无法将 JSON（从 WCFRest 返回）绑定到 HTML table

Question

我创建了一个 WCFRestful 服务，它以以下格式填充 JSON 数据

{"GetEmployeesJSONResult":"[{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000}]"}

我正在尝试使用 Knockout 在 HTML table 中显示此数据，但到目前为止未能成功。但是，硬编码值可以正确显示。

HTML 和淘汰赛

var HomeModel = function () {
        this.rows = ko.observableArray();
    };

    $(document).ready(function () {            

        $.ajax({
            method: "POST",
            url: 'http://localhost:1249/Service1.svc/GetJsonAll',
            contentType: "application/javascript",
            dataType: "jsonp",
            success: function (data) {                    
                //for (var x in data) {
                //    model.rows.push(data[x]);
                //}
                //model.rows(data);
                //console.log(model.rows);
                //var res = [{
                //    "Id": "1",
                //    "Name": "Mike",
                //    "Start_Date": "Sun 01/06/08",
                //    "Finish_Date": "Sun 01/06/08",
                //    "Salary": "Trainee"

                //}, {
                //    "Id": "2",
                //    "Name": "Jhon",
                //    "Start_Date": "Sun 01/06/08",
                //    "Finish_Date": "Sun 01/06/08",
                //    "Salary": "Trainee"
                //}, {
                //    "Id": "2",
                //    "Name": "Jhon",
                //    "Start_Date": "Sun 01/06/08",
                //    "Finish_Date": "Sun 01/06/08",
                //    "Salary": "Trainee"
                //}];
                console.log(data);
                var model = new HomeModel();
                //ko.applyBindings(model);
                ko.applyBindings({
                    rows: data.GetEmployeesJSONResult
                });
            }
        });
    });


<table>
        <thead>
            <tr>
                <th>Employee ID</th>
                <th>Name</th>
                <th>Salary</th>
            </tr>
        </thead>
        <tbody data-bind="foreach: rows">
            <tr>
                <!--<td data-bind="text: Id"></td>
                <td data-bind="text: Name"></td>
                <td data-bind="text: Salary"></td>-->
                <td>
                    <pre data-bind="text: JSON.stringify(ko.toJS($data))"></pre>
                </td>
                <td>
                    <pre data-bind="text: JSON.stringify(ko.toJS($data), null, 2)"></pre>
                </td>
                <td>
                    <pre data-bind="text: JSON.stringify(ko.toJS($data), null, 2)"></pre>
                </td>
            </tr>
        </tbody>
    </table>

有人可以帮助我吗？我卡得很厉害。

Answer 1

瞎猜，你试过吗

var HomeModel = function () {
        this.rows = ko.observableArray();
};

在$(document).ready(function () { };里面？您是否试图在它们进入 DOM 之前获取这些值？

勾选Plunker

var data = {"GetEmployeesJSONResult":"[{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000},{\"Name\":\"Sumanth\",\"Id\":101,\"Salary\":5000}]"}

var HomeModel = function () {
        this.rows = ko.observableArray();
    };

  ko.applyBindings({
                    rows: JSON.parse(data.GetEmployeesJSONResult)
                });
