javascript - Un-Defined index with $http. -

not sure reason got undefined index below code. checked can't find what's wrong.

   $http({     url: "php/mainload.php",     method: "get",     data: {"userid":"1"}     }).success(function(data, status, headers, config) {          console.log(data);     }).error(function(data, status, headers, config) {        // $scope.status = status;        alert(status);     }); 

php

echo $_get['userid']; 

parametere data on ajax expecting method post, if need $_get, use params instead :

$http({     url: "php/mainload.php",     method: "get",     params: {"userid":"1"}   // change `params` `data`. }).success(function(data, status, headers, config) {      console.log(data); }).error(function(data, status, headers, config) {     // $scope.status = status;     alert(status); });
