  Hi all i am developing an application which has a general text entry form.

• Possible to add javascript to Zend_Form_Element_Radio?

  - by Stepppo

  Ultimately, I'd like my Zend Form to render this HTML: <p>Do you have any documents to upload?</p> <p>Yes <input type="radio" value="Yes" name="uploadChoice" onClick="showTable()">&nbsp;&nbsp;No <input type="radio" value="No" name="uploadChoice" onClick="hideTable()" checked></p> Here's what I have in my Zend_Form: //create radio buttons $uploadQuestion = new Zend_Form_Element_Radio('upLoadQuestion'); $uploadQuestion->setLabel('Do you have any documents to upload?') ->addMultiOptions(array( 'yes' => 'Yes', 'no' => 'No' )) ->setSeparator(' '); The problem I'm running into is how to add the onClick="showTable()" and onClick="hideTable()" elements to their respective radio buttons. In the alternative, I could rework the javascript and add something like onClick="toggleTable()" to the radio buttons if I can't add something different to each of the radio buttons. But, will Zend let me do that?

• Collect DOM elements from external HTML documents

  - by sonofdelphi

  I am trying to write a report-generator to collect user-comments from a list of external HTML files. User-comments are wrapped in < span elements. Can this be done using JavaScript? Here's my attempt: function generateCommentReport() { var files = document.querySelectorAll('td a'); //Files to scan are links in an HTML table var outputWindow = window.open(); //Output browser window for report for(var i = 0; i<files.length; i++){ //Open each file in a browser window win = window.open(); win.location.href = files[i].href; //Scan opened window for 'comment's comments = win.document.getElementsByName('comment'); for(var j=0;j<comments.length;j++){ //Add to output report outputWindow.document.write(comment[i].innerHTML); } } }

• XQuery fn:replace not behaving as expected

  - by CoolGravatar

  I have an Excel worksheet in XML format which contains <Cell ss:StyleID="s127"><Data ss:Type="String">A01-Replace</Data></Cell> I want to replace @A01-Replace with a different string. I'm using the XQuery's replace function like so: let $excel := doc("excel.xml") let $test := "another string" return replace($excel, "(A[0-9]+-Replace)", $test) Before calling replace, the variable $excel is valid XML upon output. However, when I output $excel after I call the replace function, all of the XML tags have been stripped, and $excel is a string with the content of the cells as its values. I would like to keep the XML tags there. Any ideas?

• Sanitize HTML before storing in the DB or before rendering? (AntiXSS library in ASP.NET)

  - by user102533

  I have an editor that lets users add HTML that is stored in the database and rendered on a web page. Since this is untrusted input, I plan to use Microsoft.Security.Application.AntiXsSS.GetSafeHtmlFragment to sanitize the HTML. Should I santiize before saving to the database or before rendering the untrusted input into the webpage? Is there an advantage in including the AntiXSS source code in my project instead of just the DLL? (Maybe I can customize the white list?) Which class file should I look in for actual implementation of the GetSafeHtmlFragment

How can I take data I need from database and save it to file "at once"? (as quick as possible? I don't need xml output because I can process data from output on my server later. I just need to do it as quickly as possible. Any idea?) Many thanks!

• Understanding The Convolution Matrix

  - by Ryan Naddy

  I am learning about the Convolution Matrix, and I understand how they work, but I don't understand how to know before hand what the output of a Matrix will look like. For example lets say I want to add a blur to an image, I could guess 10,000+ different combinations of numbers before I get the correct one. I do know though that this formula will give me a blur effect, but I have no idea why. float[] sharpen = new float[] { 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f }; Can anyone either explain to me how this works or point me to some article, that explains this? I would like to know before hand what a possible output of the matrix will be without guessing. Basically I would like to know why do we put that number in the filed, and why not some other number?

  Hello, I am using the code below for a user login. The first I try to login after cache / cookies, etc. have been cleared, the browser refreshes and the user name is not logged in.

• PHP float bug: PHP Hangs On Numeric Value

  - by jeroen

  I just read an interesting article about php hanging on certain float numbers, see The Register and Exploring Binary. I never explicitly use floats, I use number_format() to clean my input and display for example prices. Also, as far as I am aware, all input from for example forms are strings until I tell them otherwise so I am supposing that this problem does not affect me. Am I right, or do I need to check for example Wordpress and Squirrelmail installations on my server to see if they cast anything to float? Or better, grep all php files on my servers for float?

• Ruby on Rails: How best to escape a string in a model?

  - by williamjones

  I want my application to sanitize html on input rather than on display, so that the fields saved into the database are sanitized. I've been doing this with strip_tags, and it was working great. However, this has the downside that it means the user can't input anything that's bracketed with < and . How can I tell Rails in the model to securely escape tags before saving them to the database? I'd like to not have to call h on the sanitized fields again before using them in the views.

• need some tips on Drupal $form value

  - by bert

  I got dpm($form) working. Nice! This is much better way to view data. I am still trying to figure out where stuff is coming from eg: location longitude & latitude. The word 'longitude' is referenced in 20 different places. I thought this was a likely place to isolate text box for this input field. dpm($form['#field_info']['field_store_latitude']['location_settings']['form']['fields']); Any tips on how to track down individual input elements?

• On Click alert if $.get returns a value, if not, submit the form

  - by bradenkeith

  If the submit button is clicked, prevent the default action and see if the field 'account_name' is already in use. If the $.get() returns a result, alert the user of the results. If it doesn't, submit form with id="add_account_form". My problem is that my else{} statement is not submitting the form. I get no response when submit is clicked & there is no value returned. Also I would like to change my code where it goes $("#add_account_form").submit(..) instead of .click() however, would that cause a problem when trying to submit the form later in the script? <script type="text/javascript"> $(document).ready( function () { $("#submit").click( function () { var account_name = $("input[name=account_name]").val(); $.get( "'.url::site("ajax/check_account_name").'", {account_name: account_name}, function(data){ if(data.length > 0){ confirm( "The account name you entered looks like the following:\n" +data+ "Press cancel if this account already exists or ok to create it." ); }else{ $("#add_account_form").submit(); } }); return false; }); }); </script> <p> <input type="submit" id="submit" class="submit small" name="submit" value="Submit" /> </p> </form> Thanks for your help. EDIT So anyone who runs into my problems, it's that $.get() is asynchronous, so it will always return false, or true depending on what submitForm is defined as. $.ajax() however, allows async to be set as false, which allows the function to finish before moving on. See what I mean: $(document).ready( function () { $("#add_account_form").submit( function () { var submitForm = true; var account_name = $("input[name=account_name]").val(); $.ajax({ type: "GET", async: false, url: "'.url::site("ajax/check_account_name").'", data: ({account_name: account_name}), success: function(data){ if(data.length > 0){ if(!confirm( "The account name you entered looks like the following:\n" +data+ "Press cancel if this account already exists or ok to create it." )){ submitForm = false; } } } }); if (submitForm == false ) { return false; } }); }); Thanks for your help @Dan

• Issue with plotting daily data using ggplot

  I tried to plot daily data from 9 variables in ggplot, but the graph I get cannot handle the date variable properly. The x axis is unreadable and its impossible to read the plot. I'm guessing there's an issue with the handling of dates. Here's the data: https://dl.dropbox.com/u/22681355/su.csv Here's the code I've been using: su=read.csv(file="su.csv", head=TRUE) meltdf=melt(su) ggplot(meltdf, aes(x=Date, y=value, colour=variable, group=variable))+geom_line() and here's the output: https://dl.dropbox.com/u/22681355/output.jpg here's the same plot done in excel, why does it look completely different?

• how is this jquery app validating the username? (3rd party script)

  - by SarmenHB

  The tutorial that I'm trying to figure out is this: http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/ The username field looks like this: <input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" /> That <input> field has a class item named ajax[ajaxUser] which has its rules contained in this script (jquery.validationEngine-en.js). The snippet for that item looks like this: "ajaxUser":{ "file":"validateUser.php", "extraData":"name=eric", "alertTextOk":"* This user is available", "alertTextLoad":"* Loading, please wait", "alertText":"* This user is already taken"}, What I can't figure out at all is how its PHP page is working which is validateUser.php. Where are all those post fields coming from? I looked around and can't find a field with those names. Thanks

• Dynamically/recursively building hashes in Perl?

  - by Gaurav Dadhania

  I'm quite new to Perl and I'm trying to build a hash recursively and getting nowhere. I tried searching for tutorials to dynamically build hashes, but all I could find were introductory articles about hashes. I would be grateful if you point me towards the right direction or suggest a nice article/tutorial. I'm trying to read from a file which has paths in the form of one/two/three four five/six/seven/eight and I want to build a hash like VAR = { one : { two : { three : "" } } four : "" five : { six : { seven : { eight : "" } } } } The script I'm using currently is : my $finalhash = {}; my @input = <>; sub constructHash { my ($hashrf, $line) = @_; @elements = split(/\//, $line); if(@elements > 1) { $hashrf->{shift @elements} = constructHash($hashrf->{$elements[0]}, @elements ); } else { $hashrf->{shift @elements} = ""; } return $hashrf; } foreach $lines (@input) { $finalhash = constructHash($finalhash, $lines); }

• Splitting a double vector into equal parts

  - by Cosmin

  Greetings, Any input on a way to divide a std::vector into two equal parts ? I need to find the smallest possible difference between |part1 - part2|. This is how I'm doing it now, but from what you can probably tell it will yield a non-optimal split in some cases. auto mid = std::find_if(prim, ultim, [&](double temp) -> bool { if(tempsum >= sum) return true; tempsum += temp; sum -= temp; return false; }); The vector is sorted, highest to lowest, values can indeed appear twice. I'm not expecting part1 and part2 to have the same numbers of elements, but sum(part1) should be as close as possible to sum(part2) For example if we would have { 2.4, 0.12, 1.26, 0.51, 0.70 }, the best split would be { 2.4, 0.12 } and { 1.26, 0.51, 0.70 }. If it helps, I'm trying to achieve the splitting algorithm for the Shannon Fano encoding. Any input is appreciated, thanks!
