我使用数据值作为对象文字,而不是按照this answer
中的说明连接字符串我的代码如下:
$.ajax({
url: "../Member/Home.aspx/SaveClient",
type: "POST",
async: false,
dataType: 'json',
contentType: 'application/json; charset=utf-8',
data: {
"projectSoid": ProjectId,
"startDate": StartDate,
"endDate": EndDate,
"clientManager": ClientManager
},
success: function(response) {
if (response.d != "") {
}
},
error: function(response) {
var r = jQuery.parseJSON(response.responseText);
alert("Message: " + r.Message);
alert("StackTrace: " + r.StackTrace);
alert("ExceptionType: " + r.ExceptionType);
}
})
我的网络方法是这样的:
[WebMethod]
public static string SaveClient(string projectSoid, string startDate,
string endDate, string clientManager)
{
...
}
但是我收到以下错误:
消息:无效的JSON原语:projectSoid
答案 0 :(得分:39)
使用您的contentType: 'application/json; charset=utf-8'
声明您将发送JSON,但目前您的data
媒体资源未持有JSON。
您需要使用data
方法将JSON.stringify
转换为JSON:
所以将您的data
属性更改为:
data: JSON.stringify({
"projectSoid": ProjectId,
"startDate": StartDate,
"endDate": EndDate,
"clientManager": ClientManager
}),
您应该注意,旧版浏览器本身不支持JSON.stringify
方法,因此您可能需要提供使用以下各种库之一的实现:

客户端的Javascript
var items = [{ projectSoid: ProjectId, startDate: StartDate, endDate: EndDate, clientManager: ClientManager }];
$.ajax({
url: '"../Member/Home.aspx/SaveClient',
type: "POST",
data: JSON.stringify({ items: items }),
//data: JSON.stringify("{DocKey : '" + DocKey + "',highlightText: '" + JSON.stringify(text) + "',pageNo: '" + pgNo + "',left: '" + left + "',top: '" + top + "',width: '" + width + "',height: '" + height + "'}"),
//data: "{DocKey\":\""+ DocKey+"\",\"highlightText\":\""+ text +"\",\"pageNo\":\""+pgNo+"\",\"left\":\""+left+"\",\"top\":\""+top+",\"width\":\""+width+"\",\"height\":\""+ height +"}}",
// data: "{DocKey : '" + DocKey + "',highlightText: '" + text + "',pageNo: '" + pgNo + "',left: '" + left + "',top: '" + top + "',width: '" + width + "',height: '" + height + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
beforeSend: function () {
alert("Start!!! ");
},
success: function (data) {
alert("Save data Successfully");
},
failure: function (msg) { alert("Sorry!!! "); evt.obj.deleteObject(); },
async: false
});
代码隐藏的网络方法
[WebMethod]
public static string SaveClient(object items) {
List<object> lstItems = new JavaScriptSerializer().ConvertToType<List<object>>(items);
Dictionary<string, object> dic = (Dictionary<string, object>)lstItems[0];
}
