how to pass in dynamic data to decorators

- by steve

Hi, I am trying to write a base crud controller class that does the following: class BaseCrudController: model = "" field_validation = {} template_dir = "" @expose(self.template_dir) def new(self, *args, **kwargs) .... @validate(self.field_validation, error_handler=new) @expose() def post(self, *args, **kwargs): ... My intent is to have my controllers extend this base class, set the model, field_validation, and template locations, and am ready to go. Unfortunately, decorators (to my understanding), are interpreted when the function is defined. Hence it won't have access to instance's value. Is there a way to pass in dynamic data or values from the sub class? If not, I guess I could use override_template as a workaround to expose and set the template within the controller action. How would I go about validating the form within the controller action? Thanks, Steve

What is the proper way to specify a path to 'app' in a Rails plugin?

- by Brian Deterling

This question came about because the cells gem specifies template directories using File.join('app','cells'). That works fine until you run Rails as a daemon (scripts/server -d). The daemon switches directories to / which leaves the cells template paths pointing to the wrong absolute path. My solution was to set the default paths to File.join(RAILS_ROOT, 'app', 'cells'). This works in Rails, but the unit tests for the plugin fail because RAILS_ROOT isn't defined. Using File.join(File.dirname(__FILE__),'..' ... also works but requires about 6 levels of '..' which seems wrong. So my question is what is the proper way to specify the path to a directory under 'app' in a Rails plugin? Or is there something else wrong that would cause daemonizing Rails to fail to find the relative paths?

Moving ordered elements and adding arbitrary text in Deliverance

- by Jon Hadley

Using the following XPath derived rule, I am able to select a list of events from a Plone site (similar to Plone Community events) and display them in my Deliverance themed site: <replace content="//*[@id='parent-fieldname-title' or @class='explain' or @id='parent-fieldname-location' or @id='parent-fieldname-text']" theme="#center-content-to-replace-one" /> However, two separate, but related, problems now rear their heads. I can't work out how to: Re-order elements within the replaced theme, such as moving images originally held within #parent-fieldname-text to before #parent-fieldname-title Put arbitrary text before elements. Such as 'Page Title:' before #parent-fieldname-title I could do both if I was just dealing with one record, as place holders(1) or text before place holders(2) could be specified in the template - but I can't see a away for that template behaviour to repeat across multiple items in one page. (if that is indeed the solution) Is this a job for pyQuery?

Why doesn't this code work correctly?

- by MisterSir

I'm working on a website that displays galleries, using jCarousel. But no matter what I try, I can't get it to work, and I need to finish this by today. I have a very urgent schedule. My code basically takes image URLs from a database and sends them to AJAX, which passes it to jCarousel which makes the gallery. But there are a few problems: It doesn't display correctly! I can only get the last item pulled from the database, and it displays on the bottom-most row. After the item pulled from the database is displayed, the first time I click on "prev" there's no scroll effect, and the item just disappears! Only if I click on "next" 2-3 times there's a scroll effect and the item remains visible. My items are always displayed at the end of the carousel! This is urgent.. Please help me fix this. about.html: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-us"> <head> <script type="text/javascript" src="jquery-1.4.4.min.js"></script> <script type="text/javascript" src="/lib/jquery.jcarousel.min.js"></script> <link rel="stylesheet" type="text/css" href="/skins/tango/skin.css" />  <script type="text/javascript"> jQuery.easing['BounceEaseOut'] = function(p, t, b, c, d) { if ((t/=d) < (1/2.75)) { return c*(7.5625*t*t) + b; } else if (t < (2/2.75)) { return c*(7.5625*(t-=(1.5/2.75))*t + .75) + b; } else if (t < (2.5/2.75)) { return c*(7.5625*(t-=(2.25/2.75))*t + .9375) + b; } else { return c*(7.5625*(t-=(2.625/2.75))*t + .984375) + b; } }; function mycarousel_initCallback(carousel) { jQuery('#mycarousel-next').bind('click', function() { carousel.next(); return false; }); jQuery('#mycarousel-prev').bind('click', function() { carousel.prev(); return false; }); }; jQuery(document).ready(function() { jQuery('#mycarousel').jcarousel({ easing: 'BounceEaseOut', wrap: "first", initCallback: mycarousel_initCallback, animation: 1000, scroll: 3, visible: 3, buttonNextHTML: null, buttonPrevHTML: null }); jQuery('#mycarousel2').jcarousel({ easing: 'BounceEaseOut', animation: 1000, wrap: "first", initCallback: mycarousel_initCallback, scroll: 3, visible: 3, buttonNextHTML: null, buttonPrevHTML: null }); jQuery('#mycarousel3').jcarousel({ easing: 'BounceEaseOut', animation: 1000, scroll: 3, wrap: "first", initCallback: mycarousel_initCallback, visible: 3, buttonNextHTML: null, buttonPrevHTML: null }); }); var prevButton = null; function getObject(b, el) { var currbutton = b; var http; var url = "about.php"; var parameters = "d=carousel&cat=" + currbutton; try { http = new XMLHttpRequest(); } catch(e) { try { http = new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) { http = new ActiveXObject("Microsoft.XMLHTTP"); } } function getServer() { if (http.readyState == 4) { var i = 0; var liArr = http.responseText; var built = liArr.split(", "); var li = document.createElement("li"); var ul1 = document.getElementById("mycarousel"); var ul2 = document.getElementById("mycarousel2"); var ul3 = document.getElementById("mycarousel3"); if (el != prevButton) { prevButton = el; while (ul1.hasChildNodes() ) {ul1.removeChild(ul1.lastChild);} while (ul2.hasChildNodes() ) {ul2.removeChild(ul2.lastChild);} while (ul3.hasChildNodes() ) {ul3.removeChild(ul3.lastChild);} } else return 0; while (i < (built.length) / 3) { li.innerHTML = built[i]; ul1.appendChild(li); i++; } while (i < ((built.length) / 3)*2) { li.innerHTML = built[i]; ul2.appendChild(li); i++; } while (i < (built.length)) { li.innerHTML = built[i]; ul3.appendChild(li); i++; } } } http.open("POST", url, true); http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.setRequestHeader("Content-length", parameters.length); http.setRequestHeader("Connection", "close"); http.onreadystatechange = getServer; http.send(parameters); } </script> </head> <body> <span id="hidden"> </span> <div id="wrapper"> <div id="side"> <form name="cats"> <input type="button" value="Hats" onclick="getObject('hats', this);"/><br /> <input type="button" value="Pants" onclick="getObject('pants', this);"/><br /> <input type="button" value="Shirts" onclick="getObject('shirts', this);"/><br /> </form> </div> <div id="carousel"> <ul id="mycarousel" class="jcarousel-skin-tango"> </ul> <ul id="mycarousel2" class="jcarousel-skin-tango"> </ul> <ul id="mycarousel3" class="jcarousel-skin-tango"> </ul> <input type="button" id="mycarousel-prev" value="prev" /> <input type="button" id="mycarousel-next" value="next" /> </div> </div> </body> </html> I commented the CSS because I thought it was giving me trouble, but honestly I have no idea what the hell's going on with jCarousel. about.php: <?php echo "<img width='75' height='75' src='http://static.flickr.com/66/199481236_dc98b5abb3_s.jpg' />, hi, hi, hi, hi, hi, hi, hi, hi"; ?> Also, even if there are no other items than what is displayed, I'm still able to scroll back, but not forward, assumingly because my item is always placed at the end of the carousel. I know it looks like a lot of code but it's really not! My formatting takes a lot of lines, the commented CSS takes a lot, and a lot of the code is HTML and jCarousel configuration, and there's also the BounceEasing effect which takes a few lines. There's not much actual code! So as I said, this is urgent and I need this fixed. But I can't get it to work. Please help me! Thanks for your time! EDIT: I changed the code a bit, but it still does not work. I really need help on this one!! EDIT: I added document.createElement("li"); to each while loop. Now all my items are displayed, but they are displayed vertically and not horizontally on each row. Other than that all other problems are the same. EDIT: Oh and also, in the row my image displays, only the image is there. Maybe jCarousel doesn't accept img and text, I don't know.

Implement the Combine function using templates

- by gkid123

any idea on how to do it for template? thanks Implement the Combine function using templates. The Combine fn applies a function of two arguments cumulatively to the items of an STL container, from begin() to end(), so as to reduce the sequence to a single value. For example, Combine(<list containing 6,3,1,9,7>, std::plus<int>()) should calculate ((((6+3)+1)+9)+7). class NotEnoughElements {}; template <typename Container, typename Function> typename Container::value_type Combine(const Container& c, Function fn) throw (NotEnoughElements) { your code goes here }

Convert string to variable in Javascript

- by waiwai933

Is there any way to convert a string to a variable in Javascript? Right now, what I have is a script that updates data based on the values of the select box: <script type="text/javascript"> var a = new Array(); a[0] = 'Name'; a[1] = 'Description'; var b = new Array(); b[0] = 'Name 2'; b[1] = 'Description 2'; function changeSystem(){ var selectedAccount=document.getElementById('selected_option').value; document.getElementById('name').innerHTML = selectedAccount[0]; document.getElementById('description').innerHTML = selectedAccount[1]; } </script> <form method="POST"> <select onchange="changeSystem()" id="selected_option"> <option>A</option> <option>B</option> </select> </form> <span id="name"></span><br> <span id="description"></span><br> selectedAccount is the string of the chosen element in <select>. However, for it to access the array, it needs to be a variable, i.e. a[0] instead of 'a'[0]. What solutions are there to this?

Convert InputStream to String with encoding given in stream data

- by Quentin

Hi, My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document. From this InputStream, I want to have all document in a String. To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding. It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error. Any idea, how to do it ? public static String streamToString(final InputStream is) { String result = null; if (is != null) { BufferedInputStream bis = new BufferedInputStream(is); bis.mark(Integer.MAX_VALUE); final StringBuilder stringBuilder = new StringBuilder(); try { // stream reader that handle encoding final InputStreamReader readerForEncoding = new InputStreamReader(bis, "UTF-8"); final BufferedReader bufferedReaderForEncoding = new BufferedReader(readerForEncoding); String encoding = extractEncodingFromStream(bufferedReaderForEncoding); if (encoding == null) { encoding = DEFAULT_ENCODING; } // stream reader that handle encoding bis.reset(); final InputStreamReader readerForContent = new InputStreamReader(bis, encoding); final BufferedReader bufferedReaderForContent = new BufferedReader(readerForContent); String line = bufferedReaderForContent.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReaderForContent.readLine(); } bufferedReaderForContent.close(); bufferedReaderForEncoding.close(); } catch (IOException e) { // reset string builder stringBuilder.delete(0, stringBuilder.length()); } result = stringBuilder.toString(); }else { result = null; } return result; } Regards, Quentin

Click outside menu to close in jquery

- by George

So I have a drop-down menu that shows on a click, as per business requirements. The menu becomes hidden again after you mouse away from it. But now I am being asked to have it stay in place until user clicks anywhere on the document. How can this be accomplished? This is a simplified version of what I have now: $(document).ready(function() { $("ul.opMenu li").click(function(){ $('#MainOptSubMenu',this).css('visibility', 'visible'); }); $("ul.opMenu li").mouseleave(function(){ $('#MainOptSubMenu',this).css('visibility', 'hidden'); }); }); <ul class="opMenu"> <li id="footwo" class=""> <span id="optImg" style="display: inline-block;"> <img src="http://localhost.vmsinfo.com:8002/insight/images/options-hover2.gif"/> </span> <ul id="MainOptSubMenu" style="visibility: hidden; top: 25px; border-top: 0px solid rgb(217, 228, 250); background-color: rgb(217, 228, 250); padding-bottom: 15px;"> <li>some</li> <li>nav</li> <li>links</li> </ul> </li> </ul> I tried something like this $('document[id!=MainOptSubMenu]').click(function() thinking it would trigger on anything that wasnt the menu, but it didnt work.

How to start a ColorAnimation from a MultiTrigger in a ControlTemplate ?

- by banzai

Hi all I have the following ControlTemplate for a WPF TabItem: <ControlTemplate x:Key="DefaultTabItemTemplate" TargetType="{x:Type TabItem}"> <ControlTemplate.Resources> <SolidColorBrush x:Key="UnselectedForegroundBrush" Color="#414141" />  <SolidColorBrush x:Key="SelectedForegroundBrush" Color="#457581" />  <SolidColorBrush x:Key="MouseOverTextBrush" x:Name="local_MouseOverTextBrush" Color="#FFF2F2F2"/> </ControlTemplate.Resources> <Grid> <Border Name="Border" MinHeight="30" Margin="0,0,0,-1" Background="{DynamicResource TabControlBackgroundBrush}" BorderBrush="{DynamicResource ndt_DisabledForegroundBrush}" BorderThickness="1,1,1,1" CornerRadius="0,0,0,0" > <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" TextElement.FontStretch="UltraExpanded" TextElement.FontWeight="UltraBlack" ContentSource="Header" Margin="12,2,12,2" RecognizesAccessKey="True" /> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="Panel.ZIndex" Value="2" /> <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_TabControlBackgroundBrush}" /> <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" /> <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{StaticResource SelectedForegroundBrush}" /> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_DisabledBackgroundBrush}" /> <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{DynamicResource ndt_DarkGray}" /> <Setter Property="Foreground" Value="{DynamicResource ndt_DisabledForegroundBrush}" /> </Trigger> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="IsMouseOver" Value="True" /> <Condition Property="IsSelected" Value="False" /> </MultiTrigger.Conditions> <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_NavigationAreaBrush}" /> <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{DynamicResource MouseOverTextBrush}" /> </MultiTrigger> </ControlTemplate.Triggers> </ControlTemplate> Everything works fine so far. The MultiTrigger at the end of the template defines a mouse over effect for not selected TabItems. Now I thought the change in color for this mouse over effect looks a bit brash so let´s animate it with a ColorAnimation. But don´t count the chickens before they hatch - everything I tried didn´t work. Maybe I oversee the obvious - but how to achieve this feat ? Thanks in advance banzai

Rotate a drawed rectangle in flex

i wrote the following code for draw a rotate rectangle var s:UIComponent = new UIComponent(); s.graphics.lineStyle(1, 0x0000FF); s.graphics.drawRect(50, 50, 200, 200); s.rotation = 30; template.addChild(s); where template is a canvas. Its rotate nicely but the problem is the position is not in right place. i.e. it is not in (50,50) after rotate. How can i solve this problem? Thanks in advance.

Manually filling opcode cache for entire app using apc_compile_file, then switching to new release.

- by Ben

Does anyone have a great system, or any ideas, for doing as the title says? I want to switch production version of web app-- written in PHP and served by Apache-- from release 1234 to release 1235, but before that happens, have all files already in the opcode cache (APC). Then after the switch, remove the old cache entries for files from release 1234. As far as I can think of there are three easy ways of atomically switching from one version to the next. Have a symbolic link, for example /live, that is always the document root but is changed to point from one version to the next. Similarly, have a directory /live that is always the document root, but use mv live oldversion && mv newversion live to switch to new version. Edit apache configuration to change the document root to newversion, then restart apache. I think it is preferable not to have to do 3, but I can't think of anyway to precompile all php files AND use 1 or 2 to switch release. So can someone either convince me its okay to rely on option 3, or tell me how to work with 1 or 2, or reveal some other option I am not thinking of?

IE8 claims my page has an error, firefox doesn't, and I can't find any error. Help!

- by Bears will eat you

This is something of a follow-up question to my question here. You can find the HTML source in a text file here. When I load that page in IE8, I get the "Done, but with errors on page." message in my status bar. The detail view shows Expected identifier sms Line: 147 Code: 0 Char: 67 and I see absolutely no problems anywhere near there. In IE8, the page is still behaving erratically w/r/t the randomly losing focus as mentioned in my other question. When I load the same exact page in Firefox (using Firebug) the console shows no errors and the page works perfectly. Any thoughts on what's going on here? This is driving me nuts and making me want to give up on even trying to write an IE friendly page. Edit: Thanks for all the comments! This page is written as a JSP, so I edit in Eclipse. I found an Eclipse warning about the onblur event for the username field. I switched it from onblur="alert(document.activeElement + ' class:' + document.activeElement.class)" to onblur="alert(document.activeElement)" and that made the bizarre IE page error vanish. I had been trying to give more info (namely, its CSS class) about specifically which element is stealing focus - to my own detriment, apparently, since Javascript was interpreting the '.class' part in the Java(script) sense. And, no, the page doesn't validate. But the errors were mostly/all ones that just didn't make sense, such as Line 14, Column 41: Attribute "LANGUAGE" is not a valid attribute. Did you mean "language"? to which I say, WTF?! But I'm still stuck trying to figure out why, as I enter text in the username & password fields, focus randomly switches to a div (working on figuring out which div currently). Edit 2: It's the div between the two "global nav" comments, at the very top of the body. Still no idea why it's happening, though.

Formvalidator from the iframe.

'<li>' + errors.uniq().join("<li>") : ''; } It works fine, now I have an Iframe in my document, and that I frame contains the form to validate. What will be the best practice to change this function in such a way that it can validate document forms and iframe from simeltaniously. Thanks

CREATE TABLE IF NOT EXISTS `pages` ( page-id mediumint(8) unsigned NOT NULL AUTO_INCREMENT, page-left mediumint(8) unsigned NOT NULL, page-right smallint(8) unsigned NOT NULL, page-title text NOT NULL, page-content text NOT NULL, page-time int(11) unsigned NOT NULL, page-slug text NOT NULL, page-template text NOT NULL, page-parent mediumint(8) unsigned NOT NULL, page-type text NOT NULL, PRIMARY KEY (page-id) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 ; INSERT INTO pages (page-id, page-left, page-right, page-title, page-content, page-time, page-slug, page-template, page-parent, page-type) VALUES (17, 1, 6, '1', '', 0, 'PARENT', '', 0, ''), (18, 2, 5, '2', '', 0, 'SUB', '', 17, ''), (19, 3, 4, '3', '', 0, 'SUB-SUB', '', 18, ''), (20, 7, 8, '5', '', 0, 'TEST', '', 0, ''); As example how would I move TEST up above PARENT and say move SUB down below SUB-SUB by playing with the page-left/page-right IDs? Code is not required just help with the SQL concept or math for it, would help me understand how to move it better...

Is there a way to parse XML via SAX/DOM with line numbers available per node.

- by Chris

I already have written a DOM parser for a large XML document format that contains a number of items that can be used to automatically generate Java code. This is limited to small expressions that are then merged into a dynamically generated Java source file. So far - so good. Everything works. BUT - I wish to be able to embed the line number of the XML node where the Java code was included from (so that if the configuration contains uncompilable code, each method will have a pointer to the source XML document and the line number for ease of debugging). I don't require the line number at parse-time and I don't need to validate the XML Source Document and throw an error at a particular line number. I need to be able to access the line number for each node and attribute in my DOM or per SAX event. Any suggestions on how I might be able to achieve this? P.S. Also, I read the StAX has a method to obtain line number whilst parsing, but ideally I would like to achieve the same result with regular SAX/DOM processing in Java 4/5 rather than become a Java 6+ application or take on extra .jar files.

Combining regroup with get_foo_display in Django templates

- by shacker

I'm using the regroup template tag to group queryset output on a Choices field. In the model: RESOURCE_TYPES = ( ('tut','External tutorial'), ('read','Additional reading'), ('org','Company or organization'), ) restype = models.CharField('Resource type',max_length=6,choices=RESOURCE_TYPES) in the view: resources = Resource.objects.filter(tutorial=tutorial) in the template: {% regroup resources by restype as resource_list %} {% for type in resource_list %} <h3>{{type.grouper}}</h3> So type.grouper renders as 'tut' or 'org' on the page, rather than the long form. Normally you would use the get_foo_display syntax to get at the value of the choice, rather than the key. But the value doesn't seem to be available after going through regroup. There's no way I can find to use get_foo_display on {{type.grouper}}. It makes sense when you think about it, but what's the workaround? Thanks.

Google AJAX Transliteration API :- How do i translate many elements in page to some language at one

- by Nitesh Panchal

Hello, I have many elements on page and all of which i want to translate to some language. The language is not the same for all fields, that is, for 1st field it may be fr and for third field it may be en then again for 7th field it may be pa. Basically i wrote the code and it's working :- <script type="text/javascript"> //<![CDATA[ google.load("language", "1"); window.onload = function(){ var elemPostTitles = document.getElementsByTagName("h4"); var flag = true; for(var i = 0 ; i < elemPostTitles.length ; i++){ while(flag == false){ } var postTitleElem = elemPostTitles[i]; var postContentElem = document.getElementById("postContent_" + i); var postTitle = postTitleElem.innerHTML; var postContent = postContentElem.innerHTML; var languageCode = document.getElementById("languageCode_" + i).value; google.language.detect(postTitle, function(result) { if (!result.error && result.language) { google.language.translate(postTitle, result.language, languageCode, function(result) { flag = true; if (result.translation) { postTitleElem.innerHTML = result.translation; } }); } }); flag = false; } As you can see, what i am trying to do is restrict the loop from traversing until the result of previous ajax call is receieved. If i don't do this only the last field gets translated. My code works nicely, but because of the infinite loop, i keep getting errors from Mozilla to "stop executing scripts". How do i get rid of this? Also, is my approach correct? Or some inbuilt function is available which can ease my task? Thanks in advance :)

How can I get contentWindow for an Object element in IE7

- by Scott Leis

I have a HTML object element like this: <object title="Search results as XML" standby="Loading XML document..." type="text/xml" data="/__CA25761100195585.nsf/WebPrintListingXML?OpenAgent&date1=01/06/2009" width="100%" height="100%" border="0" name="resultIFrame" id="resultIFrame" Error: could not embed search results. </object I also have this javascript function (alert() calls added for debugging): function getFrameByName(fParent,fName) { var fArray=fParent.frames; if (!fName) return; if (fArray) { if (fArray.length) { for (var i=0; i<fArray.length; i++) { alert('loop '+i); if (fArray[i]) { if (fArray[i].name==fName) return fArray[i]; } } } } var tmp=document.getElementsByName(fName); if (tmp[0]) { alert('returning '+tmp[0]); if (!(tmp[0].contentWindow)) alert('contentWindow is null'); return tmp[0].contentWindow; } } And finally, this button is meant to print the content of the Object element: <input type="button" value="Print" name="printBtn" onclick="getFrameByName(window,'resultIFrame').print();" The button works perfectly in Firefox. Opera is good enough, though it prints the main document instead of just the object. IE7 gives the following error details: Line: 57 Char: 1 Error: 'undefined' is null or not an object Line 57 is where the button's "input" tag starts in the HTML source. Thanks to the alert('contentWindow is null') call in the JS function, I know that the object I'm getting in IE has no contentWindow property. I have tried changing the object tag to an iframe tag. This changes the JS behaviour, but causes other issues such as the height attribute being ignored and the content not displaying. Sticking with an object tag, how can I get this Object's window in IE7?

JQuery set img src depending on where you click

- by Anna

Hello ! I used javascript for loading a picture on my website depending on which "small" photos in ul you clicked... I had something like that : <script type="text/javascript"> function viewImage(src, legende) { document.getElementById("imageBig").src = "images/photos/"+src; document.getElementById("legend").innerHTML = legende; } </script> and in html simply : things like that : <li><a href="#centre" onclick="javascript:viewImage('flute.jpg','La Reine de la Nuit au Comedia')"><img src="images/photos/carre-09.jpg" alt="" /></a> <a href="#centre" onclick="javascript:viewImage('perichole.jpg','Manuelita - <em>La Périchole</em> à l’Opéra Comique')"><img src="images/photos/carre-03.jpg" alt="" /></a></li> <li><a href="#centre" onclick="javascript:viewImage('12.png','Récital à Carnac, septembre 2008')"><img src="images/photos/carre-12.jpg" alt="Marion Baglan Carnac Ré" /></a> <a href="#centre" onclick="javascript:viewImage('01.jpg','')"><img src="images/photos/carre-01.jpg" alt="" /></a></li> so you see, I could, depending on which small photos in the unordered list you clicked, load some particular photos, by passing the src string in argument... but I decided to use Jquery to get some fade-in effect. But I can't find a way to pass an argument that would tell my JQuery function which photo to load depending on where I clicked... stuck here : $(document).ready(function(){ $('#ulPhotos').click(function() { var newSrc= $('#imageBig').attr("src", "images/photos/11.jpg"); }); }); I don't want the 11.jpg to be hardcoded, I need to pass it through argument when I click on a special li element in my ul element of id #ulPhotos... I hope I'm clear enough sorry !
