don't always need this, but it ensures
// the positioning is absolutely spot on when the pages loads.
scrollOptions.duration = 1;
$.localScroll.hash(scrollOptions);
});
jQuery は、scrollTo、localScroll、および serialScroll プラグインも使用します。
どんな助けでも大歓迎です。念のため、私も使用しているCSSを次に示します。
div.scroll {
position:relative;
overflow:auto;
float:left;
width:535px;
height:135px;
}
.scrollContainer p.panel {
width:535px;
height:135px;
font-size:32px;
color:#fff;
}
#carousel p span {
color:#ffc411;
}
#carousel ul {
float:right;
text-transform:uppercase;
color:#b6b6b6;
}
#carousel li {
float:left;
margin:0 0 0 10px;
}
#carousel li a {
color:#fff;
text-decoration:none;
}
#carousel li a:hover, #carousel li a.selected {
color:#b6b6b6;
}
