here is the JS code with some comments

$(document).ready(function(){ // this function executes when page is loaded
  $('#yourInput').change(function(){ // implements a handler on the onchange event - function will execute whenever value changes
    $.get(yourURL + '?' + $(this).val(), // sends an AJAX get to your server at the specified URL
       function(html){ // this function will execute when AJAX request receives a response from the server - html contains this response
        $('#divID').html(html); // replaces the html contents of the element having 'divID' as ID by the html received from AJAX response
    }
  })
});

developing with jQuery and AJAX is fun!


>I will have to think and understand your approach. I know it is a simple example but I am not familiar with "change" and ".get" syntax. Usually in my ASP.NET program, to get any data, I have to call a method of a Data Access class and pass a SQL Select to it. So I will need to see how it can be applied to your suggestion.

>>>Hi,

>>>I am thinking of adding the following simple feature to one of the pages of ASP.NET application.

>>>But if I want to do it without reposting the page (as often you see today in the internet pages) should I use jQuery.ajax? I am just about to start viewing some courses on this topic on Pluralsight but would like to know that I am on the correct path.

>>>TIA for any suggestions.
