Web services with javascript using .net

Question

Hi. I have an active web services called test. So I have this piece of code in HTML writen in Javascript: function GetURL() { //////del so xmlhttp request ///var req2 = new XMLHttpRequest(); ///var url=http://localhost/test/Service1.asmx/Hi?a=3; /// req2.onreadystatechange = processReqChangeAttributes; /// req2.open(GET url true); ///req2.send(null); ///var returnValue=req2.responseText; ///document.Form1.t.value=returnValue; ////// var cc=3; var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); var url=http://localhost/test/Service1.asmx/Hello; xmlhttp.open(GET url false); //xmlhttp.send(url); //xmlhttp.send(a=3); //var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); //var url=http://localhost/test/Service1.asmx/Hi?a=3; //xmlhttp.open(POST urltrue); //xmlhttp.setRequestHeader(Hostlocalhost); //xmlhttp.setRequestHeader(Content-Typeapplication/x-www-form-urlencoded); //xmlhttp.setRequestHeader(Content-Length12); //xmlhttp.send(); //xmlhttp.send(url); xmlhttp.send(a=3); var returnValue=xmlhttp.responseText; //var returnValue=xmlhttp.responseXML.xml; //alert(xmlhttp.responseXML.xml); //return returnValue; document.Form1.t.value=returnValue; var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); function GetURL() { //////del so xmlhttp request ///var req2 = new XMLHttpRequest(); ///var url=http://localhost/test/Service1.asmx/Hi?a=3; /// req2.onreadystatechange = processReqChangeAttributes; /// req2.open(GET url true); ///req2.send(null); ///var returnValue=req2.responseText; ///document.Form1.t.value=returnValue; ////// var cc=3; var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); var url=http://localhost/test/Service1.asmx/Hello; xmlhttp.open(GET url false); //xmlhttp.send(url); //xmlhttp.send(a=3); //var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); //var url=http://localhost/test/Service1.asmx/Hi?a=3; //xmlhttp.open(POST urltrue); //xmlhttp.setRequestHeader(Hostlocalhost); //xmlhttp.setRequestHeader(Content-Typeapplication/x-www-form-urlencoded); //xmlhttp.setRequestHeader(Content-Length12); //xmlhttp.send(); //xmlhttp.send(url); xmlhttp.send(a=3); var returnValue=xmlhttp.responseText; //var returnValue=xmlhttp.responseXML.xml; //alert(xmlhttp.responseXML.xml); //return returnValue; document.Form1.t.value=returnValue; var url=http://localhost/test/Service1.asmx/Hello; xmlhttp.open(GET url false); var returnValue=xmlhttp.responseText; document.Form1.t.value=returnValue; And i have an HTML control with a name 't' where I preview the result. This code works cause the method Hello which I'm invoking is without parameters. But if I invoke one other mathod called 'Hi' which has one paremeterlike this: var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); function GetURL() { //////del so xmlhttp request ///var req2 = new XMLHttpRequest(); ///var url=http://localhost/test/Service1.asmx/Hi?a=3; /// req2.onreadystatechange = processReqChangeAttributes; /// req2.open(GET url true); ///req2.send(null); ///var returnValue=req2.responseText; ///document.Form1.t.value=returnValue; ////// var cc=3; var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); var url=http://localhost/test/Service1.asmx/Hello; xmlhttp.open(GET url false); //xmlhttp.send(url); //xmlhttp.send(a=3); //var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); //var url=http://localhost/test/Service1.asmx/Hi?a=3; //xmlhttp.open(POST urltrue); //xmlhttp.setRequestHeader(Hostlocalhost); //xmlhttp.setRequestHeader(Content-Typeapplication/x-www-form-urlencoded); //xmlhttp.setRequestHeader(Content-Length12); //xmlhttp.send(); //xmlhttp.send(url); xmlhttp.send(a=3); var returnValue=xmlhttp.responseText; //var returnValue=xmlhttp.responseXML.xml; //alert(xmlhttp.responseXML.xml); //return returnValue; document.Form1.t.value=returnValue; var url= http://localhost/test/Service1.asmx/Hi?a=3 ; xmlhttp.open(GET url false); var returnValue=xmlhttp.responseText; document.Form1.t.value=returnValue; function GetURL() { //////del so xmlhttp request ///var req2 = new XMLHttpRequest(); ///var url=http://localhost/test/Service1.asmx/Hi?a=3; /// req2.onreadystatechange = processReqChangeAttributes; /// req2.open(GET url true); ///req2.send(null); ///var returnValue=req2.responseText; ///document.Form1.t.value=returnValue; ////// var cc=3; var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); var url=http://localhost/test/Service1.asmx/Hello; xmlhttp.open(GET url false); //xmlhttp.send(url); //xmlhttp.send(a=3); //var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); //var url=http://localhost/test/Service1.asmx/Hi?a=3; //xmlhttp.open(POST urltrue); //xmlhttp.setRequestHeader(Hostlocalhost); //xmlhttp.setRequestHeader(Content-Typeapplication/x-www-form-urlencoded); //xmlhttp.setRequestHeader(Content-Length12); //xmlhttp.send(); //xmlhttp.send(url); xmlhttp.send(a=3); var returnValue=xmlhttp.responseText; //var returnValue=xmlhttp.responseXML.xml; //alert(xmlhttp.responseXML.xml); //return returnValue; document.Form1.t.value=returnValue; I get this response:Request format is invalid: Any ideas?Anyone? P.S:I am using visual studio.netand i am inserting the next code in web.config file: webServices > protocols > add name =HttpGet/> add name =HttpPost/> protocols > webServices > It wont work without it. function GetURL() { //////del so xmlhttp request ///var req2 = new XMLHttpRequest(); ///var url=http://localhost/test/Service1.asmx/Hi?a=3; /// req2.onreadystatechange = processReqChangeAttributes; /// req2.open(GET url true); ///req2.send(null); ///var returnValue=req2.responseText; ///document.Form1.t.value=returnValue; ////// var cc=3; var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); var url=http://localhost/test/Service1.asmx/Hello; xmlhttp.open(GET url false); //xmlhttp.send(url); //xmlhttp.send(a=3); //var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); //var url=http://localhost/test/Service1.asmx/Hi?a=3; //xmlhttp.open(POST urltrue); //xmlhttp.setRequestHeader(Hostlocalhost); //xmlhttp.setRequestHeader(Content-Typeapplication/x-www-form-urlencoded); //xmlhttp.setRequestHeader(Content-Length12); //xmlhttp.send(); //xmlhttp.send(url); xmlhttp.send(a=3); var returnValue=xmlhttp.responseText; //var returnValue=xmlhttp.responseXML.xml; //alert(xmlhttp.responseXML.xml); //return returnValue; document.Form1.t.value=returnValue;

I got it!Here is the solution: var xmlhttp = new ActiveXObject(Microsoft.XMLHTTP); var url=http://localhost/test/Service1.asmx/Hi; //here is the service call xmlhttp.open(POST url false); xmlhttp.setRequestHeader(Content-Typeapplication/x-www-form-urlencoded); xmlhttp.setRequestHeader(Content-Length12); xmlhttp.send(a=3);//here are the parameters var returnValue=xmlhttp.responseText; //xml response will be here document.Form1.t.value=returnValue; I've been using GETand I cannot use parameters with GET requests.
