• I need my BizTalk map to stop converting xml:lang to ns1:lang

  - by Jeremy Stein

  I have a map in BizTalk 2009 that is converting some data into an XML document to be sent on to another system. The target schema includes some elements with xml:lang attributes. BizTalk generates those as ns1:lang. The target system requires that the prefix xml be used. Here is a simplified example to show what BizTalk is doing: sample.xsd <xs:schema targetNamespace="http://example.com/" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:import schemaLocation="common.xsd" namespace="http://www.w3.org/XML/1998/namespace" /> <xs:element name="example"> <xs:complexType> <xs:attribute ref="xml:lang" /> </xs:complexType> </xs:element> </xs:schema> common.xsd <?xml version="1.0" encoding="utf-16"?> <xs:schema xmlns:xml="http://www.w3.org/XML/1998/namespace" targetNamespace="http://www.w3.org/XML/1998/namespace" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:attribute name="lang" type="xs:language" /> </xs:schema> Example of map output <ns0:example xmlns:ns0="http://example.com/" xmlns:ns1="http://www.w3.org/XML/1998/namespace" ns1:lang="en-US" /> Is there some way to convince BizTalk to use the xml prefix?

• Make sure <a href="local file"> is opened outside of browser

  - by Heinzi

  For an Intranet web application (document management), I want to show a list of files associated with a certain customer. The resulting HTML is like this: <a href="file:///server/share/dir/somefile.docx">somefile.docx</a> <a href="file:///server/share/dir/someotherfile.pdf">somefile.pdf</a> <a href="file:///server/share/dir/yetanotherfile.txt">yetanotherfile.txt</a> This works fine. Unfortunetly, when clicking on a text file (or image file), Internet Explorer (and I guess most other browsers as well) insist on showing it in the browser instead of opening the file with the associated application (e.g. Notepad). In our case, this is undesired behavior, since it does not allow the user to edit the file. Is there some workaround to this behavior (e.g. something like <a href="file:///..." open="external">)? I'm aware that this is a browser-specific thing, and an IE-only solution would be fine (it's an Intranet application after all).

• use of assertions for type checking in php?

  - by user151841

  I do some checking of arguments in my classes in php using exception-throwing functions. I have functions that do a basic check ( ===, in_array etc ) and throw an exception on false. So I can do assertNumeric($argument, "\$argument is not numeric."); instead of if ( ! is_numeric($argument) ) { throw new Exception("\$argument is not numeric."); } Saves some typing I was reading in the comments of the php manual page on assert() that As noted on Wikipedia - "assertions are primarily a development tool, they are often disabled when a program is released to the public." and "Assertions should be used to document logically impossible situations and discover programming errors— if the 'impossible' occurs, then something fundamental is clearly wrong. This is distinct from error handling: most error conditions are possible, although some may be extremely unlikely to occur in practice. Using assertions as a general-purpose error handling mechanism is usually unwise: assertions do not allow for graceful recovery from errors, and an assertion failure will often halt the program's execution abruptly. Assertions also do not display a user-friendly error message." This means that the advice given by "gk at proliberty dot com" to force assertions to be enabled, even when they have been disabled manually, goes against best practices of only using them as a development tool So, am I 'doing it wrong'? What other/better ways of doing this are there?

• Jquery menu with less code

  - by Sergio

  I'm using Jquery for menu created like: <div class="prof_info1">home</div><div class="prof_info2">info2</div><div class="prof_info3">info3</div> And Jquery code like: $(document).ready(function(){ $(".prof_info1").unbind("click").click(function(event) { $("#main").html('<img src="img/spin.gif" class="spin">'); location.replace("?&id=<?=$id?>") return false; }); $(".prof_info2").unbind("click").click(function(event) { $("#main").html('<img src="img/spin.gif" class="spin">'); $("#main").load('?a=2&id=<?=$id?>'); return false; }); $(".prof_info3").unbind("click").click(function(event) { $("#glavni").html('<img src="img/spin.gif" class="spin">'); $("#glavni").load('?a=3&id=<?=$id?>'); return false; }); }); Is there any easier way to do write this Jquery code and make it with less code? Something like if click somethind{ ... }elseif{ ....}

• how to match var/id to class

  - by circey

  Hi. I'm new to jquery and, in addition, I think I'm having a brain freeze. I have a number of links with different ids. I want to match the clicked link with a div with the corresponding class so the div will show/hide/toggle as appropriate. I have: <script type="text/javascript"> $(document).ready(function() { $('.folioBox').hide(); $('a.interface').click(function(){ var currentId = $(this).attr('id'); var currentBox = $('.folioBox .' + currentId); $(currentBox).toggle(400); }); }); </script> <a class="interface" id="apple">Apple flavor</a> <a class="interface" id="banana">Banana flavor</a> <a class="interface" id="cherry">Cherry flavor</a> <div class="folioBox apple">content</div> <div class="folioBox banana">content</div> <div class="folioBox cherry">content</div> I just can't get it to work and I can't figure out whether I would be best using match or find or filter. Some assistance would be much appreciated!

• MongoDB architectural question

  - by pex

  I have to store 4 Models. Let's say a Post that has many and belongs to many Categories. Category on the other hand has many Qualities. At the moment I'm of the opinion, that Post and Categories are Documents. Qualities becomes an EmbeddedDocument of Categories. We're coming to the root problem: There are a lot of Votes on Qualities that belong to a Post. I thought about embed Votes in Post and give it a quality_id. I am really expecting a lot of Votes and there has to be a possibility to filter them (e.g by Username / Usergroup / Date voted). I worked with MongoMapper and I think the missing existence of find methods for EmbeddedDocuments could become a killer. On the other hand I'm wondering about performance issues. What if I want to provide a Post without all the Votes, but only a few. Or, what if I define an own Document for Votes and have tons of Vote-Documents? Wouldn't that become a performance killer?

• jQuery + Jeditable - detect when select is changed

  - by Bryan Roth

  I'm using Jeditable for in-place editing. One the controls I am working with has the select type. When a user clicks on the field, the following select control is generated: <div id="status" class="editable_select"> <form> <select name="value"> <option value="Active">Active</option> <option value="Inactive">Inactive</option> </select> <button type="submit">Save</button> <button type="cancel">Cancel</button> </form> </div> What I am trying to figure out is how to use jQuery to detect when that select control is changed, especially since it doesn't have an ID attribute. This is what I have so far, but the event is not getting triggered: $(document).ready(function () { $('#status select').change(function () { alert("Change Event Triggered On:" + $(this).attr("value")); }); });

• jQuery ajax success not work in codeigniter

  - by softboxkid

• jquery filter .not()

  - by FFish

  I have a form with image thumbnails to select with checkboxes for downloading. I want an array with the images in jQuery for an Ajax call. 2 questions: - On the top of the table there is a checkbox to toggle all checkboxes that I want to exclude from the mapping. I had a look at jQuery's .not() but I can't implement it with the :checkbox selector - is the following example code correct? $(document).ready(function() { $('#myform').submit(function() { var images = $("input:checkbox", this).map(function() { return $(this).attr("name"); }).get().join(); alert(products); // outputs: ",check1,check2,check3" return false; // cancel submit action by returning false }); }); // end doc ready HTML: <form id="myform" action="" > <input type="checkbox" id="toggleCheck" onclick="toggleSelectAll()" checked="checked" ><br /> <input type="checkbox" name="001.jpg" checked="checked" /><br /> <input type="checkbox" name="002.jpg" checked="checked" /><br /> <input type="checkbox" name="003.jpg" checked="checked" /><br /> <br /> <input type="submit" value="download" > </form>

• Best practices for Java logging from multiple threads?

  - by Jason S

  I want to have a diagnostic log that is produced by several tasks managing data. These tasks may be in multiple threads. Each task needs to write an element (possibly with subelements) to the log; get in and get out quickly. If this were a single-task situation I'd use XMLStreamWriter as it seems like the best match for simplicity/functionality without having to hold a ballooning XML document in memory. But it's not a single-task situation, and I'm not sure how to best make sure this is "threadsafe", where "threadsafe" in this application means that each log element should be written to the log correctly and serially (one after the other and not interleaved in any way). Any suggestions? I have a vague intuition that the way to go is to use a queue of log elements (with each one able to be produced quickly: my application is busy doing real work that's performance-sensitive), and have a separate thread which handles the log elements and sends them to a file so the logging doesn't interrupt the producers. The logging doesn't necessarily have to be XML, but I do want it to be structured and machine-readable. edit: I put "threadsafe" in quotes. Log4j seems to be the obvious choice (new to me but old to the community), why reinvent the wheel...

• CSS 3 - Scaling CSS Transitions

  - by Viv Shc

  I am trying to scale an image when you mouseenter, which is working. I would like the image to gradually scale up with an ease transition. I used ease-in-out, which it's not working. Any suggestions? Also, I used addClass & removeClass twice in the jquery code. Is there a way to only use it once? Thanks! <style> .image { opacity: 0.5; } .image.opaque { opacity: 1; } .size{ transform:scale(1.2); -ms-transform:scale(1.2); /* IE 9 */ -webkit-transform:scale(1.2); /* Safari and Chrome */ -webkit-transition: scale 2s ease-in-out; -moz-transition: scale 2s ease-in-out; -o-transition: scale 2s ease-in-out; -ms-transition: scale 2s ease-in-out; transition: scale 2s ease-in-out; transition: opacity 2s; } </style> <script> $(document).ready(function() { $(".image").mouseenter(function() { $(this).addClass("opaque"); $(this).addClass("size"); }); $(".image").mouseleave(function() { $(this).removeClass("opaque"); $(this).removeClass("size"); }); }); <div id="gallery"> <h3>Gallery of images</h3> <img class="image" src="images/gnu.jpg" height="200px" width="250px"> <img class="image" src="images/tiger.jpg" height="200px" width="250px"> <img class="image" src="images/black_rhino.jpg" height="200px" width="250px"> <img class="image" src="images/cape_buffalo.jpg" height="200px" width="250px"> </div>

• PHP jQuery Long Polling Chat Application

  - by Tejas Jadhav

  I've made a simple PHP jQuery Chat Application with Short Polling (AJAX Refresh). Like, every 2 - 3 seconds it asks for new messages. But, I read that Long Polling is a better approach for Chat applications. So, I went through some Long Polling scripts. I made like this: Javascript: $("#submit").click(function(){ $.ajax({ url: 'chat-handler.php', dataType: 'json', data: {action : 'read', message : 'message'} }); }); var getNewMessage = function() { $.ajax({ url: 'chat-handler.php', dataType: 'json', data: {action : 'read', message : 'message'}, function(data){ alert(data); } }); getNewMessage(); } $(document).ready(getNewMessage); PHP <?php $time = time(); while ((time() - $time) < 25) { $data = $db->getNewMessage (); if (!empty ($data)) { echo json_encode ($data); break; } usleep(1000000); // 1 Second } ?> The problem is, once getNewMessage() starts, it executes unless it gets some response (from chat-handler.php). It executes recursively. But if someone wants to send a message in between, then actually that function ($("#submit").click()) never executes as getNewMessage() is still executing. So is there any workaround?

• Jquery - custom countdown

  - by matthewsteiner

  So I found this countdown at http://davidwalsh.name/jquery-countdown-plugin, I altered it a little bit: jQuery.fn.countDown = function(settings,to) { settings = jQuery.extend({ duration: 1000, startNumber: $(this).text(), endNumber: 0, callBack: function() { } }, settings); return this.each(function() { //where do we start? if(!to && to != settings.endNumber) { to = settings.startNumber; } //set the countdown to the starting number $(this).text(to); //loopage $(this).animate({ 'fontSize': settings.endFontSize },settings.duration,'',function() { if(to > settings.endNumber + 1) { $(this).text(to - 1).countDown(settings,to - 1); } else { settings.callBack(this); } }); }); }; Then I have this code: $(document).ready(function(){ $('.countdown').countDown({ callBack: function(me){ $(me).text('THIS IS THE TEXT'); } }); }); I don't mind taking everything out of the "animate" loop; I'd prefer that since nothing needs to be animated. (I don't need the font size to change). So everything's working to a point. I have a span with class countdown and whatever is in it when the page is refreshed goes down second by second. However, I need it to be formatted in M:S format. So, my two questions: 1) What can I use instead of animate to take care of the loop yet maintain the callback 2) How (where in the code should I) can I play with the time format? Thanks.

• using jquery growl with php/mysql

  - by jeansymolanza

  on my database i am planning to create a table storing messages to alert users of anything they need to do. i am looking at using a jQuery growl like notification method but im confused at how i would begin building it. the data would be added into the database using the standard MYSQL insert method from a form but how would i select messages from the database to display using the jQuery growl. would this require the use of ajax? this is the javascript code i have so far, i was wondering how i would implement the php code alongside it so that i can pull out data from my tables to display as notifications: <script type="text/javascript"> // In case you don't have firebug... if (!window.console || !console.firebug) { var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml", "group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"]; window.console = {}; for (var i = 0; i < names.length; ++i) window.console[names[i]] = function() {}; } (function($){ $(document).ready(function(){ // This specifies how many messages can be pooled out at any given time. // If there are more notifications raised then the pool, the others are // placed into queue and rendered after the other have disapeared. $.jGrowl.defaults.pool = 5; var i = 1; var y = 1; setInterval( function() { if ( i < 3 ) { $.jGrowl("Message " + i, { sticky: true, log: function() { console.log("Creating message " + i + "..."); }, beforeOpen: function() { console.log("Rendering message " + y + "..."); y++; } }); } i++; } , 1000 ); }); })(jQuery); </script> <p> thanking you in advance and God bless

• Colorbox with bxslider not working

  - by Bill K

  Hello I am trying to use bxslider with colorbox. My implementation of bxslider is like an example listed here. The difference is that I want only the pagers to be shown. Also when the user clicks one pager I want colorbox to open and have next and previous buttons. The problem is that I cant group the images with colorbox and next and previous button is not shown! The following code uses the rel option but with this way colorbox doesnt event start. What I have tried till now is: HTML <div class="slider_mini" style="position:relative;bottom:0px;"> <div id="bx-pager"> <a data-slide-index="0" href="image.jpg" class="imgz"><img style="width:130px;height:104px;" src="image.jpg"/></a> <a data-slide-index="1" href="image2.jpg" class="imgz"><img style="width:130px;height:104px;" src="image2.jpg"/></a> <a data-slide-index="2" href="image3.jpg" class="imgz"><img style="width:130px;height:104px;" src="image3.jpg"/></a> </div> </div> SCRIPT <script type="text/javascript"> $(document).ready(function(){ $('.imgz').colorbox({rel:'imgz'}); $('.bxslider.two').bxSlider({ pagerCustom: '#bx-pager' }); $('#bx-pager').bxSlider({ slideWidth: 130, minSlides: 2, maxSlides: 3, moveSlides: 1, slideMargin: 10 }); }); </script> Not working Fiddle. Feedback: The problem was in live website that I was calling colorbox before bxslider. I put the call after bxslider's and it works. Thank you.

• My images aren't updating immediately upon changing their src in javascript

  - by Dale

  I'm using the function below to change the img src. It's an array of ten images. When going through the loop, using break points, the images don't all update on the page immediately. Some of them do. If I inspect the unchanged images on the page (while paused at a breakpoint), the src has changed, but the image hasn't changed yet. All of the unchanged images get updated correctly when the function ends. Anyone know why they don't all get updated instantly and how I can force them to update? Also, is there a way I can hold off the updates of all of them until they're all reassigned and thus have them all update on the "simultaneously"? Here's my function. function mainFunction(){ finalSet = calculateSet(); for ( var int = 0; int < finalSet.length; int++) { var fileName = "cardImg" + (int); document.getElementById(fileName).src = "images/cards/" + finalSet[int].name + ".jpg"; } } Thanks for the help.

• How to access CSS generated content with JavaScript

  - by Boldewyn

  I generate the numbering of my headers and figures with CSS's counter and content properties: img.figure:after { counter-increment: figure; content: "Fig. " counter(section) "." counter(figure); } This (appropriate browser assumed) gives a nice labelling "Fig. 1.1", "Fig. 1.2" and so on following any image. Question: How can I access this from Javascript? The question is twofold in that I'd like to access either the current value of a certain counter (at a certain DOM node) or the value of the CSS generated content (at a certain DOM node) or, obviously, both information. Background: I'd like to append to links back-referencing to figures the appropriate number, like this: <a href="#fig1">see here</h> ------------------------^ " (Fig 1.1)" inserted via JS As far as I can see, it boils down to this problem: I could access content or counter via getComputedStyle: var fig_content = window.getComputedStyle( document.getElementById('fig-a'), ':after').content; However, this is not the live value, but the one declared in the stylesheet. I cannot find any interface to access the real live value.

• How do you query namespaces with PHP/XPath/DOM

  - by Alsbury

  I am trying to query an XML document that uses namespaces. I have had success with xpath without namespaces, but no results with namespaces. This is a basic example of what I was trying. I have condensed it slightly, so there may be small issues in my sample that may detract from my actual problem. Sample XML: <?xml version="1.0"?> <sf:page> <sf:section> <sf:layout> <sf:p>My Content</sf:p> </sf:layout> </sf:section> </sf:page> Sample PHP Code: <?php $path = "index.xml"; $content = file_get_contents($path); $dom = new DOMDocument($content); $xpath = new DOMXPath($dom); $xpath->registerNamespace('sf', "http://developer.apple.com/namespaces/sf"); $p = $xpath->query("//sf:p", $dom); My result is that "p" is a "DOMNodeList Object ( )" and it's length is 0. Any help would be appreciated.

• Chaining functions in jQuery. I cannot find an explanation anywhere.

  - by Marius

  Hello there, I have no idea how to do this. My markup: <table> <tr> <td id="colLeft"> Lorem ipsum dolor<br/> Lorem ipsum dolor<br/> Lorem ipsum dolor<br/> Lorem ipsum dolor<br/> Lorem ipsum dolor<br/> Lorem ipsum dolor. </td> <td id="colRight"> <div>1</div> <div>2</div> </td> </tr> </table> $(document).ready(function() { $('#colRight > div').each(function() { // I try to: select all divs in #colRight $(this).height(function(){ // I try to: sets the height of each div to: $('#colLeft').height() / $('#colRight > div').length(); // the height of #colLeft divided by the number of divs in colRight. }); }); }); What I am trying to do is to change the height of each div to the height of #colLeft divided by the number of divs in #colRight. However, it doesnt work. I've never understood how to chain functions, and never found anyone to teach me. So I would like to ask two favours of you. Why doesnt my above jQuery code. Does anyone know of a tutorial that explains it more detailed than in the tutorials on the jQuery website? Thank you for your time. Kind regards, Marius

• img onload doesn't work well in IE7

  - by rmeador

  I have an img tag in my webapp that uses the onload handler to resize the image: <img onLoad="SizeImage(this);" src="foo" > This works fine in Firefox 3, but fails in IE7 because the image object being passed to the SizeImage() function has a width and height of 0 for some reason -- maybe IE calls the function before it finishes loading?. In researching this, I have discovered that other people have had this same problem with IE. I have also discovered that this isn't valid HTML 4. This is our doctype, so I don't know if it's valid or not: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Is there a reasonable solution for resizing an image as it is loaded, preferably one that is standards-compliant? The image is being used for the user to upload a photo of themselves, which can be nearly any size, and we want to display it at a maximum of 150x150. If your solution is to resize the image server-side on upload, I know that is the correct solution, but I am forbidden from implementing it :( It must be done client side, and it must be done on display. Thanks. Edit: Due to the structure of our app, it is impractical (bordering on impossible) to run this script in the document's onload. I can only reasonably edit the image tag and the code near it (for instance I could add a <script> right below it). Also, we already have Prototype and EXT JS libraries... management would prefer to not have to add another (some answers have suggested jQuery). If this can be solved using those frameworks, that would be great. Edit 2: Unfortunately, we must support Firefox 3, IE 6 and IE 7. It is desirable to support all Webkit-based browsers as well, but as our site doesn't currently support them, we can tolerate solutions that only work in the Big 3.

• Retrieve click() handler in jQuery for later use

  - by Xiong Chiamiov

  I'm using the jQuery tablesorter plugin to sort a table, which assigns .click() handlers to the <th>s in the table. Since my table has alternating colors for each column, I've built a simple fix_table_colors(identifier) function that does as it should when I call it manually using Firebug. I would like, however, to have that automatically called after a sort. To do this, I decided to retrieve the .click() handler from the <th>s, and assign a new handler that simply calls the previous handler, followed by fix_table_colors(). (This SO question is similar, but uses standard onClick() attributes, which won't work here.) From the accepted answer to this question, I have created the following code: $(document).ready(function() { $("table.torrents").tablesorter({ debug: true, headers: { 1: { sorter: 'name' }, 2: { sorter: 'peers' }, 3: { sorter: 'filesize' }, 4: { sorter: 'filesize' }, 5: { sorter: 'filesize' }, 6: { sorter: 'ratio' } } }); $('table.torrents thead th').each(function() { var th = $(this); var clickHandler = th.data('events').click[0]; th.click(function() { clickHandler(); fix_table_colors('table.torrents'); }); }); }); While this is conceptually correct, clickHandler doesn't appear to actually be a function, and so I cannot call it. With a bit more digging in Firebug, I found that click[3] appears to hold the function I'm looking for (and click[10] my new one). I get an 'e is undefined' error on line 2 of tablesorter.min.js when using that, though. Am I even going down the right path? I have a feeling that with what I've found so far, I can make this work, but it's going to be much uglier than I would expect it needs to be.

• Why does 12:20 PM parse to 0:20 on the next day?

  - by Hanno Fietz

  I'm using java.text.SimpleDateFormat to parse string representations of date/time values inside an XML document. I'm seeing all times that have an hour value of 12 shifted by 12 hours into the future, i. e. 20 minutes past noon gets parsed to mean 20 minutes past midnight the following day. I wrote a unit test which seems to confirm that the error is made upon parsing (I checked the return values from getTime() with the linux shell command date). Now I'm wondering: is there a bug in the parse() method? is there something wrong with the input string? am I using the wrong format string for the input? The input data is taken from Yahoo's YWeather service. Here's the test and its output: public class YWeatherReaderTest { public static final String[] rgDateSamples = { "Thu, 08 Apr 2010 12:20 PM CEST", "Thu, 08 Apr 2010 12:20 AM CEST" }; public void dateParsing() throws ParseException { DateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy K:m a z", Locale.US); for (String dtsSrc : YWeatherReaderTest.rgDateSamples) { Date dt = formatter.parse(dtsSrc); String dtsDst = formatter.format(dt); System.out.println(dtsSrc); System.out.println(dtsDst); System.out.println(); } } } Thu, 08 Apr 2010 12:20 PM CEST Fri, 09 Apr 2010 0:20 AM CEST Thu, 08 Apr 2010 12:20 AM CEST Thu, 08 Apr 2010 0:20 PM CEST The second output line of the second iteration is slightly weird, because 00:20 isn't PM. The milliseconds value of the Date object, however, corresponds to the (wrong) time of 20 minutes past noon.

• Uncompress OpenOffice files for better storage in version control

  - by Craig McQueen

  I've heard discussion about how OpenOffice (ODF) files are compressed zip files of XML and other data. So making a tiny change to the file can potentially totally change the data, so delta compression doesn't work well in version control systems. I've done basic testing on an OpenOffice file, unzipping it and then rezipping it with zero compression. I used the Linux zip utility for my testing. OpenOffice will still happily open it. So I'm wondering if it's worth developing a small utility to run on ODF files each time just before I commit to version control. Any thoughts on this idea? Possible better alternatives? Secondly, what would be a good and robust way to implement this little utility? Bash shell that calls zip (probably Linux only)? Python? Any gotchas you can think of? Obviously I don't want to accidentally mangle a file, and there are several ways that could happen. Possible gotchas I can think of: Insufficient disk space Some other permissions issue that prevents writing the file or temporary files ODF document is encrypted (probably should just leave these alone; the encryption probably also causes large file changes and thus prevents efficient delta compression)
