Rails spinoffs - Dec 2005 - Prototype Hash#map & #each

Hello,

I wanted to apply escape on every property of an object using the  
Hash.map method in prototype library. Check out this code:

<script type="text/javascript">

// Regular Array
var a = ["john doe", "john-Ch9RrZxMC0c@public.gmane.org",
"say hello to me"];
a.map(escape).each(function(x) {
   document.write(x + "<br />"); //nice and clean syntax
})

// Hash (not so elegant)
var h = $H({name: "john doe", email:
"john-Ch9RrZxMC0c@public.gmane.org", msg: "say hello
to me"});
function escapeHash(x) {
   x[1] = escape(x[1]);
   return x;
}

h.map(escapeHash).each(function(x) {
   document.write(x[0] + " => " + x[1] + "<br />");
});

// This way would be nice
h.map(function(element, index) {
   return escape(element)
}).each(function(element, index)) {
   document.write(index + " => " + element + "<br
/>");
}

</script>

Is Prototype able to to this in a more elegant way?


TIA
Martin
