How to send 'data' to ASMX web service via AJAX POST?
提问by davey1990
I can successfully receive values from my web service so in that repect the script is working fine. However I am now trying to send data to the webservice using the 'data' field below. What i cant figure out is how to send a simple string (e.g. "test") to the web service which is what my web method expects as a parameter.
我可以成功地从我的网络服务接收值，因此脚本工作正常。但是，我现在正在尝试使用下面的“数据”字段将数据发送到网络服务。我无法弄清楚的是如何将一个简单的字符串（例如“测试”）发送到 Web 服务，这是我的 Web 方法所期望的参数。
Any help is much appreciated. For example:
任何帮助深表感谢。例如：
function setQuestion() {
$.ajax({
type: "POST",
**data: "{}",** //how do i use this to send a string??
dataType: "json",
url: "http://someURL",
contentType: "application/json; charset=utf-8",
success: onSuccess
});
}
function onSuccess(msg) {
$("#questiontxt").append(msg);
}

For asmx you need to pass a stringified version of the data object, so for example:
对于 asmx，您需要传递数据对象的字符串化版本，例如：
var data = "{param1:" + param1IsANumber +
", param2:\"" + param2IsAString + "\"}";
$.ajax({
data: data,
dataType: "json",
url: url,
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (result) {}
});
Or you can hava an object and use jquery-json
或者你可以拥有一个对象并使用jquery-json
var data = {};
data.param1 = 1;
data.param2 = "some string";
$.ajax({
data: jQuery.toJSON(data),
dataType: "json",
url: url,
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (result) {}
});
Finally, your web service class must look like:
最后，您的 Web 服务类必须如下所示：
[WebService(Namespace = "http://www.somedomainname.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class MyService : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void MyServiceCall(int param1, string param2)
{
}
}

jQuery takes the data argument and converts it into the appropriate type of request variables.
jQuery 获取数据参数并将其转换为适当类型的请求变量。
So you use something like:
所以你使用类似的东西：
data: { myParameterName: "myParameterValue", myParameterName2: "myParameterValue2" }
and jQuery does the rest of the work for you.
jQuery 会为您完成剩下的工作。
A specific example based on a comment:
基于评论的具体示例：
data: { toSend: "test" }
回答by petrov.alex
data: "{"parameterName": "test"}"
data: "{"parameterName": "test"}"
in WebService: public void GetData(string parameterName) {}
在网络服务中： public void GetData(string parameterName) {}
