javascript - Replace " ." with "." to eliminate spaces before dots

Question

I've tried with replace(/ ./g, '.'); to eliminate the comma before the dot without succes. Any idea what is wrong? Thanks.

Answer 1

I presume your complaint is that every character followed by a space is being replaced with a .. This is because . is a wildcard character. Literally, it means "match anything except a newline":

(The dot, the decimal point) matches any single character except the newline characters: \n \r \u2028 or \u2029. (MDN)

You need to escape it if you want to match a literal .:

replace(/ \./g, '.')
