How to limit a jQuery plugin function to only some elements?

Question

I check the jQuery plugin site, which teach me how to write a basic plugin:

(function( $ ){
  $.fn.maxHeight = function() {
    var max = 0;
    this.each(functi         


        

Answer 1

You could do...

this.filter('textarea')

If you do an each() on the returned set, it will only iterate over selected textarea elements.
