Question

我一直在努力解决这个问题。我有以下文档路径和锚标记

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

如果＆＃34; checkAuth＆＃34;我不想处理href。函数返回false。这是＆＃34; checkAuth＆＃34;码。

var checkAuth = function(id, PasswordProtected) {
                    var result = null;
                    var hostname = location.hostname;
                    var host = '@System.Configuration.ConfigurationManager.AppSettings["hostroot"]';
                    if (hostname == "localhost")
                        host = "";
                    if (PasswordProtected == "1"){
                        var pass = prompt("This document is password protected", "");

                        var response = $.ajax({

                            type: "GET",
                            url: host + "/Communities/DeCryptPwd/",

                            data: {"id": id, "password": pass},
                            success: function (data) {
                                alert(data);
                                if (data == "True")
                                    result = true;
                                if (data == "False")
                                    result = false;

                            },
                            error: function (errorData) { alert(errorData); }
                        });
}

我只是不知道如何停止处理href上的文档并返回true ... continue进程，或者false - 停止处理。

万一你需要它，这里是＆＃34;服务器端＆＃34;由.ajax

调用的代码

public bool DeCryptPwd(int id, string password) {
    var encrypted = db.CommunityDocs.Where(x => x.Id == id).Select(x => x.Password).SingleOrDefault();

    /* 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;
}

您无法从包含异步函数的函数返回异步函数的结果。因此，您需要更改成功部分中的位置，如果不受保护，则返回true。

然而，代码目前允许他们右键单击并在新窗口中打开，无论

function checkAuth = function(theLink) {
  var id = theLink.id,
      protected = theLink.getAttribute("pass") == "1",
      href = theLink.href,
      result = null,
      hostname = location.hostname,
      host = '@System.Configuration.ConfigurationManager.AppSettings["hostroot"]';
  if (hostname == "localhost")
    host = "";
  if (protected) {
    var pass = prompt("This document is password protected", "");

    var response = $.ajax({

      type: "GET",
      url: host + "/Communities/DeCryptPwd/",

      data: {
        "id": id,
        "password": pass
      },
      success: function(data) {
        alert(data);
        if (data == "True") {
          location = href;
        }
      },
      error: function(errorData) {
        alert(errorData);
      }
    });
    return !protected; // return false if protected
  }

<a href="@link.DocumentPath" onclick="return checkAuth(this)" id="@link.Id" data-pass="@PasswordProtected">@link.Title</a>

如何让我的Ajax返回一个函数并阻止我的文档下载onclick
