Javascript regex help
I have this sample text, which is retrieved from the class name in the html element:
rich-message err-test1 erroractive rich-message err-test2 erroractive rich-message erroractive err-test1 err-test2 rich-message erroractive
I am trying to map data "test1" / "test2" in each of these examples. I am currently using the following regex which matches the word type "err-test1". I can't figure out how to limit it to only the data after the hyphen (-).
/err-(\S*)/ig
My head hurts from hitting this wall.

From what I read, your code is already working.
Regex.exec()
returns an array of results on success.
The first element of an array (index 0) returns the entire string, after which all ()
nested elements are inserted into this array.
var string = 'rich-message err-test1 erroractive';
var regex = new RegExp('err-(\S*)', 'ig');
var result = regex.exec(string);
alert(result[0]) --> returns err-test1
alert(result[1]) --> returns test1

Material after - must be in the results array. The first element is all matching text (for example, "err-test1"), and the following elements are matches from the capturing brackets (for example, "test1").
myregex = /err-(\S*)/ig;
mymatch = myregex.exec("data with matches in it");
testnum = mymatch[1];
