问题描述
我试图使用Raphael JS图形库.我想使用应该接受一个对象的属性渐变.文档说要参考SVG规范.我在SVG中找到了渐变对象，例如
I was trying to use Raphael JS graphics library. I would like to use the attribute gradient which should accept an object. Documentation says to refer to SVG specs. I found the gradient object in SVG, for instance
<linearGradient id="myFillGrad" x1="0%" y1="100%" x2="100%" y2="0%">
<stop offset="5%" stop-color="red" />
<stop offset="95%" stop-color="blue" stop-opacity="0.5" />
</linearGradient>
但是如何在我的JavaScript中引用呢?
but how can I reference that from within my javascript?
circle.attr("gradient", "myFillGrad");
不起作用:) 预先感谢
doesn't work :) Thanks in advance
推荐答案
更新: 为最新的Raphael API进行了重写:
UPDATE: Rewritten for the latest Raphael API:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"

<html lang="en">

<script src="http://raphaeljs.com/raphael.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<script type="text/javascript" charset="utf-8">
var paper = Raphael(10, 10, 800, 600);
var circle = paper.circle(150, 150, 150);
circle.attr({
"fill": "90-#f00:5-#00f:95",
"fill-opacity": 0.5
});
</script>
</body>
</html>
在此处找到了新的attr() API的文档.
The documentation for the new attr() API is found here.
