Events
Bootstrap’s carousel class exposes two events for hooking into carousel functionality.
Both events have the following additional properties:
direction : The direction in which the carousel is sliding (either “left” or “right”).
relatedTarget: The DOM element that is being slid into place as the active item.
有兩個回調方法
Event Type | Description |
---|---|
slide.bs.carousel | This event fires immediately when the slide instance method is invoked. |
slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
兩個回調方法都可以使用
$(選擇器).on('slide.bs.carousel', function (obj) {
// 當前輪播索引
var index = $(this).find('.item').index(obj.relatedTarget);
console.log("索引:" + index);
});
此方法針對bootstrap 3使用
網上的.getActiveIndex()方法,適用於bootsrap v3.0.2,如果出現無法獲取的情況可以試試我這個方法
