javascript - Know when a property has been set to an object using array notation -


i have object used hash table store key value pairs in javascript:

storage["key"] = "value".

i've found can use definesetter have setters each key, however, need know key names beforehand. there way of doing whenever value set way?

so example, when doing:

storage["key"] = "value";

i want handled custom method like:

custommethod : function(akey, avalue) {   //do these 2 params   // inform else this. }

thoughts/suggestions?

no, there isn't way catch property assignments. firefox 4 introduced experimental javascript proxy api allow (have proxy forward calls inner object trigger additional action when properties set) overkill here - if api stable , implemented in other browsers.
