This is a simple drop-down menu with input in HTML and pure javascript (no JQuery). I don't want to use the pre-defined HTML list with option tags because i need scroll bars, styling etc.
I hide the list onblur but this event gets triggered before the click on the items list. So the result is that I cant click on the items of the drop-down menu because the list gets hidden before hand.
This is the code:
function showList(){
elem = document.getElementById("list");
elem.className = "unhidden";
}
function hideList(){
elem = document.getElementById("list");
elem.className = "hidden";
}
function showSuccess(){
elem = document.getElementById("successDiv");
elem.innerHTML = "code successful!";
}
.hidden { display: none; }
.unhidden { display: block; }
<html>
<head>
</head>
<body>
<input onfocus="showList();" onblur="hideList();"/>
<div id="list" class="hidden">
click for success
</div>
<div id="successDiv">
</div>
</body>
</html>
The easiest solution is to add a small delay with setTimeout before hiding the element. In the example below i wait a 250 milliseconds before removing the class.
function showList(){
elem = document.getElementById("list");
elem.className = "unhidden";
}
function hideList(){
setTimeout(function() {
elem = document.getElementById("list");
elem.className = "hidden";
}, 250); // Wait 250 milliseconds
}
function showSuccess(){
elem = document.getElementById("successDiv");
elem.innerHTML = "code successful!";
}
.hidden { display: none; }
.unhidden { display: block; }
<html>
<head>
</head>
<body>
<input onfocus="showList();" onblur="hideList();"/>
<div id="list" class="hidden">
click for success
</div>
<div id="successDiv">
</div>
</body>
</html>
EDIT: More robust solution
You can look at the events relatedTarget and if it is inside the list dont close it before clicking on it.
const input = document.querySelector("#input");
const list = document.querySelector("#list");
const listItems = document.querySelectorAll("#list a");
const success = document.querySelector("#successDiv");
input.addEventListener("focus", showList);
input.addEventListener("blur", hideList);
for(const listItem of listItems) {
listItem.addEventListener("click", showSuccess);
}
function showList() {
list.classList.remove("hidden");
}
function hideList(event) {
if(event.relatedTarget?.parentNode !== list) {
list.classList.add("hidden");
}
}
function showSuccess(event) {
success.innerHTML = "code successful!";
// Remove line to keep list open
hideList(event);
}
#list {
display: flex;
flex-direction: column;
}
#list.hidden { display: none; }
<input id="input" />
<div id="list" class="hidden">
click for success
click for more success
click for even more success
</div>
<div id="successDiv">
</div>
I am trying to create a testimonial section on a wordpress site where there is an "expand" button to show the full testimonial quote. I want the text in the button to change to "collapse" after it is clicked. I also need to add a class to the div wraper so I can implement custom css styling when the button is active. I need this pasted three times. The problem is it fails after the first testimonial.
I have this working with the code below, with it duplicated three times (for three different testimonials) and it works on a basic html document. But when I implement it in a wordpress site by pasting the code, only the first testimonial totally works. The other two do show/hide my inner div element, but they won't insert the .active class or change the text of the button to "collapse"
Both of the second testimonials give a
"Uncaught TypeError: Cannot set property 'innerHTML' of null" in the console.
So for example, here are two out of three of my testimonials I want to show. I have to change the ID's on them to avoid the javascript conflict.
function showhide() {
var content = document.getElementById('hidden-content');
var wrap = document.getElementById('testimonial-wrap');
var btn = document.getElementById('button1');
if (content.style.display === 'none') {
content.style.display = 'block';
wrap.style.background = 'grey';
btn.innerHTML = 'COLLAPSE';
wrap.classList.add('active');
} else {
content.style.display = 'none';
wrap.style.background = 'white';
btn.innerHTML = 'EXPAND';
wrap.classList.remove('active');
}
}
function showhide2() {
var content2 = document.getElementById('hidden-content2');
var wrap2 = document.getElementById('testimonial-wrap2');
var btn2 = document.getElementById('button2');
if (content2.style.display === 'none') {
content2.style.display = 'block';
wrap2.style.background = 'grey';
btn2.innerHTML = 'COLLAPSE';
wrap2.classList.add('active');
} else {
content2.style.display = 'none';
wrap2.style.background = 'white';
btn2.innerHTML = 'EXPAND';
wrap2.classList.remove('active');
}
}
<div id="testimonial-wrap" style="background-color: white;">
<div id="testimonial">
above testimonial content
<div id="hidden-content" style="display: none;">
<p>"hidden content”</p>
</div>
<button id="button1" onclick="showhide()">EXPAND</button>
</div>
</div>
<div id="testimonial-wrap2" style="background-color: white;">
<div id="testimonial">
above testimonial content
<div id="hidden-content2" style="display: none;">
<p>"hidden content.”</p>
</div>
<button id="button2" onclick="showhide2()">EXPAND</button>
</div>
</div>
I think this is what you're looking for. You can do it much easier with jQuery & a small amout of code.
I didn't use display: none as I want to add the transition to the action. (transition won't work with display: none)
$(document).ready(function() {
$(".toggle-button").on("click", function() {
$(this).closest(".testimonial-wrap").toggleClass("active");
});
});
.testimonial-wrap {
background-color: #C1C1C1;
padding: 5px;
margin-bottom: 10px;
}
.testimonial-wrap.active {
background-color: #0095FF
}
.hidden-content {
height: 0px;
visibility: hidden;
transition: all 0.5s ease-out;
}
.active .hidden-content {
height: 100px;
visibility: visible;
transition: all 0.5s ease-in;
background-color: rgba(0, 0, 0, 0.5);
}
button {
display: inline-block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="testimonial-wrap">
<div id="testimonial">
<p>above testimonial content</p>
<div class="hidden-content">
<p>"hidden content”</p>
</div>
<button id="button1" class="toggle-button">EXPAND</button>
</div>
</div>
<div class="testimonial-wrap">
<div id="testimonial">
<p>above testimonial content</p>
<div class="hidden-content">
<p>"hidden content.”</p>
</div>
<button id="button2" class="toggle-button">EXPAND</button>
</div>
</div>
Basically I have 2 divs both with different contents inside and I'd like to toggle between them with a button.
I have here my 2 divs with class "step1Content" and "step2Content" respectively.
<div class = 'step1Content'> Content1 </div>
<div class = 'step2Content'> AnotherContent </div>
I gave step1Content the style display: block.
.step1Content { display: block; }
I gave step2Content the style display: none.
.step2Content { display: none; }
I have a button that would toggle between these 2 to show or hide.
<button onclick = 'step2()'>2. Taskeros and Prices</button>
And my javascript function:
function step2(){
document.getElementByClassName('step1Content').style.display = 'none';
document.getElementByClassName('step2Content').style.display = 'block';
}
You'd think the results would be a okay right? Nope, when I click the button it does literally nothing. I have no idea why, any help with this?
Keep in mind that
getElementsByClassName
will return a collection of all elements in the document with the specified class name, as a NodeList object.
You can either use getElementById or querySelector
Here's a working solution. Hope it helps!
function step2(){
if(document.querySelector('.step1Content').style.display === "none"){
document.querySelector('.step2Content').style.display = 'none';
document.querySelector('.step1Content').style.display = 'block';
}else{
document.querySelector('.step1Content').style.display = 'none';
document.querySelector('.step2Content').style.display = 'block';
}
}
.step1Content { display: block; }
.step2Content { display: none; }
<button onclick = 'step2()'>2. Taskeros and Prices</button>
<div class= 'step1Content'> Content1 </div>
<div class = 'step2Content'> AnotherContent </div>
The function is getElementsByClassName not getElementByClassName and it returns array-like collection of elements. so you need to use index 0 here for the first element.
function step2(){
var element=document.getElementsByClassName('step1Content');
element[0].style.display = (element[0].style.display ==='none') ? 'block' : 'none';
var element1= document.getElementsByClassName('step2Content');
element1[0].style.display = (element1[0].style.display ==='block') ? 'none' : 'block';
}
.step1Content { display: block; }
.step2Content { display: none; }
<div class = 'step1Content'> Content1 </div>
<div class = 'step2Content'> AnotherContent </div>
<button onclick = 'step2()'>2. Taskeros and Prices</button>
If you want to toggle visibility of div then you can use j-query toggle function.
Please read http://api.jquery.com/toggle/
$("button").click(function(){
$("#shay").toggle();
});
For Toggling two div -
CSS - .show { display: block; } .hide { display: none; }
$("button").click(function(){
$('#div1').toggle();
$('#div2').toggle();
});
</script>
<body>
<div class="hide" id="div1">Hi Div1</div>
<div class="show" id="div2">Hi Div2</div>
<button>Click me</button>
You can use Array.prototype.reverse() to toggle display of div elements
.step1Content {
display: block;
}
.step2Content {
display: none;
}
<button onclick='step2()'>2. Taskeros and Prices</button>
<div class='step1Content'>Content1</div>
<div class='step2Content'>AnotherContent</div>
<script>
var divs = Array.from(document.querySelectorAll("div[class^=step]"));
function step2() {
divs[0].style.display = "none";
divs[1].style.display = "block";
divs.reverse();
}
</script>
I'm currently using this code:
:javascript
function showstuff(content#{g.id}){
document.getElementById(content#{g.id}).style.display="block";
}
function hidestuff(content#{g.id}){
document.getElementById(content#{g.id}).style.display="none";
}
%div{ :id => "#{g.id}"}
%h3 #{g.title}
%p
#{g.excerpt}
%a{:id => "more#{g.id}",:onclick => "showstuff('content#{g.id}')"} Read More
%div{ :id => "content#{g.id}", :style => "display:none;"}
%p #{g.content}
%a{ :onclick => "hidestuff('content#{g.id}')"} Show Less
Which shows the bottom div once the first link (read more) is clicked, then hides it again when the second link (show less) is clicked. I want the first link to disappear once it's been clicked. So when the bottom div is visible, the read more link is not.
Maybe this will help you.
HTML
<div id="main" class="hide">
<a id="more" onclick="showhide();">Read More</a>
<div id="content">
<p>div content</p>
<a id="less" onclick="showhide();">Show Less</a>
</div>
</div>
CSS
#main a { cursor: pointer; } /* without href attribute there's no pointer */
#content { background: lightgray; } /* just for display purposes */
#main.hide #more { display: inline; }
#main.hide #content { display: none; }
#main.show #more { display: none; }
#main.show #content { display: block; }
JAVASCRIPT
function showhide() {
main_div = document.getElementById('main');
if (main_div.className == 'hide')
main_div.className = 'show';
else
main_div.className = 'hide';
}
I am having trouble figuring this out. After a user clicks Link1 I would like it to close when Link2 has been clicked using Javascript. I have seen an example or two with this working in jquery, but I already have a tone of code written using this method, so I would prefer to to have to start all over.Thanks everyone!
HTML...
<style>
.hidden { display: none; }
.visible { display: block; }
</style>
</head>
<body>
<div id="col2">
Link 1
<div id="contentONE" class="hidden">
<h3>contentONE</h3>
<ul>
<li>Content1.1</li>
<li>Content1.2</li>
</ul>
</div>
</div>
<div id="col2">
Link 2
<div id="contentTWO" class="hidden">
<h3>contentTWO</h3>
<ul>
<li>Content2.1</li>
<li>Content2.2</li>
</ul>
</div>
</div>
<script type="text/javascript">
function unhide(divID) {
var item = document.getElementById(divID);
if (item) {
item.className=(item.className=='hidden')?'unhidden':'hidden';
}
}
</script>
</body>
Try something like this:
var collapsables = document.getElementsByClassName('collapsable');
function unhide(divID) {
// Hide previous
for (var i = 0; i < collapsables.length; i++) {
collapsables[i].className = 'collapsable hidden';
}
// Show new
var item = document.getElementById(divID);
if (item) {
item.className = 'collapsable';
}
}
