  • id vs class selection benchmark

    - by zaf
    Has anybody bench marked selecting elements with id's and class's from CSS and javascript? It would make sense that an element with an id is faster to select than if it had a class even if it was the only element with that class. Do I really need to be concerned?

  • Sanity Check: change event not firing first time using keyboard

    - by macca1
    I've done a good amount of research on this and found a bunch of reported problems and solutions but the general consensus seems that all change problems in IE6 were fixed in jQuery 1.4.2. I'm having an issue where a change event is not firing in jQuery 1.4.2, but it did fire successfully in jQuery 1.3.2. This is in IE6. I'm about to submit a bug for this, but for my sanity I wanted to post it here first to see if there's something dumb I'm missing. I don't understand why this is working this way... <HTML> <HEAD> <TITLE>jQuery 1.4.2 Problem </TITLE> <script src="jquery-1.4.2.min.js" type="text/javascript"></script> <script> $(document).ready( function() { $("#firstBox").change(function() { alert("CHANGE"); }); // ONLOAD of document autofocus into the first element... $("form").find(":input:visible:first").focus() }); </script> </HEAD> <BODY> <form> <select id="firstBox"> <option value="" selected="selected">--</option> <option value="1">One</option> <option value="2">Two</option> </select> <br><br> <input size="10" id="secondBox"> </form> </BODY> </HTML> Simple enough, right? Onload of the page, give the first element focus. Onchange of the first element, alert. If you use the mouse, it works as expected. The page loads, the focus is in the drop down, you change the option, you get the alert. The problem is if you use the keyboard. The page loads, the focus is in the drop down, you press the down arrow. The option changes. Tab off the field, no alert. Weird. To make it even weirder, if you tab back into the field and change it again (all using the keyboard), the change event DOES fire after tab out this time. Any ideas?

I can get all users by this query <?php $user_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->users;"); echo $user_count ?> But for the user count only with posts, i think i might need to join another table, does anyone have snippets ?

  • Regexp for handling recursive arguments

    - by Matt
    Hi all, I'm a regexp novice, so I'm wondering what the regexp for the following: function {function arg1, arg2}, arg3 I'm looking to be able to just select the top-level arguments: {function arg1, arg2} & arg3 Ideally the response would be using preg_match in PHP, but almost any regexp would work fine. Thanks! Matt

  • Control for ASP.NET that allows Global Address List (GAL) integration.

    - by jamone
    I know I can use System.DirectoryServices to roll my own GAL Name/email selector control and I've seen plenty of people explaining the basics of how to do that, but surly someone knows of one that I can download from somewhere. It just seems like a waste to have to remake it when so many people need it. Something remotely similar to Outlooks GAL Select Names dialog. It could be simpler.

  • c# - SQL - speed up code to DB

    - by user228058
    I have a page with 26 sections - one for each letter of the alphabet. I'm retrieving a list of manufacturers from the database, and for each one, creating a link - using a different field in the Database. So currently, I leave the connection open, then do a new SELECT by each letter, WHERE the Name LIKE that letter. It's very slow, though. What's a better way to do this? TIA

  • Stubhub like map in HTML5?

    - by Switz
    I have an image of a floor plan. Best way to think if it is a hotel floor plan. (Similar to how stubhub does their ticket maps) I want the user to select rooms. Instead of slicing each room in Photoshop, is there a way to split up the image in HTML5 canvas or Javascript. Would like to avoid flash. Thanks for the responses! example: http://adamsaewitz.com/housing/housing.html (top left rooms, hover)
