You can try it:
in view:
function update() {
var url = '{{=URL(f="update",args=request.args,vars=request.vars)}}';
var data = document.getElementById('drawcomment').toDataURL("image/png");
$.ajax({
url: url,
type: "GET",
data: {'data':data},
success: function (html) {
$('#results').html(html);
}
});
return false;
}
in controller:
def update():
return db().insert(data = request.vars.data)
