jQuery querying the database

Question

The thing is that there are number of items in the HTML select list. I want to click on any of the items, then query the database on the id of that item, retrieve the value and then display that in the textbox. How would I query the database?

I would really appreciate that if someone provides a code sample for querying the database.

Answer 1

Have jquery fire an ajax call to your server. Your server is what will actually query the database.

Answer 2

Something like

$.get('/ajaxquery/yourselectvalue', function(data) {
  $('#yourTextBox').val(data);
});
