Question

我有一个包含文档的锚标记，它将下载或如果它是PDF，它将显示文档。这样做效果很好，但不是我已经在我的模型中放置了一些文件对象的密码保护功能，以防止只有授权用户才能查看。所以我有一个click事件，它将显示一个模态并让用户输入密码，然后我调用.ajax命令返回true或false。但我不知道如何归还真假。

这是标记：

<a href="@link.DocumentPath" onclick="checkAuth(@link.Id); ">@link.Title</a>

这是javascript：

var checkAuth = function(id) {

    var hostname = location.hostname;
    var host = '@System.Configuration.ConfigurationManager.AppSettings["hostroot"]';
    if (hostname == "localhost")
        host = "";


    $(".modal-dialog").css({
        "left": 0,
        "top": 200,

    });

    $(".modal-body").css({
        "background-color": "darkgreen"
    })


    $(".modal-title").text("This Document is Password Protected");

    var url = host + "/Communities/CheckAuth/" + id;

    $("#inviteDialog").load(url, function () {
        $("#inviteModal").modal("show");
    })

};

然后这是视图

public ActionResult CheckAuth(int? id)
{
    var encrypted = db.CommunityDocs.Where(x=>x.Id == id).Select(x=>x.Password).SingleOrDefault();

    ViewBag.encryptedPwd = encrypted;
    return PartialView();
}

最后，这是Get

<form id="checkAuth">
    <label class="sr-only" for="teamEmailAddress">Enter Password</label>
    <input class="form-control" type="text" name="password" id="password" placeholder="Enter Password to view">
    <input class="form-control" type="hidden" name="encrypted" id="encrypted" value="@ViewBag.encryptedPwd" /><br />
    <a href="#" id="btnSubmit" class="btn btn-default">Enter</a>
</form>

<script>
    $(document).ready(function () {

        $("#btnSubmit").click(function () {
            // Host
            var hostname = location.hostname;
            var host = '@System.Configuration.ConfigurationManager.AppSettings["hostroot"]';
            if (hostname == "localhost")
                host = "";

            var formdata = $("#checkAuth").serialize();
            var encryptedPwd = $("encryptedPwd").val();
            var password = $("password").val();

            $.ajax({
                type: "GET",
                url: host + "/Communities/DeCryptPwd/",

                data: formdata,
                success: function (data) {
                    $("#inviteModal").modal("hide");
                    // window.location.href = host + "/Communities/EditCommunity/" + communityId;
                    alert(data);
                },
                error: function (errorData) { alert(errorData); }
            })
        });
    });
</script>

它将返回True或False，但我不知道如何处理以返回True或False。

DeCryptPwd方法：

 public bool DeCryptPwd(string encrypted, string password)
        {
            /* Extract the bytes */
            byte[] hashBytes = Convert.FromBase64String(encrypted);
            /* Get the salt */
            byte[] salt = new byte[16];
            Array.Copy(hashBytes, 0, salt, 0, 16);
            /* Compute the hash on the password the user entered */
            var pbkdf2 = new Rfc2898DeriveBytes(password, salt, 10000);
            byte[] hash = pbkdf2.GetBytes(20);
            /* Compare the results */
            for (int i = 0; i < 20; i++)
                if (hashBytes[i + 16] != hash[i])
                    return false;


            return true;
        }

如何在onclick事件上返回true或false
