I like it!
Some things I noticed:
- I manged to get a -1 count on the second textarea, mostly by typing
wildly in it
- if(typeof(nr) == "undefined") { nr = 0; } <- that line seems to define
a global variable if it isn't set yet, why not just using var nr = 0; ?
- I'd like to be able to specify the maxlength via a plugin option
instead of the attribute
- there is no need to set the "relatedElement" as an expando property,
you can just use a closure to access it from inside the keyup handler,
eg. var related = ...; $(...).keyup(function() { /* do something with
related */ });
- you don't need that ID on the counter either, instead create it as:
var counter = $(html_counter).insertBefore(this); - then you can use
"counter" instead of searching for the id and saving it as relatedElement
Hope that helps.
