How can I make PHP scripts timeout gracefully while waiting for long-running MySQL queries?

- by Mark B

I have a PHP site which runs quite a lot of database queries. With certain combinations of parameters, these queries can end up running for a long time, triggering an ugly timeout message. I want to replace this with a nice timeout message themed according to the rest of my site style. Anticipating the usual answers to this kind of question: "Optimise your queries so they don't run for so long" - I am logging long-running queries and optimising them, but I only know about these after a user has been affected. "Increase your PHP timeout setting (e.g. set_time_limit, max_execution_time) so that the long-running query can finish" - Sometimes the query can run for several minutes. I want to tell the user there's a problem before that (e.g. after 30 seconds). "Use register_tick_function to monitor how long scripts have been running" - This only gets executed between lines of code in my script. While the script is waiting for a response from the database, the tick function doesn't get called. In case it helps, the site is built using Drupal (with lots of customisation), and is running on a virtual dedicated Linux server on PHP 5.2 with MySQL 5.

Html.Editor() helper in ASP.NET MVC 3 does not work as expected with array in model

- by SlimShaggy

In my ASP.NET MVC 3 application I have classes like the following: public class Localization<T> { public int VersionID { get; set; } public T Value { get; set; } ... } public class Localizable<T> { public Localization<T>[] Name { get; set; } ... } Then, I have the following view: @model dynamic ... @for (int i = 0; i < VersionCount; i++) { ... @Html.Editor(string.Format("Name[{0}.Value", i)) ... } Now, when I display this view, passing a subclass of Localizable<string> as the model, the textboxes for the strings are rendered, but they are empty. If I replace @Html.Editor(string.Format("Name[{0}.Value", i)) with @InputExtensions.TextBox(Html, string.Format("Name[{0}].Value", i), Model.Name[i].Value), the textboxes are correctly filled with values from the model. However, using TextBox instead of Editor is not an option for me, because I want to use different editor templates for different types of T. So, what am I doing wrong, or is it a bug in MVC, and is there any workaround?

How to gracefully handle YouTube thumbnail broken images when videos are taken down?

- by mrjf

Our site contains some lists of YouTube videos with their thumbnails linked to the movies themselves. We fetch the thumbnail URLs from the YouTube API, and hotlink to them in situ on YouTube's servers. So our image tags look like: <img src="http://i.ytimg.com/vi/o6CHqSN7O-o/2.jpg" alt="" width="133" height="78" /> The problem is that sometimes a video gets removed -- and so does the thumbnail. We don't know when that might happen, and our thumbnails just turn into broken images. How can we handle this? There are a number of solutions: Download thumbnails and store them locally -- movie won't work, but that's ok, it will explain it was removed, and we avoid the broken image Check periodically with the API to see if the image thumbnail has changed -- if it no longer exists, substitute our own "movie removed" thumbnail. This is pretty heavy on the API calling! Use JavaScript to replace broken images (don't like this one much) Our ideal solution would be to point the img src to a location on YouTube that would display a friendly "move removed" image when a movie goes down. However, that doesn't seem to exist. Anyone else dealt with this? Thanks!

And now for a complete change of direction from C++ function pointers

- by David

I am building a part of a simulator. We are building off of a legacy simulator, but going in different direction, incorporating live bits along side of the simulated bits. The piece I am working on has to, effectively route commands from the central controller to the various bits. In the legacy code, there is a const array populated with an enumerated type. A command comes in, it is looked up in the table, then shipped off to a switch statement keyed by the enumerated type. The type enumeration has a choice VALID_BUT_NOT_SIMULATED, which is effectively a no-op from the point of the sim. I need to turn those no-ops into commands to actual other things [new simulated bits| live bits]. The new stuff and the live stuff have different interfaces than the old stuff [which makes me laugh about the shill job that it took to make it all happen, but that is a topic for a different discussion]. I like the array because it is a very apt description of the live thing this chunk is simulating [latching circuits by row and column]. I thought that I would try to replace the enumerated types in the array with pointers to functions and call them directly. This would be in lieu of the lookup+switch.

Moving checkmarks in checkbox lists after page reload - Firefox only

- by DaveS

I'm getting some strange behavior in Firefox whenever I put checkboxes inside a list (ol, ul, dl), and then dynamically insert buttons above the list. If I start with a something simple list like this: <dl class="c"> <dt><label for="a1"><input type="checkbox" id="a1" />one</label></dt> <dt><label for="a2"><input type="checkbox" id="a2" />two</label></dt> <dt><label for="a3"><input type="checkbox" id="a3" />three</label></dt> </dl> and add some jQuery like this: $(document).ready(function(){ var a = $('<button type="button">a</button>'); var b = $('<button type="button">b</button>'); $('<div/>').append(a).append(b).insertBefore($('.c')); }); ...then open it in Firefox, it looks fine at first. But check the first checkbox, reload the page, and the check-mark jumps to the second box. Reload again, and it jumps to the third. Reload yet again, and no checkboxes are left checked. If I leave out one of the buttons by dropping one of the append calls, it's fine. If I change the buttons to divs or something similar, it's fine. If I replace the dl tag with a div (and get rid of the dt tags), it's fine. But I need both buttons, and the checkboxes have to be in a list for what I'm trying to build. Does anybody know what's causing this?

Is there a way to restart a cursor? Oracle

- by Solid1Snake1

I am trying to do something such as: for(int i = 0; i<10; i++) { for(int j = 0; j<10; j++) { Blah; } } //As you can see each time that there is a different i, j starts at 0 again. Using cursors in Oracle. But if I'm correct, after I fetch all rows from a cursor, it will not restart. Is there a way to do this? Here is my sql: CREATE OR REPLACE PROCEDURE SSACHDEV.SyncTeleappWithClientinfo as teleCase NUMBER; CURSOR TeleAppCursor is Select distinct(casenbr) from TeleApp; CURSOR ClientInfoCursor is Select casenbr from clientinfo where trim(cashwithappyn) is null; BEGIN open TeleAppCursor; open ClientInfoCursor; LOOP fetch TeleAppCursor into teleCase; EXIT when TeleAppCursor%NOTFOUND; LOOP fetch ClientInfoCursor into clientCase; EXIT when ClientInfoCursor%NOTFOUND; if clientCase = teleCase then update ClientInfo set cashwithappyn = (select cashwithappyn from teleapp where casenbr = clientCase) where casenbr = clientCase; break; end if; END LOOP; END LOOP; END; I did check online and was unable to find anything on this.

Stream buffering issue

- by Kolyunya

The mod_rewrite documentation states that it is a strict requirement to disable in(out)put buffering in a rewrite program. Keeping that in mind I've written a simple program (I do know that it lacks the EOF check but this is not an issue and it saves one condition check per loop): #include <stdio.h> #include <stdlib.h> int main ( void ) { setvbuf(stdin,NULL,_IOLBF,4200); setvbuf(stdout,NULL,_IOLBF,4200); int character; while ( 42 ) { character = getchar(); if ( character == '-' ) { character = '_'; } putchar(character); } return 42 - 42; } After making some measurements I was shocked - it was over 9,000 times slower than the demo Perl script provided by the documentation: #!/usr/bin/perl $| = 1; # Turn off I/O buffering while (<STDIN>) { s/-/_/g; # Replace dashes with underscores print $_; } Now I have two related questions: Question 1. I believe that the streams may be line buffered since Apache sends a new line after each path. Am I correct? Switching my program to setvbuf(stdin,NULL,_IOLBF,4200); setvbuf(stdout,NULL,_IOLBF,4200); makes it twice as fast as Perl one. This should not hit Apache's performance, should it? Question 2. How can one write a program in C which will use unbuffered streams (like Perl one) and will perform as fast as Perl one?

Problem using find function in Matlab

- by Peter Etchells

Hi all, I have two arrays of data that I'm trying to amalgamate. One contains actual latencies from an experiment in the first column (e.g. 0.345, 0.455... never more than 3 decimal places), along with other data from that experiment. The other contains what is effectively a 'look up' list of latencies ranging from 0.001 to 0.500 in 0.001 increments, along with other pieces of data. Both data sets are X-by-Y doubles. What I'm trying to do is something like... for i = 1:length(actual_latency) row = find(predicted_data(:,1) == actual_latency(i) full_set(i,1:4) = [actual_latency(i) other_info(i) predicted_info(row,2)... predicted_info(row,3)]; end ...in order to find the relevant row in predicted_data where the look up latency corresponds to the actual latency. I then use this to created an amalgamated data set, full_set. I figured this would be really simple, but the find function keeps failing by throwing up an empty matrix when looking for an actual latency that I know is in predicted_data(:,1) (as I've double-checked during debugging). Moreover, if I replace find with a for loop to do the same job, I get a similar error. It doesn't appear to be systematic - using different participant data sets throws it up in different places. Furthermore, during debugging mode, if I use find to try and find a hard-coded value of actual_latency, it doesn't always work. Sometimes yes, sometimes no. I'm really scratching my head over this, so if anyone has any ideas about what might be going on, I'd be really grateful.

Regex to remove all but file name from links

- by Moasely

Hi, I am trying to write a regexp that removes file paths from links and images. href="path/path/file" to href="file" href="/file" to href="file" src="/path/file" to src="file" and so on... I thought that I had it working, but it messes up if there are two paths in the string it is working on. I think my expression is too greedy. It finds the very last file in the entire string. This is my code that shows the expression messing up on the test input: <script type="text/javascript" src="/javascripts/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ var s = '<a href="one/keepthis"><img src="/one/two/keep.this"></a>'; var t = s.replace(/(src|href)=("|').*\/(.*)\2/gi,"$1=$2$3$2"); alert(t); }); </script> It gives the output: <a href="keep.this"></a> The correct output should be: <a href="keepthis"><img src="keep.this"></a> Thanks for any tips!

jquery dialog calls a server side method with button parameters

- by Chiefy

Hello all, I have a gridview control with delete asp:ImageButton for each row of the grid. What I would like is for a jquery dialog to pop up when a user clicks the delete button to ask if they are sure they want to delete it. So far I have the dialog coming up just fine, Ive got buttons on that dialog and I can make the buttons call server side methods but its getting the dialog to know the ID of the row that the user has selected and then passing that to the server side code. The button in the page row is currently just an 'a' tag with the id 'dialog_link'. The jquery on the page looks like this: $("button").button(); $("#DeleteButton").click(function () { $.ajax({ type: "POST", url: "ManageUsers.aspx/DeleteUser", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { // Replace the div's content with the page method's return. $("#DeleteButton").text(msg.d); } }); }); // Dialog $('#dialog').dialog({ autoOpen: false, width: 400, modal: true, bgiframe: true }); // Dialog Link $('#dialog_link').click(function () { $('#dialog').dialog('open'); return false; }); The dialog itself is just a set of 'div' tags. Ive thought of lots of different ways of doing this (parameter passing, session variable etc...) but cant figure out how to get any of them working. Any ideas are most welcome As always, thanks in advance to those who contribute.

How can I compare the performance of log() and fp division in C++?

- by Ventzi Zhechev

Hi, I’m using a log-based class in C++ to store very small floating-point values (as the values otherwise go beyond the scope of double). As I’m performing a large number of multiplications, this has the added benefit of converting the multiplications to sums. However, at a certain point in my algorithm, I need to divide a standard double value by an integer value and than do a *= to a log-based value. I have overloaded the *= operator for my log-based class and the right-hand side value is first converted to a log-based value by running log() and than added to the left-hand side value. Thus the operations actually performed are floating-point division, log() and floating-point summation. My question whether it would be faster to first convert the denominator to a log-based value, which would replace the floating-point division with floating-point subtraction, yielding the following chain of operations: twice log(), floating-point subtraction, floating-point summation. In the end, this boils down to whether floating-point division is faster or slower than log(). I suspect that a common answer would be that this is compiler and architecture dependent, so I’ll say that I use gcc 4.2 from Apple on darwin 10.3.0. Still, I hope to get an answer with a general remark on the speed of these two operators and/or an idea on how to measure the difference myself, as there might be more going on here, e.g. executing the constructors that do the type conversion etc. Cheers!

Code Golf: Connecting the dots

- by ChristopheD

Description: The input are multiple lines (terminated by a newline) which describe a 'field'. There are 'numbers' scattered across this field: the numbers always start at 1 they follow the ordering of the natural numbers: every 'next number' is incremented with 1 every number is surrounded by (at least) one whitespace on it's left and right Task: Draw lines between these numbers in their natural order (1 -> 2 -> 3 -> ...N) with the following characteristics: replace a number with a '+' character for horizontal lines: use '-' for vertical lines: use '|' going left and down or right and up: / going left and up or right and down: \ Important note: When drawing lines of type 4 and 5 you can assume that : (given points to connect with coordinates x1, y1 and x2, y2) distance(x1,x2) == distance(y1,y2). Have a look at the examples to see where you should 'attach' the lines. It is important to follow the order in which the dots are connected (newer lines can be drawn over older lines). Sample input 1 9 10 8 7 6 5 11 13 12 3 4 14 15 16 1 2 Sample output 1 /+ / | / | +/ +--+ | +\ | \ | \+ /+ | / | /+-------------+/ +---+ / | +--+ | + | +--------------------------+ Sample input 2 4 2 3 5 6 1 8 7 Sample output 2 /+ / | / | / | /+------------------+/ +--------+\ / \ +/ +--------------------------------------+ Winner: shortest solution (by code count). Input can be read via command line.

Simply tag-based highlighting with Javascript

- by nkd

Hello, I got this code which works: <html> <head> <title>JS highlighting test</title> <script type="text/javascript"> function highlight() { var t = document.getElementById('highlight').innerHTML; t = t.replace(/(if|switch|for|while)\s*(\()/gi, "<b>$1</b>$2"); document.getElementById('highlight').innerHTML = t; } </script> </head> <body onload="javascript:highlight();"> <pre id="highlight"> 1 if(foo) { 2 bar(); 3 } 4 3 while(--baz) { 5 oof(); 6 } </pre> </body> </html> I would like to have it for all <pre> tags instead of just one with some specific and unique id as it works now. The best would be to have an combination of a specific tag with a specific id. Is it possible to extend the small JS function above to work this way (using some document.getElementsByTag(tag).getElementsById(id).innerHTML or something alike (I don't know what exactly suites the need) in a loop? I tried myself but with no real success. I need only as simple solution as possible, nothing really special. Thank you for your ideas. -- nkd

Select All in Javascript (Firefox extension) not working right

- by leezer3

I'm having some problems with a select all/ none function. (I didn't write it, I'm trying to fix it!) It currently looks like this: rsfindmod.SelAll = function(){ document.getElementById("ListBox").selectAll(); document.getElementById("ListBox").focus(); } It's being used on a dynamically generated set of links, so there's no set number of items in this listbox. This seems to work most of the time, but randomly it only selects those which are visible at the time. Scrolling the list or hitting the button again seems to normally make it work as expected. My first (Obvious?) thought was to replace the function entirely with the one from this link for testing: http://viralpatel.net/blogs/2009/06/listbox-select-all-move-left-right-up-down-javascript.html Trouble is that I can't get this one to work whatsoever! This gives me the error that listbox.options is not defined Any thoughts please? I'm by no means certain whether it's the original function at fault, or something in the generation of this listbox.

Error while setting UserAcces permission for WebForms?

- by ksg

I've created a class named BaseClass.cs and I've written a function in its constructor. Here's how it looks public class BasePage:Page { public BasePage() { setUserPermission(); } private void setUserPermission() { String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery; string strulr = strPathAndQuery.Replace("/SGERP/", "../"); Session["Url"] = strulr; GEN_FORMS clsForm = new GEN_FORMS(); clsForm.Form_Logical_Name = Session["Url"].ToString(); clsForm.User_ID = Convert.ToInt32(Session["User_ID"]); DataSet dsPermission = clsForm.RETREIVE_BUTTON_PERMISSIONS(); if (dsPermission.Tables.Count > 0) { if (dsPermission.Tables[1].Rows.Count > 0) { Can_Add = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Add"].ToString()); Can_Delete = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Delete"].ToString()); Can_Edit = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Edit"].ToString()); Can_Print = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Print"].ToString()); Can_View = Convert.ToBoolean(dsPermission.Tables[1].Rows[0]["Can_Print"].ToString()); } } } } I've inherited this class on my webform so that when the page loads, the setUserPermission function is executed. My webpage looks like this public partial class Setting_CompanyDetails : BasePage My problem is that I cannot access Session["Url"] in my BasePage. I'm getting the following error Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration. How can I solve this issue? Is this the right way to set UserPermission access?

is_dir does not recognize folders

- by Rakoon

Hi I am trying to make a function that scans a folder for subfolders and then returns a numeric array with the names of those folders. This is the code i use for testing. Once i get it to print out the folder names and not just "." and ".." for present and above folder all will be well, and I can finish the function. <?php function super_l_getthemes($dir="themes") { if ($handle = opendir($dir)) { echo "Handle: {$handle}\n"; echo "Files:\n"; while (false !== ($file = readdir($handle))) { echo "{$file}<br>"; } closedir($handle); } ?> The above code works fine, and prints out all the contents of the folder: files, subfolders and the "." and ".." but if i replace: while (false !== ($file = readdir($handle))) { echo "{$file}<br>"; } with: while (false !== ($file = readdir($handle))) { if(file_exists($file) && is_dir($file)){echo "{$file}";} } The function only prints "." and ".." , not the two folder names that I'd like it to print. Any help is appreciated.

Override one css class with another?

- by user246114

Hi, I have a list, with an li style defined. I want to replace the style of an individual element, but it doesn't seem to have any visual effect. Example: .myList li { background-color: yellow; } .foo { background-color: green; } <ul class='myList'> <li>Hello</li> </ul> When I add an item to the list, it has the .myList li style applied properly. I try now to remove all styles and apply the foo style to a single item (using jquery): $(item).removeClass(); $(item).addClass("foo"); the item does not change color to green though, but this reports the class is set to 'foo': alert($(item).attr('class')); so I guess I'm not understanding css rules here, looks like the li class definition is just overriding whatever else I do, however I want the reverse to be true, I want to override the li style definition with foo. How do we do this? Thanks

C# form - checkboxes do not respond to plus/minus keys - easy workaround?

- by Scott

On forms created with pre dotNET VB and C++ (MFC), a checkbox control responded to the plus/minus key without custom programming. When focus was on the checbox control, pressing PLUS would check the box, no matter what the previous state (checked/unchecked), while pressing MINUS would uncheck it, no matter the previous state. C# winform checkboxes do not seem to exhibit this behavior. Said behavior was very, very handy for automation, whereby the automating program would set focus to a checkbox control and issue a PLUS or MINUS to check or uncheck it. Without this capability, that cannot be done, as the automation program (at least the one I am using) is unable to query the current state of the checkbox (so it can decide whether to issue a SPACE key to toggle the state to the desired one). I've gone over the properties of a checkbox in the Visual Studio 2008 IDE and could not find anything that would restore/enable response to PLUS/MINUS. Since I am in control of the sourcecode for the WinForms in question, I could replace all checkbox controls with a custom checkbox control, but blech, I'd like to avoid that - heck, I don't think I could even consider that given the amount of refactoring that would need to be done. So the bottom line is: does anyone know of a way to get this behavior back more easily than a coding change?

What can I do to fix this problem? I though that using events: output would place the text in that location but it does not seem to be working. Thank you all kindly in advance for any comments or answers!

post values to external page explicitly PHP

- by JPro

Hi, I want to post values to a page through a hyperlink in another page. Is it possible to do that? Let's say I have a page results.php which has the starting line, <?php if(isset($_POST['posted_value'])) { echo "expected value"; // do something with the data } else { echo "no the value expected"; } If from another page say link.php I place a hyperlink like this: <a href="results.php?posted_value=1"> , will this be accepetd by the results page? If instead if I replace the above starting line with if(isset($_REQUEST['posted_value'])), will this work? I believe the above hyperlink evaluates to GET, but since the only visibility difference between GET and POST that is you can see parameters in the address bar with GET But, is there any other way to place a hyperlink which can post values to a page? or can we use jquery in the place of hyperlink to POST the values? Can anyone please suggest me something on this please? Thanks.

How to remove background of a image and copy into another?

- by Gustavo Pinent

I'm researching about captchas. In this idea, the task is: create a image from a JPEG and remove the white background, than create another image from another JPEG, than create the final image by adding the second as a background, and copying the first one over this background preserving the transparent area created, of course. Here is the code: header("Content-Type: image/jpeg"); $nFundo = rand(0,4); $Dirs = array(rand(0,7), rand(0,7), rand(0,7), rand(0,7)); // Will be four times all $_SESSION["form_captcha"] = $Dirs; $image = ImageCreatetruecolor(320, 80); ImageAlphaBlending($image, FALSE); ImageSaveAlpha($image, TRUE); $image_seta = ImageCreateFromJPEG("_captcha-seta.jpg"); // Image do copy over $image_fundo = ImageCreateFromJPEG("_captcha-fundo-".$nFundo.".jpg"); // Image to make the background for($i=0; $i<4; $i++){ ImageCopy($image, $image_fundo, $i*80, 0, 0, 0, 80, 80); } // So far so good, a background with a pattern repeated four times $color_white = ImageColorAllocate($image_seta, 255, 255, 255); ImageColorTransparent($image_seta, $color_white); ImageSaveAlpha($image_seta, TRUE); for($i=0; $i<4; $i++){ $image_seta_rot = imageRotate($image_seta, $Dirs[$i]*45, $color_white); ImageCopyResampled($image, $image_seta_rot, $i*80, 0, 0, 0, 80, 80, 80, 80); // Try } echo(imagejpeg($image)); imagedestroy($image); I tried to replace $image_seta_rot by $image_seta ("Try" line) to see if the rotation is the problem, but even without rotation, the white wasn't removed and the image just "erase" the background created before. So the copy is failing or the white were never removed... I may create a PNG with transparent background, but will be interesting to learn how to make it dynamically, don't you think? Any ideas?

Substitute User Controls on Failure

- by Brian

Recently, I had a user control I was developing throw an exception. I know what caused the exception, but this issue got me thinking. If I have a user control throw an exception for whatever reason and I wish to replace that usercontrol with something else (e.g. an error saying, "Sorry, this part of the page broke.") and perhaps log the error, what would be a good way to do it that could be done independently of what the user control is or does (i.e. I'm not saying what the user control does/is, because I want an answer where that is irrelevant). Code sample: <asp:TableRow VerticalAlign="Top" HorizontalAlign="Left"> <asp:TableCell> <UR:MyUserControl ID="MyUserControl3" runat="server" FormatString="<%$ AppSettings:RVUC %>" ConnectionString="<%$ ConnectionStrings:WPDBC %>" Title="CO" /> </asp:TableCell> <asp:TableCell> <UR:MyUserControl ID="MyUserControl4" runat="server" FormatString="<%$ AppSettings:RVUA %>" ConnectionString="<%$ ConnectionStrings:WPDBA %>" Title="IEAO" /> </asp:TableCell> </asp:TableRow>

jQuery - Can someone help stitching jQuery code with .ajaxComplete()?

- by Kenny Bones

Hi, so I've got this content loader that replaces content within a div with content from a separate page. But the content that arrives contains a menu that uses jQuery and this is not working. Someone told me I need to reinitialize the code. But how do I do that? I've looked into .ajaxComplete(), but I don't really get how I'm supposed to stitch that together with my existing code? $('.dynload').live('click', function(){ var toLoad = $(this).attr('href')+' #content'; $('#content').fadeOut('fast',loadContent); $('#ajaxloader').fadeIn('normal'); function loadContent() { $('#content').load(toLoad,'',showNewContent()) } function showNewContent() { $('#content').fadeIn('fast',hideLoader()); //Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); } function hideLoader() { $('#ajaxloader').fadeOut('normal'); } return false; }); This is the code I'm using for the jQuery menu: $().ready(function() { $('#kontrollpanel .slidepanels').kwicks({ min : 42, spacing : 3, isVertical : true, sticky : true, event : 'click' }); }); Also, notice how I try to call Cufon as well within the first function? That doesn't really work either, could that be reinitialized as well? Would really appreciate any help at all..

images not showing up in tab body on class change in IE

- by user347352

I can't get any images to show up when I'm using IE with these makeshift tabs I made, everything shows up and space is allocated for the image but the image doesn't show up when I change the class. I'm using the css property visiblity to make it work. function findJournalId(d){ var parent=jQuery(d).parent(); while(!parent.hasClass("journal-content-article")) { parent=parent.parent(); } var parentID=parent.attr("id"); var ret="#"+parentID.replace(/(:|\.)/g,"\\$1"); return ret; };/*]]>*/ </script> </head> <body> <div class="journal-content-article" id="article_66742_350610_1.0"> <ul id="newsTabs"> <li class="tab"> <a class="1">first tab</a> </li> <li class="tab"> <a class="2">second tab</a> </li> <li class="tab"> <a class="3">third tab</a> </li> </ul> <div class="news 1"> This is the first portlet <img width="200px" src="banner head.jpg" /> </div> <div class="news 2"> what up 2 </div> <div class="news 3"> hello 3 </div>
