/**
|
||
* This plugin requires jquery.json.js to be available, or at least the methods $.toJSON and
|
||
* $.parseJSON.
|
||
*
|
||
* The plan is to make use of websockets if they are available, but work just as well with only
|
||
* http if not.
|
||
*
|
||
* Usage example:
|
||
*
|
||
* var foo = new $.JsonRpcClient({ ajaxUrl: '/backend/jsonrpc' });
|
||
* foo.call(
|
||
* 'bar', [ 'A parameter', 'B parameter' ],
|
||
* function(result) { alert('Foo bar answered: ' + result.my_answer); },
|
||
* function(error) { console.log('There was an error', error); }
|
||
* );
|
||
*
|
||
* More examples are available in README.md
