AngularJS: Send $http.get requests continuously until certain condition

As the title says, I want to send $http.get requests to the server until the returned results meets a condition.

This is what I tried:

var searchComplete = false;
var sendGetReq = true;

while(!searchComplete) // #2 and then jumps here
sendGetReq = false; // #1 execution reaches here
$http.get('/user/getCondition', {params: {condition: $scope.condition}).
success(function (condition, status, headers, config) {
{ searchComplete = true; }
{ sendGetReq = true; }

However, the $http.get request never goes. That statement is never reached. When I debugged, I saw that execution will come to
and then jump to
. The GET request is never sent.

Would someone please explain:

  1. Why the execution never reaches GET request and jumps back

  2. What is the recommended way to to do this continuous GET request

Thank you.


Why not put it all together inside a function and call itself if condition is meet? Like this and you should use .then and not .success:

$scope.load = function(){
  $http.get('/user/getCondition', {params: {condition: $scope.condition}).
    then(function (condition, status, headers, config) {

    if (condition){


Hope it helps =)
