1、編寫4種WebService方法
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService] //令WebService成功傳入Json參數，并以Json形式返回結果
[GenerateScriptType(typeof(Person))] //不是必要，但推薦添加(如果Person里面再嵌套另一個復雜類型，則必要聲明)
[ToolboxItem(false)]
public class WebService1 : System.Web.Services.WebService
{
///
/// 無任何參數
///
///
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
///
/// 傳入參數
///
///
///
[WebMethod]
public string Hello(string name)
{
return string.Format("Hello {0}", name);
}
///
/// 返回泛型列表
///
///
///
[WebMethod]
public List<int> CreateArray(int i)
{
List<int> list = new List<int>();
while (i >= 0)
{
list.Add(i--);
}
return list;
}
///
/// 返回復雜類型
///
///
///
///
[WebMethod]
public Person GetPerson(string name, int age)
{
return new Person()
{
Name = name,
Age = age
};
}
}
///
/// 復雜類型
///
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
}
2、編寫js調用以上方法
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>
DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>無標題頁title>
<style type="text/css">
input
{
width:200px;
}
<style>
<script type="text/javascript" src="jquery-1[1].2.6.min.js"></script>
<script type="text/javascript">
$(function(){
/*
1、WebService請求類型都為Post，WebService的Url為“[WebServiceUrl]/[WebMethod]”
2、contentType聲明為Json
3、data要用Json的字符串格式傳入
4、設置了dataType為json后，result就直接為返回的Json對象。
*/
//調用無參數方法
$("#btnHelloWorld").click(function(){
$.ajax({
type: "POST",
contentType:"application/json",
url:"WebService1.asmx/HelloWorld",
data:"{}",
dataType:'json',
success:function(result){
alert(result.d);
}
});
});
//傳入1個參數
$("#btnHello").click(function(){
$.ajax({
type: "POST",
contentType:"application/json",
url:"WebService1.asmx/Hello",
data:"{name:'KiMoGiGi'}",
dataType:'json',
success:function(result){
alert(result.d);
}
});
});
//返回泛型列表
$("#btnArray").click(function(){
$.ajax({
type: "POST",
contentType:"application/json",
url:"WebService1.asmx/CreateArray",
data:"{i:10}",
dataType:'json',
success:function(result){
alert(result.d.join(" | "));
}
});
});
//返回復雜類型
$("#btnPerson").click(function(){
$.ajax({
type: "POST",
contentType:"application/json",
url:"WebService1.asmx/GetPerson",
data:"{name:'KiMoGiGi',age:26}",
dataType:'json',
success:function(result){
var person = result.d;
var showText = [];
for(var p in person){
showText.push(p + ":" + person[p]);
}
alert(showText.join("\r\n"));
}
});
});
});
