XMLHttpRequest Global Callbacks

A javascript library that allows for global XMLHTTPRequest callbacks

Why do you need this library?

Assume you would like to globally log onerror events in XMLHTTPRequests. It's easier to have one global callback that does this, then setting onerror on every request.

How to use this library

Just download xmlhttprequest-global-callbacks.min.js and include it in your html page.

<script type="text/javascript" src="xmlhttprequest-length-computable.min.js"></script>

Now you can register global callbacks for all XMLHTTPRequests using window.xmlHTTPRequestGlobalCallbacks

window.xmlHTTPRequestGlobalCallbacks = {
  "progress": function(event, request_method, request_url) {
    console.log(event, request_method, request_url);
  },
  "load": function(event, request_method, request_url) {
    console.log(event, request_method, request_url);
  },
  "error": function(event, request_method, request_url) {
    console.log(event, request_method, request_url);
  }
}

Any event name is possible.

Arguments passed to global callbacks

• event: The original event that was triggered
• request_method: The request method passed to XMLHTTPRequest.open()
• request_url: The url passed to XMLHTTPRequest.open()
