Cannot call Dom object

[dbawel]

Hello,

I've tried every location and jquery syntax for hours, and I still get an error: Uncaught TypeError: Cannot read property 'addEventListener' of null at main2.js:47. It's simply not finding the ID of the variable I've set. Any help is appriciated. It's 3am, so I'm sure I'll feel stupid in the morning.

Loading the script in the head element will call the javascript before the DOM war generated. hence - the dom elements are null.

if you use jquery, you can wrap it in a DOM-Ready function:

$(function() {

// code goes here

});

but you can simply add the javascript at the bottom of the body tag, and it will be executed after the dom was loaded (if you dont create the DOM dynamically)

Thanks so much for your help. For now I have my JS in my HTML file - not ideal, but keeps me working.

I tried every which way, but no luck no matter what I try.:

Any thoughts.

seems like the error is gone after moving the code to the body tag

OK, I knew if I just waited until morning, the answer would be there. 

Simple:

window.onload = function () {

};

And yes I do feel stupid...?

great

that's exactly like 

 

$(function() {

// code goes here

});

if you have jquery integrated. but it doesnt seem like you really need jquery at all
