-2 currency-formatting reactjs
我正在为我的投资组合克隆亚马逊。React 中有这样的价格:price={37.84}。我希望价格显示如下:price={37,84}。显示的价格是 84。有没有办法将价格显示为37,84?
代码:
\n<div className="home__row">\n <Product\n id="12321341"\n title="Learning React: Modern Patterns for Developing React Apps 2nd Edition"\n price={37,84}\n rating={5}\n image="https://images-na.ssl-images-amazon.com/images/I/51Kwaw5nInL._SX379_BO1,204,203,200_.jpg"\n />\nRun Code Online (Sandbox Code Playgroud)\n产品组成:

JavaScript 代码不支持使用逗号作为小数点分隔符,因此不能在数字文字中使用逗号。但是,您可以使用区域设置功能将数字格式化为字符串,例如使用数字的toLocaleString方法:
> 37.84.toLocaleString("en-de"); // based on your profile
"37,84"

如果您确实尝试使用逗号,那么它就是逗号运算符,您最终会得到最右边的值:
> 37,84
84
