        replace = india,australia*pakistan*...

I want to replace all * with , .how can i do that with jquery or javascript

Answer 1

Like this:

result = original.replace(/\*/g, ',');

JavaScript’s String#replace function can accept either a string or a regular expression for the first argument. If it’s a string, the replacement only happens for the first match. If it’s a regular expression, it’ll be the first match or all of them if you specify the g flag (global).

The regular expression is \*, which means “match a literal *” (you need the backslash because otherwise * is special to the regular expression).
