I believe my syntax is correct, but I do not understand why it does not work properly.

The problem is that your onload listener is not aware of middleContainer function because middleContainer is not defined on global scope.

One of the option is to just define the function on global scope.

// in page_structure.js
// middleContainer defined on module scope
function middleContainer()
 var _container_ID = "middle_container";
 ...

// middleContainer defined global scope
window.middleContainer = middleContainer;

Then <body onload="middleContainer()"> should no longer complain about middleContainer being undefined and should run the middleContainer function.

Another option is to add the onload event listener to your module. Instead you can remove the onload attribute on the <body> tag and defined the onload event as follows

// in page_structure.js
function middleContainer()
 var _container_ID = "middle_container";
 ...

// define the listener with your module scoped function to a global event listener
window.onload = middleContainer;

Npm run is used to run a command defined in package.json.

https://docs.npmjs.com/cli/run-script

You can run your script with node page_structure.js

You are misunderstanding how npm and npm run works. package.json is not a file that is used by the code YOU wrote anywhere, it is used by NPM to manage/run projects. Read more here: https://docs.npmjs.com/files/package.json

If you run the command npm init a package.json file will be created for you. You can then add a run script inside so it looks something like:


 "name" : "Some Name",
 "version" : "1.0.0",
 "scripts": 
 "start": "node page_structure.js",
 "other script": "some other bash command"

Now there is a package.json with a script called "start" defined. npm run start will now execute the command node page_structure.js which should run your file.

The problem is that your onload listener is not aware of middleContainer function because middleContainer is not defined on global scope.

One of the option is to just define the function on global scope.

// in page_structure.js
// middleContainer defined on module scope
function middleContainer()
 var _container_ID = "middle_container";
 ...

// middleContainer defined global scope
window.middleContainer = middleContainer;

Then <body onload="middleContainer()"> should no longer complain about middleContainer being undefined and should run the middleContainer function.

Another option is to add the onload event listener to your module. Instead you can remove the onload attribute on the <body> tag and defined the onload event as follows

// in page_structure.js
function middleContainer()
 var _container_ID = "middle_container";
 ...

// define the listener with your module scoped function to a global event listener
window.onload = middleContainer;

Dakota, your answer works perfectly. I will however read a bit more on in JS scoping. It's a bit tangled how the language works. Thank you very much.

Npm run is used to run a command defined in package.json.

https://docs.npmjs.com/cli/run-script

You can run your script with node page_structure.js

Petr, than you, Yes it's node not npm. My bad. I would edit the question.

If you run the command npm init a package.json file will be created for you. You can then add a run script inside so it looks something like:


 "name" : "Some Name",
 "version" : "1.0.0",
 "scripts": 
 "start": "node page_structure.js",
 "other script": "some other bash command"

Now there is a package.json with a script called "start" defined. npm run start will now execute the command node page_structure.js which should run your file.
