请问一下，Idraw对 IE10 / IE11 这类浏览器支持吗，因为我在谷歌浏览器能正常运行，但在IE11上提示错误

@SaitamaSiSi Canvas的2D绘制IE10-11是支持的 https://caniuse.com/?search=CanvasRenderingContext2D

你遇到的报错是ES6的Symbol报错，必须要引用 polyfill 解决，
你可以尝试加入 babel的polyfill https://babeljs.io/docs/en/babel-polyfill.html
或者 es5-shim https://www.npmjs.com/package/es5-shim

谢谢您的回复，我设置了polyfill后，iDraw对象能够生成，但在调用setdata的时候报调用的对象无效，后面试过addElement等也会报这个错，好像只要调idraw方法就会出现，可是iDraw对象生成的时候并没有报异常

经过测试后，发现用调试模式下运行会报这个错误，但在发布程序之后再运行就正常了，可能是我调试模式的一些设置问题吧，谢谢您的帮助
