Programing Coderfunda September 22, 2020 Jquery No comments

In jQuery, traversing means moving through or over the HTML elements to find, filter or select a particular or entire element.
Based on the traversing purposes following methods are Categorized as follows:

Tree Traversing:

Ancestors:

parent()
it gives parent element of specified selector
Syntax:
```
$(selector).parent();
```
parents()
it gives all ancestor elements of the specified selector.
Syntax:

```
$(selector).parents();
```

parentsUntil()
it gives all ancestor elements between specified selector and arguments.
Syntax:

$(selector).parentsUntil(selector, filter element)

$(selector).parentsUntil(element, filter element)

offsetParent()
it gives the first positioned parent element of specified selector.
Syntax:
```
$(selector).offsetParent();
```

closest()
it gives the first ancestor of the specified selector.
Syntax:

$(selector).closest(selector);

$(selector).closest(selector, context);

$(selector).closest(selection);

$(selector).closest(element);

Descendants:

children()
it gives the children of each selected elements, optionally filtered by a selector.
Syntax:
```
$(selector).children();
```
find()
it gives descendant elements of specified elements, filtered by a selector, jQuery object, or element.
Syntax:
```
$(selector).find('selector to find');
```

Siblings:

siblings()
it gives all siblings of the specified selector.
Syntax:

```
$(selector).siblings();
```
next()
it gives the next sibling element of the specified selector.
Syntax:
```
$(selector).next();
```
nextAll()
it gives all next sibling elements of the specified selector.
Syntax:
```
$(selector).nextAll();
```
nextUntil()
it gives all next sibling elements between specified selector and arguments.
Syntax:
```
$(selector).nextUntil();
```
prev()
it gives the previous sibling element of the specified selector.
Syntax:
```
$(selector).prev(selector);
```
```
$(selector).prev()
```

prevAll()
it gives all previous sibling elements of the specified selector.
Syntax:

$(selector).prevAll(selector, filter element)

$(selector).prevAll(element, filter element)

prevUntil()
it gives all previous sibling elements between specified selector and arguments.
Syntax:
```
$(selector).prevUntil(selector, filter element)
```
```
$(selector).prevUntil(element, filter element)
```

Filtering

first()
it gives the first element of the specified selector.
Syntax:
```
$(selector).first();
```
last()
it gives the last element of the specified selector.
Syntax:
```
$(selector).last();
```
eq()
it gives an element with a specific index number of the specified selector.
Syntax:
- ```
$(selector).eq(index);
```
```
$(selector).eq( indexFromEnd );
```
- filter()
  it remove/detect an elements that are matched with specified selector.
  Syntax:
```
$(selector).is(selector)
```
```
$(selector).is(function)
```
```
$(selector).is(selection)
```
```
$(selector).is(elements)
```
- has()
  it gives all elements that have one or more elements within, that are matched with specified selector.
  Syntax:
```
$(selector).has(selector);
```
- is()
  it checks if one of the specified selector is matched with arguments.
  Syntax:
```
.is( selector )
```
```
.is( function )
```
```
.is( selection )
```
```
.is( elements )
```
- map()
  Pass each element in the current matched set through a function, producing a new jQuery object containing the return values
  Syntax:
```
.map( callback )
```
- slice()
  it selects a subset of specified selector based on its argument index or by start and stop value.
  Syntax:
```
$(selector).slice(start, end );
```
```
$(selector).slice(start);
```
Miscellaneous Traversing
add()
it add all elements to set of matched elements to manipulate them at the same time.
Syntax:
```
$(selector).add(selector to add);
```
addBack()
it add the previous set of elements on the stack to the current set, optionally filtered by a selector.
Syntax:
```
$(selector).addBack();
```
andSelf()
Deprecated 1.8 which is alias of addBack().
Syntax:
```
$(selector).addSelf();
```
contents()
it gives all direct children, including text and comment nodes, of the specified selector.
Syntax:
```
$(selector).contents();
```
not()
it gives all elements that do not match with specified selector.
Syntax:
```
$(selector).not(selector);
```
end()
it is most recent filtering operation in the current chain and return the set of matched elements to its previous state and it doesn’t accept any arguments.
Syntax:
```
$(selector).each(callback function);
```

Collection Manipulation

each()
it iterates over the DOM elements and execute call back function

Example 1:

     <!DOCTYPE html>
<html>

<head>
    <style>
       .siblings * {
           display: block;
           border: 2px solid lightgrey;
           color: lightgrey;
           padding: 5px;
           margin: 15px;
       }
    </style>
    <script src=
"https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js">
</script>
    <script>
       $(document).ready(function() {
           $("h2").siblings().css({
               "color": "red",
               "border": "2px solid red"
           });
           $("h2").parent().css({
               "color": "green",
               "border": "2px solid blue"
           });
           $("p").first().css(
           "background-color", "yellow");
           $("p").has("span").css(
           "background-color", "indigo");

       });
    </script>
</head>

<body class="siblings">

    <div>GeeksforGeeks (parent)
       <p>GeeksforGeeks</p>
