autocomplete-remote multiple returns undefined error on json data returned from asp.net 2.0 webservice

in Using jQuery UI • 12 years ago

Hi, I have a hard time getting this one work. please give some hint and I have some deadline to make.

here is the web service

    [WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string GetJsonMemberCodes(string term)
    {
        suggestions = new List<Members>();

Data dt = new Data();

suggestions = dt.GetJsonMemberCodes(term);

        }
     return new JavaScriptSerializer().Serialize(suggestions);

    }

here is the data the server web service returned.

<?xml version="1.0" encoding="utf-8" ?>

<string xmlns="http://tempuri.org/">[{"ID":"106720","LABEL":"106720","VALUE":"106720},{ID":"106729","LABEL":"106729","VALUE":"106729"}]</string>

here is the page that is calling it

link type="text/css" href="../../App_Themes/css/base/jquery.ui.all.css" rel="stylesheet" />

.ui-autocomplete-loading { background: white url('~/images/ui-anim_basic_16x16.gif') right center no-repeat; }

</style>

function() {

function split(val) {

return val.split(/,\s*/);

}

function extractLast(term) {

return split(term).pop();

}

"input[ID*='txtMemberID']").autocomplete({

// source: function(request, response) {

// $.getJSON("RptMemberIDAutoComplete.asmx/GetJsonMemberCodes", {

// term: extractLast(this.value)

// }, response);

// },

// $.jsonService({url: 'RptMemberIDAutoComplete.asmx',method: '/GetJsonMemberCodes',params: extractLast(this.value)});

// },

source:

function(request, response) {

$.ajax({

type:

"POST",

url:

"RptMemberIDAutoComplete.asmx/GetJsonMemberCodes",

contentType:

"application/json; charset=utf-8",

dataType:

"json",

data:

"{'term': '" + extractLast(this.value) + "'}",

success:

function(result) {alert(result.d);

// response($.map(data, function(item) {

// return {

// ID:item.ID,

// label: item.ID,

// value: item.ID

// }

// }))

}

});

search:

function() {

// custom minLength

var term = extractLast(this.value);

if (term.length < 2) {

return false;

}

focus:

function() {

// prevent value inserted on focus

return false;

select:

function(event, ui) {

var terms = split( this.value );

// remove the current input

terms.pop();

// add the selected item

terms.push( ui.item.value );

// add placeholder to get the comma-and-space at the end

terms.push(

"");

this.value = terms.join(", ");

return false;

}

});

</script>

input id="txtMemberID" size="50" />

figured out myself. this is working version using same web service. parameter needs to be parsed in with .toJson in jquery.json-2.2.min.js downloadable in

http://code.google.com/p/jquery-json/downloads/list

link href="../../App_Themes/css/ui-lightness/jquery-ui-1.8.4.custom.css" rel="stylesheet" type="text/css" />

script type="text/javascript" src= "../../Scripts/js/jquery-1.4.2.min.js"></script>

script type="text/javascript" src="../../Scripts/js/jquery-ui-1.8.4.custom.min.js"></script>

script type="text/javascript" src="../../Scripts/js/jquery.json-2.2.min.js"></script>

//autocomplete member id

"input[ID*='txtMemberId']").autocomplete({

source:

function(request, response) {

$.ajax({

url:

"../../RptMemberIDAutoComplete.asmx/GetJsonMemberCodes",

type:

"POST",

contentType:

"application/json; charset=utf-8",

data: $.toJSON({

'Mem': extractLast(request.term) }),

dataType:

"json",

success:

function(msg) {

//alert(msg.d);

var data = eval("(" + msg.d + ")");

response(

$.map(data,

function(item) {

return {

label: item.ID +

" | " + item.NM,

value: item.ID

}

})

);

//response ending tag

}

//success ending tag

//,

//error: function(msg) {

//alert(msg);

// }

});

//ajax ending tag

search:

function() {

// custom minLength

var term = extractLast(this.value);

if (term.length < 2) {

return false;

}

focus:

function() {

// prevent value inserted on focus

return false;

select:

function(event, ui) {

var terms = split( this.value );

// remove the current input

terms.pop();

// add the selected item

terms.push( ui.item.value );

// add placeholder to get the comma-and-space at the end

terms.push(

"");

this.value = terms.join(", ");

return false;

}

});
