How to match user input with array data in JavaScript - javascript

I'm new in learning HTML, JavaScript and CSS. I'm stuck at this JavaScript code.
I'm trying to match user input on the searchbar with some city array list I already prepared, when the search result match the script will change the display style of element into showing the result of their search value, but until now the result always showing false value.
Is there any better way to do this? Is there something wrong with my code?
function searchRespond() {
if (document.getElementById("myInput").value.match(cities))
{
document.getElementById("areaCovered").style.display = "block";
}
else {
document.getElementById("areaNotCovered").style.display = "block";
document.getElementById("searchResult").innerHTML = document.getElementById("myInput").value;
}
}
var cities = ["Banda Aceh", "Bandar Lampung", "Banyuwangi", "Bandung", "Bali", "Batam", "Batu", "Bekasi", "Bengkulu", "Binjai", "Blitar", "Bogor", "Bukittinggi", "Cimahi", "Cirebon", "Denpasar", "Depok", "Dumai", "Gunungsitoli", "Jakarta", "Jambi", "Kediri", "Langsa", "Lhokseumawe", "Lombok", "Lubuklinggau", "Madiun", "Magelang", "Malang", "Medan", "Metro", "Mojokerto", "Padang", "Padang Sidempuan", "Padangpanjang", "Pagar Alam", "Palembang", "Pangkal Pinang", "Pariaman", "Pasuruan", "Payakumbuh", "Pekalongan", "Pekanbaru", "Pematangsiantar", "Prabumulih", "Prigi", "Probolinggo", "Sabang", "Salatiga", "Sawahlunto", "Semarang", "Serang", "Sibolga", "Solo", "Subussalam", "Sukabumi", "Sumbawa", "Sungaipenuh", "Surabaya", "Surakarta", "Tangerang", "Tangerang Selatan", "Tanjungbalai", "Tanjungpinang", "Tasikmalaya", "Tebing Tinggi", "Tegal", "Yogyakarta"];

To do what you require you can use filter() to match the user's input to values in your array. You would be best to perform a case-insensitive match, which can be done by converting both values to the same case.
Note that this logic sets the notifications as hidden before the logic runs, so that the previous state of the search is removed.
In addition, I made a couple of improvements to the code. Firstly I stored the relevant elements in variables instead of accessing the DOM every time. This is slightly more performant, and makes the code a lot easier to read. I also used addEventListener() to bind events instead of inline event handlers in the HTML, which are bad practice and shouldn't be used. Lastly I converted the <h> elements to <h2 /> in this demo, as there is no <h> element in HTML.
const input = document.querySelector('#myInput');
const areaCovered = document.querySelector('#areaCovered');
const areaNotCovered = document.querySelector('#areaNotCovered');
const searchResult = document.querySelector('#searchResult');
const fillArea = document.querySelector('#fillArea');
const cities = ["Banda Aceh", "Bandar Lampung", "Banyuwangi", "Bandung", "Bali", "Batam", "Batu", "Bekasi", "Bengkulu", "Binjai", "Blitar", "Bogor", "Bukittinggi", "Cimahi", "Cirebon", "Denpasar", "Depok", "Dumai", "Gunungsitoli", "Jakarta", "Jambi", "Kediri", "Langsa", "Lhokseumawe", "Lombok", "Lubuklinggau", "Madiun", "Magelang", "Malang", "Medan", "Metro", "Mojokerto", "Padang", "Padang Sidempuan", "Padangpanjang", "Pagar Alam", "Palembang", "Pangkal Pinang", "Pariaman", "Pasuruan", "Payakumbuh", "Pekalongan", "Pekanbaru", "Pematangsiantar", "Prabumulih", "Prigi", "Probolinggo", "Sabang", "Salatiga", "Sawahlunto", "Semarang", "Serang", "Sibolga", "Solo", "Subussalam", "Sukabumi", "Sumbawa", "Sungaipenuh", "Surabaya", "Surakarta", "Tangerang", "Tangerang Selatan", "Tanjungbalai", "Tanjungpinang", "Tasikmalaya", "Tebing Tinggi", "Tegal", "Yogyakarta"];
document.querySelector('#search-from').addEventListener('submit', e => {

You can use javascript includes().
<script>
const fruits = ["Banana Aceh", "Orange", "Apple", "Mango"];
let str = "Banana Aceh"; //document.getElementById("myInput").value
if(fruits.some(v => str.includes(v))) {
console.log("Exists");
} else {
console.log("Did not Exists");
}
</script>


function searchRespond() {
let searchTerm = document.getElementById("myInput").value;
if (cities.find(city => city == searchTerm))
{
document.getElementById("areaCovered").style.display = "block";
}
else {
document.getElementById("areaNotCovered").style.display = "block";
document.getElementById("searchResult").innerHTML = document.getElementById("myInput").value;
}
}
var cities = ["Banda Aceh", "Bandar Lampung", "Banyuwangi", "Bandung", "Bali", "Batam", "Batu", "Bekasi", "Bengkulu", "Binjai", "Blitar", "Bogor", "Bukittinggi", "Cimahi", "Cirebon", "Denpasar", "Depok", "Dumai", "Gunungsitoli", "Jakarta", "Jambi", "Kediri", "Langsa", "Lhokseumawe", "Lombok", "Lubuklinggau", "Madiun", "Magelang", "Malang", "Medan", "Metro", "Mojokerto", "Padang", "Padang Sidempuan", "Padangpanjang", "Pagar Alam", "Palembang", "Pangkal Pinang", "Pariaman", "Pasuruan", "Payakumbuh", "Pekalongan", "Pekanbaru", "Pematangsiantar", "Prabumulih", "Prigi", "Probolinggo", "Sabang", "Salatiga", "Sawahlunto", "Semarang", "Serang", "Sibolga", "Solo", "Subussalam", "Sukabumi", "Sumbawa", "Sungaipenuh", "Surabaya", "Surakarta", "Tangerang", "Tangerang Selatan", "Tanjungbalai", "Tanjungpinang", "Tasikmalaya", "Tebing Tinggi", "Tegal", "Yogyakarta"];

suggest to validate input by making first letter uppercase and rest lowercase to match the array values
with javascript indexOf function
function searchRespond() {
var input = document.getElementById("myInput").value;
var area2search = input.charAt(0).toUpperCase() + input.slice(1).toLowerCase(); /* make fist letter capital and rest lower case to match array */
if (cities.indexOf(area2search) > -1) {
document.getElementById("areaCovered").style.display = "block";
//In the array!
} else {
document.getElementById("areaNotCovered").style.display = "block";
document.getElementById("searchResult").innerHTML = document.getElementById("myInput").value;
}
}
var cities = ["Banda Aceh", "Bandar Lampung", "Banyuwangi", "Bandung", "Bali", "Batam", "Batu", "Bekasi", "Bengkulu", "Binjai", "Blitar", "Bogor", "Bukittinggi", "Cimahi", "Cirebon", "Denpasar", "Depok", "Dumai", "Gunungsitoli", "Jakarta", "Jambi", "Kediri", "Langsa", "Lhokseumawe", "Lombok", "Lubuklinggau", "Madiun", "Magelang", "Malang", "Medan", "Metro", "Mojokerto", "Padang", "Padang Sidempuan", "Padangpanjang", "Pagar Alam", "Palembang", "Pangkal Pinang", "Pariaman", "Pasuruan", "Payakumbuh", "Pekalongan", "Pekanbaru", "Pematangsiantar", "Prabumulih", "Prigi", "Probolinggo", "Sabang", "Salatiga", "Sawahlunto", "Semarang", "Serang", "Sibolga", "Solo", "Subussalam", "Sukabumi", "Sumbawa", "Sungaipenuh", "Surabaya", "Surakarta", "Tangerang", "Tangerang Selatan", "Tanjungbalai", "Tanjungpinang", "Tasikmalaya", "Tebing Tinggi", "Tegal", "Yogyakarta"];

Modifying JS pager - how to substitute html elements using JQuery

Here is the initial code:
<div class="fs-table-table">
<div class="fs-table-row header">
<div class="fs-table-cell">
Course Name
</div>
<div class="fs-table-cell">
Lessons
</div>
</div>
<div id="fs-table-content">
</div>
</div>
Now the pager file calls:
$('#' + options.contentHolder).html(template(pager, options.template, options.currentData, options.startPage, options.perPage, options.alwaysShowPager, options.informationToShow, options.errorTemplate));
where contentHolder is 'fs-table-content', and it points to a template:
<script type="text/template" id="weeklyLessonTemplate">
<div class="fs-table-row">
<div class="fs-table-cell" data-title="Course Name">
##courseName##
</div>
<div class="fs-table-cell" data-title="Lesson">
<input type="radio" class="radio" name="weekly_lesson" value="##lessons##" />
<label for="##lessons##">##lessons##
</label>
</div>
</div>
</script>
and it yields:
<div class="fs-table-table">
<div class="fs-table-row header">
<div class="fs-table-cell">
Course Name
</div>
<div class="fs-table-cell">
Lessons
</div>
</div>
<div class="fs-table-row">
<div class="fs-table-cell" data-title="Course Name">
Art/Music/Social Media
</div>
<div class="fs-table-cell" data-title="Lesson">
<input type="radio" class="radio" name="weekly_lesson" value="What is art?">
<label for="What is art?">What is art?
</label>
</div>
</div>
</div>
So you see, calling the function "template" simply returns html code. Now, when I click on the next page number, I expect the html to change but it doesn't change, it stays the same because
<div id="fs-table-content">
</div>
has been replaced. How do I inject fs-table-content back into the code. It should be put in the page onclick code:
$('#' + pager).on('click', '.page, .last-page, .first-page, .next-pages, .prev-pages', function(e) {
var newPage = parseInt($(this).data('value'));
var perPage = parseInt($('#' + pager + ' .perPage').val());
$('#' + pager + ' .page.current').removeClass('current');
$('#' + pager + ' .page[data-value="' + newPage + '"]').addClass('current');
showProperPaging(pager, newPage, options.totalPages, options.pagesToShow);
$('#' + options.contentHolder).html(template(pager, options.template, options.currentData, newPage, perPage, options.alwaysShowPager, options.informationToShow, options.errorTemplate));
options.currentPage = newPage;
$('#' + pager).trigger("pagingChange");
});
I noticed that in the demo for the pager, they use the following line to change the html:
var showing = $('#' + templateToShow).html().format(data);
html += showing;
But my data is structured differently, I don't think I can use .format

The way this script has been designed is that you need to provide two separate divs (not nested within one another). One for your content and one of its content (where it places pagination, search .. etc).
So you can change your code to this for it work:
!function(a){function e(e,t,r,n,o,s,g){var p="",l=Math.ceil(t/r);p+='<div class="showing"></div>',p+='<div class="pager"><span class="first-page btn" data-value="1">First</span><span class="prev-page btn">Previous</span><span class="prev-pages btn" data-value="1">...</span><span class="page btn current" data-value="1">1</span>';for(var i=1;i<l;i++)p+='<span class="page btn" data-value="'+(i+1)+'">'+(i+1)+"</span>";p+='\t<span class="next-pages btn" data-value="6">...</span><span class="next-page btn">Next</span><span class="last-page btn" data-value="'+l+'">Last</span></div>',p+='<div class="options" style="text-align: center; margin-bottom: 10px;"><span>Show </span><select class="perPage">';for(i=0;i<n.length;i++)n[i]==r?p+='<option selected="selected">'+n[i]+"</option>":p+="<option>"+n[i]+"</option>";p+="\t</select><span> per page</span></div>",s&&(p+='<div class="searchBox"><input type="text" class="search" placeholder="Search"

jQuery/JS: delete object from array and DOM

I am learning JS and jQuery. As an exercise, I am trying to create a basic contact list. I need to be able to add and delete contacts from the list.
But I am having some bugs in my result. I can't find the cause of it. If anyone can advise? I would be most gratefull.
BUG 1:
When running the snippet below, you will see some sample contacts generated in the list. You can delete a contact just fine. You can also add a contact. But after adding a contact, the delete buttons stop working.
First I thought the issue was probably a missing character in my .html() method on the contacts objects. But I see no errors there. Anyone?
BUG 2:
Inside the $renderContacts function. You can see the const html. This should replace the let html and for loop below. And it works for long list of contacts. But the first contact is rendered as [object Object]. I don't see the cause. Might these 2 bugs be related?
Please advise.
Many thanks! :)

BUG1:
You can't fire on click function on dynamically generated DOM element like that.
Add event listener to your element (using pure JS):
elem.addEventListener("click", func, false);
Or change syntax of your click function to this (using jQuery):
$(document).on("click",'.delete-contact', (event) => {
// your code here
});
BUG2:
I don't know why this function acts like that, but you always have to pass default string parameter. Look to the next lines I made:
let html = arr.reduce((all, one) => all += one.toHTML(), '');

Changing the colour of the input field focus using JavaScript

I am implementing an HTML input field where the user has to enter his email address. I am also implementing validation on the same input field using JavaScript.
function validateEmail() {
var email = document.getElementById('EmailTextbox');
var errorMessage = document.getElementById('ErrorMessageJumbotron');
var filter = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (!filter.test(email.value)) {
errorMessage.style.display = 'block';
email.style.color = '#E54A49';
email.style.border = "1px solid #E54A49";
} else {
errorMessage.style.display = 'none';
email.style.border = "1px solid #949494";
email.style.color = 'black';
}
}
* {
font-family: 'Poppins', sans-serif;
}
#EmailTextbox {
margin-bottom: 15px;
}
input[type="text"] {
font-size: 1em;
height: 45px;
width: 100%;
border: 1px solid #949494;
}
<div class="container">
<div class="jumbotron" id="ErrorMessageJumbotron" style="display: none;">
<div id="errorMessage">
<i class="fa fa-exclamation-triangle fa-2x" aria-hidden="true">
<span style="font-family: 'Poppins', sans-serif; font-weight: 500;">Please correct the marked fields.</span>
</i>
</div>
</div>
</div>
<!--container-->
<div class="container jumbotron">
<input type="text" onblur="validateEmail()" id="EmailTextbox" placeholder="E-mail address" class="form-control">
</div>
If the email is incorrect, the border of the input field is set to red and the user is prompted to enter a valid email address. However, when the user clicks on the input field, the focus is coloured blue and I want it red for this particular case. Otherwise, I want it to be blue as the default.
I have tried several approaches to try to change the focus colour using JavaScript but I did not manage to get it working properly.

Here is a simplified version of what you are trying to do, to help you achieve your end goal:
HTML
<input onblur="onEmailInputBlur(event)" placeholder="E-mail address">
CSS
input.is-invalid {
border: 1px solid red;
outline: none;
}
JS
var invalidClass = 'is-invalid';
function onEmailInputBlur(event) {
var email = event.target.value,
elClassList = event.target.classList;
elClassList.remove(invalidClass);
if (!isEmailValid(email)) {
elClassList.add(invalidClass);
}
}
function isEmailValid(email) {
var validEmailRegex = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
return validEmailRegex.test(email);
}

why my h1 title hides behind input box when slideUp executes

I have the following page, which is a wikisearch page that queries multiple wikipidia pages for the search term. The page has the title and input box somewhere around the middle; however, when I click on the botton, the title slides up, and so the input box. But the input box slides all way up covering the title. I think!... how can I prevent the inputbox from covering the title? or make the title stays at the top of page? Thanks
$(document).ready(function() {
//bringing focus to search box
window.load = function() {
document.getElementById("search-box").focus();
};
//listener for search button
$("#search").click(function() {
$("#title").slideUp(3000);
// $("#title").css("text-align", "left");
search();
});
function search() {
//grabbing the id of search result div
var srchResult = document.getElementById("results");
//string entered by user for search
var searchStr = document.getElementById("search-box").value;
//replace space with _ in search query
searchStr = searchStr.replace(" ", "_");
console.log(searchStr);

showError(searchStr);
} else {
displayResults(response);
}
},
error: function() {
alert("Something went wrong.. <br>" +
"Try again!");
}
});
function displayResults(response) {
console.log(response.query);
var search = response.query.search;
var srchLength = response.query.search.length;
srchResult.innerHTML = "";
// console.log(srchResult.innerHTML);
//pulling title and searchbox to top
// $("#title").css("margin-top:", "10px !important");
for (var i = 0; i < srchLength; i++) {
srchResult.innerHTML += '<div class="output"><h4>' + search[i].title + ' </h4><p>' + search[i].snippet + '</p></div>';

Insted of using $('#title').slideUp(3000) try use $('#title').animate({'margin-top': '0'}, 3000);
Then the title will remain.
Also, you might want to remove onclick="#" from <button id="search" class="btn btn-primary" onclick="#">Search</button>
Example below.
$(document).ready(function() {

window.load = function() {

Add this to the h1 class
h1 {
z-index: 1000;
}
Now let's say you needed something to then go on top of the header, you'd give that element's class a z-index of something higher than 1,000, so maybe 1,001! If you needed something to go behind, simply make it 999 or lower. Using 1,000 gives you a lot of free range in either direction (+/-) to work with.

Values not getting saved onsubmit of form using local storage

I want to capture 2 values (product name and energy consumption)from a form and store it using local Storage.
OnClick I want to display the stored values on the side of the form.
What is working
local storage is getting set.
Issues (in the commented function compareSetup)
1) My guess is I am not getting the selected product nor the energy values from the form itself.
2) wrote the display logic but getting error on that line
Uncaught SyntaxError: Unexpected identifier.
I tried 2 different ways. I am newbie hence trying different syntax
3) Resources tab in Chrome shows
callAnnual as undefined
callProduct as 0
4) alerts inside function did not work
I missing something. either logically or syntaxwise or both.
Can some one guide me please. Thanks for your time.
