Combine a variable with variable value in Javascript

Question

I am trying to do something like this in Angular javascript (a simplified code):

var modelName = \"date\";

if (attrs.hasOwnProperty(\'today\')) {
   scope.model         


        

Answer 1

You can access properties of objects using square brackets.

var modelName = "date";

if (attrs.hasOwnProperty('today')) {
   scope[modelName] = new Date();
}
