循環嵌套$ http js函數

Question

我有兩個javscript async $ http函數：我正在使用角度js以嵌套方式動態創建表。

我想要某種方式來同步執行這些功能。

現在，j循環只對resultB的初始值執行。一旦表被編譯，然後fuctB被執行爲i的所有值。

$scope.funcA = function() { 
    $http({ 
    method : 'GET', 
    url : url,     
    }).then(function successCallback(response) { 
    $scope.resultA = response.data; 
    //process based on $scope.resultA 
    for (var i = 0; i < $scope.resultA .length; i++){ 
     $scope.funcB($scope.resultA[i][0]); 
     for(j=0; j<$scope.resultB .length; j++){ 
     //process based on $scope.resultB 
     }      
    } 
    $compile(/* document element*/); 

    }, function errorCallback(response) { 
    console.log(response.statusText); 
    }); 
} 

$scope.funcB = function(k){ 
    $http({ 
    method : 'GET', 
    url : url+k 
    data: k , 
    }).then(function successCallback(response) { 
    return $scope.resultB = response.data; 
    }, function errorCallback(response) { 
    console.log(response.statusText); 
    }); 
} 

Answer 1

$scope.funcB = function(i) { 
    // return promise 
    return $http({.... 
     data: i ; 
     $scope.resultB = response.data; 
    }; 
} 


$http{..... 
$scope.resultA =response.data; 
for(var i =0; i< $scope.resultA.length; i++{ 
    process based on i value 
    $scope.funcB(i).then(function() { 
    // execute this part after promise completed (request B has ended and returned result) 
    for(var j =0; j<$scope.resultB.length;j++{ 
     process based on i and j; 
     } 
    } 
    compile(the document element); 
}); 
}
