Unable to include a JavaScript file within another JavaScript file

Currently, I am working on a project where I am utilizing Django for the backend and HTML/CSS/JS for the frontend development.

On a specific HTML page, I am including two JS files: dom_creator.js and console_page.js. My goal is to access the functionalities of dom_creator within console_page, but no matter what approach I take, I am unable to locate the correct import statement. Additionally, some of the ES6 import statements I have tried actually cause console_page.js to malfunction.

Another component in my HTML is the imported module console_module.js. In this file, I have successfully imported dom_creator.js using the following syntax:

import {function1, function2} from "./dom_creator.js"

My question is, how can I import functions from dom_creator into console_page.js, which is not a module? Despite consulting various solutions on Stack Overflow, none of them have proven effective in my case.

Answer №1

If you're encountering issues with importing JavaScript files in your HTML code, the solution may lie in adjusting the script element.

Ensure you add the attribute TYPE = "MODULE" to the script element like so:

Here's an example of how to structure your HTML code:

<script type="module" src="./myscript.js"> </script>

And here's how your JavaScript file may look:

function print(y){

    console.log(y);

}

export {print};

To successfully import the print function into another JavaScript file, follow these steps:

import {print} from "./main.js" // make sure to include .js extension

print('hello world');

// Alternatively, import all functions at once

import * as main from "./main.js" // make sure to include .js extension

// To use the latter method:

let variable = main.print('hello world');

To import a function into another file, you must first export it.

If you are using es5 (commonly used in NodeJs), you can export it as shown below:

var myfunction = function () {}

module.exports = { myfunction }

In newer versions (es6+), you can use export like this:

var myfunction = function () {}

export myfunction;
// Then you can import it like: import {myfuntion} from 'file.js';
// Or with another name: import {myfuntion as john} from 'file.js';

// Or export it as default like:
export default myfunction;
// Then you can import it like: import myfuntion from 'file.js';
// Or with any other custom name: import john from 'file.js';
