This code is not displaying anything on the p tag as it suppose to do.
<!DOCTYPE html>
<html>
<body id="myBody">
<h1>HTML DOM Events</h1>
<h2>The onload Event</h2>
<p id="demo"></p>
<script>
document.getElementById("myBody").addEventListener("load", checkCookies);
function checkCookies() {
var text = "This page ";
if (navigator.cookieEnabled == true)
{
text = "Cookies are enabled.";
}
else
{
text = "Cookies are not enabled.";
}
document.getElementById("demo").innerHTML = text;
}
</script>
</body>
</html>
unlike this below
<!DOCTYPE html>
<html>
<body onload="checkCookies()">
<h1>HTML DOM Events</h1>
<h2>The onload Event</h2>
<p id="demo"></p>
<script>
function checkCookies() {
var text = "";
if (navigator.cookieEnabled == true)
{
text = "Cookies are enabled.";
}
else
{
text = "Cookies are not enabled.";
}
document.getElementById("demo").innerHTML = text;
}
</script>
</body>
</html>
I have tried it several times but cant decode the bug. Please help and resolve. Thank you
>Solution :
Change the second parameter on your addEventListener to invoke the method like so:
document.getElementById("myBody").addEventListener("load", checkCookies());
adddEventListener expects an Arrow Function Expression as it’s second argument.
Check out the MDN docs for addEventListener here
