javascript - 访问事件之外的方法

Question

我有以下代码，我试图在滑动事件中调用 this.swipe 方法，该方法会触发任何函数。问题是它不知道 this.carousel.swipe 上下文中的 this.swipe 是什么。我怎样才能触发这个功能？

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);
  }

}

Answer 1

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
})

}
