Question

我的MVC模型中有对象列表，如下所示。

   @Html.EditorFor(model => model.LstEmploymentHistory)
   <button id="btnAddHistory" data-bind="click: addHistory">Add one</button>

我需要在加载时将它绑定到Knockout可观察数组。

<script type="text/javascript">
    //Data
    var History = function () {
        var self = this;
        self.CompanyName = ko.observable();
        self.Designation = ko.observable();
        self.StartDate = ko.observable();
        self.EndDate = ko.observable()
    };
    var viewModelEmploymentHistory = function () {
        // Operations
        var self = this;
        self.historyList = ko.observableArray([new History()]); // Put one line in by default           
        self.addHistory = function () { self.historyList.push(new History()) }
        self.removeHistory = function (history) {
            self.historyList.remove(history)


        }
        self.educationList = ko.observableArray([new Education()]); // Put one line in by default  
        self.addEducation = function () { self.educationList.push(new Education()) };
        self.removeEducation = function (education) {
            self.educationList.remove(education)

        }
    };
    //Data
    var Education = function () {
        var self = this;
        self.Degree = ko.observable();
        self.YearOfPassing = ko.observable();
        self.Percentage = ko.observable();
        self.Institute = ko.observable()

    };


    //var masterVM = (function () {
    //    this.viewModelEducationalDetails = new viewModelEducationalDetails(),

    //    this.viewModelEmploymentHistory = new viewModelEmploymentHistory();
    //})();

    //ko.applyBindings(masterVM)
    ko.applyBindings(new viewModelEmploymentHistory());

    // ko.applyBindings(new viewModelEducationalDetails(), document.getElementById("containerEducation"));
    //ko.applyBindings(new viewModelEmploymentHistory(), document.getElementById("containerHistory"));     
</script>

任何人都可以帮我解决在页面加载时将C＃列表绑定到可观察数组的问题。？

Answer 1

您需要使用JavaScript理解的格式，例如JSON.。

因此，在您的控制器中，您需要serialise the model into a JSON string

类似的东西：

related_name='profile'

然后你可以在JavaScript / MVC中使用它，有几种方法可以做到这一点。最简单的方法是将其写入输入

Model.JsonString = JsonConvert.SerializeObject(Model.LstEmploymentHistory);

然后read it in your js：

@Html.HiddenFor(h => h.JsonString);

然后turn this back into an array：

var Json = document.getElementById('JsonString').value;

然后你需要将它绑定到你的observable中。你还没有真正解释过这是怎么回事，所以我会把这个留给你......

如果在Razor中绑定，则可以使用以下内容：

var myModel = {
    LstEmploymentHistory: @Html.Raw(Json.Encode(Model.LstEmploymentHistory))
};
