我确实从netgloo
获得了JS代码JS:
var checkitem = function() {
var $this;
$this = $("#");
if ($("#diapos .carousel-inner .item:first").hasClass("active")) {
$this.children(".left").hide();
$this.children(".right").show();
} else if ($("#diapos .carousel-inner .item:last").hasClass("active")) {
$this.children(".right").hide();
$this.children(".left").show();
} else {
$this.children(".carousel-control").show();
}
};
checkitem();
$("#diapos").on("slid.bs.carousel", "", checkitem);
HTML:
<div id="diapos" class="carousel paper2 slide" data-ride="carousel">
<!-- diapos -->
<div class="carousel-inner" role="listbox">
<div class="overlay"></div>
<div class="item active" id="first">
<img src="img/01.jpg" alt="...">
</div>
<div class="item" id="second">
<img src="img/02.jpg" alt="...">
</div>
<div class="item" id="last">
<img src="img/03.jpg" alt="...">
</div>
</div>
</div>
<a class="left carousel-control" href="#diapos" role="button" data-slide="prev"><span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span><span class="sr-only">Previous</span></a>
<a class="right carousel-control" href="#diapos" role="button" data-slide="next"><span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span><span class="sr-only">Next</span></a>
代码没有隐藏相应的控件。
文件中没有其他转盘。
顺便说一句,这篇HTML的功能是什么?:
<div class="overlay"></div>
答案 0 :(得分:1)
轮播div的id是“diapos”。所以第三行应该分配给它,因为'left'和'right'是它的直接孩子:
var checkitem = function() {
var $this;
$this = $("#diapos"); // this line needs to be changed
if ($("#diapos .carousel-inner .item:first").hasClass("active")) {
$this.children(".left").hide();
//continue as before from here
另外,你可能忘记关闭'diapos'div了!
