Hello,
I followed the directions in this post: http://stackoverflow.com/questions/457183/how-can-we-integrate-jquery-autocomplete-using-asp-net-webservie-and-sql-databas
to make jquery-autocomplete plugin work with my webservice on asp.net, but it just won't work.
Autocomplete works if I do local data. I'm also able to make calls to my webservice using jquery ajax. Can anybody tell me what I'm doing wrong? Code:
//This jquery ajax call works perfectly
function AjaxTest() {
$.ajax({
type: "POST",
url: "/Services/OSServices.asmx/HelloWorld",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: RenderTest
});
}
//this autocomplete ajax call doesn't work. It doesn't even hit the breakpoint in the
web service
$("#lastName").autocomplete("/Services/OSServices.asmx/HelloWorld", {
parse: function(data) {
var parsed = [];
$(data).find("string").each(function() {
parsed[parsed.length] = {
data: [$(this).text()],
value: $(this).text(),
result: [$(this).text()]
};
});
return parsed;
},
datatype: "xml"
});
//this is the webservice code:
[WebService(Namespace = "http://tempuri.org")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class OSServices : System.Web.Services.WebService
{
[WebMethod]
public string[] HelloWorld()
{
string[] myArray = { "blah1", "blah2", "blah3" };
return myArray;
}
}
EDIT:
This is the response I get titled internal server error.

EDIT:
So I removed the /HelloWorld/ part from the url, and the response doesn't generate an error anymore. However, this doesn't solve my problem. I'm thinking there's another way to pass in the method name to call?
