html - Get Iframe to fill to bottom of page -

this seems should simple question cannot seem find solution anywhere.

on website making have navigation bar @ top of page 43px in height , in effort not have edit each individual page create did set iframe below @ 100% width navigation buttons targeting source of iframe.

now run issue want iframe extend bottom of navigation bar bottom of page cannot tell iframed in if set height 100% set height of entire page , adds 2nd scrollbar compensate 43px @ bottom, how can fit iframe remaining space below nav bar ?

i have tried setting different % not work different res monitors. , need work cross browser (in ie, chrome, safari, , mozilla, preferably in opera that's not necessity).

sorry little wordy, can help?

pretty simple. need subtract height of navigation current viewport height , set iframe's height. utilize javascript method:

function resizeiframe() { var nnavigationheight = 43; // assuming 43px stated above var nviewheight = document.body.clientheight; var niframeheight = nviewheight - nnavigationheight; document.getelementbyid("youriframeid").style.height = niframeheight + "px"; }

you'll need set body , html 100% height work.

body, html { height: 100%; }

i should mention dubious way of achieving want do, it's solution true letter of question. i'd recommend using jquery rather vanilla javascript cross-browser headaches minimised (i've tested code in current installations of ie 7 & 8, ff, chrome, , safari without issue, mileage may vary). if decide go route, improve take advantage of first-class , simple ajax functionality using div , dispense iframe entirely.

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...
