如何序列化模型，并在ajax请求中将其传递给MVC控制器 [英] How to serialize model, pass it to MVC controller in ajax request

问题描述

我试图将我的页面模型传递给我的控制器进行处理。
处理完信息后，我想更新id为savedText的div，以显示账单信息已成功保存。

I'm trying to pass my page's model to my controller for processing. After processing the information, I want to update the div of id "savedText" to display "Billing Information saved successfully."

我的观点是这样的

function testingFunction() {
    var obj = $('testForm').serialize();

    $.ajax({
        url: '@Url.Action("TestingFunction", "BuildGiftCard")',
        dataType: 'json',
        success: function (result) {
            $("#savedText").html(result);
        },
        contentType: 'application/json; charset=utf-8',
        data: JSON.stringify(obj)
    });

    return false;
}

我在控制器中有这个：

[HttpPost]
public JsonResult TestingFunction(PurchaseModel model)
{
    return Json("Billing information saved successfully.");
}

我做错了什么？

在chrome中的检查元素时，在网络标签中，表示没有找到我的控制器方法。

When "inspecting element" in chrome, in the network tab, it's saying that my controller method isn't found.

另外，这对我很重要将整个模型从视图中获取到控制器的函数中（本例中为TestingFunction），以便我可以获取表单信息并保存它。我试着使用.serialize（）函数，但这会导致obj =（空字符串）。

Also, it's important for me to get the entire model from the view into the controller's function (TestingFunction in this case) so that I can get the form information and save it. I'm trying the .serialize() function but that results in obj = (empty string).

推荐答案

Three things:

1. $（'testForm'）应该可以是 $ （'.testForm'）或 $（'＃testForm'）。因为它正在尝试选择< testForm>< / testForm> 。


2. 如果您只是发送
   
3. 尝试做一个发布请求：

1. $('testForm') should probably be $('.testForm') or $('#testForm'). As it is you're trying to select a <testForm></testForm>.
2. If you're just sending the form, it doesn't need to be json.
3. Try doing a post request:

$.ajax({
    url: '@Url.Action("TestingFunction", "BuildGiftCard")',
    dataType: 'json',
    success: function (result) {
        $("#savedText").html(result);
    },
    data: $('#testForm').serialize(),
    type: 'POST'
});
