Does Javascript document.getElementById function in SoloLearn editor?

Question

Please answer. I've a snippet of code with document.getElementById functioning in browser, but it seems it returns null in SoloLearn editor:

var elem = document.getElementById('para'); elem.style.color = newColor;

and in HTML body: <p id="para">a paragraph</p>

Answer 1

The problem is that the js file is probably automatically loaded in the header or beginning of the body document by SoloLearn. What you need to do is

window.onload = () => {
elem = document.getElementById(`para`)
elem.style.color = newColor
}

The more likely problem is your code itself, you should provide a link to allow a community member to help you get to the root of your problem.

btw- Check newColor
