We won't be using any fancy frameworks but rather use the regular DOM API.
When we send, the message is processed and then written into the text file as a new line.This is just to let the PHP file know what kind of thing we need done.As such, the first thing we'll do is snag that value and set up a switch statement that covers each possible function.So we'll need to call that update function on a regular basis, and we'll use Java Script's set Interval() function for that: Download Files Note: Remember this is PHP powered, so you can't just download the files and open them on your local machine and have it work, unless you are running a local PHP server.Also remember to change the file permissions of the file to be writable by the server when uploading to your own test location.We're going to be building a real-time Java Script chat room similar to Twitch.tv's chat using Java Script and Scaledrone realtime messaging service.
The app is going to be using Websockets on modern browsers and fallback technologies on older ones.In this tutorial we are going to build a little chat program that is really easy to get up and running on any server running PHP. It's just a fun demo and totally workable in a number of situations.No database is required - as the chat will store itself in a simple text file. If you want to take this and run with it and make it more full featured, be our guest! Even what you are looking at above is 50% unrelated to the specific functionality of this tutorial. The double-divs thing going on with the chat-wrap and chat-area is just to pull off the totally unnecessary (but cool) double border effect in the chat area.get State Of Chat asks the server basically how many lines the current text file is, so it has something to compare against and know when lines are "new" or not. And those functions look like: All three of these functions make use of j Query's AJAX abilities, and do their communicating with a PHP file called process.php, which of course we'll need to build!Part of the data that gets passed with the AJAX calls is an (arbitrary) value named "function".update Chat will ask the server if there are new lines in the text file.
