ng-pattern

问题 I am struggling writing a Regex for angular ng-pattern to validate a form input field.An example of the possible inputs are below Valid input: @tag1,@tag2,@tag3 @tag1, @tag2, @tag3 @tag1 Invalid Input: @tag 1 @tag 1, @tag2, @tag -3 @ta g1, @t ag2 Basically it should allow comma and comma whitespace, but not allow whitespace in between tags.
