Adding a script for search functionality in the webpage - javascript

I am trying to add a script for the search filter and having an error in implementing it. Please let me know where I am wrong
I have added the search bar using the code
<input class="form-control" id="myInput" type="text" placeholder="Search for the courses">
and after that I added the script inside the body tag
$(document).ready(function() {
$("#myInput").on("keyup", function() {
var value = $(this).val().toLowerCase();
$("#myTable h4").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<header class="my-4">
<h1 class="display-3">Welcome to Open Academy</h1>
</header>
<input class="form-control" id="myInput" type="text" placeholder="Search for the courses">
<div class="row text-center" id="myTable">
<div class="col-lg-3 col-md-6 mb-4">

You need to show something higher than what you are currently finding.
You cannot hide the cards and then try to show the H4 inside the card.
Access $("#myTable .card") instead
Also you abuse a side effect of filter - Either filter on content or toggle on content
If the wrapping div is not hidden, you will get a scattering. So now I toggle the hidden wrapper instead
$(document).ready(function() {
$("#myInput").on("input", function() {
var value = $(this).val().toLowerCase();
$("#myTable .card").each(function() {
$(this).parent().toggle(
$.trim(value)!="" && $(this).text().toLowerCase().indexOf(value) > -1
)
});
});
});
#myTable>div { display:none; float:left; border:1px solid grey; margin:5px; padding:5px}

You are toggling the h4 instead of the .card that contains it.
You also do not need to toggle while filtering. Filter the ones you want and show them in one go. If you want to go one-by-one then use the .each instead of the .filter
$(document).ready(function() {
$("#myInput").on("input", function() {
var value = $(this).val().toLowerCase();
var allCards = $('#myTable .card');
allCards
.hide() // hide all cards
.filter(function() { // filter the cards that match
var h4text = $(this).find('h4').text().toLowerCase();
return h4text.indexOf(value) > -1;
}).show() // show the filtered cards
});
});

I hope I got your point and answered correctly. If not please mention in comment

I'm able to change the image of a card when it is being hovered over. But how do I do this for a large number of cards with different images

Here is an html sample for one card:
<div class="col s4">
<div class="card">
<div class="card-image">
<img src="img/forZane/Bowl_Andrew (1).jpg" onmouseover="hover(this);" onmouseout="unhover(this);">
</div>
<div class="card-content">
<h4 class="md-font">ceramic one.</h4>
<p class="md-font">$50.</p>
</div>
</div>
</div>
and this is the javascript that i'm using:
element.setAttribute('src', 'img/forZane/Bowl_Andrew (2).jpg');
}
function unhover(element) {
element.setAttribute('src', 'img/forZane/Bowl_Andrew (1).jpg');
}
I can't figure out how to apply this function/hover technique to different cards with different images.
Any help would be greatly appreciated.

You can add custom data-* attributes to your img tags, so that your hover/unhover functions can change the image in each case.
Take this for example:
function hover(element) {
element.setAttribute('src', element.getAttribute('data-hover'));
}
function unhover(element) {
element.setAttribute('src', element.getAttribute('data-unhover'));
}
<div class="col s4">
<div class="card">
<div class="card-image">
<img src="img (1).jpg" data-hover="img (2).jpg" data-unhover="img (1).jpg" onmouseover="hover(this);" onmouseout="unhover(this);">
</div>
<div class="card-content">
<h4 class="md-font">ceramic one.</h4>
<p class="md-font">$50.</p>
</div>
</div>
</div>
<div class="col s4">
<div class="card">
<div class="card-image">
<img src="img (1).jpg" data-hover="img (2).jpg" data-unhover="img (1).jpg" onmouseover="hover(this);" onmouseout="unhover(this);">
</div>
<div class="card-content">
<h4 class="md-font">ceramic one.</h4>
<p class="md-font">$50.</p>
</div>
</div>
</div>
If your filenames are indeed in a consistent format, and all you need to do is switch between filenames ending in "(1)" and "(2)", consider the following alternative.
Here, we remove the data-* attributes, and instead do a replacement of the src attribute.
function hover(element) {
element.setAttribute('src', element.getAttribute('src').replace('(1)', '(2)'));
}
function unhover(element) {
element.setAttribute('src', element.getAttribute('src').replace('(2)', '(1)'));
}
<div class="col s4">
<div class="card">
<div class="card-image">
<img src="img (1).jpg" onmouseover="hover(this);" onmouseout="unhover(this);">
</div>
<div class="card-content">
<h4 class="md-font">ceramic one.</h4>
<p class="md-font">$50.</p>
</div>
</div>
</div>
<div class="col s4">
<div class="card">
<div class="card-image">
<img src="img (1).jpg" onmouseover="hover(this);" onmouseout="unhover(this);">
</div>
<div class="card-content">
<h4 class="md-font">ceramic one.</h4>
<p class="md-font">$50.</p>
</div>
</div>
</div>

You can do this for multiple images by introducing a new parameter to your functions that set the image url to that value:
function hover(element, url)
element.setAttribute('src', url);
}
function unhover(element, url) {
element.setAttribute('src', url);
}
<div class="col s4">
<div class="card">
<div class="card-image">
<img src="img/forZane/Bowl_Andrew (1).jpg" onmouseover="hover(this, 'img/forZane/Bowl_Andrew (2).jpg');" onmouseout="unhover(this, 'img/forZane/Bowl_Andrew (1).jpg');">
</div>
<div class="card-content">
<h4 class="md-font">ceramic one.</h4>
<p class="md-font">$50.</p>
</div>
</div>
<div class="card">
<div class="card-image">
<img src="img/AnotherImage.jpg" onmouseover="hover(this, 'img/AnotherImageHover.jpg');" onmouseout="unhover(this, 'img/AnotherImage.jpg');">
</div>
<div class="card-content">
<h4 class="md-font">wodden one.</h4>
<p class="md-font">$70.</p>
</div>
</div>
</div>
That way, you can have the same effect among multiple images.

col-md-4 property in bootstrap 4 not working in my ejs file

<div class="container">
<div class="row card-deck">
<% for(var i=0;i<campgrounds.length;i++){ %>
<div class="card col-12 col-md-4">
<img class="card-image-top" src="<%= campgrounds[i].image %>" style=width:100%;height:350px;>
<div class="card-body">
<h3 class="card-title"><%= campgrounds[i].name %></h3>
</div>
</div>
<% }%>
</div>
</div>
Here "campgrounds" is a dictionary array with 2 properties("name" and image source). Now this array has 6 items and my col-md-4 should give 3 items in a row in resolutions of medium and above. But, this is not working and there are 12 items in a single row when in large/medium resolutions. Why?

.card in Bootstrap has its own flex properties which override .col-*
You need to add .card as a child div of .col-md-4 and you will see the results.
.col-md-4{ margin: 20px auto; } /* Or use my-* classes */

In stackblitz, there's no button to add a new product. Either you are adding the new product manually or the code is missed from the solution.
If adding manually, possibly you are adding it as a new row instead of another column. Since you are using bootstrap layout, your code divides the screen area in 12 parts, and each image is using 4 parts (sm-12, sm-4 respectively). Now when you add another product, that creates a new row since there's no space remaining in the current row.
To fix this out, rather than giving part by part allocation, give a fixed size to each product card, and then let the whole scroll horizontally.
Or, create another sm-12 row (3rd carousal) and add elements to it. You will be required to create a component hosting 3 products and each left/right button will cycle in the main carousal. Any product addition will go in the empty component and once filled, will create another instance to host the product.
--- pseudo code below, customize with actual values ----
#Component( {} }
export class ProductsContainerComponent {
products: Product[]
// template shows 3 products
}
#Component()
export class ProductCarousalComponent {
carousal: ProductsContainerComponent[]
btnPrevious, btnNext: Button => Each set the current pointer to a given container in list, which gets displayed
addNewProduct() {
ProductsContainerComponent container;
carousal.each(prod => if (prod.products.length < 3) { container = prod; break; } );
if (container == null)
{ container = new ProductsContainerComponent(); carousal.push (container); }
// construct your new product here (url, images, text etc)
container.products.push (new Product() );
}
