Randomly assign list items to Columns

I have a drag and drop program, the code is down below. Now, I have been trying for a while to get my 'Simulate to the next round!' to take .node7, .node8, .node9, .node10, .node11, & .node12 id's of some of the li's and randomly assign one to each column, or 'Team'. Anything would help! Here is a JSFiddle, and here is a snippet:

var boxSizeArray = [14,14,14,14,14,14]; // Array indicating how many items there is rooom for in the right column ULs
var arrow_offsetX = -5; // Offset X - position of small arrow
var arrow_offsetY = 0; // Offset Y - position of small arrow
var arrow_offsetX_firefox = -6; // Firefox - offset X small arrow
var arrow_offsetY_firefox = -13; // Firefox - offset Y small arrow
var verticalSpaceBetweenListItems = 3; // Pixels space between one <li> and next
// Same value or higher as margin bottom in CSS for #dhtmlgoodies_dragDropContainer ul li,#dragContent li

Implying that you change id="Available Players" to id="AvailablePlayers", that should work:
function shufflePlayers(amount=6) {
var box = 1;
var rnd = 0;
for(var i = 0; i < amount; i++) {
rnd = Math.floor((Math.random()*$('#AvailablePlayers li').length));
$('#AvailablePlayers').children('li').eq(rnd).appendTo('#box'+box);
if(box == 6) {
box = 1;
} else {
box++;
}
}
}
EDIT: Fixed the function being able to shuffle >6 players, also moved the declarations outside of the loop.
EDIT 2: Here's a version that accepts an array of team container IDs as a parameter:
function shufflePlayers(amount=6, teamsID=['box1', 'box2', 'box3', 'box4', 'box5', 'box6']) {
var box = 0;
var rnd = 0;
for(var i = 0; i < amount; i++) {
rnd = Math.floor((Math.random()*$('#AvailablePlayers li').length));
$('#AvailablePlayers').children('li').eq(rnd).appendTo('#'+teamsID[box]);
if(box == teamsID.length) {
box = 0;
} else {
box++;
}
}
}
As is, this modified function will work without any parameters, but if you change the team boxes ids, then you need to pass them as an array: shufflePlayers(6, ['Red', 'Green', 'Blue', 'Cyan', 'Magenta', 'Yellow'])
EDIT 3: Another version of the function, this time it only picks random players from the first set with the size of amount (default is 6).
function shufflePlayers(amount=6, teamsID=['box1', 'box2', 'box3', 'box4', 'box5', 'box6']) {
var box = 0;
var rnd = 0;
for(var i = 0; i < amount; i++) {
rnd = Math.floor((Math.random()*(amount-i)));
$('#AvailablePlayers').children('li').eq(rnd).appendTo('#'+teamsID[box]);
if(box == teamsID.length) {
box = 0;
} else {
box++;
}
}
}

Using localStorage to get my Save Button to Work

In my program you can drag and drop players into different teams. If you were to drag 'Player A' into the 'Team D' column. How can I manipulate localStorage, or any other function, to save which team I assigned the players to when I click the 'Save' button at the bottom?
Note: The code doesn't work in the Snippet, it only works if you copy it and save it as a HTML file and then run it on your Browser.

You can easily use "Web SQL" to deal with this case
this a small introduction about usage of "Web SQL"
var db = openDatabase('mydb', '1.0', 'my first database', 2 * 1024 * 1024);
db.transaction(function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS players (id unique, text)');
tx.executeSql('INSERT INTO players (id, text) VALUES (1, "A")');
tx.executeSql('SELECT * FROM players', [], function(tx, results) {
var len = results.rows.length;
for (var i = 0; i < len; i++) {
alert(results.rows.item(i).text);
}
});
});
Very good tutorial about "Web SQL" from HERE

How to loop a JavaScript nodelist and apply a JavaScript style?

How can I get the JavaScript loop associated with the liList variable to effect the DOM whist not over-riding any other styles?
I would like my menu items to still be orange and for the first list item to hold onto the styleAbbr variable that was created in JavaScript.
//JavaScript style to effect HTML abbr
var styleAbbr = document.createElement('style');
styleAbbr.type = 'text/css';
styleAbbr.innerHTML = '.myAbbr {font-style: italic; letter-spacing: .4em;}';
document.getElementsByTagName('head')[0].appendChild(styleAbbr);
document.querySelector('abbr').className = 'myAbbr';
//the JavaScript for the loop
var msg = '';
var i = 0;
var liList = document.querySelectorAll('li.menuItem');
if (i < liList.length) {
for (var i = 0; i < liList.length; i++) {
//liList[i].textContent gets the text form the li element in the DOM
var listWording = liList[i].textContent;
//liList.innerHTML applies my style and pushes listWording into the DOM
msg += '<li style="background: red; margin-top: 10px;">'
+ listWording
+ '</li>';
}
}
//I believe that the issue is that .innerHTML = msg.
document.getElementById('mMain').innerHTML = msg;
ul {
font-size: 1.4em;
list-style: none;
}
ul li a {
text-decoration: none;
color: #e69b1e;
}
<ul id="mMain">
<li class="menuItem">
<a href="#">
<abbr title="HyperText Markup Language">HTML</abbr>
</a>
</li>
<li class="menuItem">
About
</li>
<li class="menuItem">
Gallery
</li>
<li class="menuItem">
Contact
</li>
</ul>
Ideally I would like to have my JavaScript style in its own variable and loop that into the "menuItem" class whilst not effecting any other predefined class's however I am not quite sure how I would call that variable into a loop.
var menuItemClass = document.createElement('style');
menuItemClass.type = 'text/css';
menuItemClass.innerHTML = '.menuStyle {background: red; margin-top: 10px;}';
document.getElementsByTagName('head')[0].appendChild(menuItemClass);
Im also aware I could have a class in my CSS do all of this and then reference that.
However I am interested how this can be achieved in JavaScript.
Thank you.

I found a solution to referencing my JavaScript defined style.
var styleAbbr = document.createElement('style');
styleAbbr.type = 'text/css';
styleAbbr.innerHTML = '.myAbbr {font-style: italic; letter-spacing: .4em;}';
document.getElementsByTagName('head')[0].appendChild(styleAbbr);
document.querySelector('abbr').className = 'myAbbr';
var menuItemClass = document.createElement('style');
menuItemClass.type = 'text/css';
menuItemClass.innerHTML = '.menuStyle {background: red; margin-top: 10px;}';
document.getElementsByTagName('head')[0].appendChild(menuItemClass);
var msg = '';
var i = 0;
var liList = document.querySelectorAll('li.menuItem');
if (i < liList.length) {
for (var i = 0; i < liList.length; i++) {
liList[i].className = 'menuStyle';
}
}
ul li {
font-size: 1.4em;
list-style: none;
}
ul li a {
text-decoration: none;
color: #e69b1e;
}
<ul id="mMain">
<li class="menuItem">
<a href="#">
<abbr title="HyperText Markup Language">HTML</abbr>
</a>
</li>
<li class="menuItem">
About
</li>
<li class="menuItem">
Gallery
</li>
<li class="menuItem">
Contact
</li>
</ul>

I am answering how to add class to each li element created dynamically without effecting predefined. So create class according to the menu item innerText and take background color for the class from array defined colors
//JavaScript style to effect HTML abbr
var styleAbbr = document.createElement('style');
styleAbbr.type = 'text/css';
styleAbbr.innerHTML = '.myAbbr {font-style: italic; letter-spacing: .4em;}';
document.getElementsByTagName('head')[0].appendChild(styleAbbr);
document.querySelector('abbr').className = 'myAbbr';
//the JavaScript for the loop
var msg = '';
var i = 0;
var liList = document.querySelectorAll('li.menuItem');
//defining background colours
var colors = ['red', 'orange', 'green', 'brown', 'blue'];
var j = 0;
if (i < liList.length) {
for (var i = 0; i < liList.length; i++) {
//creating class as the innerText content
if (j >= colors.length) {
j = 0
}
var menuItemClass = document.createElement('style');
menuItemClass.type = 'text/css';
menuItemClass.innerHTML = '.' + liList[i].innerText + ' {background: ' + colors[j] + '; margin-top: 10px;}';
document.getElementsByTagName('head')[0].appendChild(menuItemClass);
j++;
//liList[i].textContent gets the text form the li element in the DOM
var listWording = liList[i].textContent;
//liList.innerHTML applies my style and pushes listWording into the DOM
if (i == 0) {
msg += liList.innerHTML =
'<li class="myAbbr ' + listWording + '">' +
listWording +
'</li>';
} else {
msg += liList.innerHTML =
'<li class=" ' + listWording + '">' +
listWording +
'</li>';
}
}
}
//I believe that the issue is that .innerHTML = msg.
document.getElementById('mMain').innerHTML = msg;
ul {
font-size: 1.4em;
list-style: none;
}
ul li a {
text-decoration: none;

How to enable the active item to selected in dropdown in the pages when its onload

converting this UL to dropdown
<ul class="list-group showdiv">
<li class="list-group-item {{{ (Request::is('developmentService') ? 'active' : '') }}}">Bespoke Software Development</li>
<li class="list-group-item {{{ (Request::is('UserExperienceService') ? 'active' : '') }}}">User Experience Design</li>
<li class="list-group-item {{{ (Request::is('StaffService') ? 'active' : '') }}}">Staff Augmentation</li>
<li class="list-group-item {{{ (Request::is('TestingService') ? 'active' : '') }}}">Testing and Validation</li>
<li class="list-group-item {{{ (Request::is('GamingService') ? 'active' : '') }}}">Gaming</li>
</ul>
To convert Dropdown
Converting ul by this script.
<script type="text/javascript"> $(function() {
$('ul.showdiv').each(function() {
var $select = $('<select />');
$(this).find('a').each(function() {
var $option = $('<option />');
$option.attr('value', $(this).attr('href')).html($(this).html());
$select.append($option);
});
$(this).replaceWith($select);
});
$('select').on('change', function (e) {
var valueSelected = this.value;
window.location.href = valueSelected; }); });
How to enable the "active" item to "selected=true" in dropdown in the pages.
** its always getting selected the first item in the dropdown list

Maybe something like this works: (inside the each loop)
$('ul.showdiv').each(function() {
var $select = $('<select />');
$(this).find('a').each(function() {
var $option = $('<option />');
$option.attr('value', $(this).attr('href')).html($(this).html());
if($(this).children().hasClass('active')){
$option.prop('selected', true);
}
$select.append($option);
});
$(this).replaceWith($select);
});

What about something like this? I know it changes your code a bit, but it works. Just change the filenames accordingly.
Example of a filename that should be used: "userExperienceDesign.html" in order to make sure that the navigation menu works correctly
Just erase the following line when running it from your own files: filename = "item3.html";
jsfiddle
//URL to id to select active link
var href = window.location.href;
var filename = href.split('/').pop();
filename = "item3.html";
//Example of a filename that should be used: "staffAugmentation.html" in order to make sure that the navigation menu works correctly
filename = filename.replace(/\..+$/, '');
$("#nav_" + filename).children("*").addClass("active");
if ($("#nav_" + filename).parent().parent("li")) {
$("#nav_" + filename).parent().parent().children("*").addClass("active");
}
//Fix subMenu widths: min width same as parent nav item and if right side of subMenu item surpasses parent ul's width, left offset compensates
var navWidth = $("#nav").width();
var navLeft = $("#nav").offset().left;
var navTotal = navWidth + navLeft;
var subMenus = $("#nav").children("li").children("ul");
for (var i = 0; i < subMenus.length; i++) {
var subMenu = subMenus.eq(i);
subMenu.parent().children("span").css({"padding-right":30+"px"});
subMenu.parent().addClass("hasSubMenu");
subMenu.children("li").css({
"min-width": subMenu.parent().width() - 5 + "px"
});
var subMenuWidth = subMenu.width();
var subMenuLeft = subMenu.offset().left;
var subMenuTotal = subMenuWidth + subMenuLeft;
if (navTotal < subMenuTotal) {
var newOffsetLeft = navTotal - subMenuTotal;
subMenu.css({
"left": subMenuLeft + newOffsetLeft + "px"
});
}
}
$("#nav").click(function () {
if ($(this).find("span").length > 0) {
$(this).find("ul").toggle();
}
});

How to sort a list with two items

Hello I want to make this two items sortable without using plugins and stuff, only HTML5 and pure javascript:
<ul ondragenter="return dragEnter(event)" ondrop="return dragDrop(event)"
ondragover="return dragOver(event)">
<li draggable="true" ondragstart="return dragStart(event)">Item 1</li>
<li draggable="true" ondragstart="return dragStart(event)">Item 2</li>
</ul>
well i've tried:
function dragStart(ev) {
ev.dataTransfer.effectAllowed = 'move';
ev.dataTransfer.setData("Text", ev.target.getAttribute('class'));
return true;
}
function dragEnter(ev) {
event.preventDefault();
return true;
}
function dragOver(ev) {
return false;
}
function dragDrop(ev) {
var src = ev.dataTransfer.getData("Text");
ev.target.appendChild(document.getElementById(src));
ev.stopPropagation();
return false;
}

Would you like to order alphabetically? Here is a solution without any library.
var items = document.getElementsByTagName("li");
var values = [];
for(var i = 0; i < items.length; i++) {
values.push(items[i].innerHTML);
}
values.sort();
for(var i = 0; i < items.length; i++) {
items[i].innerHTML = values[i];
}
