Unable to retrieve any values using the for each loop in AngularJS

Question

Unable to retrieve any values using the for each loop in AngularJS

Having an issue with my Angular.js foreach loop. When I use

console.log('course data',response.data);

the output looks like this:

course data [Object, Object, Object]
0: Objectcourse_name: "Master of computer 
1: Objectcourse_name: "Bachelor of Technology"
2: Objectcourse_name: "Master in Technology"
length: 3__proto__: Array[0]

Below is my code for the Angular foreach loop:

angular.forEach(response.data, function(value, key){
       console.log(key + ': ' + value);
     });

However, when I run the code, the console message shows:

0: [object Object]
1: [object Object]
2: [object Object]

I'm not able to get the key name and its value. Can someone help me fix this problem?

Answer №1

give this a shot

using the Angular forEach method to iterate through response data and log each object's name and value properties to the console
angular.forEach(response.data, function(obj){
   console.log(obj.name + ': ' + obj.value);  });

This code snippet demonstrates how to access the key and value of objects in your data.

It appears that the data you're working with is in the form of an array containing objects. You may want to consider using this approach:

angular.forEach(response.data, function(key, value){
   console.log(key + ': ' + value.Objectcourse_name);
});

Although your code is perfectly fine, there seems to be a problem with the data in your array. The missing quotation mark against Master of Computer may be causing issues. Below is another example for clarification.

course data [Object, Object, Object]
0: Objectcourse_name: "Master of computer" 
1: Objectcourse_name: "Bachelor of Technology"
2: Objectcourse_name: "Master in Technology"
length: 3__proto__: Array[0]

angular.forEach

Invokes the iterator function once for each item in obj collection, which can be either an object or an array.

var obj = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(obj, function(value, key) {
  console.log(key + ': ' + value);
});
// it will log two iteration like this
// name: misko
// gender: male

Instead of printing an object, you are actually concatenating strings together. Give this a try:

console.log(key, value)
