Do something if an image is not loaded (jquery) -

i'm looking fade in background image when visitor arrives @ site not when they've got image in cache. along lines of this:

check if background image in cache. if show it. if isn't hide , when loads, fade in.

using jquery can hide , fade in when loads:

$("#bkg img").hide(); $('#bkg img').load(function() { $(this).fadein(); });

but how create conditional happens if image isn't cached?

everything i've found on forums triggers when image finishes loading. how can trigger because isn't loaded?

thanks help, lernz

@sima based on code that other thread i've made far next - doesn't seem having effect. if can see i'm going wrong that'd great:

var storage = window.localstorage; if (!storage.cachedelements) { storage.cachedelements = ""; } function logcache(source) { if (storage.cachedelements.indexof(source, 0) < 0) { if (storage.cachedelements != "") storage.cachedelements += ";"; storage.cachedelements += source; } } function cached(source) { homecoming (storage.cachedelements.indexof(source, 0) >= 0); } var plimages; //on dom ready $(document).ready(function() { plimages = $("#fundo-1 img"); //log cached images plimages.bind('load', function() { logcache($(this).attr("src")); }); //display cached images plimages.each(function() { var source = $(this).attr("src") if (!cached(source)) { $(this).hide().fadein(); } }); });

you can try:

if(!$('#bkg img')[0].complete) { $('#bkg img').hide().load(function () { $(this).fadein(); }); }

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...
