javascript - Literal dollar sign in a regular expression -

-

i working canada (fr-ca) locale , trying following:

var str = "<dataset >{1}</dataset>"; var temp = "<set cost x = '1,8m $' />";  str = str.replace(/\{1\}/g, temp);

output: 

"<dataset ><set cost x = '1,8m  </dataset>" /></dataset>"

desired output: 

"<dataset ><set cost x = '1,8m $'" /></dataset>"

replace function misunderstanding $' '1,8m $' expression , hence
repeating in output. ideas/workaround? thank time.

$' has special meaning in replacement string when using js regular expressions: inserts portion of string follows matched substring. literal dollar sign in replacement string, use $$.

see https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/string/replace.
