Edit dynamically created li elements in jquery

I want the user to be able to edit dynamically created list items that are input into a ul by the user.
I have no problem changing other items but the fact that the li items don't exist until input by the user is stumping me. I don't have any id's or classes to select to add a dblclick event to and selecting the child elements of all ul doesn't seem to work.
In short I just want to either:
click an icon on each list item that will allow me to edit the text
or
just double click the text which will allow me to edit it. (dblclick because the items are already draggable.)
I've tried a number of things but I'm not sure where to start now.
Thanks!

One simple way to edit text is to replace the text with an input element with it's value set to the text as follows:
//Edit added li elements
$(document).on('dblclick', 'ul.toBeSaved.edit li', function() {
let inEdit = $('<input/>');
let toEdit = $(this);
toEdit.html( inEdit.val( toEdit.text() ) );
inEdit.focus().select();
});
$(document).on('focusout keypress', 'ul.toBeSaved.edit li input', function(e) {
if( e.which === 13 || e.type === 'focusout') {
let val = $(this).val();
$(this).closest('li').text( val );
}
});
DEMO
$(function() {
$("#newItem").focus();
//Adding a new items when click or enter pressed//
function addNewItem() {
let newInput = $("#newItem").val();
$("#stillToDo").append("<li>" + newInput + "</li>");
$("#newItem").val("");
$("#lastUpdated").text("Last updated " + Date());
};
$("#newItemBtn").click(addNewItem);
$("#newItem").keypress(function(e) {
if (event.which == 13) {
addNewItem();
}

Fix HTML header and button tag not updating text

I am trying to write some code that updates a header tag and a button tag. However, when I use the method .text(); it does not work. So I looked up the proper way to do it via other stack overflow questions, and I see basically the same thing. Everyone is telling me to use .text() or .html(). So I am really confused on why it is not working. I am not sure if it has anything to do with values already in the tag.
HTML:
<div class="contents">
<div class="card text-center myCard">
<div class="card-header"></div>
<div class="card-body">
<h5 class="card-title"></h5>
<p class="card-text"></p>
<button type="button" class="btn btn-primary ttBtn"></button>
</div>
<div class="card-footer text-muted"></div>
</div>
</div>
jQuery:
$(".eBtn").on(
"click",
function(event) {
event.preventDefault();
var href = $(this).attr('href');
console.log(href);
$.get(href, function(ary2, status) {
$("#displayAppName").val(ary2.appname);
$("#appcode").val(ary2.appcode);
$("#editStatus").val(ary2.status);
if (ary2.mapstatus == "" || ary2.mapstatus == null) {
mapBool = true;
$("#mapStatus").val("");
$("#createBtn").val('Create');
$('#modalCreateBtn').attr(
'href',
'/create?currentAppcode='
+ ary2.appcode
+ "&currentAcro="
+ ary2.acronym
+ "&currentAppname="
+ ary2.appname);
console.log("Card Create: " + $(".card-title").val());
} else {
$("#mapStatus").val("Mapped");
$("#createBtn").val('Edit');
$('#modalCreateBtn').attr(
'href',
'/edit?currentAppcode='
+ ary2.appcode
+ "&currentAcro="
+ ary2.acronym);
mapBool = true;
console.log("Card Edit: " + $(".card-title").val());
}
});
console.log("Main Boolean : " + this.mapBool)
console.log("Main Boolean : " + mapBool)
if(mapBool){
$(".card-title").text("Application Mapped!");
$(".card-text").text("Continue to view application");
$(".ttBtn").text("New Mapping after");
}
$("#exampleModal").modal();
});
jQuery Change HTML:
$(".card-title").text("Application Mapped!");

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>

Load More Button JS - Load new content on page

I'm trying to develop a Load-More button using Javascript calling an API done with PHP.
So far, so good. I can load the new objects in a range i += i + 4 (I load three new comments everytime I press the button).
This is my load-more button:
$(document).ready(function () {
$(".load-more").on('click', function () {
var tab = $(this).data('tab');
var next_page = $(this).data('next-page');
console.log(next_page);
console.log(tab);
$.get($(this).data('url') + '?tab=' + tab + '&page=' + next_page, function (data) {
addNewQuestions($.parseJSON(data));
});
});
});
And for every object loaded I want to print each of these html blocks.
<div class="question-summary narrow">
<div class="col-md-12">
<div class="votes">
<div class="mini-counts"><span title="7 votes">
{if $question['votes_count']}
{$question['votes_count']}
{else}
0
{/if}
</span></div>
<div>votes</div>
</div>
<div {if $question['solved_date']}
class="status answered-accepted"
{else}
class="status answer-selected"
{/if}
title="one of the answers was accepted as the correct answer">
<div class="mini-counts"><span title="1 answer">{$question['answers_count']}</span></div>
<div>answer</div>
</div>
<div class="views">
<div class="mini-counts"><span title="140 views">{$question['views_counter']}</span></div>
<div>views</div>
</div>
<div class="summary">
<h3>
<a href="{questionUrl($question['publicationid'])}" class="question-title" style="font-size: 15px; line-height: 1.4; margin-bottom: .5em;">
{$question['title']}
</a>
</h3>
</div>
<div class = "statistics col-sm-12 text-right" style="padding-top: 8px">
<span>
<i class = "glyphicon glyphicon-time"></i>
<span class="question-updated-at">{$question['creation_date']}</span>
</span>
<span>
<i class = "glyphicon glyphicon-comment"></i>
<span class="question-answers">{$question['answers_count']}</span>
</span>
</div>
</div>
</div>
The problem is that I have several conditions, as {if$question['votes_count']} and I'm struggling because I don't know how get those variables when rendering the html.
Then I found something but I can't figure out how to adapt to my case
On that addNewQuestions I think that a good approach would be:
function addNewQuestions(objects) {
$.each(objects, function (i, object) {
console.log(object);
var lastItem = $('div.active[role="tabpanel"] .question-line:last');
var newLine = lastItem.clone(true);
var newObject = newLine.find('.question-col:eq(' + i + ')');
newObject.find('.question-info-container').attr('data-id', object.publicationid);
newObject.find('.vote-count').html(object.votes);
updateTitleAndLink(newObject.find('.question-title'), object);
lastItem.after(newLine);
});
}
function updateTitleAndLink(questionTitle, object) {
questionTitle.attr('href', questionTitle.data('base-question-url') + object.publicationid);
questionTitle.html(object.title);
}
But nothing happens and I can't figure out why.
Any idea or suggestion?
Kind regards

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.
HTML code
<div id="accordion2" class="panel-group" style="display: block;">
<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 class="input-group-btn-vertical">
<button class="btn Tea btn-default">
<i class="fa fa-caret-up"></i>
</button>
<button class="btn Tea btn-default">
<i class="fa fa-caret-down"></i>
</button>
</div>
<h4 id="energy" class="Tea"> Tea </h4>
</div>
<div id="Coffee">
<div class="spinner Coffee input-group ">
<input type="text" id = "servings" class="form-control input-sm" value="Coffee"/>
<div class="input-group-btn-vertical">
<button class="btn Coffee btn-default">
<i class="fa fa-caret-up"></i>
</button>
<button class="btn Coffee btn-default">
<i class="fa fa-caret-down"></i>
</button>
</div>
<h4 id="energy" class="Coffee">Coffee</h4>
</div>
</div>
</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;
});
});
});
