提交时找不到MVC JS成员

Question

我在从JS进行验证后尝试提交表单，我在.submit行的开发者模式成员Not Found中收到错误。

这是我宣布表格的方式：

@using (Html.BeginForm(null, null, FormMethod.Post, new { id = "spc_form" }))
@Html.AntiForgeryToken()

这是代码：

<input type="button" value="Submit" class="btn btn-warning" id="submit" /> 
<input type="button" value="Save" class="btn btn-warning" id="save" />




    $('#save').click(function () {
        var validated = 1;
        //input black borders here

        if ($('#multi_project_name_0').val() == "" || $('#multi_project_name_0').val() == " ") {
            $('#multi_project_name_0').css("border-color", "red");
            validated = 0;
        }
        var x = document.getElementById("multi_pj_class").getElementsByTagName("tr").length;

        if (validated == 1) {
            if (document.getElementById("multi_sop").value == "" || document.getElementById("multi_sop").value == " ") {
                document.getElementById("multi_sop").value = document.getElementById("this_date").value;
            }
            if (document.getElementById("multi_start_pj").value == "" || document.getElementById("multi_start_pj").value == " ") {
                document.getElementById("multi_start_pj").value = document.getElementById("this_date").value;
            }
            if (document.getElementById("multi_date_evaluation").value == "" || document.getElementById("multi_date_evaluation").value == " ") {
                document.getElementById("multi_date_evaluation").value = document.getElementById("this_date").value;
            }
            for (var i = 1; i < x - 1; i++) {
                if (document.getElementById("multi_sop_" + i).value == "" || document.getElementById("multi_sop_" + i).value == " ") {
                    document.getElementById("multi_sop_" + i).value = document.getElementById("this_date").value;
                }
                if (document.getElementById("multi_start_pj_" + i).value == "" || document.getElementById("multi_start_pj_" + i).value == " ") {
                    document.getElementById("multi_start_pj_" + i).value = document.getElementById("this_date").value;
                }
            }
            document.getElementById("active").value = "2";
            document.getElementById("spc_form").submit(); <------ THIS IS WHERE THE PROBLEM IS
        }
        else {
            alert("You must complete the first Project Name field in order to save the project.");
            topFunction();
        }
    });
</script>
