You shouldn't be doing that... it's bad practice. You should be using an
Array and looking items up by integer index - rather than using an
Object and looking items up by an index-containing name string --
because it's considerably more efficient.

 

The only time you should look up properties by name is when you don't
know at author time what name you'll be looking up.

When I do this[idOfsomethingImLookingfor]

I usually do this if I have to loop something.

So:

for (i=0; i10; i++){
var example:Object = this[myComponent + i]
//do some more stuff
}

I'm trying to do the same thing in .NET. I don't know what it's
called though so I'm having a hard time googling it.

Thanks,

Nate

That's called bad practice. The lookup method you're referring to is called
an associative array or dictionary.

I have seen and used the term bracket notation.  Don't know how common
it is.

 

Kevin, why do you allege bad practice?  What are you referring to for
that matter?

Re: [flexcoders] What's this Called?

2008-03-24 Thread Josh McDonald 
Looking things up in that method foo[bar] rather than foo.bar, is slow and
can cause runtime exceptions if you don't check foo.hasOwnProperty(bar).

You're better off having a foo.bar = Array(), and doing foo.bar[n] rather
than foo[bar + n] whenever possible.

The only time you really want to use this sort of syntax is when you're
building an assosc. array at runtime and you can't know what the key names
will be (eg, it's generated from user-input, or perhaps some framework
code).

I 2nd bad practice. It's unreadable and less efficient. I would hate to read
code where ids were named myComponent1, myComponent2, etc... It would be so
much better to just reference readable names in an indexed Array.

# var myComponents:Array = [ idFirstName, idLastName, idEmail ];
#
# for (var i=0; imyComponents.length-1; i++){
# var example:Object = this.myComponents[i];
# //do some more stuff
# }

Although, I can't think of any reason why you would want to loop through
components like that in the first place. Maybe .NET has different practices
though.

~Aaron
