Array wont update when i JSON.stringify it

I have this code below that is able to transfer the array value to another array when i click on it. For Example, when i click on lime it will move into my Green Array The problem is after i JSON.stringify my Green Array it doesn't show the updated value.
So this is the before i add in a value my green array has 5 values.
And this is after I add in a value to my green array as you can see after I move the value in my array count increases but I don't know why when i stringify the array, it doesn't have the value I added in already I want to stringify it because I want to send the updated data to a server. Is there any reason why this is happening ?

It is working fine as expected. Look into the code base properly may be you are missing something.
var greenFruits = ["Watermelon", "Durian", "Avacado", "Lime", "Honeydew"];
console.log("Green Fruits Object : ", greenFruits);
console.log("Green Fruits String : ", JSON.stringify(greenFruits));
greenFruits.push("Guava");
console.log("Green Fruits Object : ", greenFruits);
console.log("Green Fruits String : ", JSON.stringify(greenFruits));

How to make divs names always be 1,2,3 jQuery

My issue is that when i append 2 divs white jQuery, there names are:
This is div 1
This is div 2
But when i remove the first div (This is div 1)
and append another div
it adds one more div whit name (This is div 2):
This is div 2
This is div 2
The reason is because the name of the div counts the total amout of divs... Is there any other way to number all divs so they will always be like this:
This is div 1
This is div 2
This is div 3
Even if i the divs are:
This is div 1
This is div 6
This is div 12
I want them always to be 1,2,3
jQuery code:
$('#add_item').click(function() {
//div count
var countDivs = $("div").length;
//append content
var removeBtn = ('<a class="removeBtn">x</a>')
var h2 = ('<h2>This is div '+countDivs+'</h2>')
var appendContent = ('<div>'+h2+removeBtn+'</div>')
$('#accordion').append(appendContent);
});
//remove button
$(document).on('click', '.removeBtn', function() {
$(this).parent('div').andSelf().remove();
return false;
});
JSFIDDLE

I think you'll have to edit contents of the divs each time a div is removed.
Let's say you have an element and you want to add divs to it.
You will add like you are right now and when you remove you edit all other divs.
The code would be something like this
$('#add_item').click(function() {
var countDivs = $("div").length;
var removeBtn = ('<a class="removeBtn">x</a>')
var h2 = ('<h2>This is div '+countDivs+'</h2>')
var appendContent = ('<div class="appDiv">'+h2+removeBtn+'</div>')
$('#accordion').append(appendContent);
});
$(document).on('click', '.removeBtn', function() {
$(this).parent('div').andSelf().remove();
$('.appDiv').each(function(index,el){
$(el).find('h2').text('This is div '+(index+1));
});
return false;
});
here is the Fiddle
Hope this helps :)

Write a function to renaming the divs and call it after append/remove.
function reArrange() {
$("#accordion > div").each(function(i) {
$(this).find("h2").text("This is div" + (i + 1))
});
}
Fiddle

When an item is removed, change the title of all the elements after it.
$('#add_item').click(function() {
var countDivs = $("#accordion div").length + 1;
var removeBtn = ('<a class="removeBtn">x</a>')
var h2 = ('<h2>This is div <span>' + countDivs + '</span></h2>')
var appendContent = ('<div>' + h2 + removeBtn + '</div>')
$('#accordion').append(appendContent);
});
$(document).on('click', '.removeBtn', function() {
var $div = $(this).parent();
$div.nextAll('div').find('span').html(function(i, html) {
return --html
});
$div.remove();
return false;
});
div {
position: relative;
}
#accordion {
margin-left: 60px;
padding: 10px;
background: #ddd;
}
#add_item {
position: absolute;
top: 20px;
left: 20px;
font-size: 20px;
padding: 5px 10px;
background: black;
color: white;
cursor: pointer;
}
.removeBtn {
font-size: 20px;
padding: 2px 10px 5px;
background: black;
color: white;
cursor: pointer;
position: absolute;
top: 0px;
font-family: verdana;
border-radius: 100%;
left: 200px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="accordion">
</div>
<a id="add_item">+</a>

you should use a global variable like "count":
var count=1;
$('#add_item').click(function() {
//div count
//var countDivs = $("div").length;
var countDivs =count;
//append content
var removeBtn = ('<a class="removeBtn">x</a>')
var h2 = ('<h2>This is div '+countDivs+'</h2>')
var appendContent = ('<div>'+h2+removeBtn+'</div>')
$('#accordion').append(appendContent);
count++;
});
//remove button
$(document).on('click', '.removeBtn', function() {
$(this).parent('div').andSelf().remove();
return false;
});

The easiest update would be to trigger a recount (or other named-event) and, upon addition or removal of an element – by clicking either the #add_item or .removeBtn – call that function using the on() method to listen for that event.
In the below code we bind the event-listener to the #accordion element, as the closest ancestor present in the DOM on page load:
$('#add_item').click(function() {
var removeBtn = ('<a class="removeBtn">x</a>');
var h2 = ('<h2></h2>');
var appendContent = ('<div>'+h2+removeBtn+'</div>');
$('#accordion').append(appendContent).trigger('recount');
});
$(document).on('click', '.removeBtn', function() {
$(this).parent('div').andSelf().remove();
// triggering the 'recount' event from the
// #accordion:
$('#accordion').trigger('recount');
return false;
});
// listening for the 'recount' event:
$('#accordion').on('recount', function(){
// looking within the #accordion for
// the <h2> elements (which contain the
// text to update), and using the text()
// method's anonymous function along with
// its i argument (the index of the current
// <h2> in the collection):
$(this).find('h2').text(function(i){
// returning the text string concatenated
// with the index plus 1 (to get a 1-based
// count, rather than JavaScript's 0-based):
return 'This is div ' + (i + 1);
});
});
$('#add_item').click(function() {
var removeBtn = ('<a class="removeBtn">x</a>');
var h2 = ('<h2></h2>');
var appendContent = ('<div>' + h2 + removeBtn + '</div>');
$('#accordion').append(appendContent).trigger('recount');
});
$(document).on('click', '.removeBtn', function() {
$(this).parent('div').andSelf().remove();
$('#accordion').trigger('recount');
return false;
});
$('#accordion').on('recount', function() {
$(this).find('h2').text(function(i) {
return 'This is div ' + (i + 1);
});
});

How can I search in the js array?

I'm trying to suggest the name of people when user inputs # in the textarea. Here is what I have done so far:
var Names = $('td').map(function() { return $(this).text(); }).get();
function SuggestPeople() {
var $textarea = $('.TxtArea');
var textarea = $textarea[0];
var sel = $textarea.getSelection();
var val = textarea.value;
var pos = sel.start;
if(val.substr(pos-1,1) == '#'){
for (var i = 0; i < Names.length; i++) {
Names[i] = "<span>" + Names[i] + "</span>";
}
$('.SuggestPeople').html(Names);
} else {
$('.SuggestPeople').html('');
}
}
$('.TxtArea').on('keydown click', function(e) {
// e.preventDefault();
SuggestPeople();
});
table{
display:none;
}
div{
background-color:#eee;
min-height: 20px;
width: 200px;
padding-top:5px;
margin-bottom: 3px;
}
div > span{
border: 1px solid gray;
margin: 0 3px;
}
textarea{
width: 195px;
height: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://rangyinputs.googlecode.com/svn/trunk/rangyinputs_jquery.min.js"></script>
<table>
<tr>
<td>Jack</td>
<td>Peter</td>
<td>Barmar</td>
</tr>
</table>
<div class="SuggestPeople"></div>
<textarea class="TxtArea"></textarea>
In the code above, it suggests all names (which are exist in the array) to user. But actually I need to improve it and just suggest those names which are near to what user writes after #. How can I do that? I want exactly something like stackoverflow.

Here's a solution that should work for you:
// polyfills for older browsers
if (!String.prototype.startsWith) {
String.prototype.startsWith = function(searchString, position){
position = position || 0;
return this.substr(position, searchString.length) === searchString;
};
}
// code
var Names = $('td').map(function () {
return $(this).text();
}).get();
function SuggestPeople(e) {
var val = e.target.value,
suggest = document.getElementById('SuggestPeople');
if (val.substr(- 2).startsWith('#')) {
suggest.innerHTML = '<span>' + Names.map(function (v) {
var end = val.substr(- 1).toLowerCase();
if (v.startsWith(end) || v.startsWith(end.toUpperCase())) {
return v;
}
}).filter(function (v) {
return v
}).join('</span><span>') + '</span>'
} else {
suggest.innerHTML = '';
}
}
$('.TxtArea').on('keyup', function (e) {
// e.preventDefault();
SuggestPeople(e);
});
table{
display:none;
}
div{
background-color:#eee;
min-height: 20px;
width: 200px;
padding-top:5px;
margin-bottom: 3px;
}
div > span{
border: 1px solid gray;
margin: 0 3px;
}
textarea{
width: 195px;
height: 100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://rangyinputs.googlecode.com/svn/trunk/rangyinputs_jquery.min.js"></script>
<table>
<tr>
<td>Jack</td>
<td>Peter</td>
<td>Barmar</td>
</tr>
</table>
<div id="SuggestPeople"></div>
<textarea class="TxtArea"></textarea>
Please note that String.prototype.startsWith() doesn't work in IE and older browsers, but you can find a polyfill here: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/String/startsWith

how to work with arrays and objects in javascript

I've got an array of cars and i'm looping through each car. I take input from the user using window.prompt() method. I take that value and filter it through my array of cars. I just want to know how I can restrict the car name the user selects to only those in the array
Fiddle : https://jsfiddle.net/qomu1fny/
var CarsWorld = {
cars : ['Honda','toyota','mercedes','jaguar'],
init: function(){
var getData = prompt('Which Car You Wanna Drive','');
for(var i = 0 ; i < this.cars.length ; i++){
$('.wrap').append(' ' + this.cars[i] + ' <br/> ');
}
},
};
CarsWorld.init();

var getData = prompt('Which Car You Wanna Drive','');
var foundCar = "";
for(var i = 0 ; i < this.cars.length ; i++){
$('.wrap').append(' ' + this.cars[i] + ' <br/> ');
//check if this car in the array is the picked car
if(this.cars[i] == getData){
foundCar = getData;
}
}
$('.wrap').append('you picked ' + foundCar);
Note that if the car isn't on the list then it won't output anything. Fiddle here: http://jsfiddle.net/e5qh3pvw/

I've tried to rephrase your question to something more understandable (currently under peer review). I understand you want to have a prompt that will restrict the choices of the user to the car models in your array.
Unfortunately, window.prompt() cannot achieve this, neither is there any synchronous (blocking) way to achieve it. You will need to use a modal dialog, and insert a regular html select element with your choices, or use a group of radio buttons.
I have created a fiddle that started getting bloated as I progressed. I used a few advanced techniques, just to engage your curiousity, since I suspect you are new to javascript.
Javascript:
var CarsWorld = {
cars : ['Honda','toyota','mercedes','jaguar'],
init: function(){
var getData = 'none';
for(var i = 0 ; i < this.cars.length ; i++){
$('.wrap').append(' ' + this.cars[i] + ' <br/> ');
}
var prompter = new CarsWorld.PromptSelect('Which Car You Wanna Drive', function(selected){
getData = selected;
alert('You chose '+ getData +'! ');
//other logic you want to apply on getData
});
prompter.show();
}
};
CarsWorld.PromptSelect = function(message, callback) {
self = this;
this.init = function(){
self.dropdown = '<select id="selectedCar">';
$.each(CarsWorld.cars, function(index, car){
self.dropdown += '<option>' + car + '</option>';
});
self.dropdown += '</select>';
self.markup = [
'<div class="prompt">',
'<div class="title">CarsWorld Prompt</div>',
'<div class="body">',
'<label for="selectedCar">'+ message +':</label>' + this.dropdown + '</div>',
'<div class="footer">',
'<button class="btn-ok">Ok</button>',
'<button class="btn-cancel">Cancel</button>',
'</div>',
'</div>'
].join('');
};
this.show = function(){
$('.overlay').show();
$('body').css('overflow', 'hidden');
self.init();
$('body').append(self.markup);
$('.prompt .btn-ok').on('click', function(){
self.hide();
callback($('#selectedCar').val());
self.destroy();
});
$('.prompt .btn-cancel').on('click', function(){
self.destroy();
});
return self;
};
this.hide = function(){
$('.prompt').hide();
$('.overlay').hide();
$('body').css('overflow', 'auto');
return self;
};
this.destroy = function(){
self.hide();
return self;
};
};
CarsWorld.init();

Accordian Element Height Issue

I have implemented 2 types of Accordians for my application- 1 Column and 2 Column
Im having a problem with the Static Height for the 1 Column Accordian. And I've been trying to modify the JavaScript all day but cant seem to get it to work.
The Heights should be dynamic in Height depending upon the amount data, however as you can see the Height is fixed, and some of the data is getting cut off:
http://www.davincispainting.com/whydavincis.aspx
The other 2 Column Accordian has almost the same JavaScript as the 1 Column Accordian, however the Height is dynanmic depending on how much data there is:
http://www.davincispainting.com/glossary.aspx
I would provide a Fiddle however the Data is now dynamic:
Here is the JavaScript for the problem Accordian:
<script type="text/javascript">
$.fn.accordion = function () {
return this.each(function () {
$container = $('#mid-featureleft-client');
$container.find("dt").each(function () {
var $header = $(this);
var $selected = $header.next();
$header.click(function () {
$('.active').removeClass('active');
$(this).addClass('active');
if ($selected.is(":visible")) {
$selected.animate({
height: 0
}, {
duration: 300,
complete: function () {
$(this).hide();
}
});
} else {
$unselected = $container.find("dd:visible");
$selected.show();
var newHeight = heights[$selected.attr("id")];
var oldHeight = heights[$unselected.attr("id")];
$('<div>').animate({
height: 1
}, {
duration: 300,
step: function (now) {
var stepSelectedHeight = Math.round(newHeight * now);
$selected.height(stepSelectedHeight);
$unselected.height(oldHeight + Math.round((newHeight - oldHeight) * now) - Math.round(newHeight * now));
},
complete: function () {
$unselected.hide().css({
height: 0
});
}
});
}
return false;
});
});
// Iterate over panels, save heights, hide all.
var heights = new Object();
$container.find("dd").each(function () {
$this = $(this);
$this.css("overflow", "hidden");
heights[$this.attr("id")] = $this.height();
$this.hide().css({

});
});
});
};
$(document).ready(function () {

$.each(datas, function () {

str_one += "<dd class=\"glossanswer\" style=\"-webkit-margin-start:0px\"><div class=\"answerbox\">" + this['Answer'] + "</div></dd>";
});
str_one += "</dl>";
$("#glossary_first").html(str_one);

The problem is with the way you're storing the heights, a bit after this comment:
// Iterate over panels, save heights, hide all.
Specifically, this line:
heights[$this.attr("id")] = $this.height();
Your dd elements don't have an id, so on each iteration of the loop, heights[''] is being set to the height of the current dd.
You should be able to fix it by changing this:
$.each(datas, function () {
str_one += "<dt class=\"glossquestion\">" + this['Question'] + "</dt>";
str_one += "<dd class=\"glossanswer\" style=\"-webkit-margin-start:0px\"><div class=\"answerbox\">" + this['Answer'] + "</div></dd>";
});
to this:
var i = 0;
$.each(datas, function () {
str_one += "<dt class=\"glossquestion\">" + this['Question'] + "</dt>";
str_one += "<dd id=\"rand_" + i + "\" class=\"glossanswer\" style=\"-webkit-margin-start:0px\"><div class=\"answerbox\">" + this['Answer'] + "</div></dd>";
i++;
});
I'm just going to point out that my fix doesn't seem very jQuery-esque, and your entire code seems complicated for what it's doing.
If you changed your JSON to something like this:
[{"Question1":"..","Answer1":".."},{"Question2":"..","Answer2":".."}, .. ]
You could do this:
$.each(datas, function (i, v) {
str_one += "<dt class=\"glossquestion\">" + this['Question'] + "</dt>";
str_one += "<dd id=\"Dd" + i + "\" class=\"glossanswer\" style=\"-webkit-margin-start:0px\"><div class=\"answerbox\">" + this['Answer'] + "</div></dd>";
});
which is cleaner code than incrementing our own variable i inside $.each.
