window.location.href在chrome中不起作用，即

Question

我試圖使用jquery重定向頁面，但無法正常工作。 我試圖使用所有的偏見：

      window.location.href = url;
      location.href = url;
      window.location = url;
      location = url;
      window.location.assign(url);

我的代碼是：

      $(document).ready(function () {
                btnsubmit = $("#btnLogin");
                btnsubmit.click(function () {
                     var uName = $("#userName").val();
                     var uPass = $("#pasWord").val();
                     var str = -1;
                     $.ajax({
                          type: "Post",
                          async: false,
                          url: "Default.aspx/userLogin",
                          data: '{"userName":"' + uName + '","userPassword":"' + uPass + '"}',
                          contentType: "application/json; charset=utf-8",
                          dataType: "json",
                          success: function (response) {
                                    str1 = response.d;
                                    str = str1;
                          },
                          failure: function (msg) {
                                    alert("Please contact your administrator");
                           }
                 });
                  redirectUser(str);
               });
               redirectUser = function (str) {
                              if (str == 0) {
                                    alert("Hello you have not yet been verified.\nPlease contact your supervisor for the same.");
    }
    else if (str == 1) {

        alert("You have been approved by your supervisor.\nBut the admin has not approved you yet.");
    }
    else if (str == 2) {
        document.write("You will be redirected to main page in 5 sec.");
        setTimeout(redirect_changePassword(), 5 * 1000);
    }
    else if (str == 3) {
        document.write("You will be redirected to main page in 5 sec.");
        setTimeout(redirect_approved(), 5 * 1000);
                }
    else if (str == 4) {
                    alert("You have been rejected by your Supervisor.\nPlease contact your supervisor for the same.");
    }
    else if (str == 5) {

        alert("You were approved by your supervisor.\nBut the admin has rejected you.\nPlease contact your supervisor for the same.")
    }
    else if (str == 6) {
        document.write("You will be redirected to main page in 5 sec.");
        setTimeout(redirect_admin(), 5 * 1000);
    }
    else if (str == 7) {
        alert("Some unkonwn error has occured.\nPlease contact your administrator.");
    }
    else if (str == 8) {
                    alert("Wrong credentials");
    }
    else if (str == 9) {
                   alert("Some unkonwn error has occured.\nPlease contact your administrator.");
    }
}

redirect_changePassword = function () {
    var nextUrl = location.protocol + '//' + location.host + '/ChangePassword.aspx';
    window.location.href = nextUrl;
}
redirect_approved = function () {
    var nextUrl = window.location.protocol + "//" + window.location.host + "/UserHome.aspx";
    //window.location.href = nextUrl;
    window.location.assign(nextUrl);
    return false;
}
redirect_admin = function () {
    var nextUrl = location.protocol + "//" + location.host + "/AdminHome.aspx";
    window.location.href = nextUrl;
}

     });

請幫助我解決問題，如果我寫了網址，然后嘗試也無法正常工作。 即使它沒有重定向到谷歌。

您可以利用javascript Promise或jQuery Deferred對象

var promise = new Promise (function (resolve, reject) {
    $.ajax({
                      type: "Post",
                      async: false,
                      url: "Default.aspx/userLogin",
                      data: '{"userName":"' + uName + '","userPassword":"' + uPass + '"}',
                      contentType: "application/json; charset=utf-8",
                      dataType: "json",
                      success: function (response) {
                                str1 = response.d;
                                str = str1;
                      },
                      failure: function (msg) {
                                alert("Please contact your administrator");
                       }
});

promise.then(function success() {
      redirectUser(str);
});

根據您的代碼，在執行Ajax之前將調用redirectUser（str）函數。 您可以將ajax中的redirectUser（str）保留下來。 因此，str將為-1。

$.ajax({
      type: "Post",
      url: "Default.aspx/userLogin",
      data: '{"userName":"' + uName + '","userPassword":"' + uPass + '"}',
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function (response) {
           str1 = response.d;
           str = str1;
       },
      failure: function (msg) {
         alert("Please contact your administrator");
      }
    }).done(function(){
        redirectUser(str);
    });

我發現了錯誤，並使用以下代碼解決了該錯誤：

      document.write("You will be redirected to main page in 5 sec.\n" + "<script>window.location.href ='http://google.com'; </script>");
        //but this was not working because you have already passed data to headers, but not the redirect code.
        setTimeout(redirect_approved(), 5 * 1000);

實際上創建了新頁面，因此頁面重定向不起作用
