嗯,JS调用WebService一共有两种做法吧,呵呵,我就知道这两种,路过的朋友如果知道还有其它的方法,还请指点下,共同进步么,呵呵。嗯,直接贴源码吧。 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>测试javascript调用WebService</title> <script type="text/javascript" language=javascript> function test() { //实际上HelloWorld函数中只有一个参数,这里的第2个"test2"是用来接收返回值的 //如果没有返回值则不需要 WebService.HelloWorld("Qinggeer",test2); } { alert(str); </script> </head> <body> id="form1" runat="server"> ID="ScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="WebService.asmx" /> </Services> </asp:ScriptManager> type="button" value="button" onclick="javascript:test();" /> </form> </body> </html> WebService代码: using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; /// <summary> /// WebService 的摘要说明 /// </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 () { //如果使用设计的组件,请取消注释以下行 //InitializeComponent(); [WebMethod] { str; [WebMethod] 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) { xmlhttp; try { xmlhttp= new ActiveXObject("Microsoft.XMLHTTP"); } catch(e) |
