-======AJAX Generation======
-AJAX is the standard for Asynchronous Javascript and allows dynamic variables to be loaded into a page.  In WattmonOS, the home page uses AJAX to update its parameters once per second.
-Various packages may insert hooks that generate content in the AJAX output.   All parameters in the AJAX page are [[http://www.json.org|JSON]]-encoded.
-==== Generating AJAX ====
-In order to send parameters to the home page, your script should output one or more lines of valid JSON data, with a key and value in the format:
-<code json>
-"numeric_key":1,
-"string_key":"my string",
-"array_key":[1,5,6],
-"object_key":{"name":"Joe","age:21"},
-"array_object_key":[
-  {"name":"Joe","age:21"},
-  {"name":"Jane","age:32"}
-],
-</code>
-End each parameter with a comma (,).
-==== Generating AJAX in Blockly ====
-Below is an example script that will increment a global variable 'cnt' and send it to the AJAX output.
-{{:uphp:home_ajax.png|}}
-Example output of this:
-<code json>
-"cnt":334,
-</cod>
