首先,我是svg的初学者,我找不到一个很好的答案来解决我在Google上的问题。我一直想做的,就是在悬停时简单地设置一个svg路径。
我已经下载并使用了snap.svg和velocity.js,所以如果你知道使用其中一个或者展位的答案,请随意。
我目前的代码和我尝试的速度:
<div class="g50">
<svg class="curtain" viewBox="0 0 180 320" preserveAspectRatio="none">
<path d="M 180,160 0,200 0,0 180,0 z"/>
</svg>
</div>
<div class="g50">
<svg class="curtain" viewBox="0 0 180 320" preserveAspectRatio="none">
<path d="M 180,200 0,160 0,0 180,0 z"/>
</svg>
</div>
JS:
$('.curtain').on('mouseenter', function(){
$(this).find('path').velocity({ 'd': "m 180,34.57627 -180,0 L 0,0 180,0 z" });
});

有两种解决方案。第一个非常简单,但如果用户快速进入和退出SVG元素,它将产生不需要的效果。从本质上讲,动画会循环太长时间;但是,如果用户随意地悬停在元素上,它就可以正常工作。
Here's a demo with that solution
另一种解决方案更加强大,可以解决用户异常快速的“悬停切换”问题。如果用户快速地进出元素,此解决方案就会停止并反转动画。这是我在任何具有速度的悬停状态下使用的。

这是使用JQuery的javascript代码
...
var svg = $('.curtain');
var path = svg.find('path'); // define svg path
path.data({animating:false}); // add data for animation queue purposes
path.hover(function() { // mouse enter
/*
if the path is in the middle of an animation, stop it immediately and reverse the animation. This prevents many unwanted animations if the user hovers in and out quickly
*/
if (path.data('animating') === true){
path.velocity("stop", true).velocity('reverse',{ duration:300});
path.data({animating:false});
} else { // begin default animation
$(this).velocity({fill: '#ffcc00'},{
duration:500,
begin: function(){
path.data({animating:true});
},
complete: function(){
path.data({animating:false});
}
});
} // end of conditional statement
}, function() { // mouse exit
/*
if the path is in the middle of an animation, stop it immediately and reverse the animation. This prevents many unwanted animations if the user hovers in and out quickly
*/
if (path.data('animating') === true){
path.velocity("stop", true).velocity('reverse',{ duration:300});
path.data({animating:false});
} else { // begin default animation
$(this).velocity({fill: '#000'},{
duration:500,
begin: function(){
path.data({animating:true});
},
complete: function(){
path.data({animating:false});
}
});
} // end of conditional statement
}); // end of hover function

如果你想为路径尺寸设置动画,我建议使用Snap.svg。 Here's a simple example using snap.svg to animate the paths.
<!--add hover state data to div-->
<div class="g50" data-path-hover="m 180,34.57627 -180,0 L 0,0 180,0 z">
<svg viewBox="0 0 180 320" preserveAspectRatio="none"><path d="M 180,160 0,218 0,0 180,0 z"/></svg>
</div>
<!--add hover state data to div-->
<div class="g50" data-path-hover="m 180,34.57627 -180,0 L 0,0 180,0 z">
<svg viewBox="0 0 180 320" preserveAspectRatio="none"><path d="M 180,160 0,218 0,0 180,0 z"/></svg>
</div>
(function() {
function init() {
var speed = 250,
easing = mina.easeinout;
[].slice.call ( document.querySelectorAll( '.g50' ) ).forEach( function( el ) {
var s = Snap( el.querySelector( 'svg' ) ),
path = s.select( 'path' ),
pathConfig = {
from : path.attr( 'd' ),
to : el.getAttribute( 'data-path-hover' )
};
el.addEventListener( 'mouseenter', function() {
path.animate( { 'path' : pathConfig.to }, speed, easing );
console.log(pathConfig.to);
} );
el.addEventListener( 'mouseleave', function() {
path.animate( { 'path' : pathConfig.from }, speed, easing );
} );
} );
}
init();
})();
