Autocomplete Example

Autocomplete Example

I have been creating posts with scripts to do small stuff, but on this post I would like to show/teach you how to implement the jQuery UI Autocomplete Widget. I have to remark that for the style of the application I am using Bootstrap, so the most important thing is the html code of the form and the Javascript code. This is the Part 1 of the tutorial.

Ajax usage to search a Record with PHP, MySQL and jQuery

I have created a few post about how to Search, Update and Delete data from a MySQL Database with PHP and PDO. Those tutorials are quite simple (but not dynamically enough, they don't use Ajax), but they are very important to catch the flow of this tutorial if you have never worked with this technologies. The tutorials are in Spanish so if you really need them in English I will be glad to translate them.

Something that I would like to remark is that you can get the scripts at the end of the tutorial.

In order to create a nice look and feel to the page I have implemented the framework Boostrap, but if you don't want to focus on the look and feel you only have to focus on the Form, the event to Fire the Ajax request and the server to process your request.

The next flow chart will show the path that we are going to cover to complete our Ajax search:

Antes de hablar de Ajax de jQuery voy a dar un antecedente de lo que es Ajax, porque si no sabemos de dónde viene no podemos comprender su uso. Una vez que entendamos como funciona Ajax, mostrare su uso a través de la librería jQuery, el cual es nuestro objetivo.
