javascript - How to update current values inside an angular.forEach()? -


i trying convert portion of object's values integer values 1 or 0 boolean values true or false.

the structure follows:

angular.foreach(a.b.c, function (options) {     ...     angular.foreach(options, function (value, option) {         if (value == 0) {             option = false;         } else {             option = true;         }         console.log(option + " = " + value);  // shows correct results;     } } console.log(a.b.c) // when navigating options, options have not changed integer values.

what missing?

you changing value of local variable false/true, not changing value of object.

var array = [{    key: 1  }, {    key: 0  }];  angular.foreach(array, function(options) {    angular.foreach(options, function(value, option) {      if (value == 0) {        options[option] = false;      } else {        options[option] = true;      }      //the if else can simplified      //options[option] = value != 0;      console.log(option + " = " + options[option]);    })  })    console.log(array);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

if know key updated then

var array = [{    key: 1  }, {    key: 0  }];  angular.foreach(array, function(options) {    options.key = options.key != 0;  })    console.log(array);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
