  • Html 5 Time Tag not recognized by IE8 when cloning

    - by matsientst
    I have been having trouble getting IE to recognize the new Time tag in this context. This all works great in FF. Here is the code: var origComment = $('.articleComment:first div'); if (origComment.length > 0) { var commentHtml = origComment.clone(true); commentHtml.find('time').text('today'); var html = '<article class="' + ((side == 'LEFT') ? '' : 'that') + '">' + commentHtml.html() + '</article>'; $(html).insertAfter('.articleComment:last'); The HTML looks something like this: <article class="articleComment that"> <div id="156" class="parent"> <div class="byline"> <p>Posted <time pubdate="pubdate" datetime="2010-05-07T09:11:08">today</time> by<br/> <a class="username" href="/u/matt">matt</a> </p> <p class="report"><a href="#">Report?</a></p> </div> <div class="comment">left</div> </div> </article> IE can find the Time tag but it returns a collection of 2 elements. I assume the beginning and ending. However, I cannot access it to modify it. I have tried val(), html() and text(). I also can't drop to the actual HTMLElement. I can't get(0).innerHTML. But, if I .get(0).tagName it actually is the Time tag I've got. Any ideas? I hope this makes sense.

  • escape exactly what in javascript

    - by Emin
    Hi all, Being a newbie in javascript I came to a situation where I need more information on escaping characters in a string. Basically I know that in order to escape " I need to replace it with \" but what I don't know is for which characters I need to escape a particular string for. Is there a list of these "characters to escape"? or is it any character that is not a-zA-Z0-9 ? In my situation, I don't have control over the content that is being displayed on my page. Users enter some text and save it. I then use a webservice to extract them from the database, build a json array of objects, then iterate the array when I need to display them. In this case, I have - naturally - no idea of what the text the user has entered and therefore for what characters I need to escape. I also use jQuery for this specific project (just in case it has a function I am not aware of, to do what I need) Providing examples would be appreciated but I also want to learn the theory and logic behind it. Hope someone can be of any help.

    - by Nano HE
    Hello. I am parsing a xml document, I need find out the gid (an attribute) value (3810). Based on SelectSingleNode(). I found it is not easy to find the attribute name and it's value.

  • What's the best way to handle layout issues with multi-language support in WPF/XAML?

    - by Tim
    I'm creating a standalone WPF app with multi-language support. I've found some great resources (mostly on SO) on how to store and access the strings as needed. This part is pretty straightforward and doable, but I'm fuzzy on how to take care of screen layout issues. I'm using some custom images to skin up my app for buttons, etc. For instance, here's a button with some text within: <Button Canvas.Left="33" Canvas.Top="484" Style="{StaticResource SmallButtonBase}"> <TextBlock FontSize="20" FontWeight="Bold" TextAlignment="Center" FontFamily="Helvetica"> Enter </TextBlock> </Button> Now here is the same button with text from another language: <Button Canvas.Left="33" Canvas.Top="484" Style="{StaticResource SmallButtonBase}"> <TextBlock FontSize="20" FontWeight="Bold" TextAlignment="Center" FontFamily="Helvetica"> Enterenschtein </TextBlock> </Button> So my question is: What is a good method to prevent this "overflow" situation. I'd like to have XAML take care of any font resizing or indenting that is needed automatically so that I don't have to tweak the UI for each language I'm supporting. Any insight is appreciated!

  • IE7 Debug Issue - Word Breaks in <li>

    - by JCHASE11
    Hello, I am having a very basic problem in IE7 that I cannot seem to fix. If you look at this page: http://vitaminjdesign.com/IAM/company/ you will notice that the vertical nav (ul id="leftcol") is displaying incorrectly in IE7. Each word appears on its own line.

  • Hovering a div shows hidden div - jquery to prototype conversion

    - by phil
    I may get killed for this but I have been trying for a few days using Prototype to show a hidden div when hovering over another div. I have this working fine in jquery but I could use some help porting it over to prototype. The code sample: <script type="text/javascript"> $(document).ready(function(){ $(".recent-question").hover(function(){ $(this).find(".interact").fadeIn(2.0); }, function(){ $(this).find(".interact").fadeOut(2.0); }); }); </script> <div class="recent-question"> <img src="images/new/img-sample.gif" alt="" width="70" height="60" /> <div class="question-text"> <h3>Heading</h3> <p><a href="#">Yadda Yadda Yadda</p> </div> <div class="interact" style="display:none;"> <ul> <li><a href="#">Choice1</a></li> <li><a href="#">Choice2</a></li> <li><a href="#">Choice3</a></li> </ul> </div> </div> So basically when I hover over a recent-question div i would like the div.interact to fade in or appear at all. The above code is for jquery but I am required to use prototype for this project. Any help converting would be greatly appreciated. Thanks!

  • How to speed up a slow UPDATE query

    - by Mike Christensen
    I have the following UPDATE query: UPDATE Indexer.Pages SET LastError=NULL where LastError is not null; Right now, this query takes about 93 minutes to complete. I'd like to find ways to make this a bit faster. The Indexer.Pages table has around 506,000 rows, and about 490,000 of them contain a value for LastError, so I doubt I can take advantage of any indexes here. The table (when uncompressed) has about 46 gigs of data in it, however the majority of that data is in a text field called html. I believe simply loading and unloading that many pages is causing the slowdown. One idea would be to make a new table with just the Id and the html field, and keep Indexer.Pages as small as possible. However, testing this theory would be a decent amount of work since I actually don't have the hard disk space to create a copy of the table. I'd have to copy it over to another machine, drop the table, then copy the data back which would probably take all evening. Ideas? I'm using Postgres 9.0.0. UPDATE: Here's the schema: CREATE TABLE indexer.pages ( id uuid NOT NULL, url character varying(1024) NOT NULL, firstcrawled timestamp with time zone NOT NULL, lastcrawled timestamp with time zone NOT NULL, recipeid uuid, html text NOT NULL, lasterror character varying(1024), missingings smallint, CONSTRAINT pages_pkey PRIMARY KEY (id ), CONSTRAINT indexer_pages_uniqueurl UNIQUE (url ) ); I also have two indexes: CREATE INDEX idx_indexer_pages_missingings ON indexer.pages USING btree (missingings ) WHERE missingings > 0; and CREATE INDEX idx_indexer_pages_null ON indexer.pages USING btree (recipeid ) WHERE NULL::boolean; There are no triggers on this table, and there is one other table that has a FK constraint on Pages.PageId.

  • Logging in to website with saved username and password

    - by DGund
    One of the functions of an app I am making involves logging the user into our Campus Portal website. For ease of use, the user may enter a username and password into the app once, and it will be saved for all future log-ins. When the user clicks a button, the information will automatically be sent to log in, and the website will be displayed in a UIWebView. Let us say that the username and password are each stored in an NSString. How can I use this data to log in to this website programmatically and display the page it in a UIWebView? I know little about posting and forms, so any help is appreciated. Would something like this Stackoverflow answer help? Here's the shell of my code for this - (IBAction)btnGo:(id)sender { username = usernameField.text; password = passwordField.text; if (saveSwitch.isOn) { //Save data if the user wants AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; usernameSaved = username; passwordSaved = password; [appDelegate.listOfPortalCredentials replaceObjectAtIndex:0 withObject:usernameSaved]; [appDelegate.listOfPortalCredentials replaceObjectAtIndex:1 withObject:passwordSaved]; } //Insert username and password to web form, log in to portal //This is where I need help }

  • How to check Internet status in iPhone

    - by Radix
    Hello; I wanted to check whether internet is connected or not using either the SystemConfiguration or the CFNetwork i am not quite sure which one. Then i want to know that if the internet is connected then is it connected through wifi or not. I tried an example where i used the below code -(IBAction) shownetworkStatus { NSURL *url = [NSURL URLWithString:@"www.google.com"]; if (url!=NULL) { lbl.text = @"Connected"; } else { lbl.text = @"notConnected"; } } some say that its not valid as per apple and you have to use the SystemConfiguration Framework, Please let me know what needs to be done. Also i personally think that what i am doing in the above code is not proper as if one day google may also be down due to maintenance or some other factors. Also if you could provide me a link where i could display the name of the WIFI network then it would be really cool. I searched the internet then i got these Reachability.h code which again is a bouncer as i wana learn the concepts not copy paste them Thanks and Regards Radix

  • Write to the second line of a PHP file

    - by Woz
    I have a php file that I want to add an include path to on the second line. I need to open the file and inset a line of code on line 2. I have tried a few techniques none of which are working but I think it has something to do with the text I am trying to write and possibly not escaping character correctly as I am not too familiar with file writing. So here is the file I want to write to: $file = $_SERVER['DOCUMENT_ROOT'].'/'.$domaindir.'/test.php'; Here is the piece of text I want to insert into the file: $dbfile = "include('".$_SERVER['DOCUMENT_ROOT']."/".$domaindir."/web_".$dbname.".inc.php');"; Then what I was doing was a string replace but all it did was bump the "session_start();" bit to a newline! Can anyone point me in the direction of a tutorial that might tell me how to insert this into the second line of my php file or indeed if anyone has any ideas? I can say for sure that the path to the PHP file is fully tested so i know its not that the file is not being open or written to. Any ideas would be much appreciated. Thanks in advance.

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • rendering a TextView in a Bitmap for an android widget

    - by foke
    I'm building a widget which displays some text. By widget I mean the kind which lies on the desktop. The problem is that I want to change text's font at runtime. There is several textview I would like, at runtime, to set the first as bold, the second blue and italic for example, etc. I came up with this : TextView tv = new TextView(context); tv.setText(stringToDisplay); tv.setTextColor(0xa00050ff); // example tv.setTextSize(30); // example Bitmap b = loadBitmapFromView(tv); updateViews.setImageViewBitmap(R.id.id_of_the_imageview, b); with private static Bitmap loadBitmapFromView(View v) { Bitmap b = Bitmap.createBitmap(v.getLayoutParams().width, v.getLayoutParams().height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height); v.draw(c); return b; } but it wont work (NullPointerException on first line of loadBitmap), until I replace v.getLayoutParams().width, v.getLayoutParams().height by fixed sizes like 250, 50 Bitmap b = Bitmap.createBitmap(250, 50, Bitmap.Config.ARGB_8888); // ... v.layout(0, 0, 250, 50); But that's not a good solution ... so I tried this : LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View row = li.inflate(R.layout.widget_text, null); TextView tv = (TextView) row.findViewById(R.id.id_of_the_textview); widget_text being a layout similar to the displayed one but with TextViews instead of ImageViews, in the hope to get some size information out of it .. but it's not working and I get this exception : 01-02 17:35:06.001: ERROR/AndroidRuntime(11025): Caused by: java.lang.IllegalArgumentException: width and height must be > 0 on the call to Bitmap.createBitmap() so, someone could point me in the right direction?

  • Emulating a computer running MS-DOS

    - by Richard
    Writing emulators has always fascinated me. Now I want to write an emulator for an IBM PC and run MS-DOS on it (I've got the floppy image files). I have good experience in C++ and C and basic knowledge of assembler and the architecture of a CPU. I also know that there are thousands of emulators out there doing exactly what I want to do, but I'd be doing this for pure joy only. How much work do I have to expect? (If my goal is to boot DOS and create a text file with it, all emulated) What CPU should I emulate ? Where can I find documentation on how the machine code is organized and which opcodes mean what, so I can unpack and execute them correctly with my emulator? Does MS-DOS still run on the newest generations of processors? Would it theoretically be able to natively run on a 64-bit AMD Phenom 2 processor w/ a modern mainboard, HDD, RAM, etc.? What else, besides emulating the CPU, could be an important factor (in terms of difficulty)? I would only aim for outputting / inputting text to the system via the host system's console, no sound or other more advanced IO etc. Have you written an emulator yet? What was your first one for? How hard was it? Do you have any special tips for me? Thanks in advance

  • Animate absolutely positioned div, but stop if a condition is true?

    - by Alex
    Hello all, I have a div which I place at the top right-hand corner of a website, absolutely positioned at top: 0px and right : 0px. I want to use jquery's animate function to animate the div left or right a certain amount when a button is clicked, but stop the animation if at anytime, the div's offset to the left or right is less than a certain number. I want to do this to accomodate users who click the left or right buttons more than once, so that the div does not fly out of sight. How does one accomplish this? Below is my relevant css, html, and jquery code: CSS: #scorecardTwo { position:absolute; padding:5px; width: 300px; background-color:#E1E1E1; right:0px; top:0px; display:none; } HTML: <div id = "scorecardTwo"> <span id = "dealHolder"><a href="some/link">some text</a></span> <br /> <span id = "scoreHolder">some text</span> <br /> <button type="button" id="moveLeft">Left</button>&nbsp;<button type="button" id="moveRight">Right</button> </div> jQuery (at the moment): $("#scorecardTwo").fadeIn("slow"); $("#moveLeft").bind("click", function() { $("#scorecardTwo").animate({"right":"+=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? }); $("#moveRight").bind("click", function() { $("#scorecardTwo").animate({"right" : "-=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? });

  • Choosing approach for an IM client-server app

    - by John
    Update: totally re-wrote this to be more succint. I'm looking at a new application, one part of which will be very similar to standard IM clients, i.e text chat, ability to send attachments, maybe some real-time interaction like a multi-user whiteboard. It will be client-server, i.e all traffic goes through my central server. That means if I want to support cross-communication with other IM systems, I am still free to pick any protocol for my own client<--server communication - my server can use XMPP or whatever to talk to other systems. Clients are expected to include desktop apps, but probably also browser-based as well either through Flex/Silverlight or HTML/AJAX. I see 3 options for my own client-server communication layer: XMPP. The benefits are clients already exist as do open-source servers. However it requires the most up-front research/learning and also appears like it might raise legal issues due to GPL. Custom sockets. A server app makes connections with the clients, allowing any text/binary data to be sent very fast. However this approach requires building said server from scratch, and also makes a JS client tricky Servlets (or similar web server). Using tried and tested Java web-stack, clients send HTTP requests similar to AJAX-based websites. The benefit is the server is easy to write using well-established technologies, and easy to talk to. But what restrictions would this bring? Is it appropriate technology for real-time communication? Advice and suggests are welcome, especially what pros and cons surround using a web-server approach as compared to a socket-based approach.

  • How to have screen revert to BLACK between pages?

    - by user340667
    0 Hi - I tried out the Background Image Scaling script and with Cybr's update it works like magic. It SCALES the image perfectly. No distortion. BUT, my image isn't "computer friendly". I.e.: Not 1024 X 768 or even close to that. (Heck, my monitor has a wide screen, so it isn't 1024 X 768 either! Is anybody's anymore?) Anyhow, this creates a problem inasmuch as, unless I size the window from the bottom up it ends up with a white "stripe" beneath it. What I would REALLY like for it to do is have that white to be BLACK. My "usual" BG color/text etc. code is like: ""body bgcolor="#000000" text="#fcba1e" link="#0000ff" vlink="#800080" alink="#ff0000"" (Site won't let me add the arrows here.) I've tried inserting this in various places with no success. Any ideas for a workaround would surely be appreciated ! Thanks ! Bill

  • Error with zoomStartTime and AnnotatedTimeLine

    - by user973025
    I'm a bit of a beginner with Javascript, but last month I had a working Google chart linked to a Google Docs file, which uses a start date for the graph at 90 days before the current date. I checked the page today and in Chrome I get the message "Object # has no method 'getTime'", and in Firefox I get the message "b.zoomStartTime[y] is not a function". Both stop the graph from loading. I have simplified the code to help me with the error, but I'm not getting anywhere... Here's the code: <script type="text/javascript"> var oldDate = new Date(); oldDate.setDate(oldDate.getDate() - 90); </script> <script type="text/javascript" src="//ajax.googleapis.com/ajax/static/modules/gviz/1.0/chart.js"> { "dataSourceUrl": "//docs.google.com/spreadsheet/tq?key=0AkQH6d2CUv_qdDhwd3gtZzdTVFlNX3AwX2xUSUVuclE&transpose=0&headers=-1&range=A1%3AB2436&gid=0&pub=1", "options": { "zoomStartTime": oldDate, "width": 650, "height": 371 }, "chartType": "AnnotatedTimeLine", } </script> Any ideas would be hugely appreciated. David.
