I have a toDo list for the very first list, I can add elements. I can also create multiple toDo lists dynamically, but while adding here it is been added to the very first list instead of the respective list where I click. Please someone help me, I am very new to JavaScript.
$toDoList = $('#toDoList');
$newTodoList = $('#newTodoList');
$parent = $('#parent');
$ul = $('ul');
$totalList = $('.totalList');
$(".remove").click(function() {
confirm('Are you sure? do you want to delete the item') ? $(this).parent().remove() : $(this);
});
$("li").click(function() {
$(this).hasClass("addBorder") ? $(this).removeClass("addBorder") : $(this).addClass("addBorder");
});
$('body').on('click', '.add', function() {
var itemName = $('#itemName').val();
var listItem = $('<li>' + itemName + '<button type="button" class="buttonStyle">-</button></li>');
listItem.on("click", function() {
confirm('Are you sure? do you want to delete the item') ? $(this).remove() : $(this);
});
$totalList.append(listItem);
$('#itemName').val('');
});
index = 1;
i = 1;
function addNewList() {
var newList = $('<div class="listParent" id="newList"><button type="button" class="addNewList" onClick="addNewList()">+</button><h2>My ToDO List!!</h2><ul id="toDoList" class="totalList"><li>Java script<button type="button" class="remove buttonStyle">-</button></li><li>Angular<button type="button" class="remove buttonStyle">-</button></li><li>Jasmine<button type="button" class="remove buttonStyle">-</button></li></ul><div class="inputText"><input type="text" id="itemName" class="leftmargin10" name="ListItem"><button type="button" id="addButton" class="buttonPlacement buttonStyle add">+</button></input></div></div>');
$('#newList').clone().attr('id', 'newList' + index++)
.insertAfter($('[id^=newList]:last'));
}

The first thing I saw was that you are using multiple times the same id.
So I removed them all, since the "to do list" is to be cloned.
I simplified your code... I hope this will help.
// Remove (Delegate the clicks)
$(document).on("click",".remove",function(){
confirm('Are you sure? do you want to delete the item')? $(this).parent().remove():$(this);
});
// Li border (Delegate the clicks)
$(document).on("click","li",function(){
$(this).hasClass("addBorder")?$(this).removeClass("addBorder"):$(this).addClass("addBorder");
});
// Add a to do item to the list where the add button has been clicked.
$('body').on('click', '.add', function () {
// Find the relevant elements.
var thisParent = $(this).closest(".listParent");
var newTodoVal = thisParent.find(".newToDo");
var thisList = thisParent.find(".totalList");
// If there in a name inputed.
if(newTodoVal.val() !=""){
var listItem = "<li>"+newTodoVal.val()+"<button type='button' class='buttonStyle'>-</button>";
thisList.append(listItem);
newTodoVal.val('');
}
});
// Clone the last list to create a new one.
$(".addNewList").on("click",function(){
var lastList = $(".listParent").last();
lastList.clone().insertAfter(lastList);
});
.addBorder{
border:1px solid black;
max-width:10em;
}
.leftmargin10{
margin-left:10px;
}
.buttonStyle{
margin-left:0.5em;
}

I assume that you click the + to add an item to a list.
You have this line of code:
$totalList.append(listItem);
In theory that should append listItem to every list which has class='totalList', I think you want it added only to the list where the + button was clicked, so I would change that line to
$(this).closest('.totalList').append(listItem);

Here is the source code:
$(document).on('click', '.number-spinner button', function() {
var btn = $(this),
oldValue = btn.closest('.number-spinner').find('input').val().trim(),
newVal = 0;
newVal = (btn.attr('data-dir') === 'up') ? parseInt(oldValue) + 1 : (oldValue > 1) ? parseInt(oldValue) - 1 : 0;
btn.closest('.number-spinner').find('input').val(newVal);
});
let html = data.reduce((acc, {name,value,image,counter,totalMoney}) =>
acc + `
<div class='card col-md-3'>
<img class='card-img-top' src="${image}" alt='Card image cap'>
<div class='card-body'>
<h5 class='card-title'>${name}</h5>
<p class="card-text">${value}</p>
<input class="money-input money" value="${value}"/>
<div class="number-spinner">
<div class="input-group number-spinner">
<span class="input-group-btn">
<button type="button" class="btn btn-default btn-number btn-minus" data-type="minus" data-dir="dwn"><span>-</span></button>
</span>
<input min="1" class="adet input-number" value="${counter}" type="number">
<span class="input-group-btn">
<button type="button" class="btn btn-default btn-number btn-plus" data-type="plus" data-dir="up"><span>+</span></button>
<div class="total-price"></div>
</span>
</div>
</div>
<button class="submit">Add To Card</button>
</div>
</div>`
, ``);
$('#list').append(html);
const adet = $(".adet").val()
const money = $(".money").val()
const totalMoney = adet * money;
var endText = 'Price'
var space = ' '
$( ".submit" ).click(function() {
$(".total-price").text($(".adet").val() * totalMoney);
$('.total-price').append( space + endText);
});
The "problem" is that you have (possibly) multiple elements with the class .adet and .money. However, the .val() method of a jQuery collection only extracts the value of the first element it contains. See the jQuery docs:
Get the current value of the first element in the set of matched elements...

I am trying to implement a dynamic increment/decrement counter. Here is how it should work:
I have an 'ADD' button. When i click on this, the same should disappear and a minus button, number input, plus button should appear. Clicking on "+" should increment the counter on the "cart" and clicking on "-" should decrement.
Below is html mycode
<body>
<div id="page-wrap">
<h1>Cart Inc Dec</h1>
<a href="#" class="btn btn-info btn-lg mt-5 mr-5 mb-5">
<span class="glyphicon glyphicon-shopping-cart"><span id="itemCount"></span></span> Check Out
</a>
<br>
<a id="btnAddItem" class="btn btn-primary float-right mt-5 mb-5 mr-5">ADD</a>
<div class="addItem">
</div>
</div>
</body>
Jquery:
<script>
var addElement = 0;
$(document).ready(function(){
$("#btnAddItem").on("click", function (event) {
if(addElement==0){
$(".addItem").append(('<button type="button" class="counter decrease">-</button><input type="text" size="5" id="txtCounter" /><button type="button" class="counter increase">+</button>'));
}
addElement++;
});
var $input = $("#txtCounter");
// Initialise the value to 0
$input.val(0);
debugger;
// Increment/decrement count
$(".counter").click(function(){
console.log('here i am');
if ($(this).hasClass('increase'))
$input.val(parseInt($input.val())+1);
else if ($input.val()>=1)
$input.val(parseInt($input.val())-1);
});
});
</script>
Now the problem is after i add the dynamic +, text input counter, - controls, nothing happens when i click on + or minus. console.log inside $(".counter").click(function() is not giving anything.
Am i missing something??
You can do it like this: Adjust the $(".counter").click(function() {}); to $(document).on("click", ".counter", function(){}); as the element with the class counter isn't there when the page is initially loaded and therefore the click() event has to be delegated from a static parent element to the added counter element using on(). Move then the variable declaration var $input = $("#txtCounter"); inside this click function as the element with the id txtCounter isn't there when the page is initally loaded and move the initialization $("#txtCounter").val(0); after appending it.
var addElement = 0;
$(document).ready(function() {
$("#btnAddItem").on("click", function(event) {
if (addElement == 0) {
$(".addItem").append(('<button type="button" class="counter decrease">-</button><input type="text" size="5" id="txtCounter" /><button type="button" class="counter increase">+</button>'));
// Initialise the value to 0
$("#txtCounter").val(0);
}
addElement++;
});
// Increment/decrement count
$(document).on("click", ".counter", function() {
var $input = $("#txtCounter");
if ($(this).hasClass('increase')) {
$input.val(parseInt($input.val()) + 1);
} else if ($input.val() >= 1) {
$input.val(parseInt($input.val()) - 1);
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="page-wrap">
<h1>Cart Inc Dec</h1>
<a href="#" class="btn btn-info btn-lg mt-5 mr-5 mb-5">
<span class="glyphicon glyphicon-shopping-cart"><span id="itemCount"></span></span> Check Out
</a>
<br>
<a id="btnAddItem" class="btn btn-primary float-right mt-5 mb-5 mr-5">ADD</a>
<div class="addItem">
</div>
</div>
You can change the script and try something like below:
var addElement = 0;
var myCounter= function(action){
var val = document.getElementById("txtCounter").value;
val = parseInt(val);
if(action == 2){ //Increase
document.getElementById("txtCounter").value=val+1;
}else if(val > 1){
document.getElementById("txtCounter").value=val-1;
}
};
$(document).ready(function(){
$("#btnAddItem").on("click", function (event) {
if(addElement==0){
$(".addItem").append(('<button type="button" onclick="myCounter(1);" class="counter decrease">-</button><input type="text" size="5" id="txtCounter" value="0" /><button type="button" onclick="myCounter(2);" class="counter increase">+</button>'));
}
addElement++;
});
});
I have a couple of buttons
<button id="btn-ok[1]" class="btn-ok"></button>
<button id="btn-failed[1]" class="btn-failed"></button>
<button id="btn-ok[2]" class="btn-ok"></button>
<button id="btn-failed[2]" class="btn-failed"></button>
<button id="btn-ok[3]" class="btn-ok"></button>
<button id="btn-failed[3]" class="btn-failed"></button>
And I am running differnt jquery functions for btn-ok and for btn-failed.
I would like to use the index number of the id. How can I obtain it?
<script>
$(document).ready(function() {
$('#btn-ok').click(function() {
console.log('I would like to print the index of the pressed button here. (i.e. 1,2,3)');
});
});
</script>
Use html5's data attributes and separate the index and status into separate elements - I added some teext to each button so it could be easily seen and then the click grabs the data-attributes and console.logs the values.
$(document).ready(function() {
$('.btn').click(function() {
var index = $(this).data('index');
var status = $(this).data('status')
console.log(index + ' / ' + status);
}); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<button data-index="1" data-status ="ok" class="btn btn-ok">1 Ok</button>
<button data-index="1" data-status ="failed" class="btn btn-failed">1 Failed</button>
<button data-index="2" data-status ="ok" class="btn btn-ok">2 OK</button>
<button data-index="2" data-status ="failed" class="btn btn-failed">2 Failed</button>
<button data-index="3" data-status ="ok" class="btn btn-ok">3 OK</button>
<button data-index="3" data-status ="failed" class="btn btn-failed">3 Failed</button>
Create a collection of all those buttons to index against. Note that index() is zero based
var $buttons = $('.btn-ok, btn-failed').click(function(){
alert($buttons.index(this));
})
Or for more specifc target:
var $buttons = $('.btn-ok, btn-failed');
$('#btn-ok\\[1\\]').click(function(){
alert($buttons.index(this));
})
Or use data attributes instead of messing around with [] in ID
<button class="btn-ok" data-index="1"></button>
..
$('.btn-ok').click(function(){
alert($(this).data('index'));
})
HTML id's shouldn't use an index. Instead use a class to hold the selector and a data attribute to hold the other values you'll need like this:
The HTML:
<button class="btn-ok" data-index="1">Ok</button>
The JS:
$('.btn-ok').click(function() {
$(this).data('index');
});
The fiddle:
https://jsfiddle.net/kLvqe8dw/2/
did you mean to get id ?
$("button").click(function(){
alert($(this).attr('id'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="btn-ok[1]" class="btn-ok">ok[1]</button>
<button id="btn-failed[1]" class="btn-failed">failed[1]</button>
<button id="btn-ok[2]" class="btn-ok">ok[2]</button>
<button id="btn-failed[2]" class="btn-failed">failed[2]</button>
<button id="btn-ok[3]" class="btn-ok">ok[3]</button>
<button id="btn-failed[3]" class="btn-failed">failed[3]</button>
I have inserted button by onclick in a way that if you click on the button then it will append within <div id="article-tags"></div> just like the below image,
To create that, I have arranged the HTML code segment below:
<div id="article-tags">
</div>
<div>
<button type="button" data-id="1" data-name="tag" class="tag-item">tag</button>
<button type="button" data-id="2" data-name="tag2" class="tag-item"> tag2</button>
<button type="button" data-id="3" data-name="tag3" class="tag-item">tag3</button>
<button type="button" data-id="4" data-name="tag4" class="tag-item">tag4</button>
</div>
And the jQuery code segment is below,
$(".tag-item").click(function(){
var btnid = $(this).data("id");
var btnname = $(this).data("name");
$("#article-tags").append("<button type='button' class='tag-selected ntdelbutton'>"+ btnname +" <i class='fa fa-times-circle' aria-hidden='true'></i></button>");
$(this).css({"background-color": "#DFE2E5", "color": "#ababab"});
$(this).attr("disabled", true);
return false;
});
But right now, I would like to remove the button by onClick that is populated within
<div id="article-tags"></div>
I have tried to by using the following jQuery code segment below:
$(".tag-selected").click(function(){
$(this).remove();
});
or
$(".tag-selected").live("click", function() {
$(this).remove();
});
But neither is working. Please help me to solve this problem.
Try following code. Do you want to restore 'disabled': false attribute after removing specified element?
$(".tag-item").click(function() {
var btnid = $(this).data("id");
var btnname = $(this).data("name");
$("#article-tags").append("<button type='button' class='tag-selected ntdelbutton'>" + btnname + " <i class='fa fa-times-circle' aria-hidden='true'></i></button>");
$(this).css({
"background-color": "#DFE2E5",
"color": "#ababab"
});
$(this).attr("disabled", true);
$(".ntdelbutton").click(function() {
$(this).remove();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="article-tags">
</div>
<div>
<button type="button" data-id="1" data-name="tag" class="tag-item">tag</button>
<button type="button" data-id="2" data-name="tag2" class="tag-item"> tag2</button>
<button type="button" data-id="3" data-name="tag3" class="tag-item">tag3</button>
<button type="button" data-id="4" data-name="tag4" class="tag-item">tag4</button>
</div>
Here is an approach using plain javascript (rather than the jQuery library) and a dash of CSS:
var upperButtons = document.querySelectorAll('.upper button');
var lowerButtons = document.querySelectorAll('.lower button');
for (let i = 0; i < lowerButtons.length; i++) {
lowerButtons[i].addEventListener('click', function(){upperButtons[i].style.visibility = 'visible'; lowerButtons[i].setAttribute('disabled','disabled');}, false);
}
for (let i = 0; i < upperButtons.length; i++) {
upperButtons[i].addEventListener('click', function(){upperButtons[i].removeAttribute('style'); lowerButtons[i].removeAttribute('disabled');}, false);
}
.upper button {
visibility: hidden;
}
<div class="upper">
<button type="button">tag</button>
<button type="button">tag2</button>
<button type="button">tag3</button>
<button type="button">tag4</button>
</div>
<div class="lower">
<button type="button">tag</button>
<button type="button">tag2</button>
<button type="button">tag3</button>
<button type="button">tag4</button>
</div>
I have two div html elements with different id and here I am using spinner. Whenever values in the spinner input changes alert box will be displayed.

$(function(){
$('.spinner:first-of-type input').on('click', function() {
$('.spinner:first-of-type input').val(parseInt($('.spinner:first-of-type input').val(), 10) + 1);
var val = $('.spinner:first-of-type input').val();
changeValues(val);
});
$('.spinner:last-of-type input').on('click', function() {
$('.spinner input').val( parseInt($('.spinner input').val(), 10) - 1);
});
function changeValues(value){
alert($('#energy').attr('class').split(' '));
};
});
But in the alert box whenever I click the spinner up arrow only Tea is displayed.
what I expect is when the spinner is clicked from Tea div tea should be displayed and when from coffee , coffee should be displayed.Please help me out
I'm not sure I totally got what you are trying to do, but it seems to me that you want to increment and decrement number of beverage cups on up/down buttons click. For this you would better modify mark up a little (remove duplicated ids, add classes for convenience). And I may look like this then:
$(function() {
$('.spinner').on('click', '.servings', function(e) {
$(this).val(parseInt($(this).val() || 0, 10) + 1);
var val = $(this).val();
changeValues.call(e.delegateTarget, val);
})
.on('click', '.up', function(e) {
$(e.delegateTarget).find('.servings').val(function() {
return ++this.value;
});
})
.on('click', '.down', function(e) {
var $input = $(e.delegateTarget).find('.servings');
if (+$input.val() > 1) {
$input.val(function() {
return --this.value;
});
}
});
function changeValues(value) {
var type = $(this).find('.energy').data('type');
alert(type);
};
});
Demo: http://plnkr.co/edit/9vXC0RipxkzqhXrHJAKD?p=preview
try this:
$(function () {
$('.spinner').each(function () {
var $el = $(this),
$buttons = $el.find('button'),
$h4 = $el.find('h4'),
input = $el.find('input').get(0);
function showAlert() {
alert($h4.get(0).className);
}
$buttons.eq(0).on('click', function (event) {
event.preventDefault();
input.value = (parseInt(input.value, 10) || 0) + 1;
showAlert();
});
$buttons.eq(1).on('click', function (event) {
event.preventDefault();
input.value = (parseInt(input.value, 10) || 0) - 1;
});
});
});
