Demo:

    var string_cs = "89898 67646g 6585dgdf7";    var stringnum = "Jh787kk";    var case_cs = ' I ';    var substring_cs = "67646G";    var stringutil_cs = new Stringcheckutil ();    Console.log ("Isnum:" + stringutil_cs.isnum (Stringnum, "all"));//must all be integer digits (without decimal points)    Console.log ("Isnum:" + Stringutil_cs.isnum (Stringnum, "part");//contains the number    Console.log ("iscontainsstring:" + stringutil_ Cs.iscontainsstring (String_cs, Substring_cs, Case_cs));    Ignore case, whether the target string is included
