passing variable to array list

Question

My code looks like:

  $scope.filters = [{
    name: 'cat1',
    limit: 12 

}, {
    name: 'cat2',
    limit: 12
}];

Can I simply call

limit: varname or $scope.name

does it need to be in a specific format?

It is not clear what you are asking. Do you want to add an entry to the array? do you want to access the value of the properties? — Patrick Murphy

I'd simply like to change the limit value via a variable rather than hard coded — Poiro

You have the Array of Javascript Objects that looks like this

[ // array
  { // index 0
      name: 'cat1',
      limit: 12 
  }, 
  { // index 1
      name: 'cat2',
      limit: 12
  }
] // end array

That is assigned to $scope.filters. Now to access or set a specific objects contained in the array you must specify which element using the array index in square brackets.

console.log( $scope.filters[0] ); // {name: 'cat1', limit: 12}

Then you can use a property name to access the properties of one of the objects

var oldLimit = $scope.filters[0].limit; // = 12
$scope.filters[0].limit = oldLimit + 2; // = 14

So to recap $scope is an object, with the sub-element filters that is an array, that contains objects with the properties name and limit.

$scope.filters[index].propertyName
