javascript - 如何在 ASP .NET 中将变量从 View 传递到 Controller

Question

我发现了与我类似的问题，但在所有这些示例中，变量都是模型的一部分。我正在尝试传递一个在 javascript 中创建的变量，它不是模型的一部分。

代码:

 $(document).ready(function () {

    var url = document.URL;
    var index = url.indexOf("?email=");
    var email;

    /* If there is an EMAIL in URL, check directory to confirm it's valid   */
    if (index > -1) {
        /* There is an email */
        email = url.substr((index + 7));
        email = email.substr(0, (email.length - 4)) + "@@mymail.ca";

        /* Check directory to see if this email exists */
        @Html.Action("CheckDirectory", "Home", new { email = ???});

    }
});

有没有办法填写???使用上面的电子邮件？

您可以在 Controller URL 中将您的值作为 GET 参数传递:

$(document).ready(function () {

  var url = document.URL;
  var index = url.indexOf("?email=");
  var email;

  /* If there is an EMAIL in URL, check directory to confirm it's valid   */
  if (index > -1) {
    /* There is an email */
    email = url.substr((index + 7));
    email = email.substr(0, (email.length - 4)) + "@@mymail.ca";

    /* Check directory to see if this email exists */
    window.location.href = '/CheckDirectory/Home?email=' + email;
  }
});
