3,489,035 | 3,489,036 | Is a JavaScript object automaticaly created for every HTML id? | <p>I'm giving a JavaScript course, and one of my students came up with a weird syntax that works but I don't understand why. I understand what it does, but would like to know if it is part of the JavaScript standard to react this way, or if it's a Firefox "glitch".
The question was simply to have a paragraph turn green or red depending if the mouse is over another paragraph. His answer was:</p>
<pre><code> <p id ="p1">a text</p>
<p onmouseover = "p1.style.color = 'red';"
onmouseout = "p1.style.color = 'green';">another text</p>
</code></pre>
<p>What I find strange is the "p1.style" part. What is p1? I understand that it is the <code><p id="p1"></code>. But does JavaScript automatically create an object for every ID?</p>

617,599 | 617,600 | Content Provider multiple app flexibility | <p>I've been training myself up in Android development. I have an idea for a series of apps that all relate to the same basic data store which stores similar/related hobby data. I suppose in my mind access to this data should be similar to how many apps make use contacts. So I started reading up on content providers but from what I can see they don't actually provide the flexibility I require.</p>
<p>What I want is to create say 4 or 5 hobby related apps that record similar and related data however a customer might decide they only need a specific one to start with. Later they might decide that one or more of the other apps might also be useful. </p>
<p>The data the apps store is very similar, the core data is the same. So the obvious choice is a content provider. However I can't see the providers offer the flexibility I require. Firstly how does the 2nd app purchased figure out that a content provider is already available and if so not install its own (this seems to be hardwired in the manifest and there is no programatic control). Secondly how would an app realise there is no content provider and install one (related to point one). Thirdly a new app installed might have a more up to date provider or an older provider!</p>
<p>So I don't think the providers offer what I need. I also notice that the databases are sandboxed and providers seem to be the only method for apps to share persisted data, or is there something I'm missing. It actually makes me wonder how for none default installed content providers how useful providers are!</p>
<p>I suppose an alternative method would be for a customer to purchase and app and then later ad on extra functionality but I'm not sure if this is possible and if so where the information is.</p>
<p>Any help would be appreciated.</p>

2,604,437 | 2,604,438 | Why is my string to string comparison failing? | <p>Ok so I have an Android app where I want to check to see if an app name that is installed matches a string passed to the function containing this code. The code and example is below:</p>
<pre><code>private Boolean checkInstalledApp(String appName){
PackageManager pm = this.getPackageManager();
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> list = pm.queryIntentActivities(mainIntent, 0);
Boolean isInstalled = false;
for(ResolveInfo info: list) {
if (info.activityInfo.applicationInfo.loadLabel( pm ).toString()==appName){
isInstalled = true;
break;
}
}
return isInstalled;
}
</code></pre>
<p>Assuming you called checkInstalledApp('SetCPU'); and the app name on the phone is called the same thing it should return true. However, it never does. I logged the results and it should match up but it does not. Can anyone please enlighten me as to why this doesn't work?</p>

3,123,894 | 3,123,895 | A Java bounds-checking optimization example | <p>I have read that some of the JVMs out there can optimize code execution by removing bounds checking. What I am trying to figure out is what coding technique will work better.</p>

<p>Is <strong>example2</strong> the better code practice? It would seem so, but in some algorithms inside a loop the index being out of bounds is a normal condition. So you don't want to be generating tons of Exception objects inside that loop.</p>
<pre><code>public void example1(int [] source, int index) {
if (index >= 0 && index < source.length)

<p>Basically I need to select the last table cell from each table row where the checkbox is marked, in this case the table cells containing "1.3" and "2.3" (not "3.3").

789,050 | 789,051 | 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>

<p>I have it parsing out the external ip's just fine. But, thinking like a ninja, I thought how cool would it be to handle dupes? The idea or thought process was that I can check the file that the ips are being written to against the current line for a match, and if there is a match, don't write. But this produces many more times the dupes than before :) I could probably use something else, but I'm liking python and it makes me look busy. </p>
<p>Thanks for any insider info.</p>

<pre><code>$project = new ReflectionClass( $instance_of_object );
$property = $project->getProperty( '_products' );
$property->setAccessible( true );
$products = $property->getValue( $project );

<p>I am trying to make sure a property is set correctly in my unit tests...</p>
