Today, Xiaobian will share with you the relevant knowledge points about what the steps of javascript installation are. The content is detailed and the logic is clear. I believe that most people still know this knowledge too well, so I share this article for your reference. I hope you will gain something after reading this article. Let's take a look at it together.
First, download the installation package
First, you need to download the installation package of JavaScript. JavaScript is an explanatory programming language. You can write code directly with a text editor, save it as a. js file, and then embed it in an HTML file without compilation. Therefore, you don't need to install a JavaScript compiler or interpreter separately.
However, in order to facilitate development, many web development tools will be equipped with JavaScript debuggers or other useful tools. Generally speaking, these tools will bring their own JavaScript installation packages. So, if you are using a web development tool, you usually don't need to download an additional JavaScript installation package.
If you want to download the installation package of JavaScript separately, you can go to the official website to download the stable version of JavaScript. The official website of JavaScript is https://www.javascript.com/. You can visit this website through search engines.
When you arrive at the official website of JavaScript, you will find that the installation package of JavaScript is not an independent file, but a piece of JavaScript code embedded in an HTML page. If you want to download this code, you need to choose the option of downloading or saving the page and save the page as an HTML file.
Second, embedding HTML pages
If you have downloaded the installation package of JavaScript, you need to embed this code into your HTML page. JavaScript is usually written in the tags of HTML files. The following is an example:
<html>
<head>
<script type="text/JavaScript">
//Here is your JavaScript code
</script>
</head>
<body>
<-- This is the main content of the HTML page -->
</body>
</html>
In this example, you need to insert your JavaScript code between the<script>and</script>tags. Of course, you can also save the JavaScript code as a separate. js file and link it in the<head>tag in the following way:
<html>
<head>
<script type="text/JavaScript" src="your script. js"></script>
</head>
<body>
<-- This is the main content of the HTML page -->
</body>
</html>
Third,testing
After completing the above steps, you can test your JavaScript code. You can open an HTML file in a web browser and view the JavaScript output in the browser's console.
