在 Bootstrap 模态滑块中滑动当前轮播项目

Question

我正在尝试使用 Bootstrap 轮播和 Modal 创建一个简单的灯箱。请take a look at sample file which I have here。

我想做的是启动模态轮播作为主轮播的同一幻灯片（当前幻灯片）。从示例中可以看出，当我启动 Modal 时，它只是从第一项开始，但我需要从当前活动幻灯片开始。

你能告诉我怎么做吗？

Answer 1

这似乎行得通。

$('.bell').on('show', function() {
    var targetSlide = parseInt($('#myCarousel .active').index('#myCarousel .item'));
    $('#myCarousel2').carousel(targetSlide);
});

这会获取显示在主轮播上的当前索引。

$('#myCarousel .active').index('#myCarousel .item')

这会设置模态轮播的当前幻灯片。

$('#myCarousel2').carousel(/*Number here*/);

Here is a jsFillde 上面的代码。
