jquery ajax前台通过json格式往后台传数据 后台对象接到的老是null

可参考我的博客：http://quarterlifeforjava.iteye.com/blog/2024336
希望能帮到你

[code="java"]
好像ajax请求少个datatype吧

var markers = [{ "position": "128.3657142857143", "markerPosition": "7" },
{ "position": "235.1944023323615", "markerPosition": "19" },
{ "position": "42.5978231292517", "markerPosition": "-3" }];

$.ajax({
type: "POST",
url: "/webservices/PodcastService.asmx/CreateMarkers",
data: JSON.stringify({ Markers: markers }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data){alert(data);},
failure: function(errMsg) {
alert(errMsg);
}
});
[/code]

能把请求头信息截图看一下么？

我怀疑是
var data1={resContactInfo:resContactInfos1};
这一句多余了

[code="java"]$.ajax({

      url: "rc/resourceCatalogManagerAction!saveResource.action", //后台处理的地址

      type: "POST",

      contentType: "application/x-www-form-urlencod",

      data: JSON.stringify(data1),

      success:function(){

     alert("success");

      }

});[/code]

把contentType改一下就可以了

var data1={resContactInfo:resContactInfos1};
改为var data1={"resContactInfo":resContactInfos1};

在ajax中添加dataType: "json"估计就可以了。

可能是你的格式错了：

如：你参考的代码中初始数据 后面的值是双引号 而你的是单引号

var persons = [{
id: "001",
name: "zhangsan",
age: "20",
gender: true,
city: "shanghai"
},
{
id: "002",
name: "lisi",
age: "21",
gender: false,
city: "beijing"
}
];

var resContactInfos1 = [{

metadataId: '001',

orgCode:'001',

orgName: 'zhangsan',

address: '20',

        email: 'shanghai' 

    }, 

    { 

    metadataId: '002', 

    orgCode: '002', 

    orgName: 'beijing', 

    address: '21', 

    email: 'beijing' 

    } 

    ]; 

请问,后台你是如何接收的?
