javascript - 我怎样才能触发这个 :hover flip effect with jQuery?

Question

这段代码就像翻转 div 的魅力一样:

查看

<div class="flip-container" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
        <div class="front">
            FLIP ME
        </div>
        <div class="back">
            FLIP ME AGAIN
        </div>
    </div>

CSS

/* entire container, keeps perspective */
.flip-container {
        perspective: 1000;
}
        /* flip the pane when hovered */
        .flip-container:hover .flipper, .flip-container.hover .flipper {
                transform: rotateY(180deg);
        }

.flip-container, .front, .back {
        width: 320px;
        height: 480px;
}

/* flip speed goes here */
.flipper {
        transition: 0.6s;
        transform-style: preserve-3d;

        position: relative;
}

/* hide back of pane during swap */
.front, .back {
        backface-visibility: hidden;

        position: absolute;
        top: 0;
        left: 0;
}

/* front pane, placed above back */
.front {
        z-index: 2;
        /* for firefox 31 */
        transform: rotateY(0deg);
}

/* back, initially hidden pane */
.back {
        transform: rotateY(180deg);
}

但是当我将鼠标悬停在 div 上时它会翻转。我希望它只在我点击它时翻转，并且每次点击时保持翻转一次。 CSS 中似乎没有 :onclick 方法。有什么方法可以使用 jQuery 来触发上面的 CSS？

我终于想出了一个非常简单的解决方案。我所要做的就是删除 :hover 方法，然后切换类:

html

<div id="flip-container" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
        <div class="front">
            FLIP ME
        </div>
        <div class="back">
            FLIP ME AGAIN
        </div>
    </div>
</div>

CSS

#flip-container {
  width: 320px;
  height: 480px;
}

.flip-container {
        perspective: 1000;
}
        .flip-container .flipper, .flip-container .flipper {
                transform: rotateY(180deg);
        }

.flip-container, .front, .back {
        width: 320px;
        height: 480px;
}

.flipper {
        transition: 0.6s;
        transform-style: preserve-3d;
        position: relative;
}

.front, .back {
        backface-visibility: hidden;

        position: absolute;
        top: 0;
        left: 0;
}

.front {
        z-index: 2;
        /* for firefox 31 */
        transform: rotateY(0deg);
}

.back {
        transform: rotateY(180deg);
}

js

$("#flip-container").click(function() {
  $(this).toggleClass("flip-container");
});
