Ajaxito

Ajaxito is a pretty small ajax class, based on moo.ajax and microajax, it only weights 1kb uncompressed, to use it, just call it like:

new Ajaxito( url, callback, post );

  • url: The url to get the data
  • callback: The function to execute once the ajax request has been done
  • post:This last parameter is optional, here you can include the post body

Here is an very basic example on how to use it

  1.  
  2. new Ajaxito (‘ajax.php’, ‘alertResponse’, ‘var1=3&var2=test’);
  3. function alertResponse(request){
  4.         alert(request.responseText);
  5. }
