下表也是我的Excel文件的格式

<!DOCTYPE html>

    <script src="knockout-3.4.0.js" type="text/javascript"></script>
    <script src="ViewTicketsJS.js" type="text/javascript"></script>

JS文件如下：

function AddNewTicketFunc(req, ritm, task, sDate, eDate, status, comments) {
    var self = this;
    self.req = req;
    self.ritm = ritm;
    self.task = task;

    self.status = status;

}

function AppViewModel() {
    var self = this;
    self.username = ko.observable();
    self.REQ = ko.observable();;
    self.RITM = ko.observable();
    self.TASK = ko.observable();
    self.user = ko.observable();
    self.URL = ko.observable();
    self.access = ko.observable();
    self.Description = ko.observable();



    self.AddNewTicket = ko.observableArray([/*
        new AddNewTicketFunc("1", "2", "3", "4", "5", "6", "7")*/
        ]);

    self.GetCount = function () {
        var cn = new ActiveXObject("ADODB.Connection");
        var strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:/Users/nairas2.dv/Documents/Visual Studio 2012/Projects/TaskList.xlsx;Persist Security Info=False;Extended Properties=Excel 8.0;"
        cn.Open(strConn);
        var rs = new ActiveXObject("ADODB.Recordset");
        var SQL = "select * from [TicketsTable$]";
        rs.Open(SQL, cn);
        //rs.Open(cn);
        if (rs.bof) {
            document.write('No records available for this query');
        }

        if (!rs.bof) {

            rs.MoveFirst()

                //alert(count);
               /* for (var i = 0; i != rs.fields.count; ++i) {
                    document.write(rs.fields(i).value + " | ");
                }*/

                    //this.AddNewTicket.push(new AddNewTicketFunc(rs.fields(--count).value, rs.fields(--count).value, rs.fields(--count).value, rs.fields(--count).value, rs.fields(--count).value, rs.fields(--count).value, rs.fields(--count).value));
                self.AddNewTicket.push(new AddNewTicketFunc(rs.fields(0).value, rs.fields(1).value, rs.fields(2).value, rs.fields(3).value, rs.fields(4).value, rs.fields(5).value, rs.fields(6).value));
        //self.AddNewTicket.push(new AddNewTicketFunc("1", "2", "3", "4", "5", "6", "7"));

              //  document.write("<br />");
                rs.MoveNext();
            }
        }
        rs.Close();
        cn.Close();
    }
}

ko.applyBindings(new AppViewModel());

在调试时，我在推送功能

中发现了错误

以下是输出的屏幕截图： As you can see the remaining fields are blank

问题在您定义的函数中，在您定义的函数中添加 return self; 。

 function AddNewTicketFunc(req, ritm, task, sDate, eDate, status, comments) {
    var self = this;

    self.req = req;
    self.ritm = ritm;
    self.task = task;
    self.sDate = sDate;
    self.eDate = eDate;
    self.status = status;
    self.comments = comments;

    return self;
}

尝试从Excel文件读取后在observableArray中推送项目，但不是所有数据都被推送
