每次点击时 Jquery 触发动画(问题)

Question

我需要在每次单击按钮时触发动画，而不是像下面的代码片段那样切换按钮类:

我尝试使用 addClass() 和 removeClass() 类似的方法，但它没有按预期工作，代码如下:

$(document).ready(function () {
    $("button[class*='navbar-toggler']").click(function () {
        $(this).toggleClass("my-animation")
    });
})

@keyframes my-animation {
	16.65% {
		transform: translateY(8px);
	}

	33.3% {
		transform: translateY(-6px);
	}

	49.95% {
		transform: translateY(4px);
	}

	66.6% {
		transform: translateY(-2px);
	}

	83.25% {
		transform: translateY(1px);
	}

	100% {
		transform: translateY(0);
	}
}

.my-animation {
		animation-name: my-animation;
		animation-duration: 1s;
		animation-timing-function: ease-in-out;
		animation-iteration-count: 1;
}

                        </button>

使用 setTimeout 函数删除 my-animation 类并使用

.navbar-toggler{
outline:0!important;
}

$(document).ready(function () {
    if(!$("button[class*='navbar-toggler']").hasClass('my-animation')){
    $("button[class*='navbar-toggler']").click(function () {
        $(this).addClass("my-animation");
        setTimeout(function(){  $("button[class*='navbar-toggler']").removeClass("my-animation"); }, 1000);
    });
    }
})

@keyframes my-animation {
	16.65% {
		transform: translateY(8px);
	}

	33.3% {
		transform: translateY(-6px);
	}

	49.95% {
		transform: translateY(4px);
	}

	66.6% {
		transform: translateY(-2px);
	}

	83.25% {
		transform: translateY(1px);
	}

	100% {
		transform: translateY(0);
	}
}

.my-animation {
		animation-name: my-animation;
		animation-duration: 1s;
		animation-timing-function: ease-in-out;
		animation-iteration-count: 1;
}

.navbar-toggler{
outline:0!important;
}
