javascript - 接触事件之外的方法

我有以下代码，我试图在swipe事件中调用触发任何功能的this.swipe方法。问题是，在this.carousel.swipe上下文中它不知道this.swipe是什么。如何触发此功能？

PM.SwipeCarousel = function (carouselSelector) {
this.carousel = $j(carouselSelector);

this.carousel.swipe({
  swipe : this.swipe
})

// method to call
this.swipe = function(event, direction, distance, duration, fingerCount, fingerData) {
   console.log(event, direction, distance, duration, fingerCount, fingerData);
  }

}

最佳答案

如建议的代码应该是

PM.SwipeCarousel = function (carouselSelector) {
this.carousel = $j(carouselSelector);

// method to call
this.swipe = function(event, direction, distance, duration, fingerCount, fingerData) {
   console.log(event, direction, distance, duration, fingerCount, fingerData);
  }

this.carousel.swipe({
  swipe : this.swipe
})

}
