AngularJS pass a scope variable name as a function parameter


AngularJS pass a scope variable name as a function parameter

it should still fix some issue Since $scope is just an object with properties, you can use bracket notation:
code :
$scope[partialtype];

AngularJS: When to pass $scope variable to function

AngularJS: When to pass $scope variable to function

will help you I would prefer to always pass in arguments to the function:
It's clearer what parameters the function expects. It's easier to unit-test because all parameters are injected into the function.(good for unit- testing)
code :
$scope.addToDo = function(){
   //This declaration is not clear what parameters the function expects.
   if ($scope.parameter1){
      //do something with parameter2
   }    
}
$scope.addToDo = function(){
    //This declaration is not clear what parameters the function expects.
    if ($scope.someobject.parameter1){ //worse

    }    
}
//It's clearer that the function expects parameter1, parameter2
$scope.addToDo = function(parameter1, parameter2){
   if (parameter1){
      //do something with parameter2
   }    
}
//assume that parameter1 belongs to $scope, parameter2 is inherited from parent scope.
    $scope.addToDo = function(parameter2){ 
        if ($scope.parameter1){ //parameter1 could be accessed directly as it belongs to object, parameter2 should be passed in as parameter.
            //do something with parameter2
        }   
    }

I hope this helps . I'm trying to loop through a mysql result and run an anonymous function on each record, but I'm having some trouble with variable scope. The problem is part of a much bigger flow but I've created a simplified example here which demonstrates the issue simply: , Pass $res as an argument "by reference" to your callback using use
code :
function runLoop($some_mysql_resource){
    $res = 'RESULTS: ';
    sqlEach($some_mysql_resource, function($sql) use (&$res) {
        $res .= $sql['id'].',';
    })
    return $res;
);

seems to work fine So, I am listening to the NgKeyup event, which fires a function that receives the current NgModel as follows: , Use the scope's $eval method:
code :
$scope.filterValue = function(ngModelName, type, $event){

    //works for simple names
    //$scope[ngModelName];

    //works for complex names, '$ctrl.x', 'x[$index]', etc.
    console.log($scope.$eval(ngModelName));

};

I think the issue was by ths following ,
is it possible to pass a $scope variable to another function inside the controller ?
code :
.controller('mycontroller', function($scope) {

    function makesPostRequest() {
       console.log($scope);
    }

    $scope.getResult = function(params) {
       console.log($scope);
    }

});
$scope.getResult = function (rid) {
    GetResultFile.getResult($scope.id, rid)
                            ^^^^^^^^^
        .then(function (data) {
            console.log("Download erfolgreich");
            console.log("data.status");
        }, function (data) {
            console.log("Download ERROR!");
            console.log(data.status);
        })
};
