I'm trying to show content from a div if the class active exists on a button.
<button type="button" class="tab tab-library">Library</button>
<button type="button" class="tab tab-home active">Home</button>
<button type="button" class="tab tab-settings">Settings</button>
These are the buttons I have, and the toggling of the active class works depending on the button pressed.
However I'm struggling with showing different content when I press any particular button.
<div class="home-container">
<div class="home">
Content
</div>
</div>
Only the container that has the active class should be visible/displayed.
No jQuery please as I'm still trying to learn plain JS.
this is test code, you can use querySelector , if class exit then alert ok or not, for test click the click button then alert will ok
function test() {
if (document.querySelector('.home') !== null) {
alert('ok');
} else {
alert('not');
}
}
<body>
<div class="home-container">
<div class="home">
Content
</div>
<span style="cursor: pointer; background: #0f192a;color: #00BD9B" onclick="test()">Click</span>
</div>
</body>

I have a few buttons in the HTML file code with Bulma similar like this:
<a class="button" data-target="A">Section A</a>
<a class="button" data-target="B">Section B</a>
<a class="button" data-target="C">Section C</a>
And there are a few section like this which can interact with the buttons:
<div id="A" class="contentswitch">
<article class="message">
<div class="message-header" id="h1">
<p>Section A-1</p>
</div>
<div class="message-body">
Message 1 of section A
</div>
<div class="message-header">
<p>Section A-2</p>
</div>
<div class="message-body">
Message 2 of section A
</div>
</article>
</div>
As I add code like this in the JS, it can add a class called "is-hidden" to all the div ejectment which contains "contentswitch" class.
$("a.button").on("click", function(){
$("div.contentswitch").addClass("is-hidden");
});
What can I do if I want to remove the class ("is-hidden") from specific div element, like if I click the button of Section A, then it add "is-hidden" class to all the div element contain content switch then remove it from the div element with the id "A"?
Thank you so much
You can use data-target to connect the clicked button to the div you want to show. And hide the rest of them.
Also, use button iso a tag. a tag has a specific purpose in HTML and should be used only in combination with href attribute.
const buttons = $('.button');
const contentSwitchDivs = $('.contentswitch');
buttons.on("click", function(){
const btnTarget = $(this).data('target')
const contentToShow = $(`#${btnTarget}`)
contentSwitchDivs.not(btnTarget).hide();
contentToShow.show();
});
.contentswitch {
display: none
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="button" data-target="A">Section A</button>
<button class="button" data-target="B">Section B</button>
<button class="button" data-target="C">Section C</button>
<div id="A" class="contentswitch">
A contentswitch
</div>
<div id="B" class="contentswitch">
B contentswitch
</div>
<div id="C" class="contentswitch">
C contentswitch
</div>
I just want to add class for the button after another class but it's inside of another div. Take a look at this example.
<div class="wrap">
<button class="one">Click</button>
<button class="two">Click</button>
</div>
<div class="bottom"></div>
.add-me{
color:red;
}
In here, I want to add to class button one. But it needs to be applied when bottom class appears.(This is a validation message. So I can't style directly to button one.)
I tried with this way. But it only apply for wrapper div.
$('.bottom').prev('div').first().addClass('add-me');
Here is the fiddle: https://jsfiddle.net/eqhj0vm9/2/
You have to use $('.bottom').prev().find(':first-child').addClass('add-me'); to select the prev element's first child.
$(function() {
$(".activate").click(function(){
$('.bottom').show();
$('.bottom').prev().find(':first-child').addClass('add-me');
});
});
.add-me {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="wrap">
<button class="one">Click</button>
<button class="two">Click</button>
</div>
<div class="bottom" style="display:none"> BOTTOM CLASS </div>
<br />
<button class="activate">Activate bottom class</button>
I am a beginner.
I want to display the HTML of previous element when the button is clicked.
I am able to display HTML content of button using outerHTML property. But when i use prev() function with the current object, it is showing error.
function show(currentObject) {
alert($(currentObject)[0].outerHTML);
}
above code gives the html content of the current button.
(Click) is shows as alert.
but
function show(currentObject) {
var prevObject = $(currentObject).prev();
alert($(prevObject)[0].outerHTML);
}
above code is giving me error!!
error: TypeError: $(...)[0] is undefined
Below is the html
<div class="row">
<div class="col-md-12"><a class="navbar-link" href="/somelink">linktext</a></div>
<div class="col-md-12"><p>click below button</p></div>
<div class="col-md-4"><button onclick="show(this)" class="btn btn-primary">Click</button></div>
</div>
Is there a way to do it right?
You can use .prev().html() to getting previous element html, check updated snippet below..
alert($('.currentItem').prev().html())
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item1">Previous Element</div>
<div class="item1 currentItem">Current Element</div>
If you want to use pure Javascript use previousElementSibling
document.getElementById('foo').addEventListener('click', currentObject);
function currentObject() {
alert(this.parentNode.previousElementSibling.outerHTML);
}
body {
font: 13px Verdana;
}
<div class="row">
<div class="col-md-12"><a class="navbar-link" href="/somelink">linktext</a></div>
<div class="col-md-12">
<p>click below button</p>
</div>
<div class="col-md-4"><button class="btn btn-primary" id="foo">Click</button></div>
</div>
I have two divs on a page (id's MAY and JUNE) and two buttons on the page. The page startes off by showing the May div, with the June div hidden using css display: none
I am trying to create the correct javascript that will toggle between the two of them, but (after searching on here) I can only manage to get one to work.
Codepen showing issue is https://codepen.io/billteale/pen/zwBBez
<a href="#" id="button" >MAY</a>
<a href="#" id="button" >JUNE</a>
<!-- first div, shows on page load -->
<div id="MAY">
<div style="background-color: lightgrey"><h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
<!-- second div, hidden originally -->
<div class="hidden" id="JUNE">
<div style="background-color: lightgrey"><h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
...and the current js is
var button = document.getElementById('button'); // Assumes element with id='button'
button.onclick = function() {
var div = document.getElementById('MAY');
if (div.style.display !== 'none') {
div.style.display = 'none';
}
else {
div.style.display = 'block';
}
};
Eventually I will have four or more divs to toggle between, with each button showing its relevant div, and hiding the others.
Can anybody tell me how to add to the code I have here to make this work for multiple elements?
It can be done by setting the div id's in the anchor tag's href attribute, and showing the corresponding div while hiding the rest. It can be done for any number of div's with no extra script, Just add the new div id to the new anchor tags href. You should give a common class to all the div's like month to select them all.
$("a.btn").click(function() {
var id = $(this).attr("href");
$("div.month:visible").hide();
$(id).show();
});
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
MAY
JUNE
<!-- first div, shows on page load -->
<div id="MAY" class="month">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
</div>
<!-- second div, hidden originally -->
<div class="month hidden" id="JUNE">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
</div>
First you add a "div-toggle" class to each one of the divs you want to toggle. After that, you bind click events on your buttons, firing a function which takes an identifier as argument.
The function will run through your divs and set the one that has the argument id as visible, and hide the others.
This way you can add more divs to be toggled. You just have to mark them with the "div-toggle" class, set their id's and create their respective buttons.
var divs = document.getElementsByClassName('div-toggle');
function toggle(id) {
for (var i = 0; i < divs.length; i++) {
var div = divs[i];
if (div.id == id)
div.style.display = 'block';
else
div.style.display = 'none';
}
}
<a href="#" onclick="toggle('MAY')" >MAY</a>
<a href="#" onclick="toggle('JUNE')" >JUNE</a>
<!-- first div, shows on page load -->
<div class="div-toggle" style="display:block;" id="MAY">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
</div>
<!-- second div, hidden originally -->
<div class="div-toggle" style="display:none;" id="JUNE">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
</div>
div.style.visibility = "hidden"
this will completely hide your div. I'm pretty sure this is what you are asking for
also instead of that you can make a separate function and add o'clock to div
<div onclick="nameoffunction()"></div>
the function can take in a parameter and each div on click function can have the parameter of its id
Your div were messed up! The snippet is working now with the help of jQuery.
$("#JUNE").hide();
$("#MAY").show();
$('#button-may').on("click", function() {
$("#JUNE").hide();
$("#MAY").show();
});
$('#button-june').on("click", function() {
$("#JUNE").show();
$("#MAY").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
MAY
JUNE
<!-- first div, shows on page load -->
<div id="MAY">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
</div>
<!-- second div, hidden originally -->
<div class="hidden" id="JUNE">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
</div>
I have created a script that when a button is clicked it displays all of the content beneath it and hides the other buttons content. The only problem I'm having is that I want to refactor the script so it only works if you hit the button, instead of the entire div the button sits in as it's causing some confusion. What would be the best way about this?
<div class="signup-button">
<button type="button" class="btn btn-default">Subscribe</button>
<div class="signup-form" style="display:none;">
Content
</div>
</div>
<div class="signup-button">
<button type="button" class="btn btn-default">Subscribe</button>
<div class="signup-form" style="display:none;">
Content
</div>
</div>
<div class="signup-button">
<button type="button" class="btn btn-default">Subscribe</button>
<div class="signup-form" style="display:none;">
Content
</div>
</div>
<div class="signup-button">
<button type="button" class="btn btn-default">Subscribe</button>
<div class="signup-form" style="display:none;">
Content
</div>
</div>
jQuery:
(function($) {
$(".signup-button").on('click', function() {
$(".signup-button").not(this).find(".signup-form").hide();
$(this).find(".signup-form").toggle("slow");
});
})(jQuery);
JSFiddle: https://jsfiddle.net/v6bmphct/3/
One option would be to attach the event listener directly to the descendant button element. In doing so, the click event isn't triggered when clicking on the other content. You would also have to change instances of $(this) to $(this).parent() or $(this).closest('.signup-button').
Updated Example
$(".signup-button .btn").on('click', function(e) {
$(this).parent().find(".signup-form").toggle("slow");
$(".signup-button").not($(this).parent()).find(".signup-form").hide();
});
Alternatively, since event.target is a reference to the clicked element, you could also just check to see if event.target is the button element by using the .is() method:
Updated Example
$(".signup-button").on('click', function(e) {
if ($(e.target).is('.btn')) {
$(this).find(".signup-form").toggle("slow");
$(".signup-button").not(this).find(".signup-form").hide();
}
});
Check this out:
(function($) {
$(".signup-button").find('button').on('click', function() {
$(this).siblings(".signup-form").toggle("slow");
$(".signup-button").not(this.closest(".signup-button")).find(".signup-form").hide();
});
})(jQuery);
