1, write 4 kinds of WebService methods
[WebService (Namespace = "http://tempuri.org/")]
[WebServiceBinding (ConformsTo = wsiprofiles.basicprofile1_1)]
[ScriptService]//enable WebService to successfully pass in the JSON parameter and return the result in JSON form
[Generatescripttype (typeof (person)]///Not necessary but recommended (if the person is nested within another complex type, it is necessary to declare)
[ToolboxItem (False)]
public class WebService1:System.Web.Services.WebService
{
///
Without any parameters
///
///
[WebMethod]
public string HelloWorld ()
{
Return "Hello World";
}
///
Incoming parameters
///
///
///
[WebMethod]
public string Hello (string name)
{
return string. Format ("Hello {0}", name);
}
///
Returns a generic list
///
///
///
[WebMethod]
Public list<int> createarray (int i)
{
list<int> list = new list<int> ();
while (i >= 0)
{
List. ADD (i--);
}
return list;
}
///
Return Complex Type
///
///
///
///
[WebMethod]
Public person Getperson (string name, int age)
{
return new Person ()
{
Name = name,
Age = Age
};
}
}
///
Complex types
///
public class Person
{
public string Name {get; set;}
public int Age {get; set;}
}
2, write JS call the above method

$ (function () {
/*
1. The URL for WebService request type is Post,webservice "[Webserviceurl]/[webmethod]"
2. ContentType Declaration as JSON
3. Data to be passed in JSON string format
4. After setting the datatype as JSON, result is directly the JSON object returned.
*/
Calling the parameterless method
$ ("#btnHelloWorld"). Click (function () {
$.ajax ({

URL: "Webservice1.asmx/hello",
Data: "{name: ' Kimogigi '}",
DataType: ' JSON ',
Success:function (Result) {

});
Returns a generic list
$ ("#btnArray"). Click (function () {

});
Return Complex Type
$ ("#btnPerson"). Click (function () {

ContentType: "Application/json",
URL: "Webservice1.asmx/getperson",
Data: "{name: ' Kimogigi ', age:26}",
