changing value by button click - javascript

I am just starting with JS and I found a function which changes the quantity of ingredients on a receipt. I want to change the value by clicking only the button.
I have included jquery. The classes are formatted accordingly and these are entered with a value as a dataBase value. The function now iterates through the index and multiplies the base value by the portion input.
// Recipe calculator with jquery
function computeServing(serving) {
$('.js-recipeIngredient').each(function(index, item) {
$(item).children('span').html($(item)[0].dataset.basevalue * serving)
})
}
$('#servingInput').on('change', function() {
computeServing($(this).val())
})
$('.js-calcService').on('click', function() {
var currentServing = $('#servingInput').val()
$('#servingInput').val(currentServing)
computeServing(currentServing)
})
computeServing(4)
.Recipe-IngredientList {
width: 250px;
border: 1px solid #777;
border-radius: 3px;
padding: 5px;
margin-top: 5px;
}
.Recipe-Ingredient {
border-bottom: 1px solid black;
padding: 5px 0;
}
.Recipe-Ingredient:last-child {
border-bottom: none;
}
.Recipe-Ingredient span {
font-weight: 600;
}
<h3>Recipe</h3>
<div>
<label for="serving">Portions :</label>
<input type="number" id="servingInput" value="4">
<button id="js-calcService">Portionen</button>
<div class="Recipe-IngredientList">
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="100">Farine : <span></span>g</div>
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="2">Oeuf : <span></span></div>
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="150">Lait : <span></span>mL</div>

Can anybody give me a hint how I can make the calculation work with the button?
Thanks!

Besides you could improve the button's click function to:
$('.js-calcService').on('click', function() {
computeServing($('#servingInput').val())
});
the presented code seems to work just fine.
Another advice would be to use the "input" Event. This way you won't need any button at all:
// Recipe calculator with jquery
const $servingInput = $('#servingInput');
function computeServing(amount) {
const serving = amount ?? parseFloat($servingInput.val() || 1);
$('.js-recipeIngredient').each((i, item) => {
$(item).find('span').html(Number(item.dataset.basevalue) * serving)
});
}
$servingInput.on('input', computeServing); // Do on input
computeServing(); // Do on page load
.Recipe-IngredientList {
width: 250px;
border: 1px solid #777;
border-radius: 3px;
padding: 5px;
margin-top: 5px;
}
.Recipe-Ingredient {
border-bottom: 1px solid black;
padding: 5px 0;
}
.Recipe-Ingredient:last-child {
border-bottom: none;
}
.Recipe-Ingredient span {
font-weight: 600;
}
<label for="serving"><span>Portions:</span> <input type="number" id="servingInput" value="4"></label>
<div class="Recipe-IngredientList">
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="100">Farine: <span></span>g</div>
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="2">Oeuf: <span></span></div>
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="150">Lait: <span></span>mL</div>
<div class="Recipe-Ingredient js-recipeIngredient" data-baseValue="50">Lardon: <span></span>g</div>
</div>

jQuery contents() when used with 'iframe' , text disappears in firefox

I'm trying to make a website, somewhat similar to jsbin.com.
Here is a snap of how it looks in ...
Firefox -
ScreenShot
Chromium - ScreenShot
Take a look at code !
$(".toggleButton").hover(function() {
$(this).addClass("hightlightedButton");
}, function() {
$(this).removeClass("hightlightedButton");
});
$(".toggleButton").click(function() {
$(this).toggleClass("active");
$(this).removeClass("hightlightedButton");
});
$(".panel").height($(window).height() - $("#header").height() - 14);
$(".panel").width(($(window).width() / 2) - 5);
$("iframe").contents().find("html").html($("#htmlPanel").val());
body {

Check out exact code : 'Paste Bin'
Problem Description
As you can see in Screenshots of Firefox Browser the Hello World! is not visible in the second tab, but in Screenshots of Chromium Browser can see it (in the second half of screen).
Main Line of code (I think) which needs to edited is in <script type="text/javascript"></script> (Tag).
$("iframe").contents().find("html").html($("#htmlPanel").val());
How to get the output same in Firefox, like it's in other browsers (Chromium)?
Extra:
Solutions I tried, that are not working
iframe content disappears on Firefox (from stack-overflow)
Jquery contents() change html for iframe disappear in firefox (from stack-overflow)

Javascript file partially running

So I taught myself coding a few years ago, and got it just enough to put together a few tools for work. I recently had to migrate my site out of CodePen and onto an actual web server. Now I'm having an issue where part of my javascript is executing properly (a portion that empties all other input fields when a user enters an input field using JQuery), but the button that calculates an answer will not work. I believe the .click is not picking it up. Either way I'm not getting error messages, the button just does nothing when I press it.
When I put the code in a snippet to share with you guys, it works (just like it did in CodePen), but the exact same code on my web host does not work. I'm really at a loss here and any help would be greatly appreciated. I feel like I'm missing some small line of code that's supposed to be included in all web files.

Appended items flow outside of div

I have a simple "dice" roller, where the user can choose how many sides and how many dice based on input.
My issue is that if the user selects a large number of dice, it will force the page to scroll left in order to view the other dice.
I have tried to keep these dice within a div , even trying word-wrap: break-word; within the css, but this stacks the dice on top of eachother.
heres my code.
$(document).ready(function() {
$('#autoLoadR').click(function() {
$('#buttnLodr').html("");
if ($('#sideNum').val() < 100) {
if ($('#diceNum').val() < 20) {
for (i = 0; i < $('#diceNum').val(); i++) {
let index = i + 1;
let roll = index;
sidesAmount = $('#sideNum').val();
roll = Math.floor(Math.random() * sidesAmount) + 1;
$('#buttnLodr').append("<span id='diceBox'>" + roll + "</span>")
}
} else {
alert("Please enter a number for less than 20 for number of dice")
}
} else {
alert("Please enter a number less than 100 for number of sides")
}
});
});
body {

}
Also, some other suggestions:
you have some implicitly declared variables (i in your for loop and sidesAmount in that loop)
use const instead of let whenever you are not re-asigning a variable
why looping from 0, then add 1 and then store it to another variable. And then you overwrite that variable with Math.floor
try to avoid selecting DOM elements (event if its only single) by IDs. Always use class.

Clear data attribute on click

I have a function that copies the data attribute and gives it an active class. I need to be able to clear the active class from .copy-btn when either .close1 or .close2 is clicked.
$(document).ready(function() {
$(".copy-btn").click(function(event) {
event.preventDefault();
});
});
var clip = new Clipboard(".copy-btn");
$(".copy-btn").click(function(e) {
$.each($(".copy-btn"), function(index, value) {
if (
$(value).attr("data-text") ==
$(e.target).attr("data-text")
) {
$(value).addClass("active");
}
});
});
.btn {
width: 50px;
height: 20px;
border: 2px solid;
cursor: pointer;
}
.copy-btn {
outline: none;
cursor: pointer;
border: none;
background-color: white;
font-size: 21px;
}
.active {
border-bottom: 3px dotted green;
padding-bottom: 4px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/1.5.12/clipboard.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="copy-btn" data-text="CODE1">CODE1</p>
<p class="copy-btn" data-text="CODE2">CODE2</p>
<p class="copy-btn" data-text="CODE3">CODE3</p>
<div class="btn close1">Close 1</div>
<div class="btn close2">Close 2</div>
Just using removeClass()
$('.close1, .close2').on('click', function() {
$('.copy-btn').removeClass('active');
})

Swapping an image when a toggle has been clicked on

I have the following code where I added a plus symbol to one of my service titles. I was informed by someone that when that service is clicked on I should have a minus sign take its place to show that it can be minimized. I am unsure of how to swap out the plus sign when the description has been expanded. Does anyone have any ideas of how I could do that?
Here is a snippet. Click on one of the service names to see the description expand.
$('.service_wrapper').click(function() {
var thisDescription = $('.service_description', $(this));
// Hide all other descriptions
$('.service_description').not(thisDescription).hide();
// Toggle (show or hide) this description
thisDescription.slideToggle(500);
});
.service_wrapper {
border: 1px solid black;
margin: 15px;
width: 20%;
}
.service_list {
margin-left: 20%;
}
.service_title {
padding: 15px 12px;
margin: 0;
font-weight: bold;
font-size: 1em;
}
.service_title:hover {
background-color: gray;
color: blue;
cursor: pointer;
}
.service_description {
display: none;
padding: 8px 14px;
width: 100%;
margin-top: 10px;
font-size: .9em;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="service_list">
<div class="service_wrapper">
<div class="service_title">
<img src="http://realtorcatch.com/icons/plusSymbol.png" alt="Service" style="width:10px;height:10px;">Floors</div>
<div class="service_description">The best floors!</div>
</div>
<div class="service_wrapper">
<div class="service_title">Roofs</div>
<div class="service_description">Your roof will be perfect!</div>
</div>
<div class="service_wrapper">
<div class="service_title">Siding</div>
<div class="service_description">mmmm siding.</div>
</div>
<div class="service_wrapper">
<div class="service_title">Paint</div>
<div class="service_description">Fabulous paint!</div>
</div>
<div class="service_wrapper">
<div class="service_title">Kitchen Remodels</div>
<div class="service_description">Pretty kitchen.</div>
</div>
</div>
Here is the working example, i change a little de html and Js
$('.service_wrapper').click(function() {
var thisDescription = $('.service_description', $(this));
var t = $(this);
if(t.hasClass('open'))
{
t.removeClass('open');
t.find('.status').html("+");
}else {
t.addClass('open');
t.find('.status').html("-");
}
// Hide all other descriptions
$('.service_description').not(thisDescription).hide();
// Toggle (show or hide) this description
thisDescription.slideToggle(500);
});
the working example
I'd suggest simply toggling a class to achieve this.
You can add the icon as a background image of a pseudo element inserted into the .service_title element. Then you can simply toggle a class in order to change the icon. Update the background image URLs accordingly. See the updated example for the modified jQuery; it's still only 5 lines.
The relevant CSS:
.service_title:before {
content: '';
background: url('http://i.stack.imgur.com/GC7i2.png') 0 0 / 10px 10px no-repeat;
width: 10px;
height: 10px;
display: inline-block;
vertical-align: middle;
}
.closed .service_title:before {
background-image: url('http://i.stack.imgur.com/ma4L4.png');
}
Updated Example:
$('.service_wrapper').click(function() {
var thisDescription = $('.service_description', $(this));

You could just change it within your click binding...
Let's say your using images, just add a data-attribute you can query when you need to, like this...
HTML
<div class="service_wrapper">
<img data-state="plus" class="state" src="plus.png" alt="More"/>
<div class="service_title">Paint</div>
<div class="service_description">Fabulous paint!</div>
</div>
JS
$('.service_wrapper').click(function() {
var state = $(this).find('.state');
if(state.data('state') == 'plus')
state.attr({ 'src': 'minus.png', 'alt': 'Less' }).data('state', 'minus');
else
state.attr({ 'src': 'plus.png', 'alt': 'More' }).data('state', 'plus');
});
