代码：

return ferificareArrayNote(nota.split('.'));
}else if( nota.indexOf(",") != -1 ){
ferificareArrayNote(nota.split(','));

是的，我传递了一个数字而不是字符；

As stated by @Andreas, Number.isNumber is part of ES6 so not supported by IE11
正如@Andreas 所述，Number.isNumber 是 ES6 的一部分，因此不受 IE11 支持
You can add the following polyfill to you javasript
您可以将以下 polyfill 添加到您的 javasript
Number.isInteger = Number.isInteger || function(value) {
return typeof value === "number" &&
isFinite(value) &&
Math.floor(value) === value;
};
