How to include a JavaScript file in another JavaScript file ?

This explanation will become more clear when we are building our AJAX project because AJAX projects require a web server to function. For example, let’s just say that the main.js file is hosted on the assets directory of the usablewp.com website. Currently, the browser-supported file extension for the Javascript files is .js. You’ve now linked to CSS and JavaScript files within an HTML document. If script2 requires script1, this really is the absolute easiest way to do something like this.

A JavaScript application, for example, cannot be run unless HTML or HTML code is used to execute it. You can use JavaScript in various ways on a web page, including alerting, picture galleries, DOM manipulation, data validation, and much more. You have only a few seconds to capture and maintain the interest of your viewers. One of the most significant ways to accomplish this is by creating a visually appealing and responsive website.

How to add JavaScript to HTML

I’m very surprised no-one has brought this up, as it’s the most obvious and simplest answer that will apply in nearly every single case. I had to use a variable (myVar1) defined in one JavaScript file (myvariables.js) in another JavaScript file (main.js). This tutorial will go over how to incorporate JavaScript into your web files, both inline into an HTML document and as a separate file. When working with files for the web, JavaScript needs to be loaded and run alongside HTML markup. This can be done either inline within an HTML document or in a separate file that the browser will download alongside the HTML document.

You basically add your exports to an object which is called module.exports. You then can access this object via a require(‘modulePath’). Important here is to realize that these modules are being cached, so if you require() a certain module twice it will return the already created module. Although these answers are great, there is a simple “solution” that has been around since script loading existed, and it will cover 99.999% of most people’s use cases. Just include the script you need before the script that requires it. For most projects it does not take long to determine which scripts are needed and in what order.

Hyperlinks are one of the most exciting innovations the Web has to offer. They’ve been a feature of the Web since the beginning, and are what makes the Web a web. Hyperlinks allow us to link documents to other documents or resources, link to specific parts of documents, or make apps available at a web address. Almost any web content can be converted to a link so that when clicked or otherwise activated the web browser goes to another web address (URL). The module.exports/require system old method of importing modules is still used in Node.js. In web browsers, an absolute file path is a full path (full URL) for the file involving the HTTP protocol.

  • Inside the root, we have an index.html file and a contacts.html.
  • For example, let’s just say that the main.js file is hosted on the assets directory of the usablewp.com website.
  • This would point to a file named ‘script.js’ that is in the same directory as the .html file.
  • The second index.html would perhaps be the main landing page for project-related information.

The rel attribute defines the relationship between the resource and the HTML document. Notice that the element is an empty element, so it does not need a closing tag. Mixture outputs this as scripts-global.js and also as a minified version (scripts-global.min.js). The @import syntax for achieving CSS-like JavaScript importing is possible using a tool such as Mixture via their special .mix file type (see here).

There are other ways for JavaScript to include external JavaScript contents in browsers that do not require preprocessing. But since 2015 (ES6), JavaScript has had the ES6 modules standard to import modules in Node.js, which is also supported by most modern browsers. In addition to the email address, you can provide other information. In fact, any standard mail header fields can be added to the mailto URL you provide.

As one of the core technologies of the web alongside HTML and CSS, JavaScript is used to make webpages interactive and to build web apps. Modern web browsers, which adhere to common display standards, support JavaScript through built-in engines without the need for additional plugins. Returns the name of the file referenced by the File object. Returns the last modified Date of the file referenced by the File object. See Using files from web applications for more information and examples.

Use clear link wording

This jumps up one directory level then into a ‘public’ directory then to a ‘js’ directory and then to the ‘script.js’ file. You could add a script tag with the script URL into the HTML. To avoid the overhead of jQuery, this is an ideal solution.

There are some best practices to follow when writing links. An absolute URL will always point to the same location, no matter where it’s used. Create an HTML document using your local code editor and our getting started template. A user programming language such as JavaScript, sometimes known as JS, is commonly used during website designing to build dynamic and engaging websites.

After linking the file, write the Javascript code inside the javascript file.

Be sure to save your work any time you add code to your files. In the next two sections, we will go over what you need to add to your HTML document in order to link to your CSS and JavaScript. I’ve found it’s more reliable to just write the script tags in a PHP include. You only have to write it once and that’s just as much work as calling the plugin using JavaScript. File objects are generally retrieved from a FileList object returned as a result of a user selecting files using the element, or from a drag and drop operation’s DataTransfer object.

You can add script tags in your HTML document, ideally inside the which points to your javascript files. Load the jQuery before your script files if you want how to connect js to html to use jQuery from your script. You can also use src attribute in bottom script tag to include you script file instead of putting direct js code like above.

Another attribute you may want to add to your links is title. The title contains additional information about the link, such as which kind of information the page contains, or things to be aware of on the website. Hyperlinks are really important — they are what makes the Web a web. This article shows the syntax required to make a link, and discusses link best practices.
