我最近了解到，基于另一个堆栈溢出响应，Internet Explorer将不显示各个单独SVG部件的CSS3动画。如果我要选择一般的svg标签，那么它将在IE中工作，但不适用于单独的部分。
要在Internet Explorer中显示，我似乎仅为此SVG的虚线边框设置动画，但保持中心的图标固定而不是动画。
有没有办法让悬停目标区域成为整个SVG来启动边框的旋转动画但是在svg的中心禁用动画？或者我是否需要以某种方式对svg进行分层？
我正在尝试在jQuery中使用条件语句，希望能够让动画在IE中运行。
/*Pseudo-code for jQuery solution. */
$('svg').mouseover(function() {
if (!$(this).hasClass('dotted-line')) { //If it does not have the class .dotted-line
$('g').rotate({ animateTo: false}); //Then disable animation
} else if ($(this).hasClass('dotted-line')) { //If it does have .dotted-line class
$('.dotted-line').animate({ rotate: '180deg' }, 1000); //then Rotate it
}
}); *//* This does not work in IE. What is the jQuery way to do this animation to work in IE */

如果我不能这样做，我正在考虑使用GSAP。
答案 0 :(得分：1)
AFAIK使用jQuery在悬停时持续运行动画并不是那么简单。它的animate()函数用于设置从a到b的CSS值，如果你想在悬停时停止并重新启动它，并让它以相同的速度再次恢复，它会很快变得复杂。 / p>
IMO，在普通的Javascript中实现它要简单得多。
var animationRunning = false;
var pandaCirc = document.getElementById("panda-circ");
var dottedLine = document.getElementById("dotted-line");
var ellipseCircumference = 336;
var dashOffset = 0;
var dashOffsetDelta = 0.5;
pandaCirc.addEventListener("mouseenter", function() {
animationRunning = true;
requestAnimationFrame(animLoop);
});
pandaCirc.addEventListener("mouseleave", function() {
animationRunning = false;
});
function animLoop(time) {
dashOffset = (dashOffset + dashOffsetDelta) % ellipseCircumference;
dottedLine.style.strokeDashoffset = dashOffset;
if (animationRunning)
requestAnimationFrame(animLoop);

更新：处理多个动画图标
之前的解决方案是一个只支持一个图标的简化版本。
如果你需要动画几个图标，那么使用全局变量进行偏移是一个坏主意。
相反，我们应该只跟踪哪个图标是动画的，并直接从该元素的状态读取短划线偏移量。
var currentDottedLineBeingAnimated = null;
var currentAnimationFrameRequest = 0;
var dashOffsetDelta = 0.5;
// Need to use querySelectAll() to get ll the matching elements
var allIcons = document.querySelectorAll(".svgicons");
// Loop through all the matches and add mouse enter and leave event handlers
allIcons.forEach(function (icon) {
icon.addEventListener("mouseenter", function (evt) {
// Cancel any pending requestAnimationFrame() requests
cancelAnimationFrame(currentAnimationFrameRequest);
// New dotted line to be animated
currentDottedLineBeingAnimated = evt.target.querySelector(".dotted-line");
// Start the animation running by requesting an animation callback
currentAnimationFrameRequest = requestAnimationFrame(animLoop);
});
icon.addEventListener("mouseleave", function () {
// Stop animation by clearing the current amnimation element
currentDottedLineBeingAnimated = null;
});
});
function animLoop(time) {
// If nothing is being animated, don't do anything this animation step
if (!currentDottedLineBeingAnimated)
return;
// Read the element's dash offset and increment it by a little
var dashOffset = Number(currentDottedLineBeingAnimated.style.strokeDashoffset) + dashOffsetDelta;
currentDottedLineBeingAnimated.style.strokeDashoffset = dashOffset;
// Request another animation callback
currentAnimationFrameRequest = requestAnimationFrame(animLoop);
