Creating functions dynamically in JS

by

Well, you could use Function constructor, like in this example:

var f = new Function('name', 'return alert("hello, " + name + "!");');
f('erick');

This way you’re defining a new function with arguments and body and assigning it to a variable f. You could use a hashset and store many functions:

var fs = [];
fs['f1'] = new Function('name', 'return alert("hello, " + name + "!");');
fs['f1']('erick');

Loading xml depends if it is running on browser or server.
