我有这个SVG动画 HERE ,现在如果看到SVG,你会看到画出虚线,绘制线条的代码如下:
$(document).ready(function() {
$("#sec-three").waypoint(function(direction) {
/* code for first line animation */
var offset = parseInt($('#move-opacity').attr("offset"));
setInterval(function() {
$('#move-opacity').attr("offset", offset + "%");
if (offset < 100) {
$('#last-opacity').attr("offset", (offset + 1) + "%");
}
offset++;
}, 25);
/* code for secound line animation */
var offset1 = parseInt($('#move-opacity-1').attr('offset'));
setInterval(function() {
$('#move-opacity-1').attr("offset", offset + "%");
if (offset < 90) {
$('#last-opacity-1').attr("offset", (offset + 1) + "%");
}
offset++;
}, 25);
$("#lock").attr( "class" , "animated bounceInUp");
$("#quote-icon").attr( "class" , "animated bounceInUp delay-05s");
}, {
offset: '75%'
});
$("#lock").addClass("animated bounceInUp");
});
现在,第一条黑色虚线的动画绘制是完美的,但第二条虚线(黄色虚线)的绘制动画不是我想要的方式,I.E。我真的很喜欢是在相反的方向绘制线条,现在首先绘制箭头,我真正想要的是动画从行尾开始,我该如何做到这一点?

您只需要反转黄色渐变的linearGradient
定义,如下面的代码块,并反转相应的jQuery代码。
<defs>
<linearGradient id="yellow-gradient">
<stop offset="100%" id="move-opacity-1" stop-opacity="0" stop-color="#ffde17" />
<stop offset="100%" id="last-opacity-1" stop-opacity="1" stop-color="#ffde17" />
</linearGradient>
</defs>
var offset1 = parseInt($('#move-opacity-1').attr('offset'));
setInterval(function() {
if (offset1 > 0) {
$('#move-opacity-1').attr("offset", offset1 + "%");
$('#last-opacity-1').attr("offset", (offset1 + 1) + "%");
}
offset1--;
}, 25);
