Creating dynamic cards using jQuery - javascript

I'm doing an e-trade site with jQuery; however, when I increase then submit one of the products, they all get the properties of the first product. I defined the products as a json to a variable.
How can I create dynamic cards with jquery?
Here is how it looks:
İmage
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...

Dynamically add increment/decrement counter

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 can´t remove the last item of array

I can remove any item of array unless the last one. I also use angularjs to show information in the view. I don´t know what is happening with the last item of this array. Please, anyone can help me?
Here is HTML:
<div class="row">
<div class="col-md-12">
<h4><strong>Documento {{index + 1}} de {{documentos.length}}:</strong> {{documentos[index].nome}}</h4>
<iframe style="background: #ccc;" ng-show="exibirPreview" frameborder="0" ng-src="{{versaoLink}}" width="100%" height="300px"></iframe>
<div class="alert alert-warning" ng-hide="exibirPreview">
#Html.Raw(Resources.Dialog.SignDocuments.TypeDocumentCanNotPreDisplayed)
</div>
<hr />
<div class="pull-right btn-row" ng-show="documentos.length > 1">
<button class="btn btn-default" type="button" ng-click="RemoveDoc(index)"><i class="fa fa-fw fa-times"></i> #Resources.Common.RemoveDocList</button>
</div>
</div>
</div>
Here is js/angularjs
$scope.documentos = [
{nome:"document1", chave: "8F65579E3737706F", extensao:".pdf"},
{nome:"document2", chave: "8F65579E3730007F", extensao:".pdf"},
{nome:"document3", chave: "8545579E3737706F", extensao:".pdf"},
{nome:"document4", chave: "8555579E3730007F", extensao:".pdf"}
]
$scope.ViewLink = function () {
var versao = $scope.documentos[$scope.index];
$scope.exibirPreview = versao.extensao == ".pdf" || versao.extensao == ".txt";
if (!$scope.exibirPreview) {
$scope.versaoLink = '';
} else {
$scope.versaoLink = '/Documento/VersaoView?chave=' + versao.chave;
}
};
$scope.ViewLink();
$scope.RemoveDoc = function (index) {
$scope.documentos.splice(index, 1);
$scope.ViewLink();
};
Or Plunker
In your HTML you are preventing the deletion of the last element:
<div class="pull-right btn-row" ng-show="documentos.length > 1">
<!-- -->
</div>
documentos.length > 1 means "hide when it reaches one item in the array".
It should be documentos.length == 0.
It's either this or your index value starts from 1 and not from 0.
The simplest solution would be to change your remove function to take in the document instead of the index. Try this:
$scope.RemoveDoc = function(document) {
var index = $scope.documents.indexOf(document);
$scope.documents.splice(index, 1);
}
in view:
<button class="btn" type="button" ng-click="RemoveDoc(document)">Delete</button>

append element to dynamically generated div using same classnames - Jquery

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'));
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="parent" id="parent">
<div class="listParent" id="newList">
<button type="button" class="addNewList" onclick="addNewList()">+</button>
<h2>My ToDO List!!</h2>

<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>
<!-- New list -->
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;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="parent">
<button type="button" class="addNewList">+</button>
<div class="listParent">
<h2>My ToDO List!!</h2>
<ul 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" class="leftmargin10 newToDo" name="ListItem">
<button type="button" class="buttonPlacement buttonStyle add">+</button>
</div>
</div>
<!-- New list -->
</div>
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);

How to strip all elements but some?

I am generating <ul> and sub <ul>, what I would like to do is to place the html structure of the list only with its values in it. With the following code I get into the text area all the <ul> content not simply the:
HTML
<div id="mindMap">
<ul class="list-unstyled margin-bottom-20">
<li><button class="btn btn-default ul-appending margin-bottom-20">+ voce</button></li>
</ul>
</div>
<div id="mindMapData">
<textarea name="usp-custom-11" id="usp-custom-11" data-required="false" placeholder="Example Input 11" data-richtext="false" class="usp-input usp-textarea usp-form-365" rows="0" cols="30" style="margin: 0px; width: 871px; height: 291px;"></textarea>
</div>
jQuery
$('body').on('click', 'button.ul-appending', function() {
$(this).parent().append(
$('<ul class="main_ul list-unstyled margin-bottom-20">').addClass('newul').append(
$('<li class="margin-bottom-20"><div class="input-group margin-bottom-20"><input placeholder="Aggiungi una voce..." class="form-control" type="text"><div class="input-group-btn"><button type="button" class="btn btn-default list">+ sotto voce</button><button type="button" class="btn btn-default removeThis">elimina</button></div></div></li>')
)
);
});
$('body').on('click', 'button.list', function() {
var newLi = '<ul class="sub_ul list-unstyled margin-bottom-20"><li class="listSub margin-bottom-20"><div class="input-group margin-bottom-20"><input placeholder="Aggiungi una sotto voce..." class="form-control" type="text"><div class="input-group-btn"><button type="button" class="btn btn-default list">+ sotto voce</button><button type="button" class="btn btn-default removeThis">elimina</button></div></div></li></ul>';
var listEl = $(this).parent().parent().parent();
$(listEl).append(newLi);
});
Then I check for the the html changes and insert the html into the textarea like this:
$("#mindMap").on("DOMSubtreeModified",function(){
$("#mindMapData textarea").val($("#mindMap").html());
});
In the text area i get all the html tho:
<ul class="main_ul list-unstyled margin-bottom-20 newul">
<li class="margin-bottom-20">
<div class="input-group margin-bottom-20">
<input placeholder="Aggiungi una voce..." class="form-control" type="text">
<div class="input-group-btn">
<button type="button" class="btn btn-default list">+ sotto voce</button>
<button type="button" class="btn btn-default removeThis">elimina</button>
</div>
</div>
<ul class="sub_ul list-unstyled margin-bottom-20">
<li class="listSub margin-bottom-20">
<div class="input-group margin-bottom-20">
<input placeholder="Aggiungi una sotto voce..." class="form-control" type="text">
<div class="input-group-btn">
<button type="button" class="btn btn-default list">+ sotto voce</button>
<button type="button" class="btn btn-default removeThis">elimina</button>
</div>
</div>
</li>
</ul>
Here it is a working jsFiddle, see the content in the textarea is wrong, I am trying to get:
<ul>
<li>Added node
<ul>
<li>Added sub node</li>
</ul>
</li>
</ul>
You can traverse the DOM with this code:
function ul(indent) {
indent = indent || 4;
var node = $(this);
return node.removeAttr('class').children().map(function() {
var self = $(this);
var value = self.find('> .input-group input').val();
var sub_ul = self.find('> ul');
var ul_spaces = new Array(indent+4).join(' ');
var li_spaces = new Array(indent).join(' ');
if (sub_ul.length && ul) {
return li_spaces + '<li>' + value + '\n' + ul_spaces +
'<ul>\n' + ul.call(sub_ul, indent+8) + '\n' + ul_spaces + '<ul>\n' +
li_spaces + '</li>';
} else {
return li_spaces + '<li>' + value + '</li>';
}
}).get().join('\n');
}
function updateTree() {
$("#mindMapData textarea").val('<ul>\n' + $("#mindMap").clone().find('.main_ul').map(ul).get().join('\n') + '\n</ul>');
}
one side note you should call that updateTree function on keyup for each input because DOMSubtreeModified is not fired when input change it's value, see update fiddle http://jsfiddle.net/44yb96Lb/72/
I think parsing the DOM tree recursively and filtering out unwanted tags is much more easier to understand. Have a look:
/**
* #param {array<string>} allowedTags A list of tags that are allowed in the output
* #returns {function} A function that takes a jQuery elements and returns a copy with only the allowed elements
*/
function filterElementsFactory(allowedTags) {
allowedTags = allowedTags.map(function (tag) { return tag.toUpperCase(); });
/**
* #param {object} element jQuery element
* #returns {documentFragment}
*/
return function filterElements(element) {
element = element.clone();
var elementList = element.contents();
var finalElem = document.createDocumentFragment();
for (element of elementList) {
if (element.nodeType === Node.TEXT_NODE) {
finalElem.appendChild(element);
} else if (element.nodeType === Node.ELEMENT_NODE) {
if (allowedTags.indexOf(element.tagName) !== -1) {
var elemFrame = document.createElement(element.tagName);
elemFrame.appendChild(filterElements($(element)))
finalElem.appendChild(elemFrame);
} else {
finalElem.appendChild(filterElements($(element)));
}
}
};
return finalElem;
}
}
You can use this like this:
var allowedTags = ['ul', 'li'];
var filterElements = filterElementsFactory(allowedTags);
$("#mindMap").on("DOMSubtreeModified",function(){
var placeholderDiv = $('<div/>').append(filterElements($("#mindMap")));
$("#mindMapData textarea").val(placeholderDiv.html());
});

How to get the value of a particular input field using id in the html templates

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.

<div id="accordion2" class="panel-group">
<div id="Tea">
<div class="spinner Tea input-group ">
<input type="text" id = "servings" class="form-control input- sm" value="Tea"/>

</div>
JQuery code
$(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;
});
});
});
