javascript - Word counter function not working with barcode scanner -

$("#itemids").keypress(function(){ var value = $(this).val().replace(" ", ""); var words = value.split(","); $("#counter").html(words.length); });

this function works keyboard. when utilize barcode scanner, (i'm focusing cursor on textarea , starts scan barcode textarea delimiters comma.) doesn't work @ all.

i think must other keypress(function() . because bc scanner enters words programmatically. how work both situations: keyboard , bc scanner?

it looks solution use polling, not events.

function update(){ var value = $("#itemids").val().replace(" ", ""); var words = value.split(","); $("#counter").html(words.length); } setinterval(update, 10); // poll every 10ms

javascript jquery function counter

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
