New to javascript trying to figure this out - javascript

So I'm trying to make multiple lights activate on button clicks and I'm not sure what I'm doing wrong here.
I thought I could make this into a function and then pass it the id name but it looks like it's not acting the way I want.
html
<div class="lights">
<div id="red"></div>
<div id="yellow"></div>
<div id="green"></div>
</div>
<div class="button">
<button id="red_button"> Red Button </button>
<button id="yellow_button">Yellow Button </button>
<button id="green_button">Green Button </button>
</div>
css
.lights{
height: 600px;
width: 200px;
background-color: black;
padding-top: 15px;
}
.button{
padding-top: 20px;
}
#red,
#yellow,
#green {
margin: 0 auto;
background-color: black;
border-radius: 50%;
width: 180px;
height: 180px;
margin-top: 10px;
}
#red.active {
background-color: red;
}
#yellow.active {
background-color: yellow;
}
#green.active {
background-color: green;
}
jquery
function click(e) {
$('#red,#yellow,#green').removeClass('active');
$('e').addClass('active');
}
$('#red_button').click(click('#red'));
$('#yellow_button').click(click('#yellow'));
$('#green_button').click(click('#green'));

A few things. I wouldn't recommend naming your function after an event, although it should still work. The issue with your code is that you're immediately calling the function, and in the function you quoted the parameter. Use this instead:
function click(e) {
$('#red,#yellow,#green').removeClass('active');
$(e).addClass('active');
}
$('#red_button').click(function () {
click('#red')
});
$('#yellow_button').click(function () {
click('#yellow')
});
$('#green_button').click(function () {
click('#green')
});
.lights {
height: 600px;
width: 200px;
background-color: black;
padding-top: 15px;
}
.button {
padding-top: 20px;
}
#red, #yellow, #green {
margin: 0 auto;
background-color: black;
border-radius: 50%;
width: 180px;
height: 180px;
margin-top: 10px;
}
#red.active {
background-color: red;
}
#yellow.active {
background-color: yellow;
}
#green.active {
background-color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="lights">
<div id="red"></div>
<div id="yellow"></div>
<div id="green"></div>
</div>
<div class="button">
<button id="red_button">Red Button</button>
<button id="yellow_button">Yellow Button</button>
<button id="green_button">Green Button</button>
</div>

Fixed: http://jsfiddle.net/0m9wos1r/4/
2 issues you need to fix:
The function call within the click call. Like so, using an anonymous function:
$('#red_button').click(function(){click('#red')});
The selector within the click function. Like so:
$(e).addClass('active');

Simple javascript click to add class not working

I am trying to add / remove a class on an element that is clicked liek this
function myFunction() {
this.classList.add("myclass");
}
#first {
height: 100px;
width: 100px;
background: yellow;
color: black;
}
.myclass {
background: red;
color: white;
}
<div id="first" onclick="myFunction(this)">
Click
<div class="second">
</div>
<div class="third">
</div>
</div>
Why is this not working?
You need to pass reference this into function too like:
function myFunction(el) {
el.classList.add("myclass");
}
#first {
height: 100px;
width: 100px;
background: yellow;
color: black;
}
.myclass {
background: red!important;
color: white!important;
}
<div id="first" onclick="myFunction(this)">
Click
<div class="second">
</div>
<div class="third">
</div>
</div>
PS. add !important into css
Pass the this to the defined function too and check the existence of the class. Try this.
function myFunction(el) {
if(!el.classList.contains("myclass")) {
el.classList.add("myclass");
console.log("added");
} else {
el.classList.remove("myclass");
console.log("removed");
}
}
#first {
height: 100px;
width: 100px;
background: yellow;
color: black;
}
.myclass {
background: red;
color: white;
}
<div id="first" onclick="myFunction(this)">
Click
<div class="second">
</div>
<div class="third">
</div>
</div>
It doesn't work because this for inline handlers works differently. You can use .call, and that works... but that's still not good.
function myFunction() {
this.classList.add("myclass");
}
#first {
height: 100px;
width: 100px;
background: yellow;
color: black;
}
.myclass {
background: red !important;
color: white;
}
<div id="first" onclick="myFunction.call(this)">
Click
<div class="second">
</div>
<div class="third">
</div>
</div>
You should avoid inline script altogether and also avoid id selectors in CSS.
Change your id selector to a class selector and change your inline handler to an event listener.
Also, stray strings like "content" are a real pain as your project grows in size. Wrap them in a <span>
const myButton = document.querySelector(".first");
myButton.addEventListener("click", ({
target
}) => target.classList.add("myclass"))
.first {
height: 100px;
width: 100px;
background: yellow;
color: black;
}
.myclass {
background: red;
color: white;
}
<div class="first">
<span>Click</span>
<div class="second"></div>
<div class="third"></div>
</div>
You are facing 2 issues :
you pass this as a parameter to the onclick event, but don't get it in the function definition (), so you can fix it like below ;
id selector is more specific than class selector, so it always take precedence. You can use a class instead of an id for first div, and then your css rule works :)
function myFunction(el) {
el.classList.add("myclass");
}
.first {
height: 100px;
width: 100px;
background: yellow;
color: black;
}
.myclass {
background-color: red;
color: white;
}
<div class="first" onclick="myFunction(this);">
Click
<div class="second">
</div>
<div class="third">
</div>
</div>

JavaScript adding classes on multiple modals

I'm kind of desperate. I'm trying to make the same modal as Behance has when you click on one of the little windows but I can't get my JavaScript to work. I'm not able to show "test2".
function modalActive(){
document.getElementsByClassName("window")[0].classList.add("modalActive")
};
function closeModal(){
document.getElementsByClassName("window")[0].classList.remove("modalActive")
};
.gallery-item {
width: 120px;
height: 120px;
border: 3px solid gray;
float: left;
margin-left: 10px;
}
.window {
display: none;
height: 500px;
width: 500px;
Background-color: gray;
z-index: 100000;
position: absolute;
margin: 0 auto;
}
.modalActive {
display: block !important;
}
<div class="gallery-item">
<button class="button" onclick="modalActive()">derp</button>
</div>
<div class="window">
<button class="close" onclick="closeModal()">×</button>
test1
</div>
<div class="gallery-item">
<button class="button" onclick="modalActive()">derp</button>
</div>
<div class="window">
<button class="close">×</button>
test2 - im not able to see this due to some error in my code/knowledge
</div>
You have to target a specific modal to open when clicking on the buttons. At the moment you are only ever finding the first modal and setting the modalActive class.
I have updated your code below to pass the modal id number when clicking on a button.
function modalActive(id){
document.getElementsByClassName("window-" + id)[0].classList.add("modalActive")
};
function closeModal(){
document.getElementsByClassName("modalActive")[0].classList.remove("modalActive")
};
.gallery-item {
width: 120px;
height: 120px;
border: 3px solid gray;
float: left;
margin-left: 10px;
}
.window {
display: none;
height: 500px;
width: 500px;
Background-color: gray;
z-index: 100000;
position: absolute;
margin: 0 auto;
}
.modalActive {
display: block !important;
}
<div class="gallery-item">
<button class="button" onclick="modalActive(1)">derp</button>
</div>
<div class="window window-1">
<button class="close" onclick="closeModal()">×</button>
test1
</div>
<div class="gallery-item">
<button class="button" onclick="modalActive(2)">derp</button>
</div>
<div class="window window-2">
<button class="close" onclick="closeModal()">×</button>
test2 - im not able to see this due to some error in my code/knowledge

JQuery hide multiple div of similar id when clicked outside

I want to hide all the div with similar id if not clicked on any of those div's. In my code it is working only for the first div since I have use index[0] to fetch the id. I want to generalize it to work for all the id.
Here is the code:
$(window).click(function(e) {
if (e.target.id != $('[id^=div_]')[0].id) {
$('[id^=div_]').hide();
}
});
div {
height: 150px;
width: 150px;
display: inline-block;
background: green;
margin: 10px;
color: #fff;
text-align: center;
line-height: 150px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="div_1">One</div>
<div id="div_2">Two</div>
<div id="div_3">Three</div>
<div id="div_4">Four</div>
FIDDLE
The simple solution here is to use a common class on all the elements. You can then use is() to determine if e.target was one of those elements and hide/show them as needed. Try this:
$(window).click(function(e) {
if (!$(e.target).is('.div')) {
$('.div').hide();
}
});
div {
height: 150px;
width: 150px;
display: inline-block;
background: green;
margin: 10px;
color: #fff;
text-align: center;
line-height: 150px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="div_1" class="div">One</div>
<div id="div_2" class="div">Two</div>
<div id="div_3" class="div">Three</div>
<div id="div_4" class="div">Four</div>
I cannot make any changes in HTML like adding classes
In that case you can check the id of the clicked element to see if it begins with div_. If not, then hide all the divs, something like this:
$(window).click(function(e) {
if (e.target.id.indexOf('div_') != 0) {
$('[id^=div_]').hide();
}
});
div {
height: 150px;
width: 150px;
display: inline-block;
background: green;
margin: 10px;
color: #fff;
text-align: center;
line-height: 150px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="div_1" class="div">One</div>
<div id="div_2" class="div">Two</div>
<div id="div_3" class="div">Three</div>
<div id="div_4" class="div">Four</div>
Hey you can use this function
if(e.target.id=="" || $('[id^=div_]').filter('#'+e.target.id).length==0){
$('[id^=div_]').hide();
}
filter function will filter the selected div in list of div whoes id starts with div
$(window).click(function(e) {
if(e.target.id=="" || $('[id^=div_]').filter('#'+e.target.id).length==0){
$('[id^=div_]').hide();
}
});
div {
height: 150px;
width: 150px;
display: inline-block;
background: green;
margin: 10px;
color: #fff;
text-align: center;
line-height: 150px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="div_1">One</div>
<div id="div_2">Two</div>
<div id="div_3">Three</div>
<div id="div_4">Four</div>

Hover in prepend() function

HTML:
<div class="Wrap">
<div class="container">
<div class="count">My Counter</div>
<div class="background"></div>
<div class="hover"></div>
</div>
</div>
<button class="AddDiv">AddDiv</button>
jQuery:
$('.AddDiv').on('click', function(){
$('.Wrap').prepend($('<div class="container"><div class="background"></div><div class="hover"></div></div>'));
});
$(".background").on("mouseover", function () {
$(".hover").fadeIn(500);
});
$(".hover").on("mouseout", function () {
$(".hover").fadeOut(200);
});
https://jsfiddle.net/mpd075s8/5/
Hello, I have problem with hover, look at the jsfiddle and click on button AddDiv and when hover on the green square hovered are all divs, but I would like that every div will be hovered separately. And hover doesn't work in new divs
Two things
You need to use delegated event for dynamic element
Use this for the reference of current element.
Try like following.
$('.AddDiv').on('click', function() {
$('.Wrap').prepend($('<div class="container"><div class="background"></div><div class="hover"></div></div>'));
});
$(".Wrap").on("mouseover", ".background", function () {
$(this).next(".hover").fadeIn(500);
});
$(".Wrap").on("mouseout", ".hover", function () {
$(this).fadeOut(200);
});
.Wrap {
width: 650px;
height: 800px;
}
.container {
position: relative;
top: 5px;
left: 5px;
width: 200px;
height: 200px;
background-color: red;
float: left;
margin-left: 5px;
margin-top: 5px;
}
.AddDiv {
position: absolute;
top: 0px;
}
.background {
width: 20px;
height: 20px;
background-color: green;
position: absolute;
left: 170px;
top: 10px;
}
.hover {
width: 200px;
height: 200px;
background-color: rgba(255, 255, 255, 0.8);
position: absolute;
z-index: 1001;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="Wrap">
<div class="container">
<div class="background">
</div>
<div class="hover">
</div>
</div>
</div>
<button class=AddDiv>AddDiv</button>
You can use $(this) jquery function
$("body").on("mouseover",".background", function () {
$(this).siblings('.hover').fadeIn(500);
});
$("body").on("mouseout",".hover", function () {
$(this).fadeOut(200);
});
