嗯,JS調用WebService一共有兩種做法吧,呵呵,我就知道這兩種,路過的朋友如果知道還有其它的方法,還請指點下,共同進步麼,呵呵。嗯,直接貼源碼吧。 法一: <%@ Page Language="C#" CodeFile="Default.aspx.cs" Inherits="_Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server">
<title>測試javascript調用WebService</title>
<script type="text/javascript" language=javascript>
function test()
{
//實際上HelloWorld函數中只有一個參數,這裡的第2個"test2"是用來接收傳回值的
//如果沒有傳回值則不需要
WebService.HelloWorld("Qinggeer",test2);
} function test2(str)
{
alert(str); }
</script> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />
</Services>
</asp:ScriptManager> <input id="Button1" type="button" value="button" onclick="javascript:test();" />
</form> </body> </html> WebService代碼: using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; /// <summary> /// WebService 的摘要說明 /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.Web.Script.Services.ScriptService] public class WebService : System.Web.Services.WebService { public WebService () {
//如果使用設計的組件,請取消注釋以下行
//InitializeComponent(); }
[WebMethod] public string HelloWorld(string str) { return str; }
[WebMethod] public string SayHello(string Name) {
return "Hello " + Name; }
} 法二: <%@ Page Language="C#" CodeFile="Test.aspx.cs" Inherits="Test" %> <!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> <title> Call webservice with javascript and xmlhttp. </title> </head> <script language="javascript" type="text/javascript"> function RequestByGet(url,data)
