我有多张图片,文字包裹在bxslider中。我想从幻灯片中复制文本并将它们放在bxslider包装器外面的div中。按下下一张幻灯片时,它应该使用相应的文本更新div。我使用Bxslider回调函数onSlideNext尝试了以下代码,但它仍然显示第一个文本:
$slider.bxSlider({
mode: 'fade',
speed: 300,
adaptiveHeight: true,
nextSelector: '#slider-next',
prevSelector: '#slider-prev',
onSlideNext: function() {
mirrorContent();
}
});
这是功能:
function mirrorContent() {
$(".project-info-mirror").html($(".project-info").html());
}
这是HTML
<div id="page-container">
<div class="slider-container" id="slider-container">
<div id="slider">
<div class="item img">
<div class="col">
<img src="img/img1.png"></img>
<div class="project-info" style="visibility:hidden">
<h2>Titel 1</h2>
Blah blah blah blah text
</div>
</div>
</div>
</div>
<div class="item img">
<div class="col">
<img src="img/img2.png"></img>
<div class="project-info" style="visibility:hidden">
<h2>Titel 2</h2>
Some other text
</div>
</div>
</div>
</div>
<div class="item img">
<div class="col">
<img src="img/img3.png"></img>
<div class="project-info" style="visibility:hidden">
<h2>Titel 3</h2>
Some other text
</div>
</div>
</div>
</div>
</div>
</div>
<div class='content-info-mirror'></div>
</div>
非常感谢任何帮助。我是新来的。

使用eq:https://api.jquery.com/eq/
var currentSlide = 0;
function mirrorContent() {
$(".project-info-mirror").html($(".project-info").eq(currentSlide++).html());
}

您应该使用onSlideNext
回调提供的参数来返回当前元素/幻灯片。
$ slideElement:目标元素的jQuery元素
oldIndex:上一张幻灯片的元素索引(转换前)
newIndex:目标幻灯片的元素索引(在。之后) 过渡)
您可以发送该元素以将文本复制到.content-info-mirror
div,您应该使用.text()
仅抓取文本而不是.html()
,并且您的HTML
中有很多错误{1}}结构我刚刚在下面做了一个演示,看看这是否会帮助你,尝试在FULL屏幕上查看它,看看content-info-mirro
div的文字在每次下一次点击时都会发生变化
$('#slider').bxSlider({
mode: 'fade',
speed: 300,
adaptiveHeight: true,
// nextSelector: '#slider-next',
// prevSelector: '#slider-prev',
onSlideNext: function(elem, oldIndex, newIndex) {
//console.log(elem.find('img').attr('src'), oldIndex, newIndex);
mirrorContent(elem);
}
});
function mirrorContent(elem) {
$(".content-info-mirror").html($(elem).find('.project-info').text());
}
&#13;
.content-info-mirror {
background-color: #c8c8c8;
text-align: center;
font-size: 2rem;
}
