有没有办法通过一个＆QUOT; C＃＆QUOT;反对通过AJAX控制器？ [英] Is there a way to pass a "C#" object to a controller via AJAX?

问题描述

这是很简单的传递一个字符串到通过jQuery AJAX控制器的动作，但有可能要序列化一组变量成一个对象，将其发送到控制器，并有控制其识别为一个对象？

It's simple enough to pass a string to a controller action via jQuery ajax, but is it possible to serialize a group of variables into an object, send it to the controller, and have the controller recognize it as an object?

例如：

在服务器上，你有一个类的OBJ这样：

In the server, you have a class Obj as such:

class Obj{
    string a; int b; double c;
}

和控制器，你有一种方法，它期待一个OBJ对象

And in the controller, you have a method that is expecting an Obj object

public JsonResult UpdateObj(Obj obj){
    //stuff
}

有jQuery的办法序列化一些JavaScript的VAR到一个类的OBJ，然后通过AJAX后发送到MVC控制器动作？

Is there a way in Jquery to serialize some JavaScript vars into a class Obj and then send it to an MVC controller action via an AJAX post?

推荐答案

当然，让我们假设你有一个强类型的视图：

Sure, let's suppose that you have a strongly typed view:

@model Obj

<script type="text/javascript">
    // Serialize the model into a javascript variable
    var model = @Html.Raw(Json.Encode(Model));

    // post the javascript variable back to the controller 
    $.ajax({
        url: '/home/someAction',
        type: 'POST',  
        contentType: 'application/json; charset=utf-8',
        data: JSON.serialize(model),
        success: function(result) {
            // TODO: do something with the results
        }
    });
</script>

和控制器中的动作：

public ActionResult SomeAction(Obj obj)
{
    ...
}

就在这个的OBJ此言一出，使其具有公共属性，而不是某些领域：

Just a remark about this Obj, make it have public properties instead of some fields:

public class Obj
{
    public string A { get; set; }
    public int B { get; set; }
    public double C { get; set; }
}
