self.IPAD = YES;

<p>My idea is to include this in <code>myConstants.h</code>.</p>
<p>But how can I do that if myConstants.h is just a plain file where every line is a <code>#define</code> entry without any method?</p>
<p>My idea is to have <code>DEVICE</code> and <code>IPAD</code> variables as globals for the entire app and make them available to any class by just <code>#import "myConstants.h"</code>.</p>

1,951,811 | 1,951,812 | Difference between undefined and not being defined in Javascript | <p>See <a href="http://jsfiddle.net/FDhQF/1/" rel="nofollow">http://jsfiddle.net/FDhQF/1/</a> for a trivial example.</p>
<p>What's the difference between something being undefined and something not being defined in Javascript? For instance, trying to access a property for an object (effectively, trying to access a variable) that isn't defined will return <code>undefined</code>. But you can also set something <code>= undefined</code>. When you do that, trying to access it still return undefined, but the pointer is still there. An example, as above, is how iterating over an object still goes over the property that you've (re)declared as undefined. It seems like there are two different sorts of undefined. Can anyone shed some light on the situation?</p>

3,628,940 | 3,628,941 | Is document.location.protocol ever invalid? | <p>I want to construct URLs with the same scheme (presumably, "http:" or "https:") as the page that loaded the currently-running JavaScript. Modern browsers support simply omitting the scheme (for example, <code>src="//example.com/test.js"</code>), but this isn't fully cross-browser compatible. (I've read that IE 6 is the only browser that doesn't support it, but I still need compatibility with that version.)</p>
<p>The cross-browser way to do this seems to be to check <code>document.location.protocol</code>. For example, Google Analytics uses:</p>
<pre><code>('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + ...
</code></pre>
<p>In Google's case, they wanted to use different domains depending on whether the request uses SSL, so that pattern makes sense. But I've seen others use the same pattern when only the scheme is changing:</p>
<pre><code>('https:' == document.location.protocol ? 'https:' : 'http:') + "//example.com"
</code></pre>
<p>(One example is in the "Final Wufoo Snippet" at <a href="http://css-tricks.com/thinking-async/" rel="nofollow">http://css-tricks.com/thinking-async/</a>.)</p>
<p>I'd prefer to use this simpler expression instead:</p>
<pre><code>document.location.protocol + "//example.com"

<p>Should I really be concerned about the possibility of <code>document.location.protocol</code> taking on some value other than "https:" or "http:" when my code is used on sites I don't control?</p>

3,710,508 | 3,710,509 | Forms with a variable number of fields | <p>I'm attempting to create a sort of marketplace. Each item on the market has a type (i.e. the item being sold), a value, a quantity, a seller name, and an id, and all of this information is stored in a MySQL database.</p>
<p>When the user views the market, all entries in the market are returned. In addition, an input text field appears at the end of each entry. The user can enter any number between leaving it blank (0) and the max quantity available.</p>
<p>My problem is that since each input field is the result of a while loop of unknown iterations, I can't simply hard code a name into each field. I've tried using a counter variable to keep track and make names, but it doesn't seem to be working. For example: <code>name='.$i++.'</code></p>
<p>On a related note, in order for the program to work, each field needs to send two values - the id (which I can use to look up the rest of the entry's values) and the quantity that the user wishes to purchase. I've been doing this with a hidden field before the input quantity field. I'm not sure if this is a good way of going about this, but I should note that there's no need as far as I can tell for the id to be kept secret.</p>
<p>Just so everything's clear, here's a basic UI mockup:
<a href="http://img850.imageshack.us/img850/2654/marketui.jpg" rel="nofollow">http://img850.imageshack.us/img850/2654/marketui.jpg</a></p>
<p>Note that the column starting with consists of user inputted values (i.e. the 100s are the values of user-inputted text fields). The hitch is that while there are 2 rows in this example, the actual number is not deterministic, and so I can't hard code names for each input field.</p>
