Highlights
  • Traversing Introduction
  • Filtering methods
  • Tree Traversal methods

4
Traversing Introduction
  • Finding HTML elements based on their relation
    with other elements by moving through those
    elements section.
  • First select one elements and move through that
    selection to find out precise elements.
  • jQuery provides various of methods that allows
    users to traverse the DOM.
  • Most of the traversal methods are tree traversal
    methods.
  • Jquery provides easy moves for traversing .

5
Filtering methods
  • Returns elements which equals the specified
    criteria.
  • Filtering methods are three types, they are

6
Filtering Methods
  • First method returns the first element of the
    selected elements.
  • Syntax (document).ready(function1() ("div
    z").first() )
  • Last method returns the last element of the
    selected elements.
  • Syntax (document).ready(function1() ("div
    z").last() )
  • Eq method returns elements by a precise index
    number from the selected elements.
  • Syntax (document).ready(function1() 
    (z").eq(1) )      

7
Tree Traversal methods
  • Tree traversal methods provides easy move through
    capabilities for users to take out the precise
    elements from tree structured elements.
  • Jquery provides various types of tree traversal
    methods, they are .children(), .closest(),
    .find(), .next(), .nextAll(), .nextUntil(),
    .parent(), .offsetParent(),.parents(),
    .parentsUntil(), .prev(), .prevAll(),
    .prevUntil(), .siblings()
  • children() method take out the children of each
    element in the set of matched elements.
  • closest() method take out the first element that
    matches the selector.
  •  

8
Tree Traversal methods
  • find() method get the descendants of each element
    of the current set of matched elements.
  • nextAll() method finds out all the siblings of
    each element in the matched elements.
  • nextUntil() method gets all siblings of each
    element not only the element matched by the
    selectors.
  • offsetParent() method pick out the closest
    predecessor element.
  • parent() method find out the parent of each
    element from matched elements.

9
Tree Traversal methods
  • parents() method find out associates of each
    element from matched elements.
  • parentsUntil() method take out the ancestors of
    each element but not only the matched elements by
    selectors.
  • prev() method takes out the immediate preceding
    sibling of each element.
  • prevAll() method Get all preceding siblings of
    each element.
  • prevUntil() method gets all the preceding
    siblings of each element but not includes
    elements which matched by the selector, DOM node,
    or jQuery object.
  • siblings() method gets all the siblings of each
    element from matched elements.
