In semantic UI, when using the dropdown component, once you make a selection, it selects the word and appears as a keyword select as shown, allowing for multiple selections:
How can this be done with a text field that takes in any input, and after the user presses enter it will create a selection in the gray box similar to semantic ui? I need to allow this for multiple custom text inputs. Thanks in advance to anyone that can help.

Your description inspired me to implement this feature. Here's what I came up with:
function multiSearchKeyup(inputElement) {
if(event.keyCode === 13) {
inputElement.parentNode
.insertBefore(createFilterItem(inputElement.value), inputElement)
;
inputElement.value = "";
}
function createFilterItem(text) {
const item = document.createElement("div");
item.setAttribute("class", "multi-search-item");
const span = `<span>${text}</span>`;
const close = `<div class="fa fa-close" onclick="this.parentNode.remove()"></div>`;
item.innerHTML = span+close;
return item;
}
}
.multi-search-filter{
border:1px solid #DDD;
border-radius: 3px;
padding:3px;
min-height: 26px;
}
.multi-search-filter > input {
border: 0px;
outline: none;
font-size: 20px;
}
.multi-search-item {
margin: 2px;
padding: 2px 24px 2px 8px;
float: left;
display: flex;
background-color: rgb(204, 204, 204);
color: rgb(51, 51, 51);
border-radius: 3px;
position: relative;
}
.multi-search-item > span {
font-family: 'Muli';
line-height: 18px;
}
.multi-search-item > .fa {
font-size: 12px;
line-height: 18px;
margin-left: 8px;
position: absolute;
right: 8px;
top: 2px;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">
<link href="https://fonts.googleapis.com/css?family=Muli&display=swap" rel="stylesheet">
<div class="multi-search-filter" onclick="Array.from(this.children).find(n=>n.tagName==='INPUT').focus()">
<input type="text" onkeyup="multiSearchKeyup(this)">

How do I append data from localStorage to an element on the DOM

Currently working on a Bookmark manager that saves data to localstorage, then append the stored data from the localstorage to the DOM but the fetchUrl() doesn't append the code to the DOM.
Please find below what I have tried:
document.getElementById('subButton').addEventListener('click',storeFormInput)
var bookmarks= []
function storeFormInput(e){
e.preventDefault()
//get input values
var nameInput = document.getElementById('name').value;
var urlInput = document.getElementById('url').value;
//create a bookmark object
let bookmark = {
name: nameInput,
url: urlInput
}
// store bookmark in bookmarks array
bookmarks.push(bookmark);
localStorage.setItem('bookmarksKey',JSON.stringify(bookmarks));
fetchUrl()
}
function fetchUrl(){
var displayResult = document.getElementById('result');
var localDb = JSON.parse(localStorage.getItem('bookmarksKey'))
displayResult += localDb
}

<div id="displayResult">
<div id="saved">
<h3>SAVED BOOKMARK</h3>
</div>
<div id="result">
</div>
</div>
P.S I tried calling fetchUrl() on body load like
<body onload="fetchUrl()">
However, whenever I click the submit button, it doesn't append the localDb to the DOM until I refresh the page then it duplicates all the data stored in local storage in the DOM.

With this:
var displayResult = document.getElementById('result');
you get a reference to the dom element. So you can work with the dom element API . Display it in a simple way:
displayResult.innerHTML = '<pre>' + localStorage.getItem('bookmarksKey') + '</pre>'
But if you want to display it in a beatiful way, you have to go through your data and build element with the api.
So first study the api.

You can use below code snippet
window.onload = function() {
fetchUrl();
};
document.getElementById('subButton').addEventListener('click',storeFormInput)
var bookmarks= []
function storeFormInput(e){
e.preventDefault()
//get input values
var nameInput = document.getElementById('name').value;
var urlInput = document.getElementById('url').value;
//create a bookmark object
let bookmark = {
name: nameInput,
url: urlInput
}
// store bookmark in bookmarks array
bookmarks.push(bookmark);
localStorage.setItem('bookmarksKey',JSON.stringify(bookmarks));
fetchUrl()
}
function prepareHTML(data){
var str = ''
if(data.length){
str += '<table>'
for(var i=0; i<data.length; i++){
str += '<tr>'
str += '<td>' + data[i].name + '</td>'
str += '<td>' + data[i].url + '</td>'
str += '</tr>'
}
str += '</table>'
}
return str
}

I want to add a small box next to a question on a form I am asking which when clicked will pop up with a box of text for help about the question. How can i add some java script to create a Pop-up box that will appear when clicked rather than using on mouse over

Design it as you like.
Note that you can add several help popups. Just add class="help" and a title containing the help text.
var helpBox = document.getElementById("helpBox");
var helpElements = document.getElementsByClassName("help");
for (var i = 0; i < helpElements.length; i++) {
helpElements[i]._helpText = helpElements[i].title;
helpElements[i].removeAttribute("title");
helpElements[i].onclick = function(e) {
helpBox.style.display = "block";
helpBox.innerHTML = "<span id='close' title='Close'>X</span>" +
e.target._helpText;
helpBox.children[0].onclick = function() {
helpBox.style.display = "none";
}
}
}
body {
background-color: #f4f4f4;
font-family: sans-serif;
}
.help {
cursor: help;
}
#helpBox {
position: absolute;
top: 100px;
display: none;
width: 300px;
left: 50%;
margin-left: -150px;
border: 1px solid gray;
padding: 10px;
background-color: white;
z-index: 1000;
}
#helpBox #close {
float: right;
cursor: pointer;
background-color: red;
color: white;
padding: 0 6px;
}
<span class="help" title="Help text">Help</span>
<div id="helpBox"></div>

why this problem occurs.I am added a tag element(number) in Hoursdiv through
dynamically.but the problem is:- element is not added in proper way.after added 6
element, space created.
javascript code:-
for(var i=1 ; i<=12; i++) {
(function () {
var cc=i;
if(cc<=9)
cc='0'+i;
var _id1 = "time"+cc;
str1 += "<a id='"+_id1+"' class='hournum a_Cal' >"+cc+"</a>";
}());
}
css code (h2ooooooo edit note: I have no idea if 'a_cal' is actually in the css file, but I've kept it here in case):
'a_cal'
.a_Cal{
text-decoration: none;
color: black;
width: 18%;
height: 11%;
float: left;
border-radius: 4px;
}
.hournum{
padding:5px;
}
.hoursdiv{
border: 1px solid #6699FF;
position: absolute;
top: 25%;
left: 4%;
text-align: center;
color: red;
width: 45%;
height: 52%;
background-color: white;
}

Hm, I feel dirty looking at your code.
If your problem is that space on the right side of the container then let me explain what's going on.
The reason that space is there is because the 6th element is too wide to stay on the same "row", and it gets pushed down to the next row. The reason it's too wide is because of the combined use of %-width and padding in your css, which never ends well.
Illustration
I've constructed an example of how I think you want it to look.
I also cleaned your code a little ;)
Example | Code
In this example I use absolute values instead of percentages. The benefit from this is that I can calculate the exact width required for my container.
A link's width is the sum of the width + padding + margin + border:
40 + (5*2) + (2*2) + (1*2) = 56 px
And we want 5 links per "row"
56 * 5 = 280 px
So the container's width has to be at least 280px to fit 5 links per row.
CSS
.hournum{
text-decoration: none;
color: black;
width: 40px;
float: left;
padding: 0px 5px;
text-align: center;
color: red;
border-radius: 3px;
border: 1px solid black;
margin: 2px 2px;
}
.container{
position: absolute;
top: 10px;
left: 10px;
width: 280px;
background-color: white;
border: 1px solid #6699FF;
padding: 2px;
}
Javascript
var str = "";
for(var i=1 ; i<=12; i++){
var cc = i;
var row
if(i <= 9) cc = "0" + i
str += ''+cc+"";
}
document.body.innerHTML = '<div class="container">'+str+"</div>";

So I have a Javascript array of CSS selectors:
array is like the following: '.header', '#footer', '#nav', etc
I also have a div containing my site CSS as text (12,000 lines long):
<div id="all">
#nav
{
border: 1px solid;
color: black;
}
#footer
{
display: block;
}
</div>
I need to take each selector from the array and for its match in $('#all'), remove everything from the start of the selector to it's end bracket.
i.e.
// for each from the array
$('#all').find($(this));
// removes everything from selector to its end bracket
Can anyone advise? It's to remove unused site CSS. I've been stuck for a while. Appreciated!

Update: Added debug mode, input, and output.
Okay, I guess you have a bunch of CSS and you wanna remove a few rules. Let me assume these:
Each row has only one selector.
Each row starts with that selector.
Each row has one complete rule. i.e., selector {property: value;}
If the third option is not succeeding, there are a lot of CSS compressors, and you can use them to make this CSS:
#footer
{
display: block;
}
Into:
#footer { display: block; }
Now once you have this in a text file, you can do the manipulation using PHP or some good programming language. I do not recommend client side one. Say if you have PHP, and you have the set of rules here:
#nav { border: 1px solid; color: black; }
#footer { display: block; }
And you have your array:
$remove = array('.header', '#footer', '#nav');
You can use something like this:
<pre><?php
$debug = false;
$rules[] = ".header { border: 1px solid; color: black; }";
$rules[] = "#nav { border: 1px solid; color: black; }";
$rules[] = "#footer { display: block; }";
$rules[] = "#header { border: 1px solid; color: black; }";
$rules[] = ".nav { border: 1px solid; color: black; }";
$rules[] = ".footer { display: block; }";
$remove = array('.header', '#footer', '#nav');
$final = array();
foreach ($rules as $rule)
{
if ($debug) echo "Debug: ", var_dump(strpos($rule, " ")) . "\n";
if ($debug) echo "Debug: ", var_dump(substr($rule, 0, strpos($rule, " "))) . "\n";
if ($debug) echo "Debug: ", var_dump(in_array(substr($rule, 0, strpos($rule, " ")), $remove)) . "\n";
if ($debug) echo "---\n";
if ( !in_array(substr($rule, 0, strpos($rule, " ")), $remove) )
$final[] = $rule;
}
echo implode("\n", $final);
?></pre>
The above script includes a debug. If you set $debug to true, you can see the different stuffs being checked.
The input given to this is:
.header { border: 1px solid; color: black; }
#nav { border: 1px solid; color: black; }
#footer { display: block; }
#header { border: 1px solid; color: black; }
.nav { border: 1px solid; color: black; }
.footer { display: block; }
The output is:
#header { border: 1px solid; color: black; }
.nav { border: 1px solid; color: black; }
.footer { display: block; }
