3,281,693 | 3,281,694 | select content of div from certain offset | <p>I'd like to select all the contents of a division from a certain height, using the height as a sort of offset. I load data from a database, put it in a div, and then get the height of the div:</p>

<p>i get the height of the div:</p>
<pre><code>var heit=$(\"#gtheight\").height();

<p>I have a threshold of 470px. If the content returned gives the div a height of anything more than 470px, the surplus content should be extracted, and placed in another div. So if the content gives a height of 500px, content occupying the last 40px or so (i add a surplus to the difference for appearance reasons) should be taken and placed into another
div(500-470=30px, i add 10px to give 40px). I know i can't do this:</p>
<pre><code> divsaved.innerHTML=divloaded.innerHTML;//where divloaded is the variable relating
//to the data from the db.
</code></pre>
<p>because that'll just put all the html from div1 to div2. So is there a way to do this using javascript?</p>

3,912,714 | 3,912,715 | Non-urgent Android layout id attribute quirk | <p>I'm working on a couple of apps at the moment while I try to learn my way around the Android SDK. I had a bit of trouble recently with my layouts where I was defining, for example, an EditText element as such...</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:id="@+id/price_per_pack"
android:layout_width="100dip"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/price_per_pack"
android:layout_alignParentLeft="true"
android:textSize="12pt"
android:text="Price Per Pack"/>
</LinearLayout>
</code></pre>
<p>The application was compiling correctly, however when I attempted to start the activity which utilizes this layout nothing would happen. Through a process of elimination I identified the id attribute as the troublesome one and while playing about I discovered that changing </p>
<pre><code>android:id="@+id/price_per_pack"
</code></pre>
<p>to </p>
<pre><code>android:id="@+android:id/price_per_pack"
</code></pre>
<p>solved my problem and the application behaved as expected. My initial attempt at declaring the id attribute was based upon examples in the SDK documentation so I'm wondering if somebody could explain to me why I needed to make the above change to get it working?</p>
<p>I'm sure that it won't make any difference but I'm developing using the android-mode.el emacs plugin and have a completely up-to-date copy of the SDK.</p>
<p>Thanks in advance.</p>

3,771,148 | 3,771,149 | AppendTo, does it change the DOM? | <p>I have two list boxes and some JQuery function that does the following:</p>

<p>When I tried to google it, I only came across cookies and sessions, but I don't know how to use them, and was hoping there was a more simple way. I only started with PHP today.</p>
<p>On the following page I want the user to be able to switch background, text color, text decoration, etc. I got that to work as well, but I would love to find a way to save the previous choice, and add it to the next one.</p>
<p>So if someone picks a red background-color, it should not switch back to white when they pick another style, such as a black text color.</p>
<p>Is there a easy way (for starters like me) to fix this?</p>

1,388,511 | 1,388,512 | How do you walk through the directories using python? | <p>I have a folder called notes, naturally they will be categorized into folders, and within those folders there will also be sub-folders for sub categories.

list_of_files = {}
for element in os.listdir(path):
# if the element is an html file then..
if element[-5:] == ".html":
list_of_files[element] = path + "/" + element
else: # element is a folder therefore a category
category = os.path.join(path, element)
# go through the category dir
for element_2 in os.listdir(category):
dir_level_2 = os.path.join(path,element + "/" + element_2)
if element_2[-5:] == ".html":
print "- found file: " + element_2
# add the file to the list of files
list_of_files[element_2] = dir_level_2

else:
for element_4 in os.listdir(subcategory_path):

</code></pre>
<p>Note that this is still very much a work in progress. Its very ugly in my eyes...
What I am trying to achieve here is to go through all the folders and sub folders down and put all the file names in a dictionary called "list_of_files", the name as "key", and the full path as "value". The function doesn't quite work just yet, but was wondering how would one use the os.walk function to do a similar thing?</p>

4,651,541 | 4,651,542 | Android Java, bitmap from resources | <p>I have my images in my res/drawable folder, there's no problem about that.
The thing is, i'd like to be able to do something like this:</p>
<pre><code>Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.*img[contar]*);
</code></pre>
<p>In other words eclipse doesn't let me do this <code>img[contar]</code> it only accepts the specific name of the image file (example: crystalblue), and i'd like to lets say move from "crystalblue" to "crystalred" image and in my case i need a variable to do it.</p>
<p>Obs: I did declare img as string array.</p>
<p>Any solutions anyone?</p>

3,001,517 | 3,001,518 | Comparing Java Beans with BeanComparator | <p>I am trying to compare 2 beans of the same class and determine what part of the beans (if any) do not match. This may include beans with internally nested beans of another class, but for the most part the classes will be matching. Basically I want to derive the first class from the database and compare it with a new copy which will inevitably update the data in the database that is not already the same as whats currently in there.</p>
<p>So basically I will need to loop through each variable in the bean and compare it with bean 2. If it matches...move onto the next. If it does not match, return the index of the variable so I know what field to update in the database. </p>
<p>Is this something I can do with apache commons BeanComparator? Or will I have to come up with my own custom tool?</p>

<p>I have a web site devoted to helping people with interactive sessions. It starts with the user clicking [Begin] so this is a consented action. This should (1) open a popup while (2) redirecting the first page to a end page as below : </p>
<pre><code><head>

function openwindow(){window.open("{INTERACTION}","interaction","resizable=0,width=800,height=600,status=0");}</SCRIPT>

<input type="submit" class="button"
onClick="javascript: openwindow()"
value="Begin" />
</FORM>
</body>
</code></pre>
<p>As said, this is not trying to open an unrequested popup but some strains of IE and Chrome appear to be treating it as such. I have been trying to get a fix, most recently digesting <a href="http://stackoverflow.com/questions/668286/detect-blocked-popup-in-chrome">this post</a>. </p>
<p>In it Bobince comments </p>
<blockquote>
<p>these days, you don't really need to ask the question “was my unsolicited popup blocked?”, because the answer is invariably “yes” — all the major browsers have the popup blocker turned on by default. Best approach is only ever to window.open() in response to a direct click, which is almost always allowed.I'm quite happy to buy into this principle because I simply want my popup to open. </p>
</blockquote>
<p>What is causing some browsers to see my code as unsolicited?</p>
<p>I'd appreciate any help you could give me. (as you might have guessed, client side is not my bag and this topic has been bugging me for ages).</p>
<p>Many thanks in advance (and fingers crossed)
