how to remove “,” from a string in javascript

Question

original string is \"a,d,k\" I want to remove all , and make it to \"adk\".

I tried code below but it doesn\'t work.

Answer 1

You aren't assigning the result of the replace method back to your variable. When you call replace, it returns a new string without modifying the old one.

For example, load this into your favorite browser:

In this case, str1 will still be "a,d,k" and str2 will be "adk".

If you want to change str1, you should be doing:

var str1 = "a,d,k";
str1 = str1.replace (/,/g, "");
