Small Ajax JavaScript library

I'm programming a library that needs a function to load URLs asynchronously. I'd need the precise same functionality of $.get, except I don't want to have jQuery as a dependency of my library for just one function. What is a self-contained snippet that allows for this?

I've tried several things but most of them are broken somewhere. For example, the most elaborate I could find would get the error Origin <url> is not allowed by Access-Control-Allow-Origin on Chrome.

  • Yes, I am. I'm reading on that link, it says I need to have a local proxy and I have no idea on how I'd have to do that. Commented Dec 15, 2012 at 3:05

You need to use a basic Ajax call. Look at any tutorial on the XMLHttpRequest object. BUT the problem you have is you are trying to make a cross domain call. That is not possible because of the same origin policy.

In modern day browsers you can make a CORS request, but the server you are requesting has to support it.

Other option is running a local proxy [means you have to have a serverside language application]

The third option is to use a service like yahoo pipes with a jsonp call.
