javascript - Populate DropDownList by JSON -


-- controller --

[webmethod] public actionresult getsellers() {     list<seller> sellers = db.sellers.tolist();      return json(sellers, jsonrequestbehavior.allowget); }

-- view --

@html.dropdownlistfor(x => x.sellerid, new selectlist(enumerable.empty<selectlistitem>()))

-- javascript --

<script type="text/javascript">     $('#deptid').change(function () { // deptid dropdownlist         $.getjson('/salerecords/getsellers'), null, function (result) { // path             var ddl = $('#sellerid'); // seller ddl             ddl.empty();             $('sellers').show(); // div (it's display: none)             $(result).each(function () {                 ddl.append(                 $('<option />', {                     value: this.id                 }).html(this.name)                 );             });         };     }); </script>

what's wrong? i've debugged in controller, , sellerslist has 3 registries, doesn't appear in view, what's problem?

this might issue

$.getjson('/salerecords/getsellers'), null, function (result) // should throw error

try

$.getjson('/salerecords/getsellers') .done(function(result) {         var ddl = $('#sellerid');         ddl.empty();         $('sellers').show();         $(result).each(function () {             ddl.append(             $('<option />', {                 value: this.id             }).html(this.name)  });  .fail(function(jqxhr) {console.log(jqxhr.responsetext)});
