This script is an eyeopener, the holygrail of understanding for anyone wishing to take that next step of a website that auto updates every bit of information without reloading the wholepage for new information, it will refresh live if any new information comes along , it can read from a database live to the screen, as soon as the information arrives, usually with a timer function also running.
BUILD IT
To begin an auto update feature on your website, you will need to string together a few jquery events and functions.
- First you would create a button for your trigger, then give it an id.
- Then create a jquery timer function that runs every 10 seconds, with a function of click() using the button you just created.
- This will run the code to check the file change or database call, and get the data, it can check the data and run a function, or send an email, or change a css style to increase the size of a bar, it could probably interact with many other xml weather sites, and retrieve scores and other live data, if you know the url, or have a source thats xml or text, maybe a database that you have access to. Where’ s your data, that’ s the first thing you have to find out!
- The next part it again very much needed – What to do with this data? Do I check it, capitalise it, hide a div, add a style, send an email, or update another database, etc.
The jquery would wait for a click function of that id and if so read the file and it will update.
