  • How can you push a new view with a grouped table?

    - by Tanner
    Hi All, Ive been trying to push a new view when a cell is tapped but absolutely nothing happens. I figured grouped style pushed the same as plain. Here is my code: -(void)viewDidLoad { [super viewDidLoad]; contactArray = [[NSArray alloc] initWithObjects:@"iPhone",@"iPod",@"MacBook",@"MacBook Pro",nil]; shareArray = [[NSArray alloc] initWithObjects:@"Flex",@"AIR",@"PhotoShop",@"Flash",nil]; } -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; } // Customize the number of rows in the table view. -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if(section == 0) return [contactArray count]; else return [shareArray count]; } -(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{ if(section == 0){ return @"Contact"; }else{ return @"Share"; } } -(NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section{ if(section == 0){ return @"Footer for Apple Products"; }else{ return @"Footer for Adobe Softwares"; } } // Customize the appearance of table view cells. -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } // Set up the cell... if(indexPath.section == 0){ cell.text = [contactArray objectAtIndex:indexPath.row]; }else{ cell.text = [shareArray objectAtIndex:indexPath.row]; } return cell; } -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //NextViewController *nextController = [[NextViewController alloc] initWithNibName:@"NextView" bundle:nil]; //[self.navigationController pushViewController:nextController animated:YES]; if([contactArray objectAtIndex:indexPath.row] == @"iPhone"){ LandscapeHydrogen *abo = [[LandscapeHydrogen alloc] initWithNibName:@"LandscapeHydrogen" bundle:nil]; [self.navigationController pushViewController:abo animated:NO]; [abo release]; } } Any help is appreciated.

  • string auto splitting in each loop - jquery

    - by sluggerdog
    I have the following jquery code that is looping through the returned json data, for some reason is it splitting the suburb by a space when being assigned as the value but not as the text, I cannot work out why this is happening. MY CODE $.each(data , function( index, obj ) { $.each(obj, function( key, value ) { var suburb = $.trim(value['mcdl01']); var number = $.trim(value['mcmcu']); $("#FeedbackBranchName").append("<option value=" + suburb + ">" + suburb + " (" + number + ")</option>"); }); }); SAMPLE RETURNED RESULTS <option **value="AIRLIE" beach=""**>AIRLIE BEACH (4440)</option> <option value="ASHMORE">ASHMORE (4431)</option> <option **value="BANYO" commercial=""**>BANYO COMMERCIAL (4432)</option> <option value="BEENLEIGH">BEENLEIGH (4413)</option> <option value="BERRIMAH">BERRIMAH (4453)</option> <option **value="BOWEN" hills=""**>BOWEN HILLS (4433)</option> Notice how for AIRLEE BEACH, BANYO COMMERICAL AND BOWN HILLS the second word has been separated out from the value attribute but it's fine at the text level. Anyone have any idea why this might happen? Thanks

  • Send html array as post variable using Request.JSON

    - by ian
    I have an html: First name: <input type='text' name='first_name' value='' /><br/> Last name: <input type='text' name='last_name' value='' /><br/> <input type='checkbox' name='category[]' value='Math' /> Math<br/> <input type='checkbox' name='category[]' value='Science' /> Science<br/> <input type='checkbox' name='category[]' value='History' /> History<br/> etc..... I want to send(using post method) the selected categories(category[]) via mootools ajax so that if I dump the $_POST variable in the server I will get something like: array(1) { [category]=> array(2) { [0]=> string(4) "Math" [1]=> string(7) "History" } } What should be the javascript(mootools) code for it? Below is my partial code. new Request.JSON({url: '/ajax_url', onSuccess: function(){ alert('success'); } }).post(???); Note that I don't want to send first_name and last_name fields. I only want to send the category field which is an html array.

  • Updating an input value with Jquery

    - by Evan
    I have a form with a few fields, one of which should be updated based on the value of another. The value of the first is POSTed to another URL, and the returned value should be used to fill the second field. Here's the code: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script> function lookup(rid) { $.get("/handler?rid=" + $("input#rid").val(), function(update_rid){ $("#name").val(html(update_rid)); }) } </script> <form name="new_alert"> <input type="text" name="rid" id="rid" onkeyup="lookup(this.value);"> <br /> <input type="text" name="name" id="name"> </form> The POST works fine, and the correct data is returned from /hander, which I confirmed by making a test and filling it using $("#testdiv").html(update_rid); So it seems like the problem is in the way I'm trying to update the value, but I can't get past that.

  • subscripts and superscripts in SVG

    - by peter.murray.rust
    I am trying to display sub- and superscripts with SVG using the following code from this site <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <g> <text x = "10" y = "25" font-size = "20"> <tspan> e = mc <tspan baseline-shift = "super">2</tspan> </tspan> <tspan x = "10" y = "60"> T <tspan baseline-shift = "sub">i+2</tspan> =T <tspan baseline-shift = "sub">i</tspan> + T <tspan baseline-shift = "sub">i+1</tspan> </tspan> </text> </g> but the sub/superscripts do not display in IE or Firefox. Is this unimplemented or is there another problem? [Are you able to see the subscripts displayed properly?]

  • how to create a mootools 1.1 function with array

    - by liz
    i have a series of select lists, that i am using to populate text boxes with ids. so you click a select option and another text box is filled with its id. with just one select/id pair this works fine, but i have multiples, and the only thing that changes is the id of the select and input.. in fact just the ending changes, the inputs all start with featredproductid and the select ids all start with recipesproduct and then both end with the category. i know that listing this over and over for each category is not the way to do it. i think i need to make an array of the categories var cats = ['olive oil', "grains", "pasta"] and then use a forEach function? maybe? here is the clunky code window.addEvent('domready', function() { $('recipesproductoliveoil').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidoliveoil").setProperties({ value: pidselected}); ; }); $('recipesproductgrains').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidgrains").setProperties({ value: pidselected}); ; }); $('recipesproductpasta').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidpasta").setProperties({ value: pidselected}); ; }); $('recipesproductpantry').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidpantry").setProperties({ value: pidselected}); ; }); }); keep in mind this is mootools 1.1 (no i cant update it sorry). i am sure this is kind of basic, something i seem to have wrapping my brain around. but i am quite sure doing it as above is not really good...

  • CSS to specify positions over a scanned document

    - by itsols
    I'm trying to write the CSS rules to position text over a scanned document. Reason: The document is a pre-printed form. I am trying to position the text on-screen so that it relates to the 'spaces' on the actual form. Issue: Although I position the values using centimeters, they don't seem to get aligned with the ones on the actual page. I can see this misalignment since my scanned image is in the background of the page. What I've tried: I used a ruler to physically measure the locations and specify them with CSS. But on-screen, it doesn't tally. I used the scanned image to position the CSS values. Then the printout is not correct. I even scaled the scanned page using Inkscape to the exact dimensions in centimeters and took into account all margins, etc... What I need: I am trying to correctly show the output values on-screen AND have them print in the correct manner as well. I know that using two CSS sheets (one for print) is an option. But I'm developing this program away from where the actual printing is to be done. So is there a convenient way of matching the exact screen locations with those on the actual/final prinout? Thanks!

  • Dynamic TextBox on LinkButton click

    - by Alex Peta
    I am creating dynamic TextBoxes in a page by clicking a LinkButton. However, after that, if the page is submitted, I can't find the items created dynamically, thus, can't send the information to the database. protected void lbAddTag_Click(object sender, EventArgs e) { for (int i = 0; i < 3;i++ ) { CreateTextBox("txtTag-" + i.ToString()); } } private void CreateTextBox(string ID) { TextBox txt = new TextBox(); txt.ID = ID; txt.Width = Unit.Pixel(300); //txt.TextChanged += new EventHandler(OnTextChanged); txt.AutoPostBack = false; tagsPanel.Controls.Add(txt); Literal lt = new Literal(); lt.Text = "<br /><br />"; tagsPanel.Controls.Add(lt); } If I put: foreach (Control c in tagsPanel.Controls) { if (c is TextBox) { lblError.Text += c.ClientID + " , "; } } in the lbAddTag_Click method I can see the items, and they exist, but if I submit the page and try to insert the values in the database nothing... Any hint is much appreciated.

  • django join-like expansion of queryset

    - by jimbob
    I have a list of Persons each which have multiple fields that I usually filter what's upon, using the object_list generic view. Each person can have multiple Comments attached to them, each with a datetime and a text string. What I ultimately want to do is have the option to filter comments based on dates. class Person(models.Model): name = models.CharField("Name", max_length=30) ## has ~30 other fields, usually filtered on as well class Comment(models.Model): date = models.DateTimeField() person = models.ForeignKey(Person) comment = models.TextField("Comment Text", max_length=1023) What I want to do is get a queryset like Person.objects.filter(comment__date__gt=date(2011,1,1)).order_by('comment__date') send that queryset to object_list and be able to only see the comments ordered by date with only so many objects on a page. E.g., if "Person A" has comments 12/3/11, 1/2/11, 1/5/11, "Person B" has no comments, and person C has a comment on 1/3, I would see: "Person A", 1/2 - comment "Person C", 1/3 - comment "Person A", 1/5 - comment I would strongly prefer not to have to switch to filtering based on Comments.objects.filter(), as that would make me have to largely repeat large sections of code in the both the view and template. Right now if I tried executing the following command, I will get a queryset returning (PersonA, PersonC, PersonA), but if I try rendering that in a template each persons comment_set will contain all their comments even if they aren't in the date range. Ideally they're would be some sort of functionality where I could expand out a Person queryset's comment_set into a larger queryset that can be sorted and ordered based on the comment and put into a object_list generic view. This normally is fairly simple to do in SQL with a JOIN, but I don't want to abandon the ORM, which I use everywhere else.

  • Extract history from Korn shell

    - by Luc
    I am not happy about the history file in binary format of the Korn shell. I like to "collect" some of my command lines, many of them actually, and for a long time. I'm talking about years. That doesn't seem easy in Korn because the history file is not plain text so I can't edit it, and a lot of junk is piling up in it. By "junk" I mean lines that I don'twant to keep, like 'cat' or 'man'. So I added these lines to my .profile: fc -ln 1 9999 ~/khistory.txt source ~/loghistory.sh ~/khistory.txt loghistory.sh contains a handful of sed and sort commands that gets rid of a lot of the junk. But apparently it is forbidden to run fc in the .profile file. I can't login whenever I do, the shell exits right away with signal 11. So I removed that 'fc -l' line from my .profile file and added it to the loghistory.sh script, but the shell still crashes. I also tried this line in my .profile: strings ~/.sh_history ~/khistory.txt source ~/loghistory.sh That doesn't crash, but the output is printed with an additional, random character in the beginning of many lines. I can run 'fc -l' on the command line, but that's no good. I need to automate that. But how? How can I extract my ksh history as plain text? TIA

  • Reading strings and integers from .txt file and printing output as strings only

    - by screename71
    Hello, I'm new to C++, and I'm trying to write a short C++ program that reads lines of text from a file, with each line containing one integer key and one alphanumeric string value (no embedded whitespace). The number of lines is not known in advance, (i.e., keep reading lines until end of file is reached). The program needs to use the 'std::map' data structure to store integers and strings read from input (and to associate integers with strings). The program then needs to output string values (but not integer values) to standard output, 1 per line, sorted by integer key values (smallest to largest). So, for example, suppose I have a text file called "data.txt" which contains the following three lines: 10 dog -50 horse 0 cat -12 zebra 14 walrus The output should then be: horse zebra cat dog walrus I've pasted below the progress I've made so far on my C++ program: #include <fstream> #include <iostream> #include <map> using namespace std; using std::map; int main () { string name; signed int value; ifstream myfile ("data.txt"); while (! myfile.eof() ) { getline(myfile,name,'\n'); myfile >> value >> name; cout << name << endl; } return 0; myfile.close(); } Unfortunately, this produces the following incorrect output: horse cat zebra walrus If anyone has any tips, hints, suggestions, etc. on changes and revisions I need to make to the program to get it to work as needed, can you please let me know? Thanks!

  • MySQL SELECT combining 3 SELECTs INTO 1

    - by Martin Tóth
    Consider following tables in MySQL database: entries: creator_id INT entry TEXT is_expired BOOL other: creator_id INT entry TEXT userdata: creator_id INT name VARCHAR etc... In entries and other, there can be multiple entries by 1 creator. userdata table is read only for me (placed in other database). I'd like to achieve a following SELECT result: +------------+---------+---------+-------+ | creator_id | entries | expired | other | +------------+---------+---------+-------+ | 10951 | 59 | 55 | 39 | | 70887 | 41 | 34 | 108 | | 88309 | 38 | 20 | 102 | | 94732 | 0 | 0 | 86 | ... where entries is equal to SELECT COUNT(entry) FROM entries GROUP BY creator_id, expired is equal to SELECT COUNT(entry) FROM entries WHERE is_expired = 0 GROUP BY creator_id and other is equal to SELECT COUNT(entry) FROM other GROUP BY creator_id. I need this structure because after doing this SELECT, I need to look for user data in the "userdata" table, which I planned to do with INNER JOIN and select desired columns. I solved this problem with selecting "NULL" into column which does not apply for given SELECT: SELECT creator_id, COUNT(any_entry) as entries, COUNT(expired_entry) as expired, COUNT(other_entry) as other FROM ( SELECT creator_id, entry AS any_entry, NULL AS expired_entry, NULL AS other_enry FROM entries UNION SELECT creator_id, NULL AS any_entry, entry AS expired_entry, NULL AS other_enry FROM entries WHERE is_expired = 1 UNION SELECT creator_id, NULL AS any_entry, NULL AS expired_entry, entry AS other_enry FROM other ) AS tTemp GROUP BY creator_id ORDER BY entries DESC, expired DESC, other DESC ; I've left out the INNER JOIN and selecting other columns from userdata table on purpose (my question being about combining 3 SELECTs into 1). Is my idea valid? = Am I trying to use the right "construction" for this? Are these kind of SELECTs possible without creating an "empty" column? (some kind of JOIN) Should I do it "outside the DB": make 3 SELECTs, make some order in it (let's say python lists/dicts) and then do the additional SELECTs for userdata? Solution for a similar question does not return rows where entries and expired are 0. Thank you for your time.

  • Is hardware accelerated CSS3 in Safari 4 & 5 broken, or my CSS and JS?

    - by Dan Forys
    Hi all, I've created a somewhat silly site that shows you the expected weather forecast for any city in the World. On webkit based browsers, when the weather is sunny a sun with CSS3 animated rotated sunbeams appears. This works fine on Chrome. An example (sunny, at the moment) page is: http://willitraintoday.co.uk/iceland/reykjavik/ However, when viewed in Safari 4 or 5 on Mac Snow Leopard, when the sun appears the sky background appears over it. Weirder still, as the cloud containing the advert moves across the sky, it squashes the main text. When the cloud reaches the left edge, the text appears wider than normal and starts squashing down again. I've tried: - Disabling the CSS3 animation; it works fine in Safari - Juggling the z-index of various elements; to no avail Is there something up with my Javascript or CSS, or is the hardware accelerated snow leopard Safari broken in this case? It seems not to happen in Safari 4 on Leopard, but I don't have Leopard any more to test myself. Grateful for any opinions!

  • Why might a silverlight ListBox on Windows Phone not allow me scroll all the way down to the bottom?

    - by Byron Sommardahl
    I have a ListBox in a grid that gets databound when the page loads... pretty straightforward. The problem I'm having is that, after the box is databound, I can scroll... but not all the way to the bottom of the list. It stops an item or two short and won't let me scroll anymore. Here's the listbox XAML: <Grid x:Name="ContentGrid" Grid.Row="2"> <ListBox x:Name="lbFeed" ItemsSource="{Binding Items}" SelectionChanged="lbFeed_SelectionChanged" VerticalAlignment="Top" Width="480"> <ListBox.ItemTemplate> <DataTemplate x:Key="MyDataTemplate"> <StackPanel Orientation="Vertical" Width="430"> <TextBlock Text="Some text" TextAlignment="Center" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> I can post more code, but I'm still getting my feet wet in XAML and I'm not sure what might be causing this. If you need more context, let me know and I'll add it here.

  • Is it possible to include a Sexpr before the expression has been evaluated in Sweave / R ?

    - by PaulHurleyuk
    Hello, I'm writing a Sweave document, and I want to include a small section that details the R and package versions, platofrms and how long ti took to evalute the doucment, however, I want to put this in the middle of the document ! I was using a \Sexpr{elapsed} to do this (which didn't work), but thought if I put the code printing elapsed in a chunk that evaluates at the end, I could then include the chunk half way through, which also fails. My document looks something like this % \documentclass[a4paper]{article} \usepackage[OT1]{fontenc} \usepackage{longtable} \usepackage{geometry} \usepackage{Sweave} \geometry{left=1.25in, right=1.25in, top=1in, bottom=1in} \begin{document} <<label=start, echo=FALSE, include=FALSE>>= startt<-proc.time()[3] @ Text and Sweave Code in here % This document was created on \today, with \Sexpr{print(version$version.string)} running on a \Sexpr{print(version$platform)} platform. It took approx sec to process. <<>>= <<elapsed>> @ More text and Sweave code in here <<label=bye, include=FALSE, echo=FALSE>>= odbcCloseAll() endt<-proc.time()[3] elapsedtime<-as.numeric(endt-startt) @ <<label=elapsed, include=FALSE, echo=FALSE>>= print(elapsedtime) @ \end{document} But this doesn't seem to work (amazingly !) Does anyone know how I could do this ? Thanks Paul.

  • How are you supposed to layout a page in VS2010 without using tables?

    - by CrustyApple
    I have been using .NET since beta and HTML since the days of HotDog pro & notepad, using table layout of course. I am FINALLY ready to use only div, li, CSS for the layout, but my question is, what is the proper way to layout pages in VS2010? When i use table layout its simple and i can visually see what im creating and where the elements are, such as the sample below - how should I do this using div's, etc in VS2010? <table width="300" border="0" cellpadding="5"> <tr> <td><img src="http://assets.devx.com/MS_Azure/azuremcau.jpg" alt="blah" width="70" height="70" /></td> <td><h2>This is some text to the right of the picture...</h2></td> </tr> <tr> <td colspan="2">Here some text underneath</td> </tr> </table>

  • removing phone number from a document.

    - by Grant Collins
    Hi, I've got a challenge that I am hoping that the SO community is able to help me with. I trying to parse a lot of html documents in my PHP application to remove personal details, such as names, addresses and phone numbers. I can remove most of these details without too much trouble, however the phone number is a real problem for me. My idea is to take the text from these documents and the use a regex to identify the phone numbers and replace them with another value such as 'xxxx'. I've got 2 regex that I am using one for UK landline numbers and one for UK cell/mobile numbers. However when I try and run them against the text it just returns an empty string. I am using the following preg_replace code: $pattens = array( '/^(((\+44\s?\d{4}|\(?0\d{4}\)?)\s?\d{3}\s?\d{3})|((\+44\s?\d{3}|\(?0\d{3}\)?)\s?\d{3}\s?\d{4})|((\+44\s?\d{2}|\(?0\d{2}\)?)\s?\d{4}\s?\d{4}))(\s?\#(\d{4}|\d{3}))?$/', '/^(\+44\s?7\d{3}|\(?07\d{3}\)?)\s?\d{3}\s?\d{3}$/' ); $replace = array('xxxxx', 'xxxxx'); //do the search for the numbers. $updatedContents = preg_replace($pattens, $replace, $htmlContents); At the moment this is causing me a lot of head scratching as I thought that I had this nailed, but at the moment I can't see what's wrong?? I am sure that it is something really simple. Thanks, Grant

  • Converting contents of a byte array to wchar_t*

    - by Christopher MacKinnon
    I seem to be having an issue converting a byte array (containing the text from a word document) to a LPTSTR (wchar_t *) object. Every time the code executes, I am getting a bunch of unwanted Unicode characters returned. I figure it is because I am not making the proper calls somewhere, or not using the variables properly, but not quite sure how to approach this. Hopefully someone here can guide me in the right direction. The first thing that happens in we call into C# code to open up Microsoft Word and convert the text in the document into a byte array. byte document __gc[]; document = word->ConvertToArray(filename); The contents of document are as follows: {84, 101, 115, 116, 32, 68, 111, 99, 117, 109, 101, 110, 116, 13, 10} Which ends up being the following string: "Test Document". Our next step is to allocate the memory to store the byte array into a LPTSTR variable, byte __pin * value; value = &document[0]; LPTSTR image; image = (LPTSTR)malloc( document->Length + 1 ); Once we execute the line where we start allocating the memory, our image variable gets filled with a bunch of unwanted Unicode characters: ????????????????? And then we do a memcpy to transfer over all of the data memcpy(image,value,document->Length); Which just causes more unwanted Unicode characters to appear: ????????????????? I figure the issue that we are having is either related to how we are storing the values in the byte array, or possibly when we are copying the data from the byte array to the LPTSTR variable. Any help with explaining what I'm doing wrong, or anything to point me in the right direction will be greatly appreciated.

  • Opening a xul file in response to a toolbar extension button click

    - by Graham
    I'm currently building my first Firefox extension, and am having a little difficulty with one piece of functionality. I'd like to open a new browser tab in response to a button click on the toolbar. The new tab should contain the contents of a webpage, together with some extra buttons. At the moment I've created a separate xul file for the contents of the new tab: <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window id="myapp-report-window" title="Example 4.5.1" xmlns:html="http://www.w3.org/1999/xhtml" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://myapp/content/main.js" /> <toolbox> <toolbar id="nav-toolbar"> <toolbarbutton label="This-is-going-to-do-some-stuff"/> </toolbar> </toolbox> <iframe id="myapp-report-frame" flex="1"/> <script type="text/javascript"> function loadPage(url){ document.getElementById('myapp-report-frame').setAttribute('src',url); } </script> </window> This xul file is launched via this javascript, referenced from the main myapptoolbar.xul: gBrowser.selectedTab = gBrowser.addTab('chrome://myapp/content/report.xul'); var newTabBrowser = gBrowser.getBrowserForTab(gBrowser.selectedTab); newTabBrowser.addEventListener("load", function(){ loadPage('http://www.somedynamicallysetwebsite.com'); }, true); The problem that I'm having is that the loadPage function is not being found, so the src attribute of the iframe is never set. I'm sure it's some silly scoping problem, but I'm very new to firefox extensions (day 2!) so any help would be much appreciated. Thanks for looking! Graham

  • Shuffling words in a sentence in javascript (coding horror - How to improve?)

    - by Bill Zimmerman
    Hi, I'm trying to do something that is fairly simple, but my code looks terrible and I am certain there is a better way to do things in javascript. I am new to javascript, and am trying to improve my coding. This just feels very messy. All I want to do is to randomly change the order some words on a web page. In python, the code would look something like this: s = 'THis is a sentence' shuffledSentence = random.shuffle(s.split(' ')).join(' ') However, this is the monstrosity I've managed to produce in javascript //need custom sorting function because javascript doesn't have shuffle? function mySort(a,b) { return a.sortValue - b.sortValue; } function scrambleWords() { var content = $.trim($(this).contents().text()); splitContent = content.split(' '); //need to create a temporary array of objects to make sorting easier var tempArray = new Array(splitContent.length); for (var i = 0; i < splitContent.length; i++) { //create an object that can be assigned a random number for sorting var tmpObj = new Object(); tmpObj.sortValue = Math.random(); tmpObj.string = splitContent[i]; tempArray[i] = tmpObj; } tempArray.sort(mySort); //copy the strings back to the original array for (i = 0; i < splitContent.length; i++) { splitContent[i] = tempArray[i].string; } content = splitContent.join(' '); //the result $(this).text(content); } Can you help me to simplify things?

  • show image in a CGContextRef

    - by Ishu
    What i am doing, i downloded a code from calender now i want to show images on its tiles(for date). What i am trying shows in code - (void)drawTextInContext:(CGContextRef)ctx { CGContextSaveGState(ctx); CGFloat width = self.bounds.size.width; CGFloat height = self.bounds.size.height; CGFloat numberFontSize = floorf(0.3f * width); CGContextSetFillColorWithColor(ctx, kDarkCharcoalColor); CGContextSetTextDrawingMode(ctx, kCGTextClip); for (NSInteger i = 0; i < [self.text length]; i++) { NSString *letter = [self.text substringWithRange:NSMakeRange(i, 1)]; CGSize letterSize = [letter sizeWithFont:[UIFont boldSystemFontOfSize:numberFontSize]]; CGContextSaveGState(ctx); // I will need to undo this clip after the letter's gradient has been drawn [letter drawAtPoint:CGPointMake(4.0f+(letterSize.width*i), 0.0f) withFont:[UIFont boldSystemFontOfSize:numberFontSize]]; if ([self.date isToday]) { CGContextSetFillColorWithColor(ctx, kWhiteColor); CGContextFillRect(ctx, self.bounds); } else { // CGContextDrawLinearGradient(ctx, TextFillGradient, CGPointMake(0,0), CGPointMake(0, height/3), kCGGradientDrawsAfterEndLocation); CGDataProviderRef dataProvider = CGDataProviderCreateWithFilename("left-arrow.png"); CGImageRef image = CGImageCreateWithPNGDataProvider(dataProvider, NULL, NO, kCGRenderingIntentDefault); //UIImage* image = [UIImage imageNamed:@"left-arrow.png"]; //CGImageRef imageRef = image.CGImage; CGContextDrawImage(ctx, CGRectMake(8.0f+(letterSize.width*i), 0.0f, 5, 5), image); //im.image=[UIImage imageNamed:@"left-arrow.png"]; } CGContextRestoreGState(ctx); // get rid of the clip for the current letter } CGContextRestoreGState(ctx); } In else condition i want to show images on the tile so for that i am converting image objects in the CGContextDrawImage. Please help me. I am not sure this would be done in same manner or in other manner please suggest your way to do this. Thanx a lot.
