alfaAjax

JavaScript ES3 replacement of jQuery.ajax()

I love jQuery!
$.Ajax() is great, but it was dropped from jquery.slim.js build. I need a basic functionality to handle JSON communication with server, so here it is. Please report any issues with it.

Syntax

alfaAjax.mode(url [,options] ,successCb [,errorsCb]);

url {String} - url to call
options {Object} - optoins, see below. (optional argument)
successCb {Function} - callback function returning response data
errorCb {Function} - callback function returning error data (optional argument, if not present, errors are logged to console)

Each method has two callbacks: sucessCb and errorCb. On timeout event is handled by errorCb

  alfaAjax.get( url, options, successCb, errorCb)
  
  alfaAjax.post( url, options, successCb, errorCb)

  alfaAjax.mode( url, options, successCb, errorCb) // mode is passed in options={mode:'PUT'}

above methods use XmlHttpRequest and default data type JSON
options and defaults:

var defaults = {
    mode: 'GET',
    type: 'json',
    timeout: 25000,
    contentType: 'application/json',
    data: null
}

---

  alfaAjax.jsonp( url, options, successCb, errorCb)

this method is using <script> tag and JSONP
options and defaults:

var defaults = {
    timeout: 25000
}

---

alfaAjax.page(url, options) // options={data: myDdataObject}

this is not an AJAX method, it passes data to server and gets a web page in response,
like <form method="POST" action="url"> On server side, the data arrives as JSON and has to be parsed: JSON.parse(req.body.data)
