Javascript function 里面一个 function 访问

Question

how can I access a function inside a function? Here's an example:

function fun1() {
  //some code here
  var example = function (){
    //some code here
  }
  return {
    example: example
  }
}

when i try to access it like this fun1.example() I get error fun1.example is not a function. What am I doing wrong?

Answer 1

Please look at comments for more info

function fun1() {
  //some code here
  var example = function () {
    //some code here
  };
  return {
    example: example,
  };
}
// Fun1 is funtion, In funtion there is no property like example

// So when you call fun1.example , which undefined. Is not a function
fun1.example() // Error here

const obj = fun1() // call funtion to get obj

obj.example() // No error

You have to run the code as fun().example(), or store the result of fun() into a variable and then run it, like this:

var fun = ();
fun.example();
