The core of this post is; how to call the function within the variable that has been already declared at the top.
Note: JS interacts to HTML. It reads the HTML document, then gives some change to it.
<!DOCTYPE html>
<html>
<head>
<title>How to call function within the variable?</title>
<meta charset="UTF-8" />
</head>
<body>
<div class="world">
<h2>Hello, World!</h2>
</div>
<script src="src/index.js"></script>
</body>
</html>const greetingWord = document.querySelector(".world:first-child h2");
const wrapperTrigger = {
// function functionName() {
greetingWord.innerText = "example one to display"
}
functionName: function() {
greetingWord.innerText = "example one to display"
},
functionNameTwo: function() {
greetingWord.innerText = "nothing different"
}
};
// greetingWord.addEventListener("fullscreenchange", functionName);
greetingWord.addEventListener("fullscreenchange", wrapperTrigger.functionName);
greetingWord.addEventListener("blur", wrapperTrigger.functionNameTwo);Reference: MDN
