Trouble arises when adding a .js script to the webpage

I'm feeling quite puzzled by this small piece of code, as it appears to be the simplest thing you'll come across today. Despite that, I can't help but seek guidance because I've been staring at it for what feels like an eternity and cannot understand why it refuses to cooperate.

index.html

<html>
<head>
<SCRIPT type="text/javascript" src="include.js"></SCRIPT>
</head>
<body onload="test()">
<p id="center"></p>
</body>
</html>

include.js

function test()
{
  document.getElementByID('center').innerHTML="testing";
}

Every time I open index in a browser window, all I get is a blank page. I even tried inserting an alert window at the beginning of the test() function and surprisingly, it did trigger. However, if I move the alert after the "testing" line, nothing happens.

Your help would be greatly appreciated.

Answer №1

Switch Out

getElementByID

for

getElementById

Make sure to check the console for any errors. Having such a tool is crucial for troubleshooting.

Answer №2

Make sure to use getElementById instead of just ID at the end!

If you press f12 in your browser, an error console will appear to assist with these basic problems.

Answer №3

Give this a shot:

When the window loads, execute the test function that replaces the content in the element with id 'center' to display "testing":
window.onload = function test() {
  document.getElementById('center').innerHTML = "testing";
}
