Library for using DOM elements as well as Ajax requests

### `Rx.DOM.getJSON(url)`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS-DOM/blob/master/src/ajax/ajax.js "View in source")

Creates an observable sequence from JSON from an Ajax request.  This is just a shortcut to the [`Rx.DOM.ajax`](ajax.md) method with the GET method and parsing the `responseText` as JSON.

#### Arguments
1. `url` *(String)*: A string of the URL to make the Ajax call.

#### Returns
*(Observable)*: The observable sequence which contains the parsed JSON.

#### Example
```js
Rx.getJSON('/products')
  .subscribe(
    function (data) {
      // Log data length
      console.log(data.length);
    },
    function (err) {
      // Log the error
    }
  );
```
