Class NodeList

The NodeList class provides a wrapper for manipulating DOM NodeLists. NodeList properties can be accessed via the set/get methods. Use Y.all() to retrieve NodeList instances.

Constructor

NodeList ( )

Methods

addClass

void addClass ( className )
Adds a class name to each node.
Parameters:
className <String> the class name to add to the node's class attribute
Chainable: This method is chainable.

after

Object after ( type , fn , context )
Applies an event listener to each Node bound to the NodeList. The handler is called only after all on() handlers are called and the event is not prevented.
Parameters:
type <String> The event being listened for
fn <Function> The handler to call when the event fires
context <Object> The context to call the handler with. Default is the NodeList instance.
Returns: Object
Returns an event handle that can later be use to detach().

append

void append ( )
Called on each Node instance

detach

void detach ( )
Called on each Node instance

detachAll

void detachAll ( )
Called on each Node instance

each

void each ( fn , context )
Applies the given function to each Node in the NodeList.
Parameters:
fn <Function> The function to apply. It receives 3 arguments: the current node instance, the node's index, and the NodeList instance
context <Object> optional An optional context to apply the function with Default context is the current Node instance
Chainable: This method is chainable.

even

NodeList even ( )
Creates a new NodeList containing all nodes at even indices (zero-based index), including zero.
Returns: NodeList
NodeList containing the updated collection

filter

NodeList filter ( selector )
Filters the NodeList instance down to only nodes matching the given selector.
Parameters:
selector <String> The selector to filter against
Returns: NodeList
NodeList containing the updated collection

get

void get ( )
Called on each Node instance

getAttribute

string getAttribute ( name )
Allows getting attributes on DOM nodes, normalizing in some cases. This passes through to the DOM node, allowing for custom attributes.
Parameters:
name <string> The attribute name
Returns: string
The attribute value

getComputedStyle

Array getComputedStyle ( attr )
Returns an array of the computed value for each node.
Parameters:
attr <String> The style attribute to retrieve.
Returns: Array
The computed values for each node.

getStyle

Array getStyle ( attr )
Returns an array of values for each node.
Parameters:
attr <String> The style attribute to retrieve.
Returns: Array
The current values of the style property for the element.

hasClass

Array hasClass ( className )
Determines whether each node has the given className.
Parameters:
className <String> the class name to search for
Returns: Array
An array of booleans for each node bound to the NodeList.

indexOf

Int indexOf ( node )
Returns the index of the node in the NodeList instance or -1 if the node isn't found.
Parameters:
node <Y.Node || DOMNode> the node to search for
Returns: Int
the index of the node value or -1 if not found

insert

void insert ( )
Called on each Node instance

item

Node item ( index )
Retrieves the Node instance at the given index.
Parameters:
index <Number> The index of the target Node.
Returns: Node
The Node instance at the given index.

modulus

NodeList modulus ( n , r )
Creates a new NodeList containing all nodes at every n indices, where remainder n % index equals r. (zero-based index).
Parameters:
n <Int> The offset to use (return every nth node)
r <Int> An optional remainder to use with the modulus operation (defaults to zero)
Returns: NodeList
NodeList containing the updated collection

NodeList.getDOMNodes

static Array NodeList.getDOMNodes ( node )
Retrieves the DOM nodes bound to a NodeList instance
Parameters:
node <Y.NodeList> The NodeList instance
Returns: Array
The array of DOM nodes bound to the NodeList

odd

NodeList odd ( )
Creates a new NodeList containing all nodes at odd indices (zero-based index).
Returns: NodeList
NodeList containing the updated collection

on

Object on ( type , fn , context )
Applies an event listener to each Node bound to the NodeList.
Parameters:
type <String> The event being listened for
fn <Function> The handler to call when the event fires
context <Object> The context to call the handler with. Default is the NodeList instance.
Returns: Object
Returns an event handle that can later be use to detach().

prepend

void prepend ( )
Called on each Node instance

refresh

void refresh ( )
Reruns the initial query, when created using a selector query
Chainable: This method is chainable.

remove

void remove ( )
Called on each Node instance

removeClass

void removeClass ( className )
Removes a class name from each node.
Parameters:
className <String> the class name to remove from the node's class attribute
Chainable: This method is chainable.

replaceClass

void replaceClass ( oldClassName , newClassName )
Replace a class with another class for each node. If no oldClassName is present, the newClassName is simply added.
Parameters:
oldClassName <String> the class name to be replaced
newClassName <String> the class name that will be replacing the old class name
Chainable: This method is chainable.

set

void set ( )
Called on each Node instance

setAttribute

void setAttribute ( name , value )
Allows setting attributes on DOM nodes, normalizing in some cases. This passes through to the DOM node, allowing for custom attributes.
Parameters:
name <string> The attribute name
value <string> The value to set
Chainable: This method is chainable.

setContent

void setContent ( )
Called on each Node instance

setStyle

void setStyle ( attr , val )
Sets a style property on each node.
Parameters:
attr <String> The style attribute to set.
val <String|Number> The value.
Chainable: This method is chainable.

setStyles

void setStyles ( hash )
Sets multiple style properties on each node.
Parameters:
hash <Object> An object literal of property:value pairs.
