Javascript更改语言逗号和分号的逗号？

Question

我想转换点中的所有逗号，并且反之亦然。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" 

这怎么办？

Answer 1

尝试

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

它使用的replace()

Answer 2

回调函数选项试试这个：

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(",");
