如下图所示，我正在使用knockout。我有多个视图模型，我正在组合并传递到控制器。问题是，当我运行应用程序时，在浏览器打开时单击F12检查错误时，我遇到了这个小问题：
未捕获范围错误：超出最大调用堆栈大小

function FullEmployeeProfile ()
{
    var EmployeeEdu = new employeeEducation();
    var EmployeeHist =  new employeeEducation();
    var EmpInfo = new employeeEducation();  

}
function employeeInfo() {
    var ei = this;

     var ei = this;
        ei.Name = ko.observable("");
        ei.ID = ko.observable("");
        ei.Gender = ko.observable("");
        ei.address = ko.observable("") ;     
    }
function employeeHistory() {
        var eh = this 

         var self = this;
        eh.CompanyName = ko.observable();
        eh.Designation = ko.observable();
        eh.StartDate = ko.observable();
        eh.EndDate = ko.observable();
}

function employeeEducation() {
    var ee = this;
        ee.Degree = ko.observable();
        ee.YearOfPassing = ko.observable();
        ee.Percentage = ko.observable();
        ee.Institute = ko.observable()

    ee.fullEmployeeDetails = new FullEmployeeProfile();
    ee.saveEmployeeDetails = function() {

        $.when(postSecureData("/api/EmployeeProfile/", ko.toJSON(ee.fullEmployeeDetails)))
        .done(function (empProfile) {
            if (response.ResponseRequired == false) {
            document.getElementById("save-empDetails-btn").innerHTML = "Saving...";
            setTimeout(function () { document.getElementById("save-empDetails-btn").innerHTML = "Save" }, 2500);
            $.msgGrowl({
                type: 'info',
                title: 'Employee information saved',

        }); }

        });
    };

}
