Extend jQuery ajax function to retry requests and perform compensate action

retryAjax

I wanted a little wrapper function to retry ajax requests in the event of transient failures (particularly likely for mobile sites). This is my first stab at a little wrapper over jQuery's ajax function.

Options:

• retries: The number of times to retry requests (default is 3)
• backoff: Boolean option on whether to increase time between attempts (default false)
• backoffInterval: Starting interval between wait time for requests (default 1000),
• backOffFunc: Function to increase time between retries (default function multiples current backoffInterval value by 2 on each attempt)

Example usage:

$.ajaxWithRetries(
	{
		url: "badUrl.html",  
		error: function(){
	 		console.log('original error handler func');
		} 
	},
	{
		retries: 3,
		backoff: true
	}
);
