• Load first page on splashscreen using phonegap on android

  - by Syg

  Hi i'm using phonegap in conjunction with Jquery mobile. I'm trying to immediately fetch the main page, while showing the user a splashscreen. In PhoneGap for Android i'm using this super.setIntegerProperty("splashscreen", R.drawable.splash); super.loadUrl("file:///android_asset/www/index.html", 2000); While this loads the splash, it also delays the loading of index.html. It it possible to start fetching it right away? Also, if not with phonegap, has anybody done this using JQM instead of phonegap? UPDATE: After using it with a slower loading first page (doing a json request) it kinda looks like the splash screens shows for a longer period of time, so this appears to be the default behavior

• addEventListener gone after appending innerHTML

  - by Vishal Shah

  Okay, so i have the following html added to a site using javascript/greasemonkey. (just sample) *a id='abc'*HEllo*/a* *a id='xyz'*Hello*/a* (excuse me, i've had to replace the '<' '' with * since hyperlinks for new users aren't allowed!) and i've also added a click event listener for the elements. All works fine up to this point, the click event gets fired when i click the element. But... i have another function in the script, which upon a certain condition, modifies that html, ie it appends it, so it looks like: *a id='abc'*HEllo*/a* *a id='xyz'*Hello*/a* *a id='123'*Hello*/a* but when this is done, it breaks the listeners i added for the first two elements... nothing happens when i click them. if i comment out the call to the function which does the appending, it all starts working again! help please...

• How to prevent direct access to my JSON service?

  - by FrankLy

  I have a JSON web service to return home markers to be displayed on my Google Map. Essentially, http://example.com calls the web service to find out the location of all map markers to display like so: http://example.com/json/?zipcode=12345 And it returns a JSON string such as: {"address": "321 Main St, Mountain View, CA, USA", ...} So on my index.html page, I take that JSON string and place the map markers. However, what I don't want to have happen is people calling out to my JSON web service directly. I only want http://example.com/index.html to be able to call my http://example.com/json/ web service ... and not some random dude calling the /json/ directly. Quesiton: how do I prevent direct calling/access to my http://example.com/json/ web service?

• Watin ContainsText method fails to find text in FireFox

  - by alonp

  The ContainsText method finds the text only in specific area in the html but fails to find id in other parts of the page. The text that located under 'div id="content"' can be found But the text in other area of the html is not found (f.e 'form id="aspnetForm"') Browser b = new FireFox("http://localhost:8668/login.aspx"); b.Button("login.login.button")).Click(); bool blah = b.ContainsText("Hello"); I'm using the latest watin release. The issue is reproduced with FF3.0, FF3.5 and FF3.6 In IE it's working fine for the tested text.

• java checked exception in a catch clause compilation error

  - by srandpersonia

  Hi, I was expecting an compilation error in the following program because of the throw statement in the catch block as IOException is a checked exception and it is not caught by another try block within the catch block. But I am getting "Hurray!" printed. Any explanation would be much appreciated. According to JLS 11.2.3, http://java.sun.com/docs/books/jls/third_edition/html/exceptions.html It is a compile-time error if a method or constructor body can throw some exception type E when both of the following hold: * E is a checked exception type * E is not a subtype of some type declared in the throws clause of the method or constructor. import java.io.*; public class Test{ public static void main(String args[]) { System.out.println(method()); } public static int method() { try{ throw new Exception(); } catch(Exception e){ throw new IOException(); //No compile time error } finally{ System.out.println("Hurray!"); } } } Thanks in advance.

• How to Cache image when src is some action which returns image?

  - by Bipul

  There are lots of questions about how to force the browser to cache or not to cache any image. But, I am facing slightly different situation. In several places of my web page, I am using following code for the images. <img title="<%= Html.Encode(Model.title)%>" src="<%= Url.Action(MVC.FrontEnd.Actions.RetrieveImage(Model.SystemId))%>"/> So, in the generated HTML it is like <img title="blahblah" src="http://xyz.com/FrontEnd/Actions/RetrieveImage?imageId=X"> Where X is some integer. I have seen that though the browser (IE or Mozilla) caches images by default, it is not caching images generated by above method. Is there any way I can tell browser to cache images of above type? Thanks in advance.

• XSL: Dead or not dead

  - by Seattle Leonard

  I'm currently taking on a new project at home. In this project I'm going to be generating HTML emails. For this purpose, I believe XSL to be a good candidate. However, I have heard people say that XSL is a dead language, and if it's not that it is on it's way out. In fact, MS has been very leary to support XSL 2.0. Personally I feel that any time you are going from text to text, it is a great tool. Such as: Generating HTML e-mails Creating Open Office Docs Generating another XML doc What are your thoughts? Is it dead, or is it still a viable, usefull tool?

• Perl: Edit hyperlinks in nested tags that aren't on separate lines

  - by user305801

  I have an interesting problem. I wrote the following perl script to recursively loop through a directory and in all html files for img/script/a tags do the following: Convert the entire url to lowercase Replace spaces and %20 with underscores The script works great except when an image tag in wrapped with an anchor tag. Is there a way to modify the current script to also be able to manipulate the links for nested tags that are not on separate lines? Basically if I have <a href="..."><img src="..."></a> the script will only change the link in the anchor tag but skip the img tag. #!/usr/bin/perl use File::Find; $input="/var/www/tecnew/"; sub process { if (-T and m/.+\.(htm|html)/i) { #print "htm/html: $_\n"; open(FILE,"+<$_") or die "couldn't open file $!\n"; $out = ''; while(<FILE>) { $cur_line = $_; if($cur_line =~ m/<a.*>/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* href=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } if($cur_line =~ m/(<img.*>|<script.*>)/i) { print "cur_line (unaltered) $cur_line\n"; $cur_line =~ /(^.* src=\")(.+?)(\".*$)/i; $beg = $1; $link = html_clean($2); $end = $3; $cur_line = $beg.$link.$end; print "cur_line (altered) $cur_line\n"; } $out .= $cur_line; } seek(FILE, 0, 0) or die "can't seek to start of file: $!"; print FILE $out or die "can't print to file: $1"; truncate(FILE, tell(FILE)) or die "can't truncate file: $!"; close(FILE) or die "can't close file: $!"; } } find(\&process, $input); sub html_clean { my($input_string) = @_; $input_string = lc($input_string); $input_string =~ s/%20|\s/_/g; return $input_string; }

• Jquery load() help

  - by mtwallet

  Hi. I am creating a portfolio page for m personal site. I have a slider with approx 20 anchors that link to projects I have worked on, each one contains a client logo that when clicked should load some html content then fade that content into a container div on the same page. I have been advised to use the JQuery method load() which seems straight forward. The question I have is do I have to repeat the following code for each of the 20 anchors as the url is different for each one or is there a more efficient way? $('a#project1').click(function() { $('#work').load('ajax/project1.html'); } Also would I have to use the unload() method first to ensure the div I am loading into is empty? Many thanks in advance.

• Lookahead regex produces unexpected group

  - by Ivan Yatskevich

  I'm trying to extract a page name and query string from a URL which should not contain .html Here is an example code in Java: public class TestRegex { public static void main(String[] args) { Pattern pattern = Pattern.compile("/test/(((?!\\.html).)+)\\?(.+)"); Matcher matcher = pattern.matcher("/test/page?param=value"); System.out.println(matcher.matches()); System.out.println(matcher.group(1)); System.out.println(matcher.group(2)); } } By running this code one can get the following output: true page e What's wrong with my regex so the second group contains the letter e instead of param=value?

• Getting jQuery slideshow animation to stop on click

  - by hollyb

  I have a slide show built with jQuery that pauses on hover. It has a group of thumbnails sitting on top of the image that advances the image when clicked, otherwise the slideshow just auto-rotates through all the images. There is also a +/- to expand and contract a caption related to each image. I want to have the slideshow's automatic advancing to stop if one of the thumbnails is clicked, or the +/-. Basically, just stop whenever a user clicks anywhere within the gallery (div class=".homeImg"). I'm having a major brain fart in getting this working properly and could use some advice. Here's the jQuery: $(document).ready(function() { $(".main_image .desc").show(); //Show image info $(".main_image .block").animate({ opacity: 0.85 }, 1 ); //Set Opacity //Click and Hover events for thumbnail list $(".image_thumb ul li:first").addClass('active'); // * Adds a class 'last' to the last li to let the rotator know when to return to the first $(".image_thumb ul li:last").addClass('last'); $(".image_thumb ul li").click(function(){ //Set Variables var imgAlt = $(this).find('img').attr("alt"); //Get Alt Tag of Image var imgTitle = $(this).find('a').attr("href"); //Get Main Image URL var imgDesc = $(this).find('.block').html(); //Get HTML of block var imgDescHeight = $(".main_image").find('.block').height(); //Calculate height of block if ($(this).is(".active")) { //If it's already active, then… return false; // Don't click through } else { //Animate $(".main_image img").animate({ opacity: 0}, 800 ); $(".main_image .block").animate({ opacity: 0, marginBottom: -imgDescHeight }, 800, function() { $(".main_image .block").html(imgDesc).animate({ opacity: 0.85, marginBottom: "0" }, 250 ); $(".main_image img").attr({ src: imgTitle , alt: imgAlt}).animate({ opacity: 1}, 250 ); }); } $(".image_thumb ul li").removeClass('active'); //Remove class of 'active' on all lists $(this).addClass('active'); //add class of 'active' on this list only return false; }) .hover(function(){ $(this).addClass('hover'); }, function() { $(this).removeClass('hover'); }); //Toggle teaser $("a.collapse").click(function(){ $(".main_image .block").slideToggle(); $("a.collapse").toggleClass("show"); return false; // added to remove # browser jump }); // If we are hovering over the image area, pause the clickNext function pauseClickNext = false; $(".homeImg").hover( function () { pauseClickNext = true; }, function () { pauseClickNext = false; } ); // Define function to click the next li var clickNext = function(){ if(!pauseClickNext) { /// find the next li after .active var $next_li = $("li.active").next("li"); if($("li.active").hasClass("last") ){ $(".image_thumb ul li:first").trigger("click"); } else { $next_li.trigger("click"); } } }; // Time between image transition setInterval(clickNext, 6000); });

• What are cons if we use javascript to apply css selectors to that browser who do not support that pr

  - by metal-gear-solid

  What are cons if we use JavaScript to apply only CSS property/selectors to that browser who do not support that property by default? to keep my HTML semantic and keep free from Deprecated HTML. Is it against content, style and Behavior separation? If I make accessible site then should i only use whatever i can do with pure css. shouldn't use JavaScript to apply CSS properties. I know those css properties which I'm applying through javascript will not work if javascript is disabled. then due to this reason shouldn't use javascript to apply css never. I'm talking about using these type of stuffs http://www.fetchak.com/ie-css3/ http://code.google.com/p/ie7-js/

• [JavaScript] How to get the uri of the .js file itself.

  - by Vikrant Chaudhary

  Hi, is there a method in JavaScript by which I can find out the path/uri of the executing script. For example: index.html includes a JavaScript file stuff.js and since stuff.js file depends on ./commons.js, it wants to include it too in the page. Problem is that stuff.js only knows the relative path of ./commons.js from itself and has no clue of full url/path. index.html includes stuff.js file as <script src="http://example.net/js/stuff.js?key=value" /> and stuff.js file wants to read the value of key. How to?

• How to use a different assembly name for different configurations?

  - by Mark Ingram

  In Visual Studio 2008 (and others) when creating a .NET or silverlight application if you look at your project properties, it seems like you can only have one assembly name - across all configurations. I would like to compile my application as: MyAppDebug - in debug mode and just MyApp - in release mode Does anyone know if this is possible? Edit: It seems some people are questioning the reasoning behind the question, so I'll explain a little further: I'm working on a Silverlight application which gets automatically uploaded to our test site when I to a "build solution". The trouble is, the test team are now testing the online version, whilst I work on a new one. So, I want to have a url like .\MyApp.html for the regular version that the QA team will test and then .\MyApp.html?version=debug for the current version that I'm working on.

• Is there any alternative to obfuscation to make it harder to get any string in javascript?

  - by MarceloRamires

  I use DropBox and I've had some trouble reaching to my files from other computers: I not always want to login to anything when I'm in a public computer, but I like being able to reach my stuff from wherever I am. So I've made a simple little application that when put in the public folder, ran and given the right UID, creates (still in your public folder) an HTML of all the content in the folder (including subfolders) as a tree of links. But I didn't risk loading it anywhere, since there are slightly private things in there (yes, I know that the folder's name is "PUBLIC"). So I've came up with the idea to make it a simple login page, given the right password, the rest of the page should load. brilliant!, but how? If I did this by redirecting to other HTML on the same folder, I'd still put the html link in the web history and the "url's accessed" history of the administrator. So I should generate itin the same page. I've done it. And currently the page is a textbox and a button, and only if you type in the right password (asked by the generator) the rest of the page loads. The fault is that everything (password, URL's) is easily reachable through the sourcecode. Now, assuming I only want to avoid silly people to get it all too easily, not make a bulletproof all-content-holding NSA certified website, I though about some ways to make these informations a bit harder to get. As you may have already figured, I use a streamwritter to write a .HTM file (head, loop through links, bottom), then it's extremely configurable, and I can come up with a pretty messy-but-working c# code, though my javascript knowledge is not that good. Public links in DropBox look like this: http://dl.dropbox.com/u/3045472/img.png Summarizing: How do I hide stuff (MAINLY the password, of course) in my source-code so that no bumb-a-joe that can read, use a computer and press CTRL+U can reach to my stuff too easily ? PS.: It's not that personal, if someone REALLY wants it, it could never be 100% protected, and if it was that important, I wouldnt put it in the public folder, also, if the dude really wants to get it that hard, he should deserve it. PS2.: "Use the ultra-3000'tron obfuscator!!11" is not a real answer, since my javascript is GENERATED by my c# program. PS3.: I don't want other solutions as "use a serverside application and host it somewhere to redirect and bla bla" or "compress the links in a .RAR file and put a password in it" since I'm doing this ALSO to learn, and I want the thrill of it =)

• Restrict file access from PHP -> Java Applet

  - by aliuy

  I'm writing a portal in PHP that allows users to upload DICOM images, and allow users of the same group to view those DICOM images through a Java Applet. The html code to display images through the viewer looks like this: <APPLET archive=radscaper.jar codebase=./ code=com.divinev.radscaper.Main.class width=100% height=100%> <PARAM NAME=Config VALUE=config.xml> <PARAM NAME=DicomImg1 VALUE="relative_path1/image1.dcm"> </APPLET> So the generated html passes in a file url to the java applet. The problem I'm facing is - files would be stored in a public directory and easily accessed by anyone knowing the file url. Is there a way I can restrict file access to a certain user group?

• XSLT, JSTL e JSF

  - by Paulo S.

  I have a xml file which I want to transform in a jsf code page. To do that I've created a xsl file. xml: <?xml version='1.0' encoding='ISO-8859-1'?> <questionario xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='Schema2.xsd'> <componente nome='input'> <id>input1</id> </componente> <componente nome='input'> <id>input2</id> </componente> </questionario> code: <%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x" %> <c:set var="xml" value="${questionarioXSLBean.xml}"/> <c:set var="xsl"> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" exclude-result-prefixes="f h"> <xsl:template match="/"> <xsl:for-each select="questionario/componente"> <xsl:if test="attribute::nome = 'input'"> <xsl:variable name="id"> <xsl:value-of select="id" /> </xsl:variable> <h:inputText id="{$id}"/> </xsl:if> </xsl:for-each> </xsl:template> </xsl:stylesheet> </c:set> <x:transform xml="${xml}" xslt="${xsl}" /> The problem is that nothing is shown in my screen because the generated code for <h:inputText id="input1"/> is <h:inputText id="input_1" xmlns:h="http://java.sun.com/jsf/html"/> how can I replace the xmlns:h="http://java.sun.com/jsf/html" or suppress it. Thanks! Update: Let me clarify what I want to do. I want to generate a jsf page dynamically depending on the attributes of a xml file, for instance, 2 input texts, 3 check boxes, etc. To make the transformation to jsf I thought in two approaches, one using jstl and another using xslt. The problem with the former is that I couldn't integrate jstl with jsf code (to set jsf components attributes using jstl variables) and with the last approach, I'm facing the problem described above.I wouldn't like to create components in java (UIComponents). Any suggestions?

• What if I have an API method and a contoller/view method with the same name in RoR?

  - by Chad Johnson

  Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

• IE8 isn't resizing tbody or thead when a column is hidden in a table with table-layout:fixed

  - by tom

  IE 8 is doing something very strange when I hide a column in a table with table-layout:fixed. The column is hidden, the table element stays the same width, but the tbody and thead elements are not resized to fill the remaining width. It works in IE7 mode (and FF, Chrome, etc. of course). Has anyone seen this before or know of a workaround? Here is my test page - toggle the first column and use the dev console to check out the table, tbody and thead width: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>bug</title> <style type="text/css"> table { table-layout:fixed; width:100%; border-collapse:collapse; } td, th { border:1px solid #000; } </style> </head> <body> <table> <thead> <tr> <th id="target1">1</th> <th>2</th> <th>3</th> <th>4</th> </tr> </thead> <tbody> <tr> <td id="target2">1</td> <td>2</td> <td>3</td> <td>4</td> </tr> </tbody> </table> <a href="#" id="toggle">toggle first column</a> <script type="text/javascript"> function toggleFirstColumn() { if (document.getElementById('target1').style.display=='' || document.getElementById('target1').style.display=='table-cell') { document.getElementById('target1').style.display='none'; document.getElementById('target2').style.display='none'; } else { document.getElementById('target1').style.display='table-cell'; document.getElementById('target2').style.display='table-cell'; } } document.getElementById('toggle').onclick = function(){ toggleFirstColumn(); return false; }; </script> </body> </html>

• Can't get message body of certain emails from inbox using the Zend framework?

  Hi guys I'm trying to read through an email inbox for my application - I'm using the zend framework here. The problem is that I'm unable to retrieve the message body for certain emails. The following is my code as to how I'm doing this: $mail = new Zend_Mail_Storage_Imap($mail_options); $all_messages = array(); $page = isset($_GET['page'])?$_GET['page']:1; $limit = isset($_GET['limit'])?$_GET['limit']:20; $offset = (($page-1)*$limit)+1; $end = ($page*$limit)>$c?$c:($page*$limit); for ($i=$offset;$i<=$end;$i++){ $h2t = new html2text(); $h2t->set_allowed_tags('<a>'); if(!$mail[$i]) break; else{ $one_message = $mail->getMessage($i); $one_message->id = $i; $one_message->UID = $mail->getUniqueId($i); $one_message->parts = array(); $one_message->body = ''; $count = 1; foreach (new RecursiveIteratorIterator($mail->getMessage($i)) as $ii=>$part) { try { $tpart = $part; //$tpart->_content = ''; $one_message->parts[$count] = $tpart; $count++; // check for html body if (strtok($part->contentType, ';') == 'text/html') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->html_body = $b; $h2t->set_html($b); $one_message->body = $h2t->get_text(); } //check for text body if (strtok($part->contentType, ';') == 'text/plain') { $b = $part->getContent(); if($part->contentTransferEncoding == 'quoted-printable') $b = quoted_printable_decode($b); $one_message->text_body = $b; $one_message->body = $b;//$part->getContent(); } } catch (Zend_Mail_Exception $e) { // ignore } } $all_messages[] = $one_message; } } The problem is that randomly some messages don't return even a textbody or an html body. Even though if I check using a webvmail client those emails have a message body as well. WHat am I missing here?
