javascript - 有时会说密码在实际有效时无效

我需要确保它以Z开头，最少8个字符并且具有*。
考虑以下功能：

function validatePassword()
{
var strPassword

//Request user enter their password then check its validity

strPassword = prompt("Please Enter A Valid Password","");

while ((strPassword.length <7) || (strPassword.indexOf('*') ==-1)  || (strPassword.charAt(0) != 'Z')) {
{
alert("Your password is invalid, \n Please try again")
strPassword = prompt("Please Enter A Valid Password","");
}

//Outcome if password is valid

alert("Your password is valid")

//End while

}
}

最佳答案

在最后一次OR检查中，您有一个双{。括号过多。

function validatePassword()
{
    var strPassword  = prompt("Please Enter A Valid Password","");
    while ((strPassword.length <7) ||
        (strPassword.indexOf('*') ==-1)  ||
        (strPassword.charAt(0) != 'Z'))
    {
        alert("Your password is invalid, \n Please try again");
        strPassword = prompt("Please Enter A Valid Password","");
    }
    alert("Your password is valid");
}
