我是淘汰赛的新手,我有点问题。我有ASP.Net MVC 4应用程序,razor视图和淘汰ViewModel。我使用web api控制器来获取数据,我无法用它初始化ko.observableArray。
获取数据的控制器功能:
public IEnumerable<TaskModel> GetTasks()
{
var tasks = new[] { new TaskModel { Name = "asd", Deadline = DateTime.Now, Id = new Guid() }, new TaskModel { Name = "asdfasdf", Deadline = DateTime.Now, Id = new Guid() } };
return tasks;
}
淘汰视图模型(调用控制器是正确的,数据变量不为空)
function TasksList() {
var self = this;
self.tasks = ko.observableArray([]);
self.load = function() {
$.ajax({
type: "GET",
url: "http://localhost:11701/api/TaskApi",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data) {
self.tasks(data);
},
error: function(error) {
alert(error.status + "<--and--> " + error.statusText);
}
});
};
}
var tasksList = new TasksList();
tasksList.load();
ko.applyBindings(tasksList);
查看
@{
ViewBag.Title = "Index";
}
@Scripts.Render("~/Scripts/jquery-1.8.3.js")
@Scripts.Render("~/Scripts/knockout-2.2.1.debug.js")
@Scripts.Render("~/Scripts/knockout.mapping-latest.debug.js")
@Scripts.Render("~/Scripts/Models/TasksList.js")
<h2>Tasks</h2>
<table>
<tr>
<th>Name
</th>
<th>Priority
</th>
<th>Deadline
</th>
<th>CreatedOn
</th>
<th></th>
</tr>
<tbody data-bind="foreach: tasks" >
<tr>
<td data-bind="text: Name"></td>
<td data-bind="text: Priority"></td>
<td data-bind="text: Deadline"></td>
<td data-bind="text: CreatedOn"></td>
</tr>
</tbody>
</table>
我尝试过ko.mapping.fromJS和ko.mapping.fromJSON但它仍然没有工作,任何想法我做错了什么?提前致谢

在我看来,您的问题是您的HTML之前有ko.applyBindings
。在页面加载后调用该代码:
$(function() {
var tasksList = new TasksList();
tasksList.load();
ko.applyBindings(tasksList);
});
或者至少将您的javascript代码移到正文末尾
