JS代码:
var word = document.getElementById("word").value; $.ajax({ type: "POST", contentType: "application/x-www-form-urlencoded", url: "http://localhost:12805/WebService.asmx/HelloWorld", data: 'data=' + word, dataType: 'text', success: function(result) { alert("success: " + result); }, error: function(result, status) { alert("error: " + status); } });
C# WebService代码:
[WebService(Namespace = "weburl")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService] public class WebService : System.Web.Services.WebService { [WebMethod] public void HelloWorld(string data) { this.Context.Response.AddHeader("Access-Control-Allow-Origin", "*"); // CORS 跨域访问 this.Context.Response.Write(data); // 返回字符串格式 } }
WebService 默认 return 返回 XML 格式,但是使用上述方式是以字符串形式返回。
