How can I replace space with another string in JavaScript?

I have this code:

var str = '                  abc';
str.replace(" ","");

First, you have spelling error:

You should do:

var str = ' abc';
str = str.replace(/ /g,"");

The /g is global modifier which will replace the specified text throughout the given string.

---

Alternatively, you can use split and join like this:

var str = ' abc';
str = str.split(" ").join("");

---

var s='anishmarokey';
s.replace('a','b');

---

try this

var str = ' abc';
str=str.replace(/ /g,"");

---

Try this in any browser url

javascript:alert('strin g'.replace(/ /g, ''));

You need to use regex, not plain strings for js string.replace

var str = ' abc'; str = str.replace(/ /g, '');

Split the string by spaces and get the second part of the split string.

var newstr = str.split(" ");
str = newstr[1];
