Hi.

In pure JS, we can split a string using an array as separator (please see "Splitting with an array as separator" here
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split>), e.g.:

var s = 's:foo.bar';
var a = s.split(/[:\.]/);
console.log(a);
(3) ["s", "foo", "bar"]

So, is there any trick to do something like this in pure Pascal? I tried:

A := TJSString(S).split([':', '.']); // error at transpile time
A := TJSString(S).split(':', '.'); // error at transpile time
A := TJSString(S).split('/[:.]/'); // the JS got only a static string

Since the TJSString.split() signature allows only a static string as first parameter, calls like those above don't work at all, then as workaround I solved it using an asm block, however, it would be nice to allow pure Pascal in that.

Thanks in advance for any help!

Hm.
The documentation text does not mention the possibility of an array, so I didn't add that. I have added an overload.

Indeed, sometimes the MDN web docs lacks information on top and are present only on bottom (examples area).

Thank you for solving! (y)

Oops, I forgot to send a patch. ^^'

Could you apply this one in attachment? The String.prototype.split() (and many other string functions) allows to pass as *separator*(*) the most powerful feature also presente in JS: regular expressions. After applying the patch, it allows:

uses JS, Web;
var
  S: string;
  A: TStringDynArray;
begin
  S := 's:foo.bar';
  A := TJSString(S).split(TJSRegexp.New('[:.]'));
  console.log(A);
end.

Result:

(3) ["s", "foo", "bar"]

The equivalent version in pure JS (notice the regex part as parameter):

var s = 's:foo.bar';
var a = s.split(/[:\.]/);
console.log(a);

Result:

(3) ["s", "foo", "bar"]

Thank you again!

(*) Snip from MDN
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split> :

*"... Separator*
*Specifies the string which denotes the points at which each split should occur. The separator is treated as a string or as a regular expression."*
