I am trying to trigger the visibility of a DIV via a button.
My code looks like this:
function myFunction() {
var moreText = document.getElementById("csrmore");
var x = document.getElementById("myDIV");
let ishidden = x.classList.contains("hidden")
if (ishidden == true) {
x.classList.remove("hidden");
x.classList.add("shown");
moreText.innerHTML = "Show less";
}
else {
x.classList.remove("shown");
x.classList.add("hidden");
moreText.innerHTML = "Show more";
}
}div {
width: 100px;
height: 100px;
}
.hidden {
display:none
}
.shown {
display:block;
}<button id="csrmore" onclick="myFunction()">
Show more
</button>
<div id="myDIV" class="hidden">
This is the triggerable content.
</div>Fiddle: https://jsfiddle.net/6zxa0Lg2/
It works fine, however since I am a JS starter, I was wondering if this is bad practice or is it a totally fine piece of code?
Thanks for every help :)
Here's another way to go about it. Make it all relative. The button is clicked and the javascript finds the content associated to that button to show/hide. This way you don't need any ID tags and you can have as many show/hide buttons as you want on the page.
document.addEventListener('DOMContentLoaded', () => {
// after the page loads...
document.querySelectorAll('.csrmore').forEach(button => {
// find all the 'show more' buttons and for each one...
button.addEventListener('click', e => {
// when someone clicks this button
let content = e.target.closest('.container').querySelector('.content');
// find the content div associated with this button
content.classList.toggle('hidden');
// toggle on or off the content
e.target.innerText = content.classList.contains('hidden') ? 'Show more' : 'Hide';
// change the text of the button
})
})
})div {
width: 100px;
height: 100px;
}
.hidden {
display: none
}<div class='container'>
<button class="csrmore">
Show more
</button>
<div class="content hidden">
This is the triggerable content.
</div>
</div>
<hr>
<div class='container'>
<button class="csrmore">
Show more
</button>
<div class="content hidden">
This is the triggerable content.
</div>
</div>This is a fine way to do this! This is not the solution I would not have come up with, but it is actually pretty clever. I would have thought to have done it by toggling TARGET.style.visibility to either "hidden" or "visible" when clicking the button. Again though, your code looks perfectly fine!
