Call a variable function in AngularJS

Question

In my app.js I have defined functions like this:

var func1 = function(v1,v2,v3) {
  .
  .
}

var func2 = function(v1,v2,v3) {
  .
  .
}

In my controller.js :

var action = "";

if(..) { action = 'func1';}
else {action = 'func2'}

action(a1,a2,a3);

However, I get an error, saying that action is not a function. How can I access func1 and func2`` like this?

Answer 1

try removing quotes, like, change:

if(..) { action = 'func1';}
else {action = 'func2'}

to

if(..) { action = func1;}
else {action = func2;}

Added: you are assigning string to your action variable when you add quotes for the func1 , you can check it doing:

var func1 = function(v1,v2,v3) {
  alert("first");
};
var test_this = func1;
console.log( typeof test_this); //gives you function

where as

var test_this = 'func1'; //with quotes added
console.log( typeof test_this); //gives you string

You're trying to access the function from a string. I'm no expert but you could just try

if (..) {
    func1(a1, a2, a3);
} else {
    func2(a1, a2, a3);
}
