  • Where should JavaScript be put?

    - by NessDan
    I've been doing a little JavaScript (well, more like jQuery) for a while now and one thing I've always been confused about is where I should put my scripts, in the <head> tag or in the <body> tag. If anyone could clarify this issue, that'd be great. An example of what should go where would be perfect.

  • Marking Changes to database...

    - by KoolKabin
    Hi guys... I am developing application to be run in central server and distributed computers. I am supposed to write application to backup the data from distributed machines and merge it in central server. I thought of compressing whole local database and sending it to server for merging. But as the database size grows the size of compress file also began to grow. So is there any way to merge data in central server without sending whole database. I need to do it on daily basis. Daily take backup and send to server

  • Unexpected behavior of IntentService

    - by kknight
    I used IntentService in my code instead of Service because IntentService creates a thread for me in onHandleIntent(Intent intent), so I don't have to create a Thead myself in the code of my service. I expected that two intents to the same IntentSerivce will execute in parallel because a thread is generated in IntentService for each invent. But my code turned out that the two intents executed in sequential way. This is my IntentService code: public class UpdateService extends IntentService { public static final String TAG = "HelloTestIntentService"; public UpdateService() { super("News UpdateService"); } protected void onHandleIntent(Intent intent) { String userAction = intent .getStringExtra("userAction"); Log.v(TAG, "" + new Date() + ", In onHandleIntent for userAction = " + userAction + ", thread id = " + Thread.currentThread().getId()); if ("1".equals(userAction)) { try { Thread.sleep(20 * 1000); } catch (InterruptedException e) { Log.e(TAG, "error", e); } Log.v(TAG, "" + new Date() + ", This thread is waked up."); } } } And the code call the service is below: public class HelloTest extends Activity { //@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Intent selectIntent = new Intent(this, UpdateService.class); selectIntent.putExtra("userAction", "1"); this.startService(selectIntent); selectIntent = new Intent(this, UpdateService.class); selectIntent.putExtra("userAction", "2"); this.startService(selectIntent); } } I saw this log message in the log: V/HelloTestIntentService( 848): Wed May 05 14:59:37 PDT 2010, In onHandleIntent for userAction = 1, thread id = 8 D/dalvikvm( 609): GC freed 941 objects / 55672 bytes in 99ms V/HelloTestIntentService( 848): Wed May 05 15:00:00 PDT 2010, This thread is waked up. V/HelloTestIntentService( 848): Wed May 05 15:00:00 PDT 2010, In onHandleIntent for userAction = 2, thread id = 8 I/ActivityManager( 568): Stopping service: com.example.android/.UpdateService The log shows that the second intent waited the first intent to finish and they are in the same thread. It there anything I misunderstood of IntentService. To make two service intents execute in parallel, do I have to replace IntentService with service and start a thread myself in the service code? Thanks.

  • Display HTML code in HTML

    - by Steven
    Is there a way to show HTML code-snippets on a webpage without needing to replace each < with &lt; and with &gt;? In other words, is there some tag which simply says "Don't render html until you hit the closing tag?"

  • Silverlight 4 DataBinding: Binding to ObservableCollection<string> not working anymore

    - by Kurt
    Upgrading from SL3 - SL4. First problem: this throws a parser exception: <StackPanel Name={Binding} /> (same with x:Name) Collection is ObservableCollection<string>. Worked fine in SL3. So it seems that SL4 doen't allow binding to the Name property. Huh? So: changed to <StackPanel Tag={Binding} /> ... since I just need to ID the control in code behind. So here's the bug ('cuz this has got to be a bug!): In this frag, AllAvailableItems is an ObservableCollection<string>: <ItemsControl Name="lbItems" ItemsSource="{Binding AllAvailableItems}" Height="Auto" Width="Auto" BorderBrush="Transparent" BorderThickness="0" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="12,6,0,0"> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <CheckBox Tag="{Binding}" Checked="ItemChecked_Click" Unchecked="ItemUnchecked_Click" Style="{StaticResource CheckBoxStyle}" Grid.Row="0"> <CheckBox.Content> <TextBlock Text="{Binding}" Style="{StaticResource FormLJustStyle}" /> </CheckBox.Content> </CheckBox> <StackPanel Tag="{Binding}" Orientation="Vertical" Grid.Row="1"> <configControls:ucLanguage /> <!-- simple user control --> </StackPanel> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> In the code behind, I use a recursive function to find the Dependency object with either the Name or Tag property provided: public static T FindVisualChildByName<T>(DependencyObject parent, string name, DependencyProperty propToUse) where T : DependencyObject { for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++) { var child = VisualTreeHelper.GetChild(parent, i); string controlName = child.GetValue(propToUse) as string; if (controlName == name) { return child as T; } else { T result = FindVisualChildByName<T>(child, name, propToUse); if (result != null) return result; } } return null; } OK, get this: in the code behind, I can get the control that is ORDERED FIRST in the XAML! In other words, if I put the CheckBox first, I can retrieve the CheckBox, but no StackPanel. And vice-versa. This all worked fine in SL3. Any help, ideas ... ? Thanks - Kurt

  • Git: hide commit messages on remote repo

    - by Sebastian Bechtel
    Hi, I don't know how to bring my problem on the point so I try to explain it a bit ;-) When working with git on my local maschine I usually commit a lot. For this I use topic branches. Then I merge such a topic branch into a branch called develop which will be pushed to a remote repo. I always merge with --no-ff so their is always a commit for my whole topic. Now I'd like to only push this commit with a specified description what I did on the whole in this branch. I would prefer this because you can look at the commit history on the server and see directly what happend and don't need to read every single commit. And for my local work I would have the full history if I want to reset my branch or something similar. I don't know if their is a way to do this in git but it would be very useful for me so I give it a try to ask you ;-) Best regards, Sebastian

  • Would Apache running on port 8080 prevent dynamically loaded scripts in JavaScript?

    - by editor
    Had a nice PHP/HTML/JS prototype working on my personal Linode, then tried to throw it into a work machine. The page adds a script tag dynamically with some JavaScript. It's a bunch of Google charts that update based on different timeslices. That code looks something like this: // jQuery $.post to send the beginning and end timestamps $.post("channel_functions.php", data_to_post, function(data){ // the data that's returned is the javascript I want to load var script = document.createElement('script'); var head= document.getElementsByTagName('head')[0]; var script= document.createElement('script'); var text = document.createTextNode(data); script.type= 'text/javascript'; script.id = 'chart_data'; script.appendChild(text); // Adding script tag to page head.appendChild(script); // Call the function I know were present in the script tag loadTheCharts(); }); function loadTheCharts() { // These are the functions that were loaded dynamically // By this point the script tag is supposed be loaded, added and eval'd function1(); function2(); } Function1() and function2() don't exist until they get added to the dom, but I don't call loadTheCharts() until after the $.post has run so this doesn't seem to be a problem. I'm one of those dirty PHP coders you mother warned you about, so I'm not well versed in JavaScript beyond what I've read in the typical go-to O'Reilly books. But this code worked fine on my personal dev server, so I'm wondering why it wouldn't work on this new machine. The only difference in setup, from what I can tell, is that the new machine is running on port 8080, so it's 192.168.blah.blah:8080/index.php instead of nicedomain.com/index.php. I see the code was indeed added to the dom when I use webmaster tools to "view generated source" but in Firebug I get an error like "function2() is undefined" even though my understanding was that all script tags are eval'ed when added to . My question: Given what I've laid out, and that the machine is running on :8080, is there a reason anyone can think of as to why a dynamically loaded function like function2() would be defined on the Linode and not on the machine running Apache on 8080?

  • Bulk inserts into sqlite db on the iphone...

    - by akaii
    I'm inserting a batch of 100 records, each containing a dictonary containing arbitrarily long HTML strings, and by god, it's slow. On the iphone, the runloop is blocking for several seconds during this transaction. Is my only recourse to use another thread? I'm already using several for acquiring data from HTTP servers, and the sqlite documentation explicitly discourages threading with the database, even though it's supposed to be thread-safe... Is there something I'm doing extremely wrong that if fixed, would drastically reduce the time it takes to complete the whole operation? NSString* statement; statement = @"BEGIN EXCLUSIVE TRANSACTION"; sqlite3_stmt *beginStatement; if (sqlite3_prepare_v2(database, [statement UTF8String], -1, &beginStatement, NULL) != SQLITE_OK) { printf("db error: %s\n", sqlite3_errmsg(database)); return; } if (sqlite3_step(beginStatement) != SQLITE_DONE) { sqlite3_finalize(beginStatement); printf("db error: %s\n", sqlite3_errmsg(database)); return; } NSTimeInterval timestampB = [[NSDate date] timeIntervalSince1970]; statement = @"INSERT OR REPLACE INTO item (hash, tag, owner, timestamp, dictionary) VALUES (?, ?, ?, ?, ?)"; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(database, [statement UTF8String], -1, &compiledStatement, NULL) == SQLITE_OK) { for(int i = 0; i < [items count]; i++){ NSMutableDictionary* item = [items objectAtIndex:i]; NSString* tag = [item objectForKey:@"id"]; NSInteger hash = [[NSString stringWithFormat:@"%@%@", tag, ownerID] hash]; NSInteger timestamp = [[item objectForKey:@"updated"] intValue]; NSData *dictionary = [NSKeyedArchiver archivedDataWithRootObject:item]; sqlite3_bind_int( compiledStatement, 1, hash); sqlite3_bind_text( compiledStatement, 2, [tag UTF8String], -1, SQLITE_TRANSIENT); sqlite3_bind_text( compiledStatement, 3, [ownerID UTF8String], -1, SQLITE_TRANSIENT); sqlite3_bind_int( compiledStatement, 4, timestamp); sqlite3_bind_blob( compiledStatement, 5, [dictionary bytes], [dictionary length], SQLITE_TRANSIENT); while(YES){ NSInteger result = sqlite3_step(compiledStatement); if(result == SQLITE_DONE){ break; } else if(result != SQLITE_BUSY){ printf("db error: %s\n", sqlite3_errmsg(database)); break; } } sqlite3_reset(compiledStatement); } timestampB = [[NSDate date] timeIntervalSince1970] - timestampB; NSLog(@"Insert Time Taken: %f",timestampB); // COMMIT statement = @"COMMIT TRANSACTION"; sqlite3_stmt *commitStatement; if (sqlite3_prepare_v2(database, [statement UTF8String], -1, &commitStatement, NULL) != SQLITE_OK) { printf("db error: %s\n", sqlite3_errmsg(database)); } if (sqlite3_step(commitStatement) != SQLITE_DONE) { printf("db error: %s\n", sqlite3_errmsg(database)); } sqlite3_finalize(beginStatement); sqlite3_finalize(compiledStatement); sqlite3_finalize(commitStatement);

  • Xpath help. Get childnode with variable name

    - by Kim Andersen
    I have the following XML: <StatsContainer> <Variant1>0</Variant1> <Variant2>0.5</Variant2> <Variant3>1.2</Variant3> <Variant4>4.1</Variant4> <Variant5>93.9</Variant5> <Variant6>0.3</Variant6> <Variant7>0</Variant7> <Variant8>0</Variant8> <Variant9>0</Variant9> <Variant10>0</Variant10> <Variant11>0</Variant11> <Variant12>0</Variant12> <GlobalVariant1>4.6</GlobalVariant1> <GlobalVariant2>40.4</GlobalVariant2> <GlobalVariant3>13.8</GlobalVariant3> <GlobalVariant4>2.8</GlobalVariant4> <GlobalVariant5>35.6</GlobalVariant5> <GlobalVariant6>2.8</GlobalVariant6> <GlobalVariant7>0</GlobalVariant7> <GlobalVariant8>0</GlobalVariant8> <GlobalVariant9>0</GlobalVariant9> <GlobalVariant10>0</GlobalVariant10> <GlobalVariant11>0</GlobalVariant11> <GlobalVariant12>0</GlobalVariant12> <MosaicType>Boligtype</MosaicType> <OverRepresentedVariant>5</OverRepresentedVariant> </StatsContainer> As you can see I have a number in the "OverRepresentedVariant"-tag. This number can change from time to time. What i Need is to grab the "Variant"-tag with the right number. In the above case I need to get the value from the "Variant5"-tag (93.9). Tomorrow the "OverRepresentedVariant"-value might have changed to 3, this would mean that I should now grab the "Variant3"-value instead. So this is what I got. I have a variable called $btOver which contains the above XML. I also have a variable called $btId which contains the "OverRepresentedVariant"-value like this: <xsl:variable name="btId" select="$btOver/OverRepresentedVariant" /> So now I need some help finding the Variant-tags with the right ID. The tags that I need will always be named "Variant" followed by an id. So how can I get the right tag? Thanks a lot in advance folks. /Kim Andersen

  • Lazy loading the addthis script? (or lazy loading external js content dependent on already fired eve

    - by Keith Bentrup
    I want to have the addthis widget available for my users, but I want to lazy load it so that my page loads as quickly as possible. However, after trying it via a script tag and then via my lazy loading method, it appears to only work via the script tag. In the obfuscated code, I see something that looks like it's dependent on the DOMContentLoaded event (at least for firefox). Since the DOMContentLoaded event has already fired, the widget doesn't render properly. What to do? I could just use a script tag (slower)... or could I fire (in a cross browser way) the DOMContentLoaded (or equivalent) event? I have a feeling this may not be possible b/c I believe that (like jQuery) there are multiple tests of the content ready event, and so multiple simulated events would have to occur. Nonetheless, this is an interesting problem b/c I have seen a couple widgets now assume that you are including their stuff via static script tags. It would be nice if they wrote code that was more useful to developers concerned about speed, but until then, is there a work around?? And/or are any of my assumptions wrong? Edit: Because the 1st answer to the question seemed to miss the point of my problem, I wanted to clarify the situation. This is about a specific problem. I'm not looking for yet another lazy load script or check if some dependencies are loaded script. Specifically this problem deals with external widgets that you do not have control over and may or may not be obfuscated delaying the load of the external widgets until they are needed or at least, til substantially after everything else has been loaded including other deferred elements b/c of the how the widget was written, precludes existing, typical lazy loading paradigms While it's esoteric, I have seen it happen with a couple widgets - where the widget developers assume that you're just willing to throw in another script tag at the bottom of the page. I'm looking to save those 500-1000 ms** though as numerous studies by yahoo, google, and amazon show it to be important to your user's experience. **My testing with hammerhead and personal experience indicates that this will be my savings in this case.

  • Java - is it possible to read a file line by line, stop, and then immediately start reading bytes wh

    - by hatorade
    I'm having an issue trying to parse the ascii part of a file, and once I hit the end tag, IMMEDIATELY start reading in the bytes from that point on. Everything I know in Java to read off a line or a whole word creates a buffer, which ruins any chance of getting the bytes immediately following my stop point. Is the only way to do this read in byte-by-byte, find new-lines, reconstruct everything prior to the new-line, see if it's my end tag, and go from there?
