遇到一个错误：
window.pathSimplifierIns = pathSimplifierIns;
pathSimplifierIns.setData(arr);//这里要求传的是一个json对象
//pathSimplifierIns.setData(JSON.stringify(arr))；//最开始我是这么传的，一直不出路径，后来鑫哥告诉我，arr本身就是对象，JSON.stringify(arr)这样就是字符串了，所以出不来路径。
console.log(JSON.stringify(arr));//我一直从这看结果，以为是一个对象，其实是字符串,只是没显示出“”才让我一直以为是个对象，注意：如果是对象console.log会显示Object[...........]
