Svg 拉斐尔改变动画方向
通过使用rapheal,我成功地沿路径制作了动画,但我无法反转动画方向,,,只是如何在单击同一路径时将动画设置为另一个方向Svg 拉斐尔改变动画方向,svg,raphael,Svg,Raphael,通过使用rapheal,我成功地沿路径制作了动画,但我无法反转动画方向,,,只是如何在单击同一路径时将动画设置为另一个方向 var paper = Raphael(0,0,1024,768); var pathOne = paper.path(['M', 15,15 , 100,75]).attr({'stroke-width':18}).data("id",1); //and this is just the circle var circle = paper.circle(0, 0,

var circle = paper.circle(0, 0, 13).attr({
fill: '#09c', cursor: 'pointer'
});
//make the path as custom attribute so it can ba accessed
function pathPicker(thatPath){
paper.customAttributes.pathFactor = function(distance) {
var point = thatPath.getPointAtLength(distance * thatPath.getTotalLength());
var dx = point.x,
dy = point.y;
return {
transform: ['t', dx, dy]
};
}
}
//initialize for first move
pathPicker(pathOne);
circle.attr({pathFactor: 0}); // Reset
//Asign first path and first move
function firstMove(){
circle.animate({pathFactor: 1}, 1000});
}
pathOne.click(function(){
firstMove();
});
我无法运行原始版本,所以这里有一些使用主位的东西应该适合 没什么大不了的,获取路径的长度,迭代长度,在路径上绘制对象。它使用Raphael自定义属性来设置动画。我添加了一个自定义切换,以便于在它们之间切换 这些是关键的变化
var len = pathOne.getTotalLength();
paper.customAttributes.along = function (v) {
var point = pathOne.getPointAtLength(v * len);
return {
transform: "t" + [point.x, point.y] + "r" + point.alpha
};
};
circle.attr({ along: 0 });
function animateThere( val ) {
val = +!val; // toggle
pathOne.click( function() { animateThere( val ) } );
circle.animate({ along: val }, 2000 );
};
pathOne.click( function() { animateThere(0) } );
为了完整性,您可能需要做一些额外的检查,如仅在动画完成时允许单击或其他操作,因为如果您快速单击大量动画并缓冲动画,则可能会出现问题。您能否让它在JSFIDLE上工作,因为它不运行。我更新了代码,现在应该可以工作了。谢天谢地,它确实有效,而且非常简单。。。非常感谢
