使用 jQuery 为 boxshadow 设置动画的正确方法

Direct answer

使用Edwin Martin的100，它扩展了.animate方法，你可以简单地使用"boxShadow"的正常语法，它的每一个方面——color、x- and y-offset、blur-radius和spread-radius——都会被动画化.它包括多个阴影支持.

$(element).animate({ 
  boxShadow: "0px 0px 5px 3px hsla(100, 70%, 60%, 0.8)"
}); 

Using CSS animations instead

jQuery animates by changing the style property of DOM elements, which can cause surprises with specificity and moves style information out of your stylesheets.

I can't find browser support stats for CSS shadow animation, but you might consider using jQuery to apply an animation-based class instead of handling the animation directly. For example, you can define a box-shadow animation in your stylesheet:

@keyframes shadowPulse {
    0% {
        box-shadow: 0px 0px 10px 0px hsla(0, 0%, 0%, 1);
    }

    100% {
        box-shadow: 0px 0px 5px 0px hsla(0, 0%, 0%, 0);
    }
}

.shadow-pulse {
    animation-name: shadowPulse;
    animation-duration: 1.5s;
    animation-iteration-count: 1;
    animation-timing-function: linear;
}

然后，您可以使用本机animationend事件将动画的结尾与您在JS代码中执行的操作同步:

$(element).addClass('shadow-pulse');
$(element).on('animationend', function(){    
    $(element).removeClass('shadow-pulse');
    // do something else...
});
