  • jquery insertAfter or append question

    - by user271619
    I am playing around with validating form inputs. For now I'm simply having fun with displaying a message after the input. I'm using the after() method to display simple text, and when I purposely make a mistake in the box I display the message perfectly. However, if I purposely make a mistake again, it immediately adds the same message after the first error message. Is there a method that replaces the original? I didn't want to try to add some more code to look for that original error message, delete it, and then insert the same message again. I will if I have to, but I thought I'd ask first. Here's my code: <script language="javascript" type="text/javascript"> $(document).ready(function(){ $("form#testform").submit(function(){ if($("#fieldname1").val().length < 5){ $("#fieldone").after("<div>not enough characters</div>"); } });return false; }); </script> <form id="testform" method="post"> <table> <tr> <td style="width:100px;">Field One:</td> <td><input type="text" name="fieldname1" id="fieldname1" /></td> </tr> <tr> <td>&nbsp;</td> <td><input type="submit" name="Submit" value="Submit" /></td> </tr> </table> </form>

  • naive bayesian spam filter question

    - by Microkernel
    Hi guys, I am planning to implement spam filter using Naive Bayesian classification model. Online I see a lot of info on Naive Bayesian classification, but the problem is its a lot of mathematical stuff, than clearly stating how its done. And the problem is I am more of a programmer than a mathematician (yes I had learnt Probability and Bayesian theorem back in school, but out of touch for a long long time, and I don't have luxury of learning it now (Have nearly 3 weeks to come-up with a working prototype)). So if someone can explain or point me to location where its explained for programmers than a mathematician, it would be a great help. PS: By the way I have to implement it in C, if you want to know. :( Regards, Microkernel

  • Objective-C (iPhone) Memory Management

    - by Steven
    I'm sorry to ask such a simple question, but it's a specific question I've not been able to find an answer for. I'm not a native objective-c programmer, so I apologise if I use any C# terms! If I define an object in test.h @interface test : something { NSString *_testString; } Then initialise it in test.m -(id)init { _testString = [[NSString alloc] initWithString:@"hello"]; } Then I understand that I would release it in dealloc, as every init should have a release -(void)dealloc { [_testString release]; } However, what I need clarification on is what happens if in init, I use one of the shortcut methods for object creation, do I still release it in dealloc? Doesn't this break the "one release for one init" rule? e.g. -(id)init { _testString = [NSString stringWithString:@"hello"]; } Thanks for your helps, and if this has been answered somewhere else, I apologise!!

  • On Android, click to expand list -and- click on a button?

    - by Aurora
    I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView). In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth. I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

  • Forcing an item to remain in place in a jQuery UI Sortable list

    - by calumbrodie
    I've set up a jQuery sortable list but I need to be able to keep some items in the sortable 'fixed' in place and for the other items to sort around them. I thought that there would be built in methods to achieve this, alas this is not the case. I'm able to set up the list and not include the items in question: <ul id="fruit"> <li class="fixed">apples</li> <li>oranges</li> <li>bananas</li> <li>pineapples</li> <li>grapes</li> <li class="fixed">pears</li> <li>mango</li> </ul> <script type="text/javascript"> $('#fruit').sortable({items: "li:not('.fixed')"}) </script> This stops me from drag/dropping these items but they still move if the items around them are sorted. There may be a way to do this using the many callbacks that this method has but I've been unable to work this out. Maybe this method would be a good addition to the UI Sortable options?

  • How can I make a grid of clickable images from a list of data in WPF?

    - by mico
    Hello, I am a seasoned C and Java programmer, but an absolute WPF newbie. I am creating a kiosk application that will display a list of images of products that the user will click to see product details and maybe place an order. I am trying to structure my app with MVVM Foundation because I am used to the benefits of structure and tests. I wonder what is the most natural way to create a grid of clickable images that will fill the screen left to right, top to bottom (or the other way round, I have no exact requirements). Any image should be bound to an object that will become current and be displayed in the next screen. Thanks for your help.

  • Object.Watch with disabled attribute

    - by Benjamin Fleming
    <html> <head> <script type="text/javascript"> window.onload = function() { var btn = document.getElementById("button"); var tog = document.getElementById("toggle"); tog.onclick = function() { if(btn.disabled) { btn.disabled = false; } else { btn.disabled = true; } }; //btn.watch("disabled", function(prop, val, newval) { }); }; </script> </head> <body> <input type="button" value="Button" id="button" /> <input type="button" value="Toggle" id="toggle" /> </body> </html> If you test this code, the Toggle button will successfully enable and disable the other button. However, un-commenting the btn.watch() line will somehow always set the disabled tag to true. Any ideas?

  • how to escape white space in bash loop list

    - by MCS
    I have a bash shell script that loops through all child directories (but not files) of a certain directory. The problem is that some of the directory names contain spaces. Here are the contents of my test directory: $ls -F test Baltimore/ Cherry Hill/ Edison/ New York City/ Philadelphia/ cities.txt And the code that loops through the directories: for f in `find test/* -type d`; do echo $f done Here's the output: test/Baltimore test/Cherry Hill test/Edison test/New York City test/Philadelphia Cherry Hill and New York City are treated as 2 or 3 separate entries. I tried quoting the filenames, like so: for f in `find test/* -type d | sed -e 's/^/\"/' | sed -e 's/$/\"/'`; do echo $f done but to no avail. There's got to be a simple way to do this. Any ideas? The answers below are great. But to make this more complicated - I don't always want to use the directories listed in my test directory. Sometimes I want to pass in the directory names as command-line parameters instead. I took Charles' suggestion of setting the IFS and came up with the following: dirlist="${@}" ( [[ -z "$dirlist" ]] && dirlist=`find test -mindepth 1 -type d` && IFS=$'\n' for d in $dirlist; do echo $d done ) and this works just fine unless there are spaces in the command line arguments (even if those arguments are quoted). For example, calling the script like this: test.sh "Cherry Hill" "New York City" produces the following output: Cherry Hill New York City Again, I know there must be a way to do this - I just don't know what it is...

  • jQuery AJAX Character Encoding Problem

    - by Salty
    Hi everyone, I'm currently coding a French website. There's a schedule page, where a link on the side can be used to load another day's schedule. http://aquate.us/film/horaire.html (At the moment, only the links for November 13th and November 14th work) Here's the JS I'm using to do this: <script type="text/javascript"> function load(y) { $.get(y,function(d) { $("#replace").html(d); mod(); }); } function mod() { $("#dates a").click(function() { y = $(this).attr("href"); load(y); return false; }); } mod(); </script> The actual AJAX works like a charm. My problem lies with the response to the request. Because it is a French website, there are many accented letters. I'm using the ISO-8859-15 charset for that very reason. However, in the response to my AJAX request, the accents are becoming ?'s because the character encoding seems to be changed back to UTF-8. How do I avoid this? I've already tried adding some PHP at the top of the requested documents to set the character set: <?php header('Content-Type: text/html; charset=ISO-8859-15'); ?> But that doesn't seem to work either. Any thoughts? Also, while any of you are looking here...why does the rightmost column seem to become smaller when a new page is loaded, causing the table to distort and each <li> within the <td> to wrap to the next line? Cheers

  • Synchronizing an ERWin model with a Visual Studio 2008 GDR 2/2010 db project

    - by Grant Back
    I am looking for options to get our vast collection of DB objects across many DBs into source control (TFS 2010). Once we succeed here, we will work toward generating our alter scripts for a particular DB change via TFS build. The problem is, our data architecture group is responsible for maintaining the DB objects (excluding SPs), and they work within a model centric process, via ERWin. What this means, is that they maintain the DBs via ERWin models, and generate alters from them that are used to release changes. In order to achieve our goal of getting the DB objects (not just the ERWin models) into TFS, I believe the best option is to do this via Visual Studio DB projects. From what I can tell, there is very little urgency for CA to continue supporting an integration between ERWin and Visual Studio, that no longer works as of Visual Studio 2008 DB Ed. GDR. If I have been mislead in this regard, please feel free to set me straight. One potential solution is to: Perform changes in the ERWin model. Take the alter script generated from ERWin, and import the script into the appropriate Visual Studio DB project, updating the objects in the in the DB project Check the changed objects in the DB project into TFS. TFS Build executes to generate the alter scripts that will be used to push the changes through our release process. My question is, is this solution viable, or are there any other options?

  • UpdatePanel doesn't do partial-page update, and IsInAsyncPostBack is always false

    - by Joseph Anderson
    I'm attempting to use an UpdatePanel, but can't get partial-page updates to work. When I look at the ScriptManager's IsInAsyncPostBack property, it's always false. Here's a page that reproduces the issue. It has a ScriptManager, an UpdatePanel, a LinkButton within the update panel, and a Button wired up to the UpdatePanel via the Triggers collection. <%@ Page Language="C#" %> <script runat="server"> protected void Page_Load(object sender, EventArgs e) { Label1.Text = DateTime.Now.ToString(); if (IsPostBack) Label1.Text += " - Postback!"; if (ScriptManager1.IsInAsyncPostBack) Label1.Text += " - Async!"; } </script> <html xmlns="http://www.w3.org/1999/xhtml"> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server" /> <asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server"> <ContentTemplate>Panel 1:<asp:Label runat=server ID=Label1 /><br /> <asp:LinkButton runat=server ID="LinkButton1" Text="Update!"></asp:LinkButton></ContentTemplate> <Triggers><asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /></Triggers> </asp:UpdatePanel> <asp:Button ID="Button1" Text="Refresh Panel 1" runat="server" UseSubmitBehavior=false /> </form> </body> </html> If I run this code and click on either of the buttons, I see "Panel 1:2/8/2010 3:38:41 PM - Postback!" I expected that clicking either button would cause a partial-page update for UpdatePanel1, that IsInAsyncPostBack would be true, and that " - Async!" would be appended to Label1. Any idea why IsInAsyncPostBack is always false?

  • Cookies not present after using XMLHttpRequest

    - by Joe B
    I'm trying to make a bookmarklet to download videos off of YouTube, but I've come across a little problem. To detect the highest quality video available, I use a sort of brute force method, in which I make requests using the XMLHttpRequest object until a 404 isn't returned (I can't do it until a 200 ok is returned because YouTube redirects to a different server if the video is available, and the cross-domain policy won't allow me to access any of that data). Once a working URL is found, I simply set window.location to the URL and the download should start, right? Wrong. A request is made, but for reasons unknown to me, the cookies are stripped and YouTube returns a 403 access denied. This does not happen if the XML requests aren't made before it, i.e. if I just set the window.location to the URL everything works fine, it's when I do the XMLHttpRequest that the cookies aren't sent. It's hard to explain so here's the script: var formats = ["37", "22", "35", "34", "18", ""]; var url = "/get_video?video_id=" + yt.getConfig('SWF_ARGS')['video_id'] + "&t=" + (unescape(yt.getConfig('SWF_ARGS')['t'])) + "&fmt="; for (var i = 0; i < formats.length; i++) { xmlhttp = new XMLHttpRequest; xmlhttp.open("HEAD", url + formats[i], false); xmlhttp.send(null); if (xmlhttp.status != 404) { document.location = url + formats[i]; break } } That script does not send the cookies after setting the document.location and thus does not work. However, simply doing this: document.location = /get_video?video_id=" + yt.getConfig('SWF_ARGS')['video_id'] + "&t=" + (unescape(yt.getConfig('SWF_ARGS')['t'])) DOES send the cookies along with the request, and does work. The only downside is I can't automatically detect the highest quality, I just have to try every "fmt" parameter manually until I get it right. So my question is: why is the XMLHttpRequest object removing cookies from subsequent requests? This is the first time I've ever done anything in JS by the way, so please, go easy on me. ;)

  • About function scopes in javascript

    - by Shawn
    Look at the code below. I want to alert the value of i at the moment that specific listener was added. Is other words, clicking each marker should alert a different value. Where can I store the value of i in a way that it won't change and be accessible inside the scope of that function? Here is problematic code: (it is difficult to test because you need a key from Google) <html> <head> <title>a</title> <script type="text/javascript"> function init() { map = new GMap2(document.getElementById("map_canvas")); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMap2 map.setCenter(new GLatLng(0, 0), 1); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMap2.setCenter for(var i = 0; i < 10; i++) { var marker = new GMarker(point); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMarker map.addOverlay(marker); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMap2.addOverlay GEvent.addListener(marker, "click", function() // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GEvent.addListener { alert(i); // Problem: I want the value of i at the moment when the listener is added. }); } } window.onload = init; </script> </head> <body id="map_canvas"> </body> </html> Thanks!

  • Issues with cross-domain uploading

    - by meder
    I'm using a django plugin called django-filebrowser which utilizes uploadify. The issue I'm having is that I'm hosting uploadify.swf on a remote static media server, whereas my admin area is on my django server. At first, the browse button wouldn't invoke my browser's upload. I fixed this by modifying the sameScriptAccess to always instead of sameDomain. Now the progress bar doesn't move at all, I probably have to enable some server setting for cross domain file uploading, or most likely actually host a separate upload script on my media server. I thought I could solve this by adding a crossdomain.xml to enable any site at the root of both servers, but that doesn't seem to solve it. $(document).ready(function() { $('#id_file').uploadify({ 'uploader' : 'http://media.site.com:8080/admin/filebrowser/uploadify/uploadify.swf', 'script' : '/admin/filebrowser/upload_file/', 'scriptData' : {'session_key': '...'}, 'checkScript' : '/admin/filebrowser/check_file/', 'cancelImg' : 'http://media.site.com:8080/admin/filebrowser/uploadify/cancel.png', 'auto' : false, 'folder' : '', 'multi' : true, 'fileDesc' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'fileExt' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'sizeLimit' : 10485760, 'scriptAccess' : 'always', //'scriptAccess' : 'sameDomain', 'queueSizeLimit' : 50, 'simUploadLimit' : 1, 'width' : 300, 'height' : 30, 'hideButton' : false, 'wmode' : 'transparent', translations : { browseButton: 'BROWSE', error: 'An Error occured', completed: 'Completed', replaceFile: 'Do you want to replace the file', unitKb: 'KB', unitMb: 'MB' } }); $('input:submit').click(function(){ $('#id_file').uploadifyUpload(); return false; }); }); The page I'm viewing this on is http://site.com/admin/filebrowser/browse on port 80.

  • basic javascript question on geolocation and googlemaps

    - by ade
    hello all, Im hoping that somebody can help me out on what i feel is an easy answer but I just cant get it to work out. Im trying to trap the geolocation lat and long and place it into the google maps api so far i have var myOptions = { zoom:7, trips:1, mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map"), myOptions); directionsDisplay.setMap(map); var request = { origin: 'newyork' destination: 'deleware', travelMode: google.maps.DirectionsTravelMode.DRIVING }; this works fine for what i want. how ever I want to be able to change Origin to the users lat long using the following script from google.maps.api. their code is: if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); var placeMarker = new google.maps.Marker({ position: initialLocation, map: map, }); map.setCenter(initialLocation); }, function() { handleNoGeolocation(browserSupportFlag); }); } else { // Browser doesn't support Geolocation handleNoGeolocation(); } function handleNoGeolocation() { initialLocation = newyork; map.setCenter(initialLocation); } I want to pull out the navigator.geolocation.getCurrentPosition(function(position) { initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); and allocate it two 2 varibles, myLat and myLong. I then want to be able to change my orignal script from var request = { origin: 'newyork' destination: 'deleware', travelMode: google.maps.DirectionsTravelMode.DRIVING }; to var request = { origin: myLat,myLong destination: 'deleware', travelMode: google.maps.DirectionsTravelMode.DRIVING }; Does this make sense..? Im currently having a pig with it and as im not a JS developer its what i think should be a simple bit of coding that im losing the battle with.. any thoughts..?

  • Named pipe blocking with user nobody

    - by dnagirl
    I have 2 short scripts. The first, an awk script, processes a large file and prints to a named pipe 'myfifo.dat'. The second, a Perl script, runs a LOAD DATA LOCAL INFILE 'myfifo.dat'... command. Both of these scripts work when run locally like so: lee.awk big.file & lee.pl However, when I call these scripts from a PHP webpage, the named pipe blocks: $awk="/path/to/lee.awk {$_FILES['uploadfile']['tmp_name']} &"; $sql="/path/to/lee.pl"; if(!exec($awk,$return,$err)) throw new ZException(print_r($err,true)); //blocks here if(!exec($sql,$return,$err)) throw new ZException(print_r($err,true)); If I modify the awk and Perl scripts so that they write and read to a normal file, everything works fine from PHP. The permissions on the fifo and the normal file are 666 (for testing purposes). These operations run much more quickly through a named pipe, so I'd prefer to use one. Any ideas how to unblock it? ps. In case you're wondering why I'm going to all this aggravation, see this SO question.

  • Noob-Ready Cython Tutorials

    - by spearfire
    I know a bunch of scripting languages, (python, ruby, lua, php) but I don't know any compiled languages like C/C++ , I wanted to try and speed up some python code using cython, which is essentially a python - C compiler, aimed at creating C extensions for python. Basically you code in a stricter version of python which compiles into C - native code. here's the problem, I don't know C, yet the cython documentation is aimed at people who obviously already know C (nothing is explained, only presented), and is of no help to me, I need to know if there are any good cython tutorials aimed at python programmers, or if I'm gonna have to learn C before I learn Cython. bear in mind I'm a competent python programmer, i would much rather learn cython from the perspective of the language I'm already good at, rather than learn a whole new language in order to learn cython. 1) PLEASE don't recommend psyco edit: ANY information that will help understand the oficial cython docs is useful information

  • Getting gridview column value as parameter for javascript function

    I have a gridview with certain number of columns and the ID column where I want to get the value from is currently set to visible = false.

I'm having a hard time getting my head wrapped around how to use my defined model relationships. I've tried searching Google, but all I can come up with are basically cheat sheets for what has_many, belongs_to, etc all mean. This stuff is easy to define & understand, especially since I've done a lot of work directly with SQL. What I don't understand is how to actually used those defined relationships. In my case I have 3 models: Locations Hosts Services Relationships (not actual code, just for shortening it): Services belongs_to :hosts Hosts has_many :services belongs_to :locations Locations has_many :hosts In this case I want to be able to display a column from Locations while working with Services. In SQL this is a simple join, but I want to do it the Rails/Ruby way, and also not use SQL in my code or redefine my joins.

  • Compile-time lookup array creation for ANSI-C?

    - by multiproximus
    A previous programmer preferred to generate large lookup tables (arrays of constants) to save runtime CPU cycles rather than calculating values on the fly. He did this by creating custom Visual C++ projects that were unique for each individual lookup table... which generate array files that are then #included into a completely separate ANSI-C micro-controller (Renesas) project. This approach is fine for his original calculation assumptions, but has become tedious when the input parameters need to be modified, requiring me to recompile all of the Visual C++ projects and re-import those files into the ANSI-C project. What I would like to do is port the Visual C++ source directly into the ANSI-C microcontroller project and let the compiler create the array tables. So, my question is: Can ANSI-C compilers compute and generate lookup arrays during compile time? And if so, how should I go about it? Thanks in advance for your help!
