在使用wxCanvas的add方法后，在另一个函数里使用this.setData就会有这个报错：

VM3735:1 jsEnginScriptError
Converting circular structure to JSON
TypeError: Converting circular structure to JSON

小程序里出现的

实测应该是浏览器内核问题，在小程序官方ide里面的chrome内核下出现问题。但是在真机上跑就ok

我只要用到 this.wxCanvas = new wxDraw(context, 0, 0, '400', '300') 就会收到同样的错误，并且该错误影响后续一些 js 的执行，且所有 shape 都无法拖动

找到问题所在了，在使用的时候我把所有的shape都放进了一个data里面的数组，只要把数组放到外面去直接用而不是this.setdata用就OK

我把wxCanvas从data挪到外面就行了
