What does the #feedback selector reference in the JQueryUI demos - javascript

I'm looking specifically at the "Selectable" demos. Here is the example code for reference:
<style>
#feedback { font-size: 1.4em; }
#selectable .ui-selecting { background: #FECA40; }
#selectable .ui-selected { background: #F39814; color: white; }
#selectable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
#selectable li { margin: 3px; padding: 0.4em; font-size: 1.4em; height: 18px; }
</style>
<script>
$(function() {
$( "#selectable" ).selectable();
});
</script>
</head>
<body>
<ol id="selectable">
<li class="ui-widget-content">Item 1</li>
<li class="ui-widget-content">Item 2</li>
<li class="ui-widget-content">Item 3</li>
<li class="ui-widget-content">Item 4</li>
<li class="ui-widget-content">Item 5</li>
<li class="ui-widget-content">Item 6</li>
<li class="ui-widget-content">Item 7</li>
</ol>
</body>
</html>
None of the HTML contains an id of "feedback" and I've tried commenting the #feedback styling in and out, but I can't see a difference.
Thanks


I think is copy-paste of the example css code of the jQuery UI selectable. It is needed only for the third example Serialize look at the <p id="feedback">.
Demo code:

</style>
<script>
$(function() {
$( "#selectable" ).selectable({
stop: function() {
var result = $( "#select-result" ).empty();
$( ".ui-selected", this ).each(function() {
var index = $( "#selectable li" ).index( this );
result.append( " #" + ( index + 1 ) );
});
}
});
});
</script>
</head>
<body>
<p id="feedback">
<span>You've selected:</span> <span id="select-result">none</span>.
</p>
<ol id="selectable">
<li class="ui-widget-content">Item 1</li>
<li class="ui-widget-content">Item 2</li>
<li class="ui-widget-content">Item 3</li>
<li class="ui-widget-content">Item 4</li>
<li class="ui-widget-content">Item 5</li>
<li class="ui-widget-content">Item 6</li>
</ol>
</body>
</html>


It's only used in the third demo...
In the serialize demo, if you check devtools, you'll see:
<p id="feedback">
<span>You've selected:</span> <span id="select-result">none</span>.

Get original parent ID if JQuery sortable element is moved from one parent to another

I am using the JQuery UI sortable plugin, using the "connect with" functionality to allow LI elements to be moved between two different parent lists.
I am trying to produce an alert showing the ID of the original list from which the LI element was contained when a list item is moved from either #sortable1 to #sortable2 or visa versa.
The Jquery I am trying to use this as follows:
$( function() {
$( "#sortable1, #sortable2" ).sortable({
connectWith: ".connectedSortable",
receive: function(e, ui) {
alert(ui.originalPosition.id);
}
}).disableSelection();
});
Currently this produced a undefined output, rather than #sortable1 to #sortable2.
I have included below a sample script recreating the issue I am having.

The ui object (Sortable) has a sender jQuery object that has as the originating element.
Set your alert to this: ui.sender[0].id and you'll have it.

Javascript Show/Hide text

I'm trying to have a list in which when a user clicks, an image shows up along with a text under it. Let's say for List 1, I want it to say "Price: $1" when the link is clicked. And then for List 2, "Price: $2" under the image when the link is clicked. The same functions as the image show/hide ideally. Then when clicked away, hides the elements. I'm fairly new to JS but here's what I've gathered so far:
$(function () {
$(".imgPreview").hide();
$(".unstyled li a").click(function () {
$(".imgPreview").show().find("img").attr("src", $(this).attr("href"));
return false;
});
$("body").click(function () {
$(".imgPreview").hide();
});
});
* {font-family: 'Segoe UI'; margin: 0; padding: 0; list-style: none;}
body {margin: 10px;}
li {margin: 25px;}
.unstyled, .imgPreview, .showPrice {float: left; width: 50%;}
.unstyled, .imgPreview img {max-width: 100%;}
p {margin: 5px;}
.recycle-button {
padding: 6px 6px;
background-color: rgb(53, 189, 208);
border-radius: 5px;
color: white;
margin-bottom: 0px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div style="margin-bottom: 35px;">
<h3>LIST</h3> </div>
<ul class="unstyled">
<li>List 1</li>
<li>List 2</li>
<li>List 3</li>
<li>List 4</li>
<li>List 5</li>
<li>List 6</li>
</ul>
<div class="imgPreview">
<img src="" alt="" width="350" height="150"/>
</div>
My goal is to have something like this.
Edit:
So far, I've tried adding the attribute data-price to the element <a to hold the price data:
<li>List 1</li>
and have the script do the same function with the imgPreview:
$(".imgPreview").show().find("p").attr($(this).attr("data-price"));
I'm fiddling with this and the error I get is "Script error." Surely, you can see the limited knowledge I have with JS.

May be you want something like this...
$(function () {
$(".imgPreview").hide();
$(".unstyled li a").click(function (event) {
var listItem = event.target.parentElement;
var image = $(".imgPreview");
image.show();
image.find("img").attr("src", $(this).attr("href"));
$(image.find("span"))[0].innerHTML="Price = $"+ ($( "li" ).index( listItem ) + 1);
return false;
});
$("body").click(function () {
$(".imgPreview").hide();
});
});
* {font-family: 'Segoe UI'; margin: 0; padding: 0; list-style: none;}
body {margin: 10px;}
li {margin: 25px;}
.unstyled, .imgPreview, .showPrice {float: left; width: 50%;}
.unstyled, .imgPreview img {max-width: 100%;}
p {margin: 5px;}
.recycle-button {
padding: 6px 6px;
background-color: rgb(53, 189, 208);
border-radius: 5px;
color: white;
margin-bottom: 0px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div style="margin-bottom: 35px;">
<h3>LIST</h3> </div>
<ul class="unstyled">
<li>List 1</li>
<li>List 2</li>
<li>List 3</li>

<li>List 6</li>
</ul>

jQuery sortable own element as placeholder

I'm implementing a connected list like a Kanban board. Everything works but the placeholder is still missing. I'm looking now for a way to add a the own element as placeholder like how they done it in Gitlab:
How can I do this? I know that there is a placeholder variable but I'm not sure how I can use the same element as placeholder. This is my code:
jQuery( document ).ready( function ( $ ) {
$( "#sortable1, #sortable2" ).sortable({
connectWith: ".connectedSortable"
}).disableSelection();
});
#sortable1, #sortable2 {
border: 1px solid #eee;
width: 142px;
min-height: 20px;
list-style-type: none;
margin: 0;
padding: 5px 0 0 0;
float: left;
margin-right: 10px;
}
#sortable1 li, #sortable2 li {
margin: 0 5px 5px 5px;
padding: 5px;
font-size: 1.2em;
width: 120px;
}

drag and drop functionality with click

I'm creating a very simple drag and drop application.
The drag and drop functionality using html5 works perfectly on desktop.
I want to replicate the functionality of drag and drop using click(select) and click(target, drop).
What I want to happen.
You click on the element you want to move (i.e with mouse or finger in mobile situation)
the element you've selected is stored in the dom and then on the next click (in a target area) the element is appended.
Is this achievable and how?
Thanks

I would achieve this by storing the reference to "clicked" items in a variable (list, object, whatever suits you) after you click on them. When you click on "drop" area (figuring out what the "drop area" is in any way you want) just read that variable and "move" (probably with CSS) all clicked items to "drop" area.

The example below is a simple drag and drop example:

As I mentioned above at the end of each Column the number of rows must be displayed and aside of each row numbering should be displayed.
1 worker1 1 worker8 1 worker14
2 worker2 2 worker10 2 worker13
3 worker3 3 worker11 3 worker15
4 worker4 4 worker12 total 3
5 worker5 total 4
6 worker7
7 worker6
8 worker9
Total 8

To do what you require you could wrap the ul elements in a div with another div under them to hold the total count of li elements within that container. You can then updated that total when an item is dropped using the stop property of the sortable plugin, like this:
$("ul.droptrue").sortable({
connectWith: "ul",
stop: function() {
$('.total').text(function() {
return 'Total: ' + $(this).closest('.container').find('li').length;
});
}
});
$("ul.dropfalse").sortable({
connectWith: "ul",
dropOnEmpty: false
});
$("#sortable1, #sortable2, #sortable3").disableSelection();
.container {
display: inline-block;
}
#sortable1,
#sortable2,
#sortable3 {
list-style-type: none;
margin: 0;
float: left;
margin-right: 10px;
background: #eee;
padding: 5px;
width: 143px;
}
#sortable1 li,
#sortable2 li,
#sortable3 li {
margin: 5px;
padding: 5px;
font-size: 0.8em; /* changed so the example fits in the snippet better*/
width: 120px;
}
