How to get $index of angular.forEach

how can i get a $index of items angular.forEach()?

I want some like this:

$scope.data = {
  "name": "foo",
  "info": "bar"
}

angular.forEach($scope.data, function (value, key) {

  console.log($index + ' - ' + value.name + ' - ' + value.info)

})

If you were iterating through an array the second parameter in the function - which in your case is key - is the index.

If iterating through an object, like you are now, you cannot access an index. You'd have to loop it through with a for in loop like so:

var i = 0;
for (var key in $scope.data) {
    if ($scope.data.hasOwnProperty(key)) {
        // Code and stuff
        i++;
    }
}

angular.forEach, element, key is the object property key or array element index and obj is the obj itself. forEach does not iterate over inherited properties because it filters using the for obj will not throw a TypeError, but rather just return the value provided. We are going to discuss Angular.forEach function. Angular has a very rich API with many functions and directives. forEach is a function reside in `ng` Module. forEach invokes the iterator function for each item in an array or object.

In case of Array of any type we can access to its index like below:

anArrayOfMyObjects.forEach(
(element,index) =>{
 console.log('index of current item in array : ' + index)
 });

ngRepeat, $index, number, iterator offset of the repeated element (0..length-1) It is possible to get ngRepeat to iterate over the properties of an object using the following syntax: forEach(function(el) { el.age = el.age + 5; }); }; $scope.copy = function()  Fetch Object values in array using angular.foreach Example July 23, 2019 by admin In this Post We Will Explain About is Fetch Object values in array using angular.foreach With Example and Demo.Welcome on infinityknow.com – Examples , The best For Learn web development Tutorials,Demo with Example!

In the Function [function (value, key)] ==> Key is the index of the foreach loop.

ForEach Loop in AngularJS | Angular forEach Function, ForEach Loop in Angular invokes the iterator function once for each item the key is the array element index or object property key, and obj is the comments section of “ForEach Loop in Angular” and we will get back to you. The forEach function in AngularJS The Angular forEach function can be used to perform some action for each item in a given object or array. The iterator function in forEach is invoked for each item of array or object. forEach Array example Display index/values by forEach This is almost similar to the foreach loop in other programming …

NgForOf, The function receives two inputs, the iteration index and the node object ID. If trackBy is given, Angular tracks changes by the return value of the function. Using angular.forEach we will check whether a person is Male or Female, if male then the variable "male" will increase its value by one and in this way all the users and their genders will be checked and finally the output will be provided.

4 Example(s) of angular.foreach, In this example, We have 'values' as an array object and angular. forEach , Push will add values from ['A', 'B', 'C', 'D'] array to val array and index of ['A', 'B', 'C'​  The Foreach function can help you to read each element using key of object or index of array. 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. Syntax. angular.forEach(obj, iterator, [context]);

Angular forEach explained with 2 examples, The iterator function in forEach is invoked for each item of array or object. forEach Array example Display index/values by forEach. This is almost similar to the  Using Angular forEach() with an Object In the first example, I am creating an object named employees , which has an array of data in it, such as the date of joining, name and age of each employee. I’ll use the forEach() function to loop through each value in the object and extract the values and display it (in the console) one by one.
