css - Implementing Unobtrusive Javascript -

i'm reworking old website , focusing on making javascript/jquery unobtrusive possible. i'm looking advice on 1 part of project: uj requires that, if javascript turned off in browser, site content still available user. 1 part of site has big list of items. each item in list has it's own description, uses css display:none hide default. clicking on item toggles visibility of description using jquery .toggle():, person unable utilize javascript (for whatever reason) never see it. if utilize javascript/jquery rather css hide descriptions, momentarily visible when page loads, want avoid. what's best solution?

basically can insert class "no-js" in html element, so

<html class="no-js" lang="en">

and if javascript enabled on client remove class (using modernizr or simpler code snippet like

<head> <script> (function(d) { d.classname = d.classname.replace(/(^|\b)no-js(\b|$)/, 'js'); }(document.documentelement)); </script> ... </head>

in way can avoid fouc (flash of unstyled content) using .no-js , .js class in css rules so:

.yourlistitems { display: block; } .js .yourlistitems { display: none; }

this approach used h5bp note don't need prepend .no-js class each rule: thinking in terms of "progressive enhancement" , "unobtrusive javascript" code , style first page works without javascript, add together functionality (and style specificity, prepending .js class)

javascript css unobtrusive

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...
