Static variables in JavaScript
How can i make a static encapsulation with self members in javascript? such as in php:
class bar{
static public $foo;
static public function set() {
self::$foo = 'a';
}
}
bar::set();
In javascript: var bar = function () { ???????? } bar.set();
Thanks!
Simply define them as properties of bar.
bar.foo = null;
bar.set = function() {
bar.foo = "a";
}
Here's a nice overview:
var bar = function() {
// Private instance variables
var a = 1;
// Public instance variables
this.b = 5;
// Privileged instance methods
this.c = function() {
return a;
}
};
// Public instance methods
bar.prototype.d = function() {
return ++this.b;
}
// Public static variables
bar.foo = null;
// Public static methods
bar.set = function() {
bar.foo = "a";
}
Make a closure that creates the object and returns it. Inside the closure you can declare local variables, and they are private to the scope:
var bar = (function(){
var foo;
return {
set: function(){
foo = 'a';
}
};
})();
bar.set();
new bar() gives? It looks like OP wants a class-like solution, not how to make private/public variables.
bar is not a function. The usage in the question shows that the OP wants something that can be used as an object, what suggests that it should also work as a constructor?
