- function in module ng
Invokes the iterator
function once for each item in obj
collection, which can be either an object or an array. The iterator
function is invoked with iterator(value, key, obj)
, where value
is the value of an object property or an array element, key
is the object property key or array element index and obj is the obj
itself. Specifying a context
for the function is optional.
It is worth noting that .forEach
does not iterate over inherited properties because it filters using the hasOwnProperty
method.
Unlike ES262's Array.prototype.forEach, providing 'undefined' or 'null' values for obj
will not throw a TypeError, but rather just return the value provided.
var values = {name: 'misko', gender: 'male'}; var log = []; angular.forEach(values, function(value, key) { this.push(key + ': ' + value); }, log); expect(log).toEqual(['name: misko', 'gender: male']);
Usage
angular.forEach(obj, iterator, [context]);
