JS Replace all replaces __JS

Answer1=answer1.replace (New RegExp ('; ', ' G '), '; '); Replace the separator in the blank with the uniform ";" (replace All, where the ' G ' parameter means replace All)

Analytical:

The first time you found the Replace () method in JavaScript is to use the Str.replace ("-", "!") directly. Only the first matching character will be replaced.
and Str.replace (/\-/g, "!") You can replace all the matching characters (G is the global flag).

So you can use the following methods:
String.Replace (/reallydo/g, replacewith);
String.Replace (New RegExp (Reallydo, ' G '), replacewith);

String: An expression containing a substring to override.
Reallydo: the substring being searched.
ReplaceWith: a substring to replace.
