javascript - Tornado doesn't send Ajax response to client -

upon form submit tornado server checks , sends response client, should appear in current page alert.

instead blank html page rendered json response, not alert on current page form submitted.

on submit form sent via post /dh (datahandler)

this jquery:

$.post("/dh",function(data,status){ alert("data: " + info + "\nstatus: " + status); },"json");

the tornado code:

class datahandler(basehandler): def post(self): # checks done form info received dupinfo={ 'tel' : duptel, 'name' : dupname } self.write(json.dumps(dupinfo, default=json_util.default)) self.finish()

so how can homecoming json current page?

after "alert" statement, add together return false;. disables browser's default handling of post event. browser's default behavior navigate new url, , want prevent that.
