使用jQuery中的each(data,function(){});函数

[转自：http://api.jquery.com/jQuery.each/]  

version added:
1.0

jQuery.each( collection, callback(indexInArray, valueOfElement) )

collectionThe object or array to iterate over.
callback(indexInArray, valueOfElement)The function that will be executed on every object.
The

$.each()

function is not the same as
$(selector).each(), which is used to iterate, exclusively, over a jQuery object. The

$.each()

function can be used to iterate over any collection, whether it is a map (JavaScript object) or an array. In the case of an array, the callback is
passed an array index and a corresponding array value each time. (The value can also be accessed through the

this

keyword, but Javascript will always wrap the

this

value as an

Object

even if it is a simple string or number
value.) The method returns its first argument, the object that was iterated.
