$H() is prototype's Hash creator.
http://www.sergiopereira.com/articles/prototype.js.html#Reference.Hash
Here is the implementation:
http://dev.rubyonrails.org/browser/spinoffs/prototype/src/hash.js?rev=3429
Since jQuery doesn't touch Javascript's native Object the way prototype
does, you could easily use a bare object for this sort of thing.
var a = {
a1: ["1", "2"],
a2: ["3", "4"],
};
for ( var n in a ) {
var v = a[n];
}
Or you could use a wrapper, something like this--incomplete and untested:
$H = function (obj) {
var nh = {};
nh.constructor = $H;
nh.merge(obj);
return nh;
};
$H.prototype.each = function(f) {
for ( var i in this )
if typeof(this[i]) != "function" ) f({key: i, value: this[i]});
};
$H.prototype.keys = function() {
var k = [];
for ( var i in this )
if typeof(this[i]) != "function" ) k.push(i);
return k;
};
$H.prototype.values = function() {
var v = [];
for ( var i in this )
if typeof(this[i]) != "function" ) v.push(this[i]);
return v;
};
$H.prototype.merge = function(h) {
var nh = $H(h);
this.each(function(e){
if typeof(this[i]) != "function" )
nh[e.key]=e.value;
});
return nh;
};
