jquery - autocomplete specify more parameters? -

i'm using jquery ui autocomplete

if in jquery / asp.net:

 $("#<%= txtname.clientid %>").livequery(function () {                 $(this).autocomplete('loadnames.ashx')              .result(function (event, data, formatted) { // data[0] : name, data[1] :addressid                  // set selected email id hidden field                  $("#<%= hdnid.clientid %>").val(data[1]);                  if (data[1] != "0") {                      var url = "http://emps/newentry.aspx?id=" + data[1];                      window.open(url);                  }                  else {                  }              });             }); 

this works great, want add more parameters minchars, etc. try this:

$("#<%= txtname.clientid %>").livequery(function () {                 $(this).autocomplete({source:"loadnames.ashx", delay:100, minchars:2})              .result(function (event, data, formatted) { // data[0] : name, data[1] :addressid                  // set selected email id hidden field                  $("#<%= hdnid.clientid %>").val(data[1]);                  if (data[1] != "0") {                      var url = "http://emps/newentry.aspx?id=" + data[1];                      window.open(url);                  }                  else {                  }              });             }); 

this doesnt work longer. how can add more parameters minchars, delay, etc this?

from comments wanted see .ashx file, there no issue this. want add additional parameters autocomplete:

 public class loadnames : ihttphandler     {          public void processrequest(httpcontext context)         {             dataset ds = null;             dictionary<long, string> lstaddresses = new dictionary<long, string>();              ds = getloginnames();              if (ds.tables[0].rows.count > 0)             {                 foreach (datarow dr in ds.tables[0].rows)                 {                     lstaddresses.add(convert.toint64(dr["loginid"].tostring()), dr["login"].tostring());                 }                 stringbuilder builder = new stringbuilder();                  foreach (keyvaluepair<long, string> item in lstaddresses)                 {                     builder.append(string.format("{0}|{1}|{2}",                           item.value,                           item.key,                           environment.newline));                 }                 context.response.write(builder.tostring());             }         }          public dataset getloginnames()         {             sqlcommand cmdselect = default(sqlcommand);             sqlconnection conmydata = default(sqlconnection);             sqldataadapter daissues = default(sqldataadapter);             system.data.dataset ds = null;              conmydata = null;              //try , make connection                try             {                 conmydata = new sqlconnection(system.configuration.configurationmanager.appsettings["connstring"]);                 cmdselect = new sqlcommand("selfullnames", conmydata);                  var _with1 = cmdselect;                 _with1.commandtype = system.data.commandtype.storedprocedure;                 //add parameters                 _with1.parameters.add("@inactive", sqldbtype.int).value = 2;                 daissues = new sqldataadapter();                 daissues.selectcommand = cmdselect;                 ds = new system.data.dataset();                 daissues.fill(ds);                  return ds;                 //catch exceptions might thrown             }             catch (exception e)             {                 throw e;                 //clean , close resources             }                         {                 conmydata.close();                 cmdselect = null;                 conmydata = null;             }         }          public bool isreusable         {                         {                 return false;             }         } 

$(document).on("keydown.autocomplete", "#<%= txtname.clientid %>", function (e) {     $(this).autocomplete({         source: "loadnames.ashx",         delay: 100,         minlength: 2     }).result(function (event, data, formatted) {         $("#<%= hdnid.clientid %>").val(data[1]);         if (data[1] != "0") {             var url = "http://emps/newentry.aspx?id=" + data[1];             window.open(url);         } else {}     }); });
