filter
1.eq (index): Get matching element in the first N elements, from zero
2.first (): Get the first element of the matched elements
3.last (): Gets the last element of the matched elements
4.hasClass (class): checking whether the element contains a particular class
5.filter (expr): Screening and expression to match elements specified element
6.is (expr): with a collection element detects whether the expression contains at least one of the elements to meet the requirements, there Returns true, such as checking the input parent () Is not form
7.map (callback function): converting a group of elements into an array
8.has (expr): contains the elements specified conditions reservation offspring

Seek
children ([expr]): obtaining elements of all the child elements each element comprising a matched set of elements in the set
closest ([expr]): Returns the parent element of the first matching elements
find (expr): returns all elements matching expression match
next ([expr]): to obtain a matching element in the set of elements comprising each element immediately behind the sibling set
All the siblings made after the current element: nextAll ([expr])
All the elements between the acquired current element satisfying the condition elements expr: nextUntil ([expr])
offsetParent (): obtaining a first parent node of the matching element for positioning
parent (): contains all the elements to get a matching elements of the unique collection of the parent element
parents (): get a ancestor element contains all the elements of a collection of matching elements
parentUntil ([expr]): Find all of the current element of the parent element, that element until the first match
prev (): with next () method analogous
prevAll (): and nextAll () method analogous
prevUntil (): and nextUntil () method analogous
siblings (): returns a collection of element selected element peer
Series connection
add (expr): to add elements to the existing set of elements
addBack (): the elements of the collection before adding to the current set of elements
contents (): Returns all direct child elements
end (): end the current filter chain recent operation, and the matching elements of the set time before returning to the state
