javascript - 如何将字符串的字符更改为不同的字符？

Question

我想将字符串中的空格转换为另一个字符。

前任：
var country = "United States"

我希望空间是“-”所以：
var country = "Unites-States"

这是我尝试过的：

var country ="United States";
var countryArray = country.split(" ");
var newCountry = function(){
for(i=0;i<countryArray.length;i++){
    if(countryArray[i]===","){
    return countryArray[i]="-";}
}

Answer 1

使用string.replace函数：

var country = "United States";
//var newCountry = country.replace(' ', '-'); //first space only
var newCountry = country.replace(/\s+/g, '-'); //this uses regexp if there is more than just 1 space / tab character.

Answer 2

试试这个

country.replace(/ /g, ",");

Answer 3

您是否考虑过字符串替换方法？

例子：

newCountry = country.replace(" ", "-");
