[ACCEPTED]-What is a jQuery Object?-definitions
A jQuery object is array-like which means 13 that it contains zero or more indexes (properties 12 which names are positive integers starting 11 with zero). Besides those indexes, a jQuery 10 object contains these properties:
lengthcontextselector
And also 9 around 140 inherited methods (which are 8 defined on the jQuery.prototype object - you can do console.dir(jQuery.prototype) to 7 get a full list... ).
Note that jQuery objects 6 do not contain (or inherit) the Array methods 5 (slice, substr, ...). If you want to execute 4 those methods on your jQuery object, use 3 call/apply.
For example, if you have 3 TEXTAREA elements 2 on the page and you do this:
var j = $('textarea');
then this j jQuery 1 object will contain these properties:
0- reference to the first TEXTAREA element1- reference to the second TEXTAREA element2- reference to the third TEXTAREA elementlength- which is3context- reference to thedocumentobjectselector- which is'textarea'- plus all those inherited methods...
the jQuery object is an object which has 7
- a length property
- numeric properties which reference the items from the select (0,1,2,3...)
- bindings to jQuery functions
- additional jQuery properties
The length and numeric properties allow 6 the object to respond like an array. You 5 can run it in a for loop or use functions like 4 map or each on it.
I would recommend using your 3 browser's debugger or Firebug and inspect 2 a jQuery object. That will teach you a 1 lot about how it is structured.
