ASP.NET calling a web service from javascript
Calling a web service from javascript should be a very easy task.
The other day I spent too
much time trying to call a WebService using Prototype js library so I decided to
post the code here in case anyone else encounter the same problem.
Server side code:
[WebService]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld(string testParam)
{
return testParam;
}
}
Prototype syntax:
new Ajax.Request('WebServices/WebService.asmx/HelloWorld',
{
postBody: "{testParam:'hello'}",
method: 'post',
contentType: 'application/json; charset=utf-8',
onSuccess: function(transport) {
alert(transport.responseText);
},
onFailure: function(transport) {
alert(transport.responseText);
}
});
JQuery syntax:
$.ajax({
type: "POST",
url: "WebServices/WebService.asmx/HelloWorld",
data: "{testParam:'hello'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(result){
alert(result.d);
}
});
That's it.
Hope it help someone out
there.
Happy coding!
