为什么 clearInterval 不清除我的 setInterval function？ [等候接听]

Question

So i call a navigateRight function every 3 seconds.

WrappingCarousel.prototype.startSlideShow = function() {
        var self = this;
        clearInterval(this.slideShowInterval);
        this.slideShowInterval = setInterval(function () {
            self.navigateRight(true);
        }, 3000);
    };


WrappingCarousel.prototype.navigateRight = function(notRestart) {
    if ($("#catalog").hasClass("screen0") && $("#catalog-content").is(":visible")) {
        clearInterval(this.startSlideShow); // -----> I CLEAR IT HERE.
    }
    if (this.index+1 >= this.items.length) { this.index = -1; }
    if (!notRestart) this.startSlideShow();
    return Carousel.prototype.navigateRight.call(this);
};

Inside function which calls every 3 seconds i have an condition, which should clear this interval, but it doesn't clear it at all.

Answer 1

Please, try with clearInterval(this.slideShowInterval) inside the navigateRight function, which seems to be the right variable you used to store the value returned by the setInterval function, instead of clearInterval(this.startSlideShow) .
