• IE6 ignoring active link CSS style

  - by Leah

  The CSS active link style is being correctly applied in IE7, FF, and Safari but is not applied IE6. .side_nav a.active { color:#FFFFFF; background-color:#9F1F63; } Interestingly the background color (background-color:#9F1F63;) is being applied in IE6 but not the font color (color:#FFFFFF;) Any ideas on why this is happening and how I can fix it appreciated. The complete styling for the nav below: .side_nav { text-align : left; margin-left: -10px; } .side_nav ul { list-style-type: none; list-style-position:inside; margin-left:0px; } .side_nav li { margin-top: 10px; display: list-item; list-style-type:none; } .side_nav a, .side_nav a:visited { text-decoration: none; color : #9F1F63; font-weight : bold; padding: 5px 10px 5px 10px; } .side_nav a:hover { color:#B26D7F; } .side_nav a.active { color:#FFFFFF; background-color:#9F1F63; } EDIT: Thanks but the suggestions haven't helped. When I change to a:active the active effect does not work in any browser. I think this might be due to how I have applied the style in the HTML. <div class="side_nav"> <a class="active" href="Page1.aspx">Page1</a><br /> <a href="Page2.aspx">Page2</a><br /> <a href="Page3.aspx">Page3</a><br /> </div>

• My jQuery and PHP give different results on the same thing?

  - by Stefan

  Hey all, Annoying brain numbing problem. I have two functions to check the length of a string (primarily, the js one truncates as well) heres the one in Javascript: $('textarea#itemdescription').keyup(function() { var charLength = $(this).val().length; // Displays count $('span#charCount').css({'color':'#666'}); $('span#charCount').html(255 - charLength); if($(this).val().length >= 240){ $('span#charCount').css({'color':'#FF0000'}); } // Alerts when 250 characters is reached if($(this).val().length >= 255){ $('span#charCount').css({'color':'#FF0000'}); $('span#charCount').html('<strong>0</strong>'); var text = $('textarea#itemdescription').val().substring(0,255) $('textarea#itemdescription').val(text); } }); And here is my PHP to double check: if(strlen($_POST["description"])>255){ echo "Description must be less than ".strlen($_POST["description"])." characters"; exit(); } I'm using jQuery Ajax to post the values from the textarea. However my php validation says the strlen() is longer than my js is essentially saying. So for example if i type a solid string and it says 0 or 3 chars left till 255. I then click save and the php gives me the length as being 261. Any ideas? Is it to do with special characters, bit sizes that js reads differently or misses out? Or is it to do with something else? Maybe its ill today!... :P Thanks, Stefan

• sizer.replace() paints "over" old sizercontent

  - by elbenfreund

  hi. I am rather new to wx/python so please excuse if this is stupid or ill described. I am substituting a nested sizer with a new one as shown in the snippet below. after some tinkering everything seems to work out but the re-drawing of the parent-sizer. the content of the old nested sizer remains and gets "painted" over with the new sizer content despite my sizer.Layout() system setup: - python 2.5.5.2 and 2.6.4 - wxpython 2.8 -- coding: utf8 -- import wx class Frame(wx.Frame): def init(self): wx.Frame.init(self, None, wx.ID_ANY, title='test') class Test(wx.App): def OnInit(self): frame = Frame() self.panel = wx.Panel(frame) self.panel.SetBackgroundColour('red') self.sizer = wx.BoxSizer(wx.VERTICAL) button = wx.Button(self.panel, wx.ID_ANY, 'TEST') self.hsizer = wx.BoxSizer(wx.HORIZONTAL) self.hsizer.Add(wx.StaticText(self.panel, wx.ID_ANY, 'nacknack')) self.sizer.Add(button) self.Bind(wx.EVT_BUTTON, self.on_test_button, button) self.text = wx.StaticText(self.panel, wx.ID_ANY, 'FOOO') self.sizer.Add(self.text) self.sizer.Add(self.hsizer) self.panel.SetSizer(self.sizer) frame.Show() return True def on_test_button(self, evt): tmpsizer = wx.BoxSizer(wx.VERTICAL) tmpsizer.Add(self.makesizer()) tmpitem = tmpsizer.GetChildren()[0] self.sizer.Replace(2, tmpitem) self.sizer.Layout() def makesizer(self): testsizer = wx.BoxSizer(wx.HORIZONTAL) testsizer.Add(wx.StaticText(self.panel, wx.ID_ANY, 'testsizer')) return testsizer if __name__ == '__main__': app = Test() app.MainLoop()

• Script tag in ASPX page is written partially (output stopped at random)

  - by Nir

  I have an aspx page where I put a script tag with .net "if" and "else". The problem is that the output gets cut at random points each time. Sometimes it's ok, sometimes I get cropped output. The code itself (Simplified example): <body id="body" runat="server"> <form id="form1" runat="server">some HTML <script type="text/javascript"> window.addEvent('domready', function() { var x = "nothing"; <% if(someCondition){%> x = "2"; <%} else {%> x = "3"; <%}%> }); </script> </form> </body> The cropped output: <body id="body" runat="server"> <form id="form1" runat="server">some HTML <script type="text/javascript"> window.addEvent('domready', function() { var x = "nothi </script> </form> </body> Does anybody have a clue?

• Determine image src in onload and onerror event handlers in IE

  - by Bill

  How can I determine the image src of the image that triggered the event in the onload and onerror event handlers in IE? This example code I threw together: <script language="javascript" type="text/javascript" src="jquery.js"></script> <script language="javascript" type="text/javascript"> function loadImages() { var goodImage = new Image(); var missingImage = new Image(); $(goodImage).bind('load', function(event){ $("#log").append( $(event.target).attr('src') + ' WAS FOUND <br>'); }); $(missingImage).bind('load', function(event){ $("#log").append( $(event.target).attr('src') + ' WAS FOUND <br>' ); }); $(goodImage).bind('error', function(event){ $("#log").append( $(event.target).attr('src') + ' IS MISSING <br>'); }); $(missingImage).bind('error', function(event){ $("#log").append( $(event.target).attr('src') + ' IS MISSING <br>'); }); goodImage.src = 'GOOD-IMAGE.GIF'; // this image exists missingImage.src = 'MISSING-IMAGE.GIF'; // this image doesn't exist } </script> </head> <body onload="loadImages();"> <div id="log"></div> works in FF but in IE8 it prints out undefined for the $(event.target).attr('src') part. I thought jQuery was supposed to normalize the event object for IE so that it acted like other browsers? I've tried a number of permutations but haven't been able to get anything to work in IE8. Anyway if anyone has a suggestion on how to figure out the image src in the onload and onerror event handlers that works in IE I would really appreciate it. Or even how to figure out after the images have loaded which have loaded and which haven't (but not graphically - I need to generate an array containing the filenames of the images that didn't load). Thanks!

• This pagination script is doodoo - I need a better one!

  - by ClarkSKent

  Hello, I was looking at the pagination script (posted below) and found it to be gros,s and not very good at all especially when trying to customize it. This is what the main page looks like: <?php include('config.php'); $per_page = 9; //Calculating no of pages $sql = "select * from messages"; $result = mysql_query($sql); $count = mysql_num_rows($result); $pages = ceil($count/$per_page) ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/ libs/jquery/1.3.0/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" ></div> <ul id="pagination"> <?php //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li id="'.$i.'">'.$i.'</li>'; } ?> </ul> The top part of the code gets the results from the mysql db and than uses this information to display the numbers in the body of this page. I am trying to put something like this on a separate page like count_page.php and then just include it. I guess my question is, if there is a better way of doing the above with better structure. A better way to go through the db and count the results and display the appropriate numbers. The above seems messy. Thanks for any help or suggestions on this.

• Extract the vb code associated with a macro attached to an Action button in PowerPoint

  - by Patricker

  I have about 25 PowerPoint presentations, each with at least 45 slides. On each slide is a question with four possible answers and a help button which provides a hint relevant to the question. Each of the answers and the help button is a PowerPoint Action button that launches a macro. I am attempting to migrate all the questions/answers/hints into a SQL Database. I've worked with Office.Interop before when working with Excel and Word and I have plenty of SQL DB experience, so I don't foresee any issues with actually extracting the text portion of the question and answer and putting it into the db. What I have no idea how to do is given an object on a slide - get the action button info - Get the macro name - and finally get the macro's vb code. From there I can figure out how to parse out which is the correct answer and what the text of the hint is. Any help/ideas would be greatly appreciated. The guy I'm doing this for said he is willing to do it by hand... but that would take a while.

• Android: Why my user Interface does not get drawn when I Inflate the resource layout file?

  - by Einiosaurus

  First of all, I'm a newbie on Android programming, so please be detailed in your answers. I have a layout main.xml file with format similar to <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "vertical" android:layout_width = "fill_parent" android:layout_height = "fill_parent"> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "horizontal"   android:layout_width = "fill_parent" android:layout_height = "fill_parent"> <EditText android:id="@+id/a" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/xSquared" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:text = "@string/equationPart1" /> </LinearLayout> <LinearLayout ... </LinearLayout> </LinearLayout> In my Java source file, I inflate the UI using command: setContentView(R.layout.main); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } However, when I run the emulator, the UI does not show up like what I expect. Instead, it just display a simple EditText text box. I wonder what is going wrong. Is it because I put a layout inside another layout? I don't think there is any problem with that right?

• Where is the "ListViewItemPlaceholderBackgroundThemeBrush" located?

  - by Dimi Toulakis

  I have a problem understanding one style definition in Windows 8 metro apps. When you create a metro style application with VS, there is also a folder named Common created. Inside this folder there is file called StandardStyles.xaml Now the following snippet is from this file: <!-- Grid-appropriate 250 pixel square item template as seen in the GroupedItemsPage and ItemsPage --> <DataTemplate x:Key="Standard250x250ItemTemplate"> <Grid HorizontalAlignment="Left" Width="250" Height="250"> <Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}"> <Image Source="{Binding Image}" Stretch="UniformToFill"/> </Border> <StackPanel VerticalAlignment="Bottom" Background="{StaticResource ListViewItemOverlayBackgroundThemeBrush}"> <TextBlock Text="{Binding Title}" Foreground="{StaticResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextStyle}" Height="60" Margin="15,0,15,0"/> <TextBlock Text="{Binding Subtitle}" Foreground="{StaticResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource CaptionTextStyle}" TextWrapping="NoWrap" Margin="15,0,15,10"/> </StackPanel> </Grid> </DataTemplate> What I do not understand here is the static resource definition, e.g. for the Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" It is not about how you work with templates and binding and resources. Where is this ListViewItemPlaceholderBackgroundThemeBrush located? Many thanks for your help. Dimi

• Can a page opt out of IIS 7 compression?

  - by Glen Little

  My pages are automatically being compressed by IIS7 with GZIP. That is great... but, for one particular page, I need to stream it to the user, using Response.Flush() when needed. But when the output is being compressed, the IIS server seems to collect all my output until the page is done before compressing and sending it to the client. That nullifies my attempt to Flush the content out to the user. Is there a way that I can have this one page opt out of the compression? One possible option I've determined that if I manually set the content type to one that does not match the IIS configuration at c:\windows\system32\inetsrv\config\applicationhost.config, then IIS will not compress it. Eg. Response.ContentType = "x-text/html". This works okay with IE8, as it falls back to display the HTML. But Firefox will ask the user what to do with the unknown file type. This could work, if there was another Mime Type I could use that browsers would accept as HTML, that is not matched in the applicationhost.config. For reference, these are the mime types that will be compressed: <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> Others options? Are there other options to opt out of compression?

• C system calls open / read / write / close problem.

  - by Andrei Ciobanu

  Hello, given the following code (it's supposed to write "hellowolrd" in a "helloworld" file, and then read the text): #include <fcntl.h> #include <sys/types.h> #include <sys/stat.h> #define FNAME "helloworld" int main(){ int filedes, nbytes; char buf[128]; /* Creates a file */ if((filedes=open(FNAME, O_CREAT | O_EXCL | O_WRONLY | O_APPEND, S_IRUSR | S_IWUSR)) == -1){ write(2, "Error1\n", 7); } /* Writes hellow world to file */ if(write(filedes, FNAME, 10) != 10) write(2, "Error2\n", 7); /* Close file */ close(filedes); if((filedes = open(FNAME, O_RDONLY))==-1) write(2, "Error3\n", 7); /* Prints file contents on screen */ if((nbytes=read(filedes, buf, 128)) == -1) write(2, "Error4\n", 7); if(write(1, buf, nbytes) != nbytes) write(2, "Error5\n", 7); /* Close rile afte read */ close(filedes); return (0); } The first time i run the program, the output is: helloworld After that every time I to run the program, the output is: Error1 Error2 helloworld I don't understand why the text isn't appended, as I've specified the O_APPEND file. Is it because I've included O_CREAT ? It the file is already created, shouldn't O_CREAT be ignored ?

• css: make background repeat-y with growing child content?

  - by mikemikemike

  I Have a three column layout. The center div is a container which holds all of my content. The outer columns is just a .png that fades into the body's background (left and right respectively). I want the .png to repeat-y to grow with the center container's content. It will only print the image once, and ignores the repeat-y. If I specify a height to the outside columns, it will print, but only to the specified height. I tried height: 100%, which does not work. Here is my code: #ultra_contain { text-align:left; width:900px; padding: 0px; position:relative; margin:0px auto; margin-top:0px; /*border:1px dashed #996;*/ } #gradientleft { float:left; position:relative; background: url("../i/gradient_left.png") repeat-y; /*border:1px dashed #996;*/ } #gradientright { float:right; position:relative; background: url("../i/gradient_right.png") repeat-y; /*border:1px dashed #996;*/ } #container { text-align:left; width:700px; position:relative; margin:5px auto; margin-top:0px; background:#fff; /*border:1px dashed #996;*/ }

• Sending buffered images between Java client and Twisted Python socket server

  - by PattimusPrime

  I have a server-side function that draws an image with the Python Imaging Library. The Java client requests an image, which is returned via socket and converted to a BufferedImage. I prefix the data with the size of the image to be sent, followed by a CR. I then read this number of bytes from the socket input stream and attempt to use ImageIO to convert to a BufferedImage. In abbreviated code for the client: public String writeAndReadSocket(String request) { // Write text to the socket BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())); bufferedWriter.write(request); bufferedWriter.flush(); // Read text from the socket BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(socket.getInputStream())); // Read the prefixed size int size = Integer.parseInt(bufferedReader.readLine()); // Get that many bytes from the stream char[] buf = new char[size]; bufferedReader.read(buf, 0, size); return new String(buf); } public BufferedImage stringToBufferedImage(String imageBytes) { return ImageIO.read(new ByteArrayInputStream(s.getBytes())); } and the server: # Twisted server code here # The analog of the following method is called with the proper client # request and the result is written to the socket. def worker_thread(): img = draw_function() buf = StringIO.StringIO() img.save(buf, format="PNG") img_string = buf.getvalue() return "%i\r%s" % (sys.getsizeof(img_string), img_string) This works for sending and receiving Strings, but image conversion (usually) fails. I'm trying to understand why the images are not being read properly. My best guess is that the client is not reading the proper number of bytes, but I honestly don't know why that would be the case. Side notes: I realize that the char[]-to-String-to-bytes-to-BufferedImage Java logic is roundabout, but reading the bytestream directly produces the same errors. I have a version of this working where the client socket isn't persistent, ie. the request is processed and the connection is dropped. That version works fine, as I don't need to care about the image size, but I want to learn why the proposed approach doesn't work.

• Editing a remote file on-the-fly with PHP

  - by user275074

  Hi, I have a requirement to edit a remote text file on-the-fly, the content of which currently stands at ~1Mb. I have tried a couple of approaches and both seem to be clunky or hog memory which I can't rely on. Thinking out logically what I'm trying to achieve is: FTP to a remote server. Download a copy of the file for backup purposes and store it somewhere locally. Open the remote file and add the necessary lines required. Remove lines from the remote file as per an array of un-required data generated from the local server. Is this possible? I've managed to code steps 1 and 2 but I'm having difficult with 3 and 4. The way I'm doing it now is to use fgets and return the whole string. Really, I don't want to do this as it involves manipulating and re-generating the whole string (and it's large) and then re-inserting it in between two markers in the remote file. Is there no way of manipulating the lines of text in the file on-the-fly?

• How to use AJAX to populate state list depending on Country list?

• Font advance calculation problem on Blackberry OS 5.0

  - by John

  I am currently working on my own implementation of a tab bar for a BlackBerry app, where each tab bar has a title that is right aligned (i.e. the last character in each should be the same distance from the right hand side of the screen). To work out where to draw the text I am using the following calculation: screen width - advance of title - indent. The font I am using is 'BBAlpha Sans' (height 28). Using BlackBerry OS 4.6 everything seems to be calculated properly and the text is aligned when I move between tabs, however I am finding that when I use OS 5.0 it doesn't calculate the advance properly and as a result the alignment is off by maybe 5 pixels or so. With the default font (also BBAlpha Sans, but height 24 - for OS 5.0 at least) it works fine in both versions.. but I don't necessarily always want to use the default font/size, so any ideas what could be going wrong? Is this a bug in the 5.0 API? Thanks. Code: public class TitleBarBackground extends Background { .. public void draw(Graphics graphics, XYRect rect) { graphics.pushRegion(rect); .. Font titleBarFont = FontFamily.forName("BBAlpha Sans").getFont(Font.PLAIN, 28); ... int textWidth = titleBarFont.getAdvance(title); graphics.drawText(title, rect.width - textWidth - TITLE_OFFSET, textYOffset); graphics.popContext(); } .. }

• Word wrap in multiline textbox after 35 characters

  - by Kanavi

  <asp:TextBox CssClass="txt" ID="TextBox1" runat="server" onkeyup="CountChars(this);" Rows="20" Columns="35" TextMode="MultiLine" Wrap="true"> </asp:TextBox> I need to implement word-wrapping in a multi-line textbox. I cannot allow users to write more then 35 chars a line. I am using the following code, which breaks at precisely the specified character on every line, cutting words in half. Can we fix this so that if there's not enough space left for a word on the current line, we move the whole word to the next line? function CountChars(ID) { var IntermediateText = ''; var FinalText = ''; var SubText = ''; var text = document.getElementById(ID.id).value; var lines = text.split("\n"); for (var i = 0; i < lines.length; i++) { IntermediateText = lines[i]; if (IntermediateText.length <= 50) { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } else { while (IntermediateText.length > 50) { SubText = IntermediateText.substring(0, 50); FinalText += SubText + "\n"; IntermediateText = IntermediateText.replace(SubText, ''); } if (IntermediateText != '') { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } } } document.getElementById(ID.id).value = FinalText; $('#' + ID.id).scrollTop($('#' + ID.id)[0].scrollHeight); } Edit - 1 I have to show total max 35 characters in line without specific word break and need to keep margin of two characters from the right. Again, the restriction should be for 35 characters but need space for total 37 (Just for the Visibility issue.)

• 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!

  - by jimpsr

  The app I am working on requires dynamic loading of css and js, right now the solution is as follows: myapp.loadCss = function(css){ $("head").append("<link>"); cssDom = $("head").children(":last"); cssDom.attr({rel: "stylesheet", type: "text/css", href: css }); } myapp.loadJs = funciton(js){ ... //$.ajax call is used in synchronized mode to make sure the js is fully loaded } } When some widgets need to be load, the usual call with be myapp.loadCss('/widgets/widget1/css/example.css'); myapp.loadJs('/wiggets/widget1/js/example.js'); The weired thing is that once a while (1 out of 10 or 20), the newly created dom elements from example.js will not be able to get its css from example.css, it seems however my loadCss method does not load the css in a synchronized mode? I have tried to replace my loadCss with the the following code: myapp.loadCss(css){ $('<link href="' + css + '" rel="stylesheet" type="text/css" />').appendTo($('head')); } It seems to be OK then (I refreshed the webpage a hundred times for verification :-( ) But unfortunately this method failed in IE(IE7, not tested in IE6, 8) Is there any better solution for this?

• Saving NSString to file

  - by Michael Amici

  I am having trouble saving simple website data to file. I believe the sintax is correct, could someone help me? When I run it, it shows that it gets the data, but when i quit and open up the file that it is supposed to save to, nothing is in it. - (BOOL)textFieldShouldReturn:(UITextField *)nextField { [timer invalidate]; startButton.hidden = NO; startButton.enabled = YES; stopButton.enabled = NO; stopButton.hidden = YES; stopLabel.hidden = YES; label.hidden = NO; label.text = @"Press to Activate"; [nextField resignFirstResponder]; NSString *urlString = textField.text; NSData *dataNew = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]]; NSUInteger len = [dataNew length]; NSString *stringCompare = [NSString stringWithFormat:@"%i", len]; NSLog(@"%@", stringCompare); NSString *filePath = [[NSBundle mainBundle] pathForResource:@"websiteone" ofType:@"txt"]; if (filePath) { [stringCompare writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:NULL]; NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL]; NSLog(@"Saving... %@", myText); } else { NSLog(@"cant find the file"); } return YES; }

• Combining the jquery Calendar picker with the jquery validation and getting them to play nice?

  - by MBonig

  I'm just starting to get into jquery/javascript programming so this may be a beginner question but I sure can't seem to find anything about it. I have a text field on a form. I've used the JQuery UI Calendar picker to make data entry better. I've also added jquery validation to ensure that if the user enters the date by hand that it's still valid. Here is the html: <input class="datepicker" id="Log_ServiceStartTime_date" name="Log_ServiceStartTime_date" type="text" value="3/16/2010"></input> and javascript: $('form').validate(); $('#Log_ServiceStartTime_date').rules('add','required'); $('#Log_ServiceStartTime_date').rules('add','date'); the problem I'm having is this: If a user puts in a bad date, or no date at all, the validation correctly kicks in and the error description displays. However, if the user clicks on the textbox to bring up the calendar picker and selects a date, the date fills into the field but the validation does not go away. If the user clicks into the textbox and then back out, the validation correctly goes away. How can I get the calendar picker to kick off the validation routine once a date is selected? thanks

• Debugging Post Request with Chrome Dev Tools

  - by benek

  I am trying to use Chrome Dev for debugging the following Angular post request : $http.post("http://picjboss.puma.lan:8880/fluxpousse/api/flow/createOrUpdateHeader", flowHeader) After running the statement with right-click / evaluate, I can see the post in the network panel with a pending state. How can I get the result or "commit" the request and leave easily this "pending" state from the dev console ? I am not yet very familiar with JS callbacks, some code is expected. Thanks. EDIT I have tried to run from the console : $scope.$apply(function(){$http.post("http://picjboss.puma.lan:8880/fluxpousse/api/flow/createOrUpdateHeader", flowHeader).success(function(data){console.log("error "+data)}).error(function(data){console.log("error "+data)})}) It returns : undefined EDIT The post I am trying to solve generate an HTTP 400.

• How to let one external stylsheet selectively overrule the other

  - by Ferdy

  I'm stunned by a simple thing that I want to accomplish but does not work. I have a website and I want it to support themes, which are a named set of CSS + images. No matter which theme is selected, I always include the main CSS file, which is the default theme. On top of that I'm loading a second stylesheet, the one that is theme-specific, like so: <link rel="stylesheet" type="text/css" href="css/main.css" title=main" media="screen" /> <link rel="stylesheet" type="text/css" href="themes/<?= $style ?>/css/<?= $style ?>.css" title="<?= $style ?>" media="screen" /> My idea is that the theme specific css should not be a full copy of the main css file. Instead, it should only contain CSS rules that overrule those of the main.css file. This makes themes much smaller and easier to maintain. I thought I could simply load two external stylesheets after each other and that for conflicting rules it will always use the theme specific css, the second file. However, it does not seem to work. If I make a dramatic styling change in the theme file then it has no effect. If I then comment the main CSS file, the theme CSS does have effect. Was I too naive in expecting this to work like this? I know I can use inline styles to overrule anything, but I prefer a setup like this if possible.
