The javascript code should be placed in the script tag

Tags are used to define client script, such as JavaScript.

Elements can either contain script statements or point to external script files through the "src" attribute.

Js code

Example 1:

JavaScript programs can be placed not only directly in HTML documents, but also in JavaScript script files. JavaScript script files are text files with a .js extension that can be edited using any text editor.

Example 2:

Create a new text file and save it as test.js. Note that the extension .js indicates that the text file is of type JavaScript.

Open the test.js file and write the following JavaScript code in it.

Alert ("Welcome")

Save the JavaScript file. It is recommended that you put the JavaScript file and the web file in the same directory.

JavaScript files cannot be run independently and need to be imported into a web page and executed through a browser. Use tags to import JavaScript files.

Insert a tag inside the tag of the html document. Define the src property and set the property value to a URL string that points to an external JavaScript file. The code is as follows:

Note: when using the < script > tag to include external JavaScript files, the default file type is Javascript. Therefore, regardless of whether the loaded file extension is .js or not, the browser will follow the JavaScript script to parse.

Save the web page document, preview it in the browser, and display it as shown in the figure.

Note: tags that define src attributes should no longer contain JavaScript code. If the code is embedded, only the external JavaScript file is downloaded and executed, and the embedded code is ignored.
