Declaring a member function in JS

Question

I\'ve tried two ways to declare a member function in JS:

function init() {
    var name = \"Mozilla\";
    function displayName() {
        alert(name);
             


        

Answer 1

The following should work:

function Init() {
    var name = "Mozilla";
    this.displayName = function() {
        alert(name);
    }
}
a = new Init();
a.displayName()
