I know enough jQuery/JavaScript to be dangerous. I have a JSON array that I’m interacting with using two different elements (a calendar and a table, to be precise). Is there an event handler (or any other way) I could bind to so that the table would refresh when the JSON changes?
Basic programming, parse the json (=string) into a javascript object or array. (you probably have already done that.) Use an implementation of the observer patern.
I suggest taking a good look at @Adam Merrifield ‘s interesting links.
Most of the time using getters and setter where you can fire a custom event (or call a callback method) inside a setter is the key in this.
KnockoutJS is a good framework to help you do such binding. It also uses the observable – observer/subscriber pattern.
using timers is not a really good idea.. little to much overhead. (doing stuff also when nothing gets changed. And you will always hop x ms behind (depending on the polling frequency).
