Rails spinoffs - Nov 2005 - AW: array.each() on associative array?

Prototype.js seems to extend the standard javascript array constructor. It adds
some methods and properties.

 

If I do the for (key in array) I get additional keys that I didn’t add.

Can’t you just do this?  It’s built into javascript:


for (key in arrayname) {
            alert(key + ‘=’ + arrayname[key]);

}

Hi List!

 

Is there a way to iterate through an associative array when prototype.js is
used?

 

 

 

arrayname.each(function (i) {

       alert(i);

});

seems to work only for numeric arrays.

 

 

Thanks, Josef Stich
