Answer 1

Your JavaScript runs on the client (in the browser). Your MySQL database exists on a server.

In short, the client-side JavaScript cannot establish a direct connection to MySQL. You need to make an AJAX request to the server which runs a script that interacts with MySQL. The script can be written in any language that has a MySQL library.

Here's an example where an AJAX request is made, which calls a PHP script on the server, which, in turn, grabs data from a MySQL database and returns results back to the client:

Answer 2

Is it possible to insert data into MySQL database without using JQuery?

Yes.
That said, jQuery helps you a lot dealing with Ajax (and cross-browser compatibility), so I would still consider it.

Can anyone send any link of simple example or tutorial to deal with the issue?

Any Ajax tutorial will do it (e.g. https://developer.mozilla.org/en/AJAX). You just have to learn how to send data to the server side (as POST or GET request). Then it is just PHP and MySQL.

Answer 3

You can connect to a MySQL database via JavaScript using ActivexObject. Example:

var conn = new ActiveXObject("ADODB.Connection");
var connStr = "Provider=SQLOLEDB;Server=mysite;Database=Northwind;User Id=MyId;Password=123aBc";
conn.open(connStr); 

Answer 4

You could send a GET request to a server script with AJAX:
