javascript - Getting error while sorting records in descending order by Id with orderby clause in Angular js -

i trying display records in descending order of id property.

but getting error below in browser console:

[orderby:notarray] expected array received: {"name":"abc","emailid":"abc@yahoo.com","salary":4000}

this code:

 <table>        <tr>           <td ng-repeat="item in user " ng-if="$odd" >           </td>        </tr>     </table>      <table>        <tr>           <td ng-repeat="item in user " ng-if="$even" >           </td>        </tr>     </table>                <tr ng-repeat="item in user | orderby: '-id'    ">              </td>   function displaydata() {         myservice.getlist().then(         function (data) {             $scope.user = data            }, function (reason) {       })     } 

json output:

    [             {               "id":5,              "name": "abc",              "emailid": "abc@yaoo.com",              "salary" : 4000             },             {           "id":11,              "name": "yyy",              "emailid": "abc@yaoo.com",              "salary" : 4000             },             {               "id":7,              "name": "iii",              "emailid": "abc@yaoo.com",              "salary" : 4000             },             {'               "id":3,              "name": "www",              "emailid":"abc@yaoo.com",              "salary" : 4000             }            ] 

the problem assignment:

function displaydata() {         myservice.getlist().then(         function (data) {             $scope.user = data            }, function (reason) {       })     } 

function .then() returns promise object allow chaining: .then().then(), , because returns object that's why receive notarray error.

to avoid reference error can specify $scope.user empty arrray earlier, assign results it.

function displaydata() {         $scope.user = [];         myservice.getlist().then(         function (data) {             $scope.user = data            }, function (reason) {       }) } 

this worked successfully...
