Hi E's, my knowlgment in Ajax is very poor, usually I use HTML and php for made my websites.
Now I need to resolve a problem with Ajax, and maybe this step was my beginning in Ajax.
In snippet code I have a form, where I can put a number, and that number have a title correspondent in my database. If I write 1000 appear one title, if I write 1001 appear another title and so on....
That is what I want do in Ajax, the script have to read the database correspodent for that number, and present data in "<div id="config_titulos">HERE PUT THE INFORMATION COME FROM DATABASE/AJAX</div>".
The db query you see in the beginning of the code, is usually the code I use to get data from db, in this specific case "tutorial" is where located the number, and "title" is where is locates the data from title correspondent for each number.

How I do in Ajax the presentation of title for different numbers I put in the form?

The best regards, JC
