Question

所以我每次用户按键时都会尝试绘制一个形状，但是我得到了奇怪的控制台错误。

paper-full.js:14632 Uncaught SyntaxError: Identifier directly after number (8:42)

at oe (paper-full.js:14632)
at ae (paper-full.js:14632)
at te (paper-full.js:14632)

我对paper.js不熟悉。我的HTML，脚本代码似乎是正确的，如果有人伸出援助之手，那将是一个很大的缓解。

Answer 1

将new Path.Circle(point, 5oo)替换为new Path.Circle(point, 500)，可行：）
