What do you mean by that? Javascript runs on the client, whereas the DB is on the server. Are you maybe asking : how can Javascript code call server-side code which in turn calls the DB? If so, then a library like jQuery or Prototype may be involved.

Do you mean to connect to database from JavaScript? If that's the case then yes, you can, but it's not recommended to do so (mostly for security issues). It is a bad practice so it would be better to choose a server side language to establish a connection to db.

Also I think there is a separate subforum for these questions (HTML, CSS and JavaScript).

I created one .js file.

In that I created an Ajax form and that Ajax form is having a checkbox which I want to check it when the value in the (Database)table in Y.

JavaScript can not connect directly to the server so you will need to make an Ajax call back to a serverside page that can check the database for you. Other option is to have the page spit out the information you need in a script block when the page is rendering and the script uses that information.

Or if you are using JSP on the server, simply have the JSP set the attributes as appropriate before the page even reaches the browser.

As pointed out, JavaScript in the browser cannot directly access the DB.
