js test正則批量判斷字元串是否存在

function myFunction() {
    var str = "99690001";
    var res = /^(99690001|99690002|99690003|99690004|99690005)$/.test(str);
    document.getElementById("demo").innerHTML = res;
}

str = "99690001";   //true
str = "99690005";   //true
str = "99690001w";//false
str = "996900021"; //false
str = "999690001"; //false
