TypeError: Cannot read property 'push' of undefined, JavaScript

Question

I\'m working in this Angular project where user submits a comment form, and the new comment is added to the comments that\'s already posted. Here is my code.

Answer 1

The comments you have declared is an Object. Just change your declaration to an array ,

From:

$scope.comments = {};

To:

$scope.comments = [];

EDIT: If you need to Push new Object, You need to make your Comments as Array of Object like this and push the new Object

$scope.comments = { 
    1: {name:'',review:'',comment:'',uptime:'',gravatar:''}
}

 $scope.comments.push({name:'rukshi', review:'test comment',comment:'yet another comment',uptime:'',gravatar:''});
