Javascript更改逗号以获得​​逗号的积分和积分？

Question

我想用点转换字符串中的所有逗号，反之亦然。但是我不知道该怎么做，因为我在第一次更改后得到所有逗号或分数。

"1.000,20" should become "1,000.20"

如何做到这一点？

Answer 1

尝试

"1.000,20".replace(/[\.,]/g, function (m) { return m == '.' ? ',' : '.' })

使用replace()

的回调函数选项

Answer 2

试试这个：

var str = "1,000.20";

//Split into components based on a period
var components = str.split('.');

//Iterate through each component, replacing commas with periods
var length = components.length;

for (var i = 0; i < length; i++) {
   components[i] = components[i].replace(",", ".");
}

//Array.join can be slow but still useful - join with commas
str = components.join(",");
