Question

请找到图片。我已经在下拉菜单的更改事件中编写了AJAX调用，并且在选择了必填字段后，我想将所选字段传递给控制器上的“提交”按钮，然后单击另一个AJAX调用。这是我的代码。是否可以这样做。我是新蜜蜂，如果需要更多信息，请发表评论。

Answer 1

您需要传递给data一个对象：

$.ajax(
  {
     type: "POST",
     url: "/Home/GetPermissionDatail",
     data: {Username: $("#ddlUser:selected").val()},
     contentType: "application/json; charset=utf-8",
     dataType: "json",
     ...

Answer 2

试试这个我希望这会对你有所帮助

创建复选框时将复选框提供给复选框。

<input class="Checkbox" id=Checkbox' + cnt + '  value=' + item.PermID + ',' + item.Fname + ' type=checkbox>

隐藏字段

<input type="hidden" id="hidObjects" name="hidObjects" value="0" />



 <script type="text/javascript">
        $(document).ready(function(){
           var chkuser;
            $("#ddlUser").change(function (){
                chkuser = $("#ddlUser :selected").val();
            });
            $("#Submit1").click(function (){
                var SelectedIds = GetSelectCheckboxId();
                $('#hidObjects').val(SelectedIds);
                 $.ajax({
                    type: "POST",
                    url: "/Home/SetPermissionsuser",
                    data: JSON.stringify({ Username: "' + chkuser.toString() + '" }),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (response) {
                        alert(response);
                    },
                    failure: function (response) {
                        alert(response);
                    }
                });
            });

        });
 function GetSelectCheckboxId() {
        var value = "";
        $(".checkbox:checked").each(function () {
            if (value == "")
                    value = $(this).val();
                else
                    value += "," + $(this).val();
           });
        return value;
    }
    </script>

控制器上的

   [HttpPost]
 public string YourActionName(FormCollection pFormObj)
 {
     string[] arr = pFormObj["hidObjects"].Split(',');
 }

如何通过mvc 3中的ajax将值传递给控制器
