jQuery.ajaxRetry

This plugin allows you to easily retry a failed ajax request while still allowing you to add callbacks via any of the normal options or deferreds. jQuery.ajaxRetry is supported on all version of jQuery from 1.5 - latest.

Usage

• Boolean If you set this to true, your request will be retried until it successfully completes. Be careful you don't DOS yourself here.

$.ajax({
      shouldRetry: true
});

• Number You can provide a simple number and the request will be retried that many times.

$.ajax({
      // Retry this request up to 2 times
      shouldRetry: 2
});

• Function Passing a function is the most flexible and powerful way to handle your retries. A retry will occur if your function returns true, or if it returns a promise that resolves to true.

$.ajax({
      shouldRetry: function( jqXHR, retryCount, requestMethod ) {
          // Retry only if the request method is POST and we have not retried this request yet.
          return requestMethod === "POST" && retryCount === 0;
      }
});

  $.ajax({
    shouldRetry: function() {
        // Always retry this request with a delay of 250ms between retries
        return $.Deferred(function(dfr) {
            setTimeout(function() {
                dfr.resolve(true);
            }, 250);
        }).promise();
    }
  });
