I'm looking for backward reference to objects "parent" information.
Once constructor are called is there any ability to get reference to
the caller context inside this constructor ?
An sample tells much more than simple words:
var firstClass = function(){
// How to detect, which object invoked this constructor - firstRunner
or secondRunner
parent.firstRunnerMethod();
parent.secondRunnerMethod();
}
var secondClass = Class.create({
initialize: function() {
// How to detect, which object invoked this constructor -
firstRunner or secondRunner ?
parent.firstRunnerMethod();
parent.secondRunnerMethod();
}
});
var firstRunner = function(){
var firstObject = new firstClass();
var secondObject = new secondClass();
this.firstRunnerMethod = function() {};
}
var secondRunner = function(){
var firstObject = new firstClass();
var secondObject = new secondClass();
this.secondRunnerMethod = function() {};
}
I can solve this by adding 'this' reference as argument to object
constructor.
var firstObject = new firstClass(this);
But this solution seems too coarse. Is there any other natural way ?
Thanks in advance !
