  • Handling "other" option in dropdown select with free text input field

    - by ted776
    Hi, I'm trying to figure out the best way to handle a dropdown list where one of the options "other" shows a hidden text field (via jQuery), where the user can then enter text. Should both the dropdown and the input field be given the same "name" attribute, then server side code runs a check on the values of each in order to know what one is the active value - e.g if the value of the select box is "other", then check the value of the text input field - if this isn't the default value ("enter text"), then it's ok to use this value and save it to the database. Is this a messy approach to this problem?

  • What are the hot languages of 2009?

    - by geowa4
    It is well-accepted that we should all learn something new every six months. But what should top the list for 2009? What new things should we learn this year that appear to have real staying power? (Answers do not have to be limited to languages.)

  • How much benefit do you get from working with other developers?

    - by SnOrfus
    For whatever reason I've only ever worked solo. The job that I have now, I was under the impression that I was being hired to work underneath a senior developer and that I'd be able to learn from them/their code. This was actually one of the conditions that I had when I accepted the position (that and I was broke and needed the cash - so I would have likely taken it anyway). As it turns out, the intention of management was for me to replace that senior developer because they were contracted and relatively expensive. The question I have is, though I've learned a lot in the 2 short years I've been here, am I potentially seriously stunting my learning/progress working solo instead of working at a company with other developers?

  • How to determine which enemy is hit and destroy it alone

    - by Jon Ferriter
    http://jsfiddle.net/5DB6K/ I have this game being made where you shoot enemies from the sides of the screen. I've got the bullets moving and being removed when they reach the end of the screen (if they didn't hit any enemy) and removing the enemy when they collide with it. //------------collision----------------// if(shot === true){ bulletY = $('.bullet').position().top + 2; bulletX = $('.bullet').position().left + 2; $('.enemy').each(function(){ if($('.enemy').hasClass('smallEnemy')){ enemyY = $(this).position().top + 7; enemyX = $(this).position().left + 7; if(Math.abs(bulletY - enemyY) <= 9 && Math.abs(bulletX - enemyX) <=9){ $(this).remove(); score = score + 40; bulletDestroy(); } } }); } However, the bullet destroys every enemy if the collision check is right which isn't what I want. I want to check if the enemy has the class of either smallEnemy, medEnemy, or lrgEnemy and then do the collision check which is what I thought I had but it doesn't seem to work. Also, the game starts to lag the more and more time goes on. Would anyone know the reason for that?

The question is why? What led you to make this change? EDIT: Also, what framework (if any) did you change to?

  • HTML5, CSS3 columns

    - by DrGizmondo
    Hay all im building a news aggregator with SimplePie, the SP elements are working fine but I would like to have the feeds that it pulls in displayed in columns across the page using HTML5 and CSS3. I have managed to implement it so that the columns are formed and display the feeds, but at the moment the stories are being ordered one on to of the other from left to right with the newest being displayed top left, the second newest bellow the first in column one and so on. What I would like is for the stories to be displayed from left to right across the column so that the newest is at the top of the first column, the second newest at the top of the second column, the third newest in the third column and so on. The code that Im using at the moment is as follows: <div id="page-wrap"> <?php if ($feed->error): ?> <p><?php echo $feed->error; ?></p> <?php endif; ?> <?php foreach ($feed->get_items() as $item): ?> <div class="chunk"> <h4 style="background:url(<?php $feed = $item->get_feed(); echo $feed->get_favicon(); ?>) no-repeat; text-indent: 25px; margin: 0 0 10px;"><a href="<?php echo $item->get_permalink(); ?>"><?php echo $item->get_title(); ?></a></h4> <p class="footnote">Source: <a href="<?php $feed = $item->get_feed(); echo $feed->get_permalink(); ?>"><?php $feed = $item->get_feed(); echo $feed->get_title(); ?></a> | <?php echo $item->get_date('j M Y | g:i a T'); ?></p> </div> <?php endforeach; ?> And this CSS: #page-wrap { width: 100%; margin: 25px auto; height:400px; text-align: justify; -moz-column-count: 3; -moz-column-gap: 1.5em; -moz-column-rule: 1px solid #c4c8cc; -webkit-column-count: 3; -webkit-column-gap: 1.5em; -webkit-column-rule: 1px solid #c4c8cc; } If anyone could help me out with this that would be great.

  • Include a repetitive chunk of html with PHP?

    - by user146780
    I basically have a div on my Web Site that always has the same stuff. However, this div is not present on all pages which is why I won't use the dynamic web template. I was wondering if it was possible for PHP to get the code from a document on the server and put in into the div? Ex: div id="section... then my text file contains (p) hello (p) basically I want PHP to put it into the div when the user sees it. If theres a smarter way of acheiving this I'd be open to it aswell. Thanks

  • As a Web Developer, how complicated is your average job compared to this?

    - by Daniel S
    I'm 16 years old, and I've recently started to do freelance jobs. I've been playing with PHP since I was 12 and think that I can code reasonably well. So far, I've created a library for fetching info from LinkedIn profiles and some WordPress plugins. However, right now this client wants me to convert an HTML template into a WordPress theme for use as a website. I feel this is a tad easy. As professional web programmers, are most assignments harder than this?

  • How do I pick the most beneficial combination of items from a set of items?

    - by Chu
    I'm designing a piece of a game where the AI needs to determine which combination of armor will give the best overall stat bonus to the character. Each character will have about 10 stats, of which only 3-4 are important, and of those important ones, a few will be more important than the others. Armor will also give a boost to 1 or all stats. For example, a shirt might give +4 to the character's int and +2 stamina while at the same time, a pair of pants may have +7 strength and nothing else. So let's say that a character has a healthy choice of armor to use (5 pairs of pants, 5 pairs of gloves, etc.) We've designated that Int and Perception are the most important stats for this character. How could I write an algorithm that would determine which combination of armor and items would result in the highest of any given stat (say in this example Int and Perception)?
