function or var function ? part #2
I did an error talking about difference using function, var function and (function), because as Matteo said in my last post I didn't explain perfeclty the difference from an anonymous function and a simple reference variable.
Here You can view an example, probably better than every word:
So, an anonymous function has some limit, as I said on my old post but if You need a simple, tiny function that you're not using as class, You could declare anonymous function even inside a for loop
but if You need a class or a more complex function I suggest to use the "old classic" way:
That's all, You should remember that first example doesn't work,obviously, on Explorer, try them with other standard compilant browser (FireFox, Opera, Safari, Konqueror ... etc)
Here You can view an example, probably better than every word:
var // temporary scope variable declaration
myfunc // variable name (as function referer)
=
function(){}; // anonymous function
alert(myfunc.name);
// empty string because myfunc
// is a reference of an
// anonymous function
// ---------------------------- //
function // temporary scope function declaration
myotherfunc(){};// "the" myotherfunc function
alert(myotherfunc.name);
// string "myotherfunc" because
// myotherfunc is not a reference
// but exactly a function
So, an anonymous function has some limit, as I said on my old post but if You need a simple, tiny function that you're not using as class, You could declare anonymous function even inside a for loop
for(var f = function(){}, a = [1,2,3], b = a.length; b > 0; b--)
// do stuff
but if You need a class or a more complex function I suggest to use the "old classic" way:
function f(){
// do stuff
}
That's all, You should remember that first example doesn't work,
