在MVC中,您可以使用以下视图模型:
public class MyCVViewModel
{
[Required]
[StringLength(100, ErrorMessage = "Resume Title cannot exceed 100 characters.")]
[Display(Name = "Resume Title")]
public string ResumeTitle { get; set; }
[Required]
[StringLength(1000, ErrorMessage = "Personal Statment cannot exceed 1000 characters.")]
[Display(Name = "Personal Statement")]
public string Statement { get; set; }
public List<MyCompanyViewModel> Companies { get; set; }
}
public class MyCompanyViewModel
{
[Required]
[StringLength(100, ErrorMessage = "Company Name cannot exceed 100 characters.")]
[Display(Name = "Company Name")]
public string CompanyName { get; set; }
[Required]
[StringLength(100, ErrorMessage = "Job Title cannot exceed 100 characters.")]
[Display(Name = "Job Title")]
public string JobTitle { get; set; }
[Required]
[DataType(DataType.Date)]
[Display(Name = "Start Date")]
public DateTime JobStartDate { get; set; }
[Required]
[DataType(DataType.Date)]
[Display(Name = "End Date")]
public DateTime JobEndDate { get; set; }
[Required]
[StringLength(1000, ErrorMessage = "Job Description cannot exceed 1000 characters.")]
[Display(Name = "Job Description")]
public string JobDescription { get; set; }
}
MyCVViewModel有一个MyCompanyViewModel列表,这非常简单。
我开始学习knockoutjs并尝试在knockoutjs中复制相同的视图模型。
这是我到目前为止所尝试的内容:
//company viewmodel
function Company(data) {
this.name = ko.observable(data.name);
//other stuff
}
//cv view model
function CVViewModel() {
var self = this;
self.title = ko.oberservable();
self.statement = ko.oberservalbe();
//list of company view model
self.companies = ko.observableArray();
//add company
self.addCompany = function () {
self.companies.push({
name: ""
});
};
//remove company
self.removeCompany = function (company) {
self.companies.remove(company);
};
//populate with json
$.getJSON("/Class/FillCompany", function (allData) {
var mappedTasks = $.map(allData, function (item) { return new Company(item) });
self.companies(mappedTasks);
});
};
// Activate knockout binding
ko.applyBindings(new CVViewModel());
添加和删除工作正常,但我不知道如何保存整个cv viewmodel并将其发布到asp.net mvc中的控制器。
大多数在线教程发布了子视图模型(在我的公司公司列表中)并将其发布到服务器但不发布到父视图模型(在我的情况下是cvviewmdoel)。
所以在我看来,我只能将公司发布到服务器:
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<textarea name="companies" data-bind="value: ko.toJSON(companies)"></textarea>
<button type="submit">Save</button>
}
在我的控制器中我希望有一系列公司:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index([FromJson] IEnumerable<Company> companies)
{
//save to database etc..
}
如何发布整个父视图模型,以便我的控制器看起来更像:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index(MyCVViewModel cv)
{
//save to database etc..
}
其中MyCVViewModel已包含公司列表。

通过在客户端进行一些编程,您可以完成这项工作。
首先,您可能希望节省一些时间,除非您需要使用ko.mapping
无法通过订阅者处理每个公司的内容。ko.mapping.fromJS(allData, {} self.companies)
此外,在添加新公司时,您需要将其保持为可观察状态,因此请使用:
self.companies.push(new Company(name));
您可以将整个模型标题和子项作为json对象发送,以匹配您的服务器端对象。
因此,请将您的视图模型更改为以下内容:
function viewModel()
{
var self = this;
self.title = ko.oberservable();
self.statement = ko.oberservalbe();
//list of company view model
self.companies = ko.observableArray();
//add company
self.addCompany = function () {
self.companies.push(new Company(name));
};
//remove company
self.removeCompany = function (company) {
self.companies.remove(company);
};
//populate with json
$.getJSON("/Class/FillCompany", function (allData) {
ko.mapping.fromJS(allData, {} self.companies)
});
//save
saveModel = function(){
var data = ko.mapping.toJS(self);
$ajax({
url: 'Class/SaveCompany',
type: 'POST',
contentType: 'application/json',
dataType: 'json',
data: data,
success: function (data, textStatus, jqXhr) {
//do success stuff here.
}
}
然后在提交时,将您的点击事件绑定到视图模型保存事件,它将发送一个父模型,其中所有子项都作为单个表单发布。
希望这有帮助。
