Building a Site Search Functionality using jQuery
Welcome to this tutorial on building a site search functionality using jQuery. This tutorial is targeted towards web developers and software engineers who are learning how to use jQuery for things like autocomplete search on their web projects. By the end of this tutorial, you will have the skills necessary to build your own custom site search functionality.
Prerequisites
Before we get started, there are a few prerequisites you will need:
- A basic understanding of HTML, CSS, and jQuery
- A text editor such as Sublime Text or Visual Studio Code
- A web browser such as Chrome or Firefox
Planning the Search Structure
Before we start coding, let's plan out the structure of our search functionality. We will be creating a search functionality with an input field and a search results area.
<div class="search-container">
<input type="text" id="search-input" placeholder="Search...">
<ul id="search-results"></ul>
</div>
Search HTML and CSS Setup
Now that we have our structure planned out, let's create the HTML and CSS to style our search functionality.
.search-container {
position: relative;
display: inline-block;
width: 100%;
}
#search-input {
padding: 12px 24px;
width: 100%;
font-size: 16px;
border-radius: 25px;
border: 1px solid #ddd;
}
#search-results {
position: absolute;
top: 100%;
left: 0;
width: 100%;
z-index: 1;
list-style: none;
padding: 0;
margin: 0;
border: 1px solid #ddd;
background-color: #fff;
overflow-y: auto;
max-height: 300px;
}
#search-results li {
padding: 12px 24px;
cursor: pointer;
}
#search-results li:hover {
background-color: #f1f1f1;
}
Adding jQuery Functionality
Now that our HTML and CSS are set up, let's add some jQuery to make our search functionality work. We'll start by creating a function to retrieve the search results when the user types into the input field.
$(document).ready(function() {
$('#search-input').keyup(function() {
var searchValue = $(this).val();
if (searchValue.length >= 2) {
$.ajax({
url: 'search.php',
method: 'POST',
data: {search: searchValue},
success: function(response) {
$('#search-results').html(response);
}
});
}
});
});
In this code, we are listening for the keyup event on the #search-input element. When the user types into the input field, we retrieve the search value and check if it is at least 2 characters long. If it is, we make an AJAX request to a search.php file on our server, passing in the search value as data. When the AJAX request is successful, we replace the contents of the #search-results element with the response.
Customizing the Autocomplete Search
Now that our search functionality is working properly, we can customize it to fit our website's design. Let's add some styles to our search functionality to make it look more visually appealing.
.search-container {
position: relative;
display: inline-block;
width: 100%;
}
#search-input {
padding: 12px 24px;
width: 100%;
font-size: 16px;
border-radius: 25px;
border: 1px solid #ddd;
}
#search-results {
position: absolute;
top: 100%;
left: 0;
width: 100%;
z-index: 1;
list-style: none;
padding: 0;
margin: 0;
border: 1px solid #ddd;
background-color: #fff;
overflow-y: auto;
max-height: 300px;
}
#search-results li {
padding: 12px 24px;
cursor: pointer;
}
#search-results li:hover {
background-color: #f1f1f1;
}
Here, we've added some styles to our search-container, search-input, and search-results elements. We've also added styles to the individual search results within the search-results element.
