javascript : make a new safe class constructor
- by guilin ??
sometimes we loss the new keyword when define new object,
obj = new Clazz(); //correct
obj = Clazz(); //wrong, but no syntax error, hard to debug.
I want to write a function to help me create Class and make it new safe.
var Class = function(constructor){
//when constructor
// if not call by new
return new constructor();
// else
constructor();
}
var MyClazz = Class(function(name){
this.name = name
}, SuperClazz1, SuperClass2 )
MyClazz.extend({
show: function(){console.log(this.name)}
})
obj1 = new MyClazz();
obj2 = MyClazz();
// obj1 should same as obj2
Is it possible, any exists module?
