C# 使用Ajax传递json对象的语法
我试图将这些json对象传递给代码隐藏C# 使用Ajax传递json对象的语法,c#,jquery,asp.net,json,C#,Jquery,Asp.net,Json,我试图将这些json对象传递给代码隐藏 var obj = { Name: '1', Starting: '3', Timeline: [ { StartTime: '111', GoesFor: '111' } , { StartTime: '112', GoesFor: '112'
var obj = {
Name: '1',
Starting: '3',
Timeline: [
{
StartTime: '111',
GoesFor: '111'
}
,
{
StartTime: '112',
GoesFor: '112'
}
]
};
$.ajax({
url: 'default.aspx/test',
type: 'POST',
contentType: 'application/json',
data: data,
success: function(result) {
$('#result').html(result.d);
}
});
当然,下一步是字符串化对象
var data = JSON.stringify(obj);
之后,我使用jqueryajax调用将值传递给代码隐藏
var obj = {
Name: '1',
Starting: '3',
Timeline: [
{
StartTime: '111',
GoesFor: '111'
}
,
{
StartTime: '112',
GoesFor: '112'
}
]
};
$.ajax({
url: 'default.aspx/test',
type: 'POST',
contentType: 'application/json',
data: data,
success: function(result) {
$('#result').html(result.d);
}
});
关键是我从jquery库中得到了错误
POST http://localhost:63050/default.aspx/test 500 (Internal Server Error)
当我删除obj变量并将其放入JSON.stringfy方法时,问题就解决了,如下所示
var data = JSON.stringify({
obj: {
Name: '1',
Starting: '3',
Timeline: [
{
StartTime: '111',
GoesFor: '111'
}
,
{
StartTime: '112',
GoesFor: '112'
}
]
}
});
public class MyModel
{
public string Name { get; set; }
public string Starting { get; set; }
public testing2[] Timeline { get; set; }
}
public class testing2
{
public string StartTime { get; set; }
public string GoesFor { get; set; }
}
[WebMethod]
public static string Test(MyModel obj)
{
return "Hello from test" + obj.Name + obj.Starting + obj.Timeline[0].StartTime + obj.Timeline[1].StartTime;
}
是否需要将整个对象变量传递到json.stringify函数中,而不是在函数中声明和初始化
如果你们想知道的话,我的代码是这样的
var data = JSON.stringify({
obj: {
Name: '1',
Starting: '3',
Timeline: [
{
StartTime: '111',
GoesFor: '111'
}
,
{
StartTime: '112',
GoesFor: '112'
}
]
}
});
public class MyModel
{
public string Name { get; set; }
public string Starting { get; set; }
public testing2[] Timeline { get; set; }
}
public class testing2
{
public string StartTime { get; set; }
public string GoesFor { get; set; }
}
[WebMethod]
public static string Test(MyModel obj)
{
return "Hello from test" + obj.Name + obj.Starting + obj.Timeline[0].StartTime + obj.Timeline[1].StartTime;
}
不,因为在您的示例中,您传递的是一个对象,所以您需要将JSON数据放入一个对象中,以便将其解析为一个对象。否则,您传递的只是一个变量数组 基本上,您可以这样纠正问题:
$.ajax({
url: 'default.aspx/test',
type: 'POST',
contentType: 'application/json',
data: { obj: data },
success: function(result) {
$('#result').html(result.d);
}
});
这样您就可以使用原始的stringify
