Wanna try the vanilla JavaScript version?
(function() {
var $sketcher = $('#drawing-canvas').sketchable();
var $outputEl = $('#drawing-data');
$('#tosvg').click(function(evt) {
evt.preventDefault();
$sketcher.sketchable('svg.create', function(contents) {
$outputEl.text(contents);
});
});
$('a#clear').click(function(evt) {
evt.preventDefault();
$sketcher.sketchable('clear');
$outputEl.empty();
});
})();
