One thing that most JavaScript writers do now, which is a good practice, is they create namespaces for their functions and variables. The following is a definition for a function that can be used to easily create namespaces of any depth:
namespace = (function(global) {
return function() {
for(var ns, obj, arr, j, i = 0; arr = arguments[i++];) {
for(obj = global, arr = arr.split("."), j = 0; ns = arr[j++]; obj = obj[ns]) {
if(obj[ns] == null) {
obj[ns] = {};
}
}
}
};
})(this);
I have to admit, this idea is not originally mine (it came from here), but the code is. The following is an example use of this handy function:
namespace("jPaq.Event", "jPaq.Color");
Who knows, this simple, yet powerful function may appear in the next version of jPaq!
