Question

The Angular ternary operator can be used in conjunction with functions for optimal

Consider this scenario: I have two functions that are triggered by a button click:

<button ng-click="functionOne || functionTwo()"></button>

However, I want to optimize this setup so that the functions are only called if they return a value. If they don't return anything, I would like them to not be called at all and simply return null or another default value. I am currently exploring if it is possible to achieve this using a ternary operator, something like:

<button ng-click="condition ? functionOne || functionTwo() : null"></button>

In this case, the functions will only be executed if condition evaluates to true.

I have experimented with this approach, but it doesn't seem to work as expected :|

Answer №1

To make the function cleaner, you can pass the condition as an argument into the function for it to check. If true, it will execute some code; if false, nothing will happen.

Do you find this method more organized?

<button ng-click="functionTwo(condition)"></button>

Then, define the function like this:

$scope.functionTwo = function (conditon) {
  if (condition) {
    //perform desired actions...
  }
};

If you initially wanted a return statement in functionOne, feel free to modify it accordingly.

In case you prefer using a ternary operator, although I think it adds complexity, you can do so as shown here:
