In this tutorial we will create a Real Time Search using JavaScript. This code will search a specific data every time the user enter some characters in the textbox. The code use onclick() function to call a specific function that automatically filter the data when entered, by using a for() loop and adding a if statement with an argument indexOf() in order to filter the index position of an array. Feel free to modify and apply it in your system, this is a user-friendly kind of program
We will be using JavaScript as a server-side scripting language because It gives a greater control of your web page and extend its capability in a modern way approach. It is written in HTML or as an external sourcing to add some necessary features in your website.
Getting started:
First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.
The Main Interface
This code contains the interface of the application. To create this just write these block of code inside the text editor and save it as index.html.
Creating the Script
This code contains the script of the application. This code will search a data when entered. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder.
There you have it we successfully created a Real Time Search using JavaScript. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
