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"));//非得全部是整數數字(不帶小數點)    console.log("isNum:" + stringUtil_cs.isNum(stringNum, "part"));//包含數字    console.log("isContainsString:" + stringUtil_cs.isContainsString(string_cs, subString_cs, Case_cs));    //忽略大小寫，是否包含目標字串
