There is no direct way. You have to use Ajax. :)

Solution 1

No, you cannot. You client-side script has no access to the database directly. The closest is via Ajax call, but it still has to go through a server-aide script like php which in turns handles the database operation.

Javascript is a client side language means it wont access the database.

So you need to use php or any server side language to access the database.

If you use ajax it will fetch data from db without refreshing the page.

If the data that you want to query is not a very huge data then you can try doing the below:

1) Create an asp file that will fetch the data and write it into an htmltable
2) Include that asp file in your parent file
3) Use document.getElementByID to query that htmltable for the data you want

Please do not try this for very huge data queries as this will make your page heavy. You can also use it for table like master entries - that do not change often
