Exploring the process of retrieving a pre-defined array within AngularJS

I'm encountering a challenge with accessing the array element in AngularJS. Here is the array:

$scope.salesentry = [
    {
        sales_id:'',
        product_id: '',
        product_category_id:'',
        sale_qty:null,
        sale_amount:null
    }
];

I am trying to update the value of the sales_id field upon clicking a button, like this:

$scope.saveData = function() {
    $scope.salesentry.sales_id='10';
});

However, I am unable to access it using the above method. Can anyone guide me on how to achieve this?

Answer №1

salesentry is actually an array, meaning you must first access a particular element from it by using [0].

Therefore, your code should now look like this:

$scope.saveData = function() {
    $scope.salesentry[0].sales_id='10';
});

Answer №2

Are you looking to modify the sales_id for each instance of salesentry?

If so, you can accomplish this by using:

angular.forEach($scope.salesentry, function(value, key){
    value.sales_id = 10;
});

Answer №3

To properly access the array data, make sure to index it correctly.

$scope.orders[1].order_id = '20'

Furthermore, avoid adding unnecessary commas in your code.
