Passing object to a WebMethod through jquery ajax
提问by Abijeet Patro
I am trying to pass an object to a page method defined. I'm trying to pass data to it collected from three textboxes.
我正在尝试将对象传递给定义的页面方法。我正在尝试将从三个文本框收集的数据传递给它。
Page Method
页面方法
[System.Web.Services.WebMethod]
public static string saveDataToServer(object csObj)
{
// Function Body.
}
Javascript/jQuery
Javascript/jQuery
$("#osmSendMsg").click(function () {
debugger;
var cntDetails = {
cntName : $("#osmContactName").val(),
cntEmail : $("#osmContactEmail").val(),
cntMsg : $("#osmContactMessage").val()
}
PostDataToServer(cntDetails,"Please wait...","/ContactUs.aspx/saveDataToServer","csObj");
});
PostDataToServer
发送数据到服务器
// Post data to server (ajax call).
function PostDataToServer(dataToSend, strMessagetoShow, strMethodToCall, jsonObjectName) {
debugger;
/*
dataToSend Contains the JSON Object.
submitType 1 == Normal Submit; 2 == Submit and Print.
strMessagetoShow Text that is displayed in the Please Wait Window.
*/
var tempurl = strMethodToCall;
var tempdata;
$.ajax({
url: tempurl,
type: "POST",
async: false,
dataType: "json",
data: "{" + jsonObjectName + ":" + JSON.stringify(dataToSend) + "}",
//timeout: 30000,
contentType: "application/json; charset=utf-8",
success: function (data) {
tempdata = data;
},
error: function (result) {
tempdata = null;
}
}); //end of the ajax call
return tempdata;
} //End of the post Data
Now the call is reaching the web method. No problem. I'm getting the object as well.But how do I process the object?
现在调用到达 web 方法。没问题。我也得到了这个对象。但是我该如何处理这个对象呢？
As you can see, that's what I'm getting. I also tried declaring a class and passing it as the parameter..but all it's properties are empty. If you notice the data is appearing as a key, value pair. I could convert it into a Dictionary, but I believe that's a complicated solution.
正如你所看到的，这就是我得到的。我也尝试声明一个类并将其作为参数传递......但它的所有属性都是空的。如果您注意到数据显示为键值对。我可以将它转换成字典，但我相信这是一个复杂的解决方案。
A simpler solution would be welcomed!
欢迎使用更简单的解决方案！

Your result collection is being returned in the 'data' parameter of your success method. You can simply process this parameter directly like data[0].cntName.
您的结果集合将在您的成功方法的“数据”参数中返回。您可以像 data[0].cntName 一样直接处理此参数。

As you are able to reach your webmethod, you need to modify your webmethod to read the data from the object as follows:
由于您能够访问您的 webmethod，您需要修改您的 webmethod 以从对象中读取数据，如下所示：
[System.Web.Services.WebMethod]
public static string saveDataToServer(Dictionary<string, string> csObj)
{
try
{
string Name = csObj["cntName"].ToString();
string Email = csObj["cntEmail"].ToString();
//you can read values like this and can do your operation
return "";//return your value
}
catch(Exception ex)
{
throw new Exception(Ex.Message);
}
}
