如何将serializeArray作为json传递给MVC控制器 [英] How to pass a serializeArray as json to MVC controller

问题描述

我有一个表单，我希望将其数据传递给我的控制器.这是我正在进行的jQuery调用-

I have a form whose data I want to be passed to my controller. This is the JQuery call that I am making -

    var data = $form.serializeArray();

    var options = {

        contentType: "application/json",
        url: "/Form/Save",
        data: JSON.stringify(data),
        type: "post",
        datatype: "html",
        success: function (result, xhr, status) {
            console.log(result);
        },
        error: function (xhr, status, error) {
            // redirect to error page
        }
    };

    $.ajax(options);

这就是我在控制器中收到此消息的方式-

And this is how I am recieving this in controller -

    public ActionResult Save(string paramJson)
    {
        // save paramJson

        return null;
    }

但是我在保存"操作中收到的只是paramJson = null.我也在下面尝试-

But all I am recieving in Save action is paramJson = null. I tried below as well -

数据:JSON.stringify({paramJson:data})

data: JSON.stringify({paramJson: data})

但是没有用.在这里应该做什么?

but it didn't work. What should be done here?

推荐答案

我从上述答案中得到了一些提示，并且能够提出一个对我来说非常有效的解决方案.我现在收到formname: formvalue而不是name: formname, value: formvalue格式的json.这是-

I took some hint from above answer and was able to frame a solution which works perfectly for me. I am now recieving a json in the format of formname: formvalue instead of name: formname, value: formvalue format. Here it is -

    var json = {};

    // converting to formname:formvalue format
    $.each($form.serializeArray(), function (i, field) {
        json[field.name] = field.value || '';
    });

    // stringify the parameter
    var data = { paramJson: JSON.stringify(json) };

    var options = {

        contentType: "application/json",
        url: "/Form/Save",
        data: JSON.stringify(data),
        type: "post",
        datatype: "html",
        success: function (result, xhr, status) {
            console.log(result);
        },
        error: function (xhr, status, error) {
            // redirect to error page
        }
    };

    $.ajax(options);
