如何使用AJAX和JQuery用JSON数据实现PUT调用? [英] How to implement a PUT call with JSON data using AJAX and JQuery?

问题描述

我环顾四周并尝试了许多不同的方法，但似乎无法将实际数据传递给控制器​​的功能.

I've looked around and tried many different methods, but can't seem to pass actual data to my controller's function.

这是一些代码:

        var URL = "/Timesheet/Timesheet/UpdateEntry";

        var dataObject = { 'newWeekEntry': newEntry, 'oldWeekEntry': oldEntry };

        alert(JSON.stringify(dataObject));

        $.ajax({
            url: URL,
            type: 'PUT',    
            data: JSON.stringify(dataObject),
            dataType: 'json',
            success: function(result) {
                alert("success?");
            }
        });

newEntry和oldEntry都是对象.

alert行输出以下内容(为了简洁起见，删除了一些属性):

The alert line outputs this (with some properties removed, just for brevity):

{"newWeekEntry":{"MondayHours":2,"TuesdayHours":2,"WednesdayHours":5,"ThursdayHours":5,"FridayHours":"4","SaturdayHours":0,"SundayHours":0},"oldWeekEntry":{"MondayHours":2,"TuesdayHours":2,"WednesdayHours":5,"ThursdayHours":5,"FridayHours":2,"SaturdayHours":0,"SundayHours":0}}

当我调试控制器动作("UpdateEntry")时，这两个参数都用TimesheetEntry类默认参数(0)填充.

When I debug my controller action ("UpdateEntry"), the two parameters are filled with the TimesheetEntry class default parameters (0).

我可以正确传递吗?

推荐答案

dataType属性仅在从服务器获取数据时使用.将数据发送到服务器时，应将contentType设置为application/json.

The dataType attribute is only used when you're getting data from the server. You should be setting contentType to application/json when sending data to the server.
