variable scope issue in Javascript and angular

Question

How can i solve the issue of scope of variable in the below case.

 Myapp.controller('MyController', ['$scope', function ($scope) { var formvalues = {}; $scope.somebuttonclick = function(){ mycont.somefunctionB(); }; var mycont = { init: function(){ formvalues.init = "some value init"; this.somefunctionA(); }, somefunctionA: function(){ formvalues.a= "some value a"; alert(formvalues.init); //comes undefined when called from mycont.init }, somefuntionB: function(){ formvalues.b = "some valuee b"; alert(formvalues.init); // comes "some value init" when called from buttonclick } }; }]); 

Calling through button click, variable are defined correctly but when called from inside of mycont method, it say undefined. How to solve this

Answer 1

你要么需要绑定this的功能，或者只是访问功能这样的对象属性：

mycont.someFunctionA()

Answer 2

Don't know what exactly you are looking for but check this:

Myapp.controller('MyController', ['$scope','$log', function ($scope, $log) {

    var formvalues = {};/*this is empty at first*/

    var mycont = {
        init: function(){
            formvalues.init = "some value init";
        },
        somefunctionA: function(){
            formvalues.a= "some value a";
            /*mycont.init();*/ /*you can call it here, if not in somebuttonclick*/
            $log.log(formvalues.init);
            $log.log(formvalues.a);
        },
        somefunctionB: function(){
            formvalues.b = "some valuee b";
            /* mycont.init(); */ /*you can call it here, if not in somebuttonclick*/
            $log.log(formvalues.init);
            $log.log(formvalues.b);
        }
    };

    $scope.somebuttonclick = function(){
        mycont.init();/*you need to first call this function before you can use the value*/
        mycont.somefunctionA();
        mycont.somefunctionB();
    };
}]);
