我正在开发这个移动应用程序，并且我将这个（https://github.com/krisrak/appframework-templates/blob/master/template-CarouselViewApp.html）作为轮播来改变页面上的内容。 http://jsfiddle.net/nafis56/qCkqb/
因此，我需要在HTML，CSS和Jquery中搞乱。不幸的是，我仍然非常环保javascript，所以我需要你的帮助。我将ID更改为Class，因为我需要在同一页面中多次调用它。在原来的模板中，我把它作为一个ID。所以我这样做是为了改变它：
更改了html上的匹配代码，将其称为Class。
<div class="panel" title="Desiree Charms" id="desiree_charms" style="overflow: hidden;"
data-appbuilder-object="page">
<div class="carousel">
<div class="carousel_page">
<h2>Desiree Charms</h2>
<p><img src="images/desiree_charms.jpg" style="width: 85%; height: 85%; display: block; margin-left: auto; margin-right: auto "
data-appbuilder-object="image" class="" title="">
</p>
</div>
<div class="carousel_page">
<h2>Page Two</h2>
<p>Text and images for Page Two goes here. Swipe to go to the
next page.</p>
</div>
</div>
<div class="carousel_dots"></div>
</div>
这也在html上。
<script>
$.ui.autoLaunch = false;
$.ui.animateHeaders = false;
$(document).ready(function(){
$.ui.launch();
});
$.ui.ready(function(){
carouselSetup();
});
function carouselSetup(){
// set size of carousel
$(".carousel").width($(".carousel").closest(".panel").width());
$(".carousel").height($(".carousel").closest(".panel").height()-25);
var options={
vertical:false, // page up/down
horizontal:true, // page left/right
pagingDiv:"carousel_dots", // div to hold the dots for paging
pagingCssName:"carousel_paging", //classname for the paging dots
pagingCssNameSelected: "carousel_paging_selected", //classname for the selected page dots
wrap:true //Creates a continuous carousel
}
var carousel = $(".carousel").carousel(options);
}
将＃更改为。在Css。
.carousel {
overflow:hidden;
margin:0 -10px;
}
.carousel_page {
overflow: auto;
-webkit-scrolling:touch;
padding:0 10px;
}
.carousel_dots {
text-align: center;
margin-left: auto;
margin-right: auto;
clear: both;
position:relative;
top:0;
z-index:200;
}
.carousel_paging {
border-radius: 10px;

background: #000;
width: 10px;
height: 10px;
display:inline-block;
}
.carousel h2 {

这是jquery（我没有改变任何东西）

现在，在我将.carousel_dots更改为#carousel_dots之前的CSS文件中。旋转木马开始工作。问题是我需要它作为一个类而不是一个ID。 我很确定问题出在jquery中，在那里的某个地方我需要将carousel_dots设置为类而不是ID，但是在哪里？
任何帮助都会有很大帮助，谢谢。
答案 0 :(得分：1)
jQuery旨在触发HTML选择器，包括元素，ID或类。在ID上触发它是非常常见的，因为正如您所识别的那样，它们会发生一次并将操作隔离到该特定项目。
我知道您已将ID更改为Class，因为您想多次使用CSS类。你可以使用Class来做到这一点。但是，为了维护jQuery逻辑，您不应该为此目的将ID更改为Class。使用ID与jQuery同步。使用Class来控制你的CSS。
很难就您所显示的案例向您提供建议，因为您没有确定初始状态以及确切的更改方式。如果你能做到这一点，我们可以具体说明你应该做出哪些改变。祝好运。
