I read, with great interest, about using a button to show and hide text here. However, I have several blocks of text for which I would like a button to toggle show/hide but would prefer not to duplicate the same function several times. I would like to pass the div ID as a parameter so that multiple buttons may use the same function to show/hide the text associated with each button. I tried the following code but it does not work.
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
#myDIV {
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top: 20px;
}
</style>
</head>
<body>
<p>Click the "Try it" button to toggle between hiding and showing the DIV element:</p>
<button onclick="myFunction('myDIV')">Try it</button>
<div id="myDIV">
This is my DIV element.
</div>
<p><b>Note:</b> The element will not take up any space when the display property set to "none".</p>
<script>
function myFunction(myDiv) {
var x = document.getElementById(myDIV);
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}
}
</script>
</body>
</html>
