我有一个jQuery Cycle幻灯片,由带有附加文本的图像组成,用作标题样式文本。图像淡入,文本(放置在div中)进出动画,大致与使用前回调方法的图像同时进行。我现在尝试添加上一个和下一个控件。它们有效,但是它们会立即前进到下一个/上一个幻灯片,因为之前的回调是延迟的,它们似乎没有触发之前的回调。我想知道如何使整个系统工作,并且如果我点击上一个和下一个控件,动画文本会与图像同时淡入。
解决此设置的最佳方法是什么?我是在正确的道路上还是有更有效率的方法来解决这个问题?代码如下,提前谢谢!
<div id="sliderCont">
<a href="#" id="prev1" name="prev1">PREV</a> <a href="#" id="next1" name=
"next1">NEXT</a>
<ul id="slider">
<li>
<a href="#"><img src="library/images/car_tarp.jpg" /></a>
<div class="captionHidden">
<div class="captionInner">
<h2 id="slide1_headline1">Unveiling a Revolution</h2>
<h3 id="slide1_headline2">in Automotive Hospitality</h3>
<h4 id="slide1_headline3">What Makes Us Different</h4>
</div>
</div>
</li>
<li>
<a href="#"><img src="library/images/passion.jpg" /></a>
<div class="captionHidden">
<div class="captionInner">
<h2 id="slide2_headline1">Providing the Blueprint For</h2>
<h3 id="slide2_headline2">Performance with<br />
Passion</h3>
</div>
</div>
</li>
</ul>
</div>
接下来,CSS
*, html, body { margin:0;padding: 0; }
#sliderCont {
height: 512px;
width:1200px;
overflow: hidden;
position: relative;
margin-top: 30px;
-webkit-box-shadow: 0 0 7px rgba(0, 0, 0, 0.35), inset 0 -1px 0 rgba(0, 0, 0, 0.2);
-moz-box-shadow: 0 0 7px rgba(0, 0, 0, 0.35), inset 0 -1px 0 rgba(0, 0, 0, 0.2);
box-shadow: 0 0 7px rgba(0, 0, 0, 0.35), inset 0 -1px 0 rgba(0, 0, 0, 0.2);
}
#slider {
width: 1200px;
height: 512px;
z-index: 1;
margin: 0;
padding: 0;
background: #ccc;
overflow: hidden;
}
#slider li {
margin: 0;
}
div.caption {
display: none;
position: absolute;
top: 60px;
left: 60px;
z-index: 2;
font-weight: lighter;
}
div.captionHidden {
display: block;
position: absolute;
top: 60px;
left: 60px;
z-index: 2;
width:1080px;
}
div.captionInner {position: relative; width:1080px;}
div.caption span.item {
display: inline-block;
padding: 10px;
font-size: 20px;
background-color: #2C2C2C;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.25), inset 0 -1px 0 rgba(0, 0, 0, 0.2);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, 0.25), inset 0 -1px 0 rgba(0, 0, 0, 0.2);
box-shadow: 0 1px 3px rgba(0, 0, 0, 0.25), inset 0 -1px 0 rgba(0, 0, 0, 0.2);
color: #E7E7E7;
}
div.caption span.item.second {
margin-left: 15px;
margin-top: -5px;
}
span.slider-highlight {
color: #59b5e2;
}
h2#slide1_headline1 { font-size: 79px;text-align: right;font-weight: normal; color: #353534;}
h3#slide1_headline2 { font-family: "Arial Black", Arial; font-size: 32px;text-align: right;font-weight: bold; color:#353534;}
h4#slide1_headline3 { font-size: 18px;text-align: right;font-weight: normal; color: #353534;}
h2#slide2_headline1 { font-family: "Arial Black", Arial;font-weight: bold; font-size: 32px;text-align:left; color: #ffffff;}
h3#slide2_headline2 { font-size: 79px;text-align: left;font-weight: normal;color:#ffffff;}
然后我们的循环jQuery:
$(function() {
$('#slider').cycle({
fx: 'fade',
speed: 800,
prev: '#prev1',
next: '#next1',
easing: 'easeOutCubic',
timeout: 5000,
before: onBefore
});
function onBefore(curr, next, opts) {
$(this).children('.captionHidden').css({
'opacity': '0',
'top': '0px'
});
$(this).children('.captionHidden').animate({
opacity: 1,
top: '60px'
}, 600, 'easeOutCubic').delay(5000).animate({
'opacity': 0,
'top': '-5px'
}, 500, 'easeOutCubic');
}
});
答案 0 :(得分:2)
我实际上是另一种方式;我将fx更改为scrollLeft,然后将动画放在after回调之后(并使用before callback'重置'标题文本div容器为opacity:0;并且top:0;
$(function() {
$('#slider').cycle({
fx : 'scrollLeft',
speed : 700,
prev: '#prev1',
next: '#next1',
easing: 'easeOutCubic',
timeout: 5000,
before : onBefore,
after: onAfter
});
function onBefore(curr,next,opts) {
$(this).children('.captionHidden').css({'opacity' : '0','top' :'0px'});
}
function onAfter(curr,next,opts) {
$(this).children('.captionHidden').animate({
opacity: 1,
top: '60px'
}, 600, 'easeOutCubic')
}
});

如果我找到了你,那么你真正需要做的就是之前或之后都没有使用任何东西。我在这里写了一个简单的例子:http://jsfiddle.net/v3VP2/22/。
