是否有可能使用Raphael在页面周围拖放对象,而不仅仅是圆圈和矩形?
我想添加路径和图像,然后你可以到处移动,但它证明是棘手的。我想和拉斐尔一起解决这个问题,因为它支持触摸界面。
以下是代码
<script>
window.onload = function () {
var R = Raphael(0, 0, "100%", "100%"),
r = R.circle(100, 100, 50).attr({fill: "hsb(0, 1, 1)", stroke: "none", opacity: .5}),
g = R.circle(210, 100, 50).attr({fill: "hsb(.3, 1, 1)", stroke: "none", opacity: .5}),
b = R.circle(320, 100, 50).attr({fill: "hsb(.6, 1, 1)", stroke: "#fff", "fill-opacity": 0, "stroke-width": 0.8, opacity: .5}),
p = R.path("M 250 250 l 0 -50 l -50 0 l 0 -50 l -50 0 l 0 50 l -50 0 l 0 50 z") .attr({fill: "hsb(.8, 1, 1)", stroke: "none", opacity: .5});
var start = function () {
this.ox = this.attr("cx");
this.oy = this.attr("cy");
this.animate({r: 70, opacity: .25}, 500, ">");
},
move = function (dx, dy) {
this.attr({cx: this.ox + dx, cy: this.oy + dy});
},
up = function () {
this.animate({r: 50, opacity: .5}, 500, ">");
};
R.set(r, g, b, p).drag(move, start, up);
};
</script>

这里的关键(我找到的)是将x和y增量转换为转换值,path对象可以理解这些值。

有效地使用相同的方法:
var paper = Raphael(10, 50, 320, 200);
var tri = paper.path("M0 0L0 20L25 10L0 0Z").attr("fill", "#ff0");
var rex = paper.rect(10, 20, 50, 50).attr("fill", "#ff0");
var start = function () {
this.odx = 0;
this.ody = 0;
this.animate({"fill-opacity": 0.2}, 500);
},
move = function (dx, dy) {
this.translate(dx - this.odx, dy - this.ody);
this.odx = dx;
this.ody = dy;
},
up = function () {
this.animate({"fill-opacity": 1}, 500);
};
tri.drag(move, start, up);
rex.drag(move, start, up);

当翻译在拉斐尔中被弃用时,我已经修改了Nathan的答案以使用transform:
var paper = Raphael(10, 50, 320, 200);
var tri = paper.path("M0 0L0 20L25 10L0 0Z").attr("fill", "#ff0");
var start = function () {
this.lastdx ? this.odx += this.lastdx : this.odx = 0;
this.lastdy ? this.ody += this.lastdy : this.ody = 0;
this.animate({"fill-opacity": 0.2}, 500);
},
move = function (dx, dy) {
this.transform("T"+(dx+this.odx)+","+(dy+this.ody));
this.lastdx = dx;
this.lastdy = dy;
},
up = function () {
this.animate({"fill-opacity": 1}, 500);
};
tri.drag(move, start, up);
对于拉斐尔来说,我是一个相对较新的人,我是通过反复试验才想到这一点的,所以外面的人可能会解释为什么它是有效的,或者是一种更干净的方式;)

对于非圆,请尝试此方法。我认为Circle属性不同于图像、文本等。
var start = function () {
this.ox = this.attr("x");
this.oy = this.attr("y");
this.animate({r: 70, opacity: .25}, 500, ">");
},
move = function (dx, dy) {
this.attr({x: this.ox + dx, y: this.oy + dy});
},
up = function () {
this.animate({r: 50, opacity: .5}, 500, ">");
};
