jQuery | Traversing

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"
           });

           $("p").has("span").css(
           "background-color", "indigo");

       });

Why do I have to run “composer dump-autoload” command to make migrations work in laravel?

Basically, because Composer can't see the migration files you are creating, you are having to run the dump-autoload command which won't download anything new, but looks for all of the classes it needs to include again. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php), and this is why your migration is working after you run that command.
How to fix it (possibly) You need to add some extra information to your composer.json file.

"autoload": {
    "classmap": [
        "PATH TO YOUR MIGRATIONS FOLDER"
    ],
}

You need to add the path to your migrations folder to the classmap array. Then run the following three commands...

php artisan clear-compiled 
composer dump-autoload
php artisan optimize

This will clear the current compiled files, update the classes it needs and then write them back out so you don't have to do it again.
Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticable).
