- *
- * 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); },

- *
- * 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); }
- * );

- *
- * 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); }
- * );
