如何将字符串的字符更改为不同的字符？

Question

I want to convert the space in a string into another character.

Ex:
var country = "United States"

I want the space to be "-" so:
var country = "Unites-States"

This is what I tried:

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

Using the string.replace function :

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

尝试这个

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

Answer 3

Have you considered the string replace method?

Example:

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