Magento How to add javascript file from layout

In this tutorial we will describe how to add javascript file from layout in Magento. We have just three steps, so let's folow them and in a couple of minutes, our Magento project will run a custom javascript file.

Step 1: Create Layout File

Magento 1

File path: skin/design/frontend/MageCheck/MCTheme/layout/local.xml


<?xml version='1.0'?>

<layout version='0.1.0'>
   <catalog_product_view>
       <reference name='root'>
           <reference name='head'>
               <action method='addItem'>
                   <type>skin_js</type>
                   <name>js/customjs.js</name>
               </action>
           </reference>
       </reference>
   </catalog_product_view>
</layout>

Magento 2

File path: app/code/MageCheck/Seasons/view/frontend/ magecheck_seasons_index_index.xml


<?xml version='1.0'?>

<page xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' layout='1column' xsi:noNamespaceSchemaLocation='../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd'>
    <head>
        <link src='MageCheck_Seasons::customjs.js'/>
    </head>
    <referenceBlock name='content'>
        <block template='content.phtml' class='MageCheck\Seasons\Block\Main' name='magecheck_seasons_block_main' />
    </referenceBlock>
</page>

Step 2: Create Js File

Magento 1

File path: skin/design/frontend/MageCheck/MCTheme/js/customjs.js


alert('Hello MageCheck!');

Magento 2

File path: app/code/MageCheck/Seasons/view/frontend/web/customjs.js


alert('Hello MageCheck!');

Step 3: Flush Cache

Magento 2

The last thing you have to do is to clean and flush your magento cache:

php bin/magento cache:clean

php bin/magento cache:flush

This is the simplest method to add javascript file from layout in Magento!
