Auto Complete Using JQuery

Need sample Java Script for implementing auto complete of a text box using Ajax ( Using JQuery)

can you let me know the JQuery script files that need to be included and a simple page that works by calling a URL and displays the options while we enter text into a textbox.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you use jquery ui, it is well documented.  http://jqueryui.com/autocomplete/

I am not able to make the above code working even with a valid URL that fetches the data for suggestions. Not sure where the code is breaking. where can we put some alert boxes to debug this.

also , will the above code make the ajax call implicilty to the URL specified? is Angular JS better to implement the auto complete,.

Please post a link to your sample you are working with.  If you you are working locally, then create a sample page you can post. Otherwise we are just guessing.

I am running the same code you posted as is , except for the URL which is pointing to a web server on my local machine. Where can put the alert box in the code below to debug.

$( "#birds" ).autocomplete({
      source: "search.php",
      minLength: 2,
      select: function( event, ui ) {
        log( ui.item ?
          "Selected: " + ui.item.value + " aka " + ui.item.id :
          "Nothing selected, input was " + this.value );
      }
    });
