Background image css animate() within setInterval() function call in JQuery -

i have noticed behaviour can't explain. i'm sure must limited knowledge of jquery/javascript.

when run next code on webpage, works expected - background image rotates:

//background image rotator var imgarr = new array('/images/1.jpg', '/images/2.jpg', '/images/3.jpg'); var preloadarr = new array(); var i; /* preload images */ (i = 0; < imgarr.length; i++) { preloadarr[i] = new image(); preloadarr[i].src = imgarr[i]; } var currimg = 1; var intid = setinterval(changeimg, 5000); function changeimg() { $('#homediv').css({ 'background': 'url(' + preloadarr[currimg++ % preloadarr.length].src + ')' }); }

however, if replace .css() function .animate(), in next code, currimg++ seems increment 2 , wrong image loads.

//background image rotator var imgarr = new array('/images/1.jpg', '/images/2.jpg', '/images/3.jpg'); var preloadarr = new array(); var i; /* preload images */ (i = 0; < imgarr.length; i++) { preloadarr[i] = new image(); preloadarr[i].src = imgarr[i]; } var currimg = 1; var intid = setinterval(changeimg, 5000); function changeimg() { $('#homediv').animate({ 'background': 'url(' + preloadarr[currimg++ % preloadarr.length].src + ')' }, 1000); }

is due setinterval process getting 'out of sync' due animate() function taking 1000ms?

thanks

alex

remove setinterval , write code

function changeimg() { $('#homediv').delay(5000).animate({ 'background': 'url(' + preloadarr[currimg++ % preloadarr.length].src + ')' }, 1000, function() { changeimg();} ); }

like said, setinterval gets asynchronous animate function. here chaneimg runs 1 time again callback function everytime it's done executing itself.

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...
