  • Applying powershell outside IT Management.

    - by Tormod
    Hi. We have a flexible process control system by which automation engineers configure up large application comprising thousands of small logical units that are parameterized and integrated into the control flow. There are many tasks that are repetitive on the granular level, and there are a multitude of proprietary productivity tools that have been made to meet this demand. We have different business segments, and the automation engineers vary across the board in skill sets and interests. Fancy GUI and usability versus flexibility is a common discussion. At first glance, powershell seems to be a sensible platform to implement such tooling and which also would be a advantageous cross-over skill to manage the IT aspects of the system setup and deployment as a whole. This should allow the script savvy their desired flexibility (they are already a scripting crowd) and the GUI dependant could still get their desired GUI underpinned by powershell. But I can't seem to find many people/groups who have tried to use the scriptability and object passing of powershell extensively to accommodate a heterogeneous user community outside the realm of IT management. Do anybody have any tips or word of caution? Am I missing something obvious as to why this shouldn't be done? Shouldn't powershell be taking over the world? ;-)

  • Dealloc'd Predicate crashing iPhone App!

    - by DVG
    To preface, this is a follow up to an inquiry made a few days ago: http://stackoverflow.com/questions/2981803/iphone-app-crashes-when-merging-managed-object-contexts Short Version: EXC_BAD_ACCESS is crashing my app, and zombie-mode revealed the culprit to be my predicate embedded within the fetch request embedded in my Fetched Results Controller. How does an object within an object get released without an explicit command to do so? Long Version: Application Structure Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller When a row gets clicked on the Platforms view, it sets an instance variable in Games View for that platform, then the Games Fetched Results Controller builds a fetch request in the normal way: - (NSFetchedResultsController *)fetchedResultsController{ if (fetchedResultsController != nil) { return fetchedResultsController; } //build the fetch request for Games NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Game" inManagedObjectContext:context]; [request setEntity:entity]; //predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"platform == %@", selectedPlatform]; [request setPredicate:predicate]; //sort based on name NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; //fetch and build fetched results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [sortDescriptor release]; [sortDescriptors release]; [predicate release]; [request release]; [aFetchedResultsController release]; return fetchedResultsController; } At the end of this method, the fetchedResultsController's _fetch_request - _predicate member is set to an NSComparisonPredicate object. All is well in the world. By the time - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section gets called, the _predicate is now a Zombie, which will eventually crash the application when the table attempts to update itself. I'm more or less flummoxed. I'm not releasing the fetched results controller or any of it's parts, and the only part getting dealloc'd is the predicate. Any ideas?

  • Consecutive calls/evaulations in a form?

    - by Dave
    Hey guys, simple question... Working with XLISP to write a program, but I've seemed to run into a simple fundamental problem that I can't seem to work around: perhaps someone has a quick fix. I'm trying to write an if statement who's then-clause evaluates multiple forms and returns the value of the last. In example: (setq POSITION 'DINING-ROOM) (defun LOOK (DIRECTION ROOM) ... ) (defun SETPOS (ROOM) ... ) (defun WHERE () ... ) (defun MOVE (DIRECTION) (if (not(equal nil (LOOK DIRECTION POSITION))) ; If there is a room in that direction ( ; Then-block: Go to that room. Return where you are. (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) ( ; Else-block: Return error (list 'CANT 'GO 'THERE) ) ) The logical equivalent intended is: function Move (Direction) { if(Look(Direction, Room) != null) { SetPos(Look(Direction,Room)); return Where(); } else { return "Can't go there"; } } (Apologies for the poor web-formatting.) The problem I have is with: ( (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) I simply want to return the evaluation of WHERE, but I need to execute the SETPOS function first. XLISP doesn't like the extra parentheses: if I remove the outer set, my WHERE list becomes my else (I don't want that). If I remove the sets around SETPOS and WHERE, it treats WHERE like an argument for SETPOS; I also don't want that. So, how do I simply evaluate the first, then the second and then return the values of the last evaluated?

  • Can't get findnext property of range class error

    - by Lawrence Knowlton
    I am trying to parse a report in Excel 2007. It is basically a report of accounting charge exceptions. The report has sections with a header for each type of exception. There are types of exceptions that are deleted from the report. I'm using a Do While loop to find each header and if the section needs to be deleted I have it do so. If nothing needs to be deleted the code works fine, but right after a section is deleted I get an "Unable to get the FindNext property of the Range Class" error. Here is my code: Sub merge_All_Section_Headers() ' Description: ' The next portion macro will find and format the Tranaction Source rows in the file ' by checking each row in column A for the following text: TRANSA. If a cell ' has this text in it, it is selected and a function called merge_text_cells ' is run, which performs concatenation of each Transaction Source header row and ' deletes the text from the rest of the cells with broken up text. ' lastRow = ActiveSheet.UsedRange.Rows.Count + 1 Range(lastRow & ":" & lastRow).Delete ActiveSheet.PageSetup.Orientation = xlLandscape With ActiveSheet.Range("A:A") Dim searchString As String searchString = "TRANSA" 'The following sets stringFound to either true or false based on whether or not 'the searchString (TRANSA) is found or not): Set stringFound = .Find(searchString, LookIn:=xlValues, lookat:=xlPart) If Not stringFound Is Nothing Then firstLocation = stringFound.Address Do stringFound.Select lastFound = stringFound.Address merge_Text_Cells If ((InStr(ActiveCell.Text, "CHARGE FILER") = 0) And _ (InStr(ActiveCell.Text, "CREDIT FILER") = 0) And _ (InStr(ActiveCell.Text, "PA MIDNIGHT FINAL") = 0) And _ (InStr(ActiveCell.Text, "BAD DEBT TURNOVER") = 0)) Then section_Del 'Function that deletes unwanted sections End If Range(lastFound).Select Set stringFound = .FindNext(stringFound) Loop While Not stringFound Is Nothing And stringFound.Address <> firstLocation End If End With Like I said it works fine when the section_Del is commented out. Any ideas as to how to remedy this would be greatly appreciated. Thanks!

  • custom sorting or ordering a table without resorting the whole shebang

    - by fuugus
    for ten years we've been using the same custom sorting on our tables, i'm wondering if there is another solution which involves fewer updates, especially since today we'd like to have a replication/publication date and would'nt like to have our replication replicate unnecessary entries. i had a look into nested sets, but it does'nt seem to do the job for us. base table: id | a_sort ---+------- 1 10 2 20 3 30 after inserting insert into table (a_sort) values(15) an entry at the second position. id | a_sort ---+------- 1 10 2 20 3 30 4 15 ordering the table with select * from table order by a_sort and resorting all the a_sort entries, updating at least id=(2,3,4) will of course produce the desired output id | a_sort ---+------- 1 10 4 20 2 30 3 40 the column names, the column count, datatypes, a possible join, possible triggers or the way the resorting is done is/are irrelevant to the problem. also we've found some pretty neat ways to do this task fast. only; how the heck can we reduce the updates in the db to 1 or 2 max. seems like an awfully common problem. the captain obvious in me thougth once "use an a_sort float(53), insert using a fixed value of ordervaluefirstentry+abs(ordervaluefirstentry-ordervaluenextentry)/2".. but this would only allow around 1040 "in between" entries - so never resorting seems a bit problematic ;)

  • Salesforce/PHP - outbound messages (SOAP) - memory limit issue? DOMDocument::loadXML() issue?

    - by Phill Pafford
    I'm using Salesforce to send outbound messages (via SOAP) to another server. The server can process about 8 messages at a time, but will not send back the ACK file if the SOAP request contains more than 8 messages. SF can send up to 100 outbound messages in 1 SOAP request and I think this is causing a memory issue with PHP. If I process the outbound messages 1 by 1 they all go through fine, I can even do 8 at a time with no issues. But larger sets are not working. ERROR in SF: org.xml.sax.SAXParseException: Premature end of file Looking in the HTTP error logs I see that the incoming SOAP message looks to be getting cut of which throws a PHP warning stating: DOMDocument::loadXML() ... Premature end of data in tag ... PHP Fatal error: Call to a member function getAttribute() on a non-object This leads me to believe that PHP is having a memory issue and can not parse the incoming message due to it's size. I was thinking I could just set: ini_set('memory_limit', '64M'); // This has done nothing to fix the problem But would this be the correct approach? Is there a way I could set this to increase with the incoming SOAP request dynamically? UPDATE: Adding some code $data = fopen('php://input','rb'); $headers = getallheaders(); $content_length = $headers['Content-Length']; $buffer_length = 1000; $fread_length = $content_length + $buffer_length; $content = fread($data,$fread_length); /** * Parse values from soap string into DOM XML */ $dom = new DOMDocument(); $dom->loadXML($content); ....

  • PHP session_write_close() keeps sending a set-cookie header

    - by Chiraag Mundhe
    In my framework, I make a number of calls to session_write_close(). Let's assume that a session has been initiated with a user agent. The following code... foreach($i = 0; $i < 3; $i++) { session_start(); session_write_close(); } ...will send the following request header to the browser: Set-Cookie PHPSESSID=bv4d0n31vj2otb8mjtr59ln322; path=/ PHPSESSID=bv4d0n31vj2otb8mjtr59ln322; path=/ There should be no Set-Cookie header because, as I stipulated, the session cookie has already been created on the user's end. But every call to session_write_close() after the first one in the script above will result in PHP instructing the browser to set the current session again. This is not breaking my app or anything, but it is annoying. Does anyone have any insight into preventing PHP from re-setting the cookie with each subsequent call to session_write_close? EDIT The problem seems to be that with every subsequent call to session_start(), PHP re-sets the session cookie to its own SID and sends a Set-Cookie response header. But why??

  • How to construct objects based on XML code?

    - by the_drow
    I have XML files that are representation of a portion of HTML code. Those XML files also have widget declarations. Example XML file: <message id="msg"> <p> <Widget name="foo" type="SomeComplexWidget" attribute="value"> inner text here, sets another attribute or inserts another widget to the tree if needed... </Widget> </p> </message> I have a main Widget class that all of my widgets inherit from. The question is how would I create it? Here are my options: Create a compile time tool that will parse the XML file and create the necessary code to bind the widgets to the needed objects. Advantages: No extra run-time overhead induced to the system. It's easy to bind setters. Disadvantages: Adds another step to the build chain. Hard to maintain as every widget in the system should be added to the parser. Use of macros to bind the widgets. Complex code Find a method to register all widgets into a factory automatically. Advantages: All of the binding is done completely automatically. Easier to maintain then option 1 as every new widget will only need to call a WidgetFactory method that registers it. Disadvantages: No idea how to bind setters without introducing a maintainability nightmare. Adds memory and run-time overhead. Complex code What do you think is better? Can you guys suggest a better solution?

  • PropertyPlaceholderConfigurer works from Maven command line, but not from Eclipse?

    - by HDave
    I have Eclipse configured to use an external maven instance. Nonetheless I have an integration test that runs fine from the command line, but fails from within Eclipse. The error is a class Spring application context bean error: Cannot convert value of type [java.lang.String] to required type The culprit it a bean that sets property values using a PropertyPlaceholderConfigurer. <!-- property settings for non-JNDI database connections --> <bean id="placeholderConfigUuid" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" /> <property name="location" value="classpath:database.properties" /> <property name="placeholderPrefix" value="$DS{" /> </bean> I know which bean is failing because it appears in the stack trace and because when I replace the $DS{hibernate.dialect} with a static value it works. I have two questions: 1) Since M2Eclipse is using the same Maven setup as the command line, why does one work and the other fail? 2) How to fix this? I really like the ability to run a single jUnit test from within Eclipse on demand.

  • Encapsulate a set of divs with another div in jQuery

    - by lafoaug
    Hi, I am a little stumped with how to do this. I am using jQuery and wish to encapsulate certain sets of divs with a div. For example I have: <div class="group-1">x</div> <div class="group-1">x</div> <div class="group-2">x</div> <div class="group-2">x</div> <div class="group-3">x</div> And wish to end up with: <div id="set-1"> <div class="group-1">x</div> <div class="group-1">x</div> </div> <div id="set-2"> <div class="group-2">x</div> <div class="group-2">x</div> </div> <div id="set-3"> <div class="group-3">x</div> </div> I am able to cycle through each div and add a div around each one but not the way I want above. Any advice appreciate. Thanks.

  • python matrices - list index out of range

    - by user1888493
    I am writing a function, that takes a matrix as input, such as the one below. Then the it returns the matrix' inverse, where all the 1s are changed to 0s and all the 0s changed to 1s, while keeping the diagonal from top left to bottom right 0s. An example input: g1 = [[0, 1, 1, 0], [1, 0, 0, 1], [1, 0, 0, 1], [0, 1, 1, 0]] the function should output this: g1 = [[0, 0, 0, 1], [0, 0, 1, 0], [0, 1, 0, 0], [1, 0, 0, 0]] When I run the program, it raises a list index out of range error. I'm sure this happens, because the loops I have set up are trying to access values that do not exist. But how do I allow an input of unknown row and column size? I only know how to do this with a single list, but a list of lists? Following you see the transforming function, but not the test function that calls it: def inverse_graph(graph): # take in graph # change all zeros to ones and ones to zeros r, c = 0, 0 # row, column equal zero while (graph[r][c] == 0 or graph[r][c] == 1): # while the current row has a value. while (graph[r][c] == 0 or graph[r][c] == 1): # while the current column has a value if (graph[r][c] == 0): graph[r][c] = 1 elif (graph[r][c] == 1): graph[r][c] = 0 c+=1 c=0 r+=1 c=0 r=0 # sets diagonal to zeros while (g1[r][c] == 0 or g1[r][c] == 1): g1[r][c]=0 c+=1 r+=1 return graph

  • choose javascript variable based on element id from jquery

    - by phoffer
    I feel like this is a simple question, but I am still relatively new to javascript and jquery. I am developing a site for a touch interface that uses unordered lists and jquery .click functions to take input data. I have a section to input a m:ss time, with 3 divs, each containing a list of digits for time. I need to get the input for each column and set it as a variable. I originally designed the inputs to change form inputs, because I didn't understand javascript very much. It was easy to change the 3 hidden inputs by using div id's, but I can't figure out how to do it now with javascript variables. Here is my original jquery code... $("div#time>div>ul>li").click(function() { var id = $(this).parents(".time").attr("name"); var number = $(this).html(); $("input#"+id).val(number); }); The last line sets one of 3 hidden inputs equal to whatever was clicked. I need to make it so separate variables take the inputs, then I can manipulate those variables however I want. Here's a short snippet of the html, to have an idea of how jquery grabs it. <div id="time"> <h1>Time</h1> <div name="minute" class="time" id="t_minute"> M : <ul> The full time html is here: link text Thanks everyone! I've been using SO to answer many questions I've had, but I couldn't find something for this, so I figured I would join, since I'm sure I will have more questions along the way.

  • How can I create an instance of a class that I can use is more than one place in c#

  • UITableView overlaps with NavigationBar in Storyboard Setting on first run

    - by Evils
    I know this seems to be a duplicate question which has been around here many many times, but believe me, I tried all iOS7 and earlier fixes which sets the Layout to a different Edge configuration without any change. My Storyboard looks like this: -> Navigation Controller -> Tab Bar Controller -> MyTableViewController -> VCForCellOne With the first run of my application the UITableView overlaps with the source NavigationController as shown here: After clicking on one of my Cells which pushes the corresponding ViewController to the NavigationController and going back again, everything looks fine as shown here: So everything is as it should be after once pushing another ViewController to the NavigationController and then going back. Switching from Portrait to Landscape and back also fixes the layout problem and everything is layed out as it should be. My ViewController within the Storyboard looks like this: I left it the default value, so I don't know what goes wrong here. I hope you understand my problem here. There's no custom class ViewController here, so no additional code which messes up something here. Any help highly appreciated!

  • Batch Inserts And Prepared Query Error

    - by ircmaxell
    Ok, so I need to populate a MS Access database table with results from a MySQL query. That's not hard at all. I've got the program written to where it copies a template .mdb file to a temp name and opens it via odbc. No problem so far. I've noticed that Access does not support batch inserting (VALUES (foo, bar), (second, query), (third query)). So that means I need to execute one query per row (there are potentially hundreds of thousands of rows). Initial performance tests show a rate of around 900 inserts/sec into Access. With our largest data sets, that could mean execution times of minutes (Which isn't the end of the world, but obviously the faster the better). So, I tried testing a prepared statement. But I keep getting an error (Warning: odbc_execute() [function.odbc-execute]: SQL error: [Microsoft][ODBC Microsoft Access Driver]COUNT field incorrect , SQL state 07001 in SQLExecute in D:\....php on line 30). Here's the code I'm using (Line 30 is odbc_execute): $sql = 'INSERT INTO table ([field0], [field1], [field2], [field3], [field4], [field5]) VALUES (?, ?, ?, ?, ?, ?)'; $stmt = odbc_prepare($conn, $sql); for ($i = 200001; $i < 300001; $i++) { $a = array($i, "Field1 $", "Field2 $i", "Field3 $i", "Field4 $i", $i); odbc_execute($stmt, $a); } So my question is two fold. First, is there any idea on why I'm getting that error (I've checked, and the number in the array matches the field list which matches the number of parameter ? markers)? And second, should I even bother with this or just use the straight INSERT statements? Like I said, time isn't critical, but if it's possible, I'd like to get that time as low as possible (Then again, I may be limited by disk throughput, since 900 operations/sec is high already)... Thanks

  • How to update MySQL table with a cumulative count of events with the same date

    - by John
    I have a table which I pull data from. This data has a date and a stock symbol. There can be multiple rows of data with the same date and different stock symbols. I need to update the table so that there is a running total for all rows with the same date. When a new date occurs the cumulative count re-sets to 1 and then resumes. A typical query: mysql> SELECT Sym 'sym' , fdate as 'FilledDate', TsTradeNum 'numT' -> FROM trades_entered_b2 -> WHERE fDate >= '2009-08-03' AND fDate <= '2009-08-07' -> LIMIT 10; +------+------------+------+ | sym | FilledDate | numT | +------+------------+------+ | WAT | 2009-08-03 | 0 | | ALGN | 2009-08-04 | 0 | | POT | 2009-08-05 | 0 | | PTR | 2009-08-06 | 0 | | SCHW | 2009-08-06 | 0 | | FDO | 2009-08-07 | 0 | | NBL | 2009-08-07 | 0 | | RRC | 2009-08-07 | 0 | | WAT | 2009-08-08 | 0 | | COCO | 2009-08-08 | 0 | +------+------------+------+ What I want: +------+------------+------+ | sym | FilledDate | numT | +------+------------+------+ | WAT | 2009-08-03 | 1 | | ALGN | 2009-08-04 | 1 | | POT | 2009-08-05 | 1 | | PTR | 2009-08-06 | 1 | | SCHW | 2009-08-06 | 2 | | FDO | 2009-08-07 | 3 | | NBL | 2009-08-07 | 4 | | RRC | 2009-08-07 | 5 | | WAT | 2009-08-08 | 1 | | COCO | 2009-08-08 | 2 | +------+------------+------+ What I need to do is update the TsTradeNum column with the correct values. I have tried to create a function and various queries all failed. Any ideas? Thanks in advance

  • Is there an alias for 'this' in TypeScript?

    - by Todd
    I've attempted to write a class in TypeScript that has a method defined which acts as an event handler callback to a jQuery event. class Editor { textarea: JQuery; constructor(public id: string) { this.textarea = $(id); this.textarea.focusin(onFocusIn); } onFocusIn(e: JQueryEventObject) { var height = this.textarea.css('height'); // <-- This is not good. } } Within the onFocusIn event handler, TypeScript sees 'this' as being the 'this' of the class. However, jQuery overrides the this reference and sets it to the DOM object associated with the event. One alternative is to define a lambda within the constructor as the event handler, in which case TypeScript creates a sort of closure with a hidden _this alias. class Editor { textarea: JQuery; constructor(public id: string) { this.textarea = $(id); this.textarea.focusin((e) => { var height = this.textarea.css('height'); // <-- This is good. }); } } My question is, is there another way to access the this reference within the method-based event handler using TypeScript, to overcome this jQuery behavior?

  • Framework/service for hosting and managing files

    - by Peteris Caune
    Hi, in a webapp I'm building there is a planned side feature of supporting product illustrations and manuals (so pictures and PDFs), possibly arranged in galleries. As I'd rather not implement from scratch all of the uploading, managing and serving of this content, I'm looking for existing solutions which I could integrate. For example, I'm considering Flickr--users of webapp specify their Flickr username and then use some naming convention to link objects in my webapp with pictures uploaded in their Flickr account. Very little code to write from my side, maybe just some API calls that proxy Flickr APIs, since Flickr would handle picture uploading, organizing them in sets, storing them in cloud and serving them in various sizes etc. One drawback here is that either all of the the pictures are public or I have to deal with interactive Flickr authorization. Also not sure if Flickr would be happy being used in such manner. What other online services or libraries/frameworks I should look at? My webapp is written in Python/Pylons, so Python libraries would be preferred. I'm already using some of Amazon infrastructure, so frontends to Amazon S3 would be cool. For online services, RESTful API would be nice.

  • odd behavior when checking if radio button selected in jQuery

    - by RememberME
    I had the following check in my jQuery which I thought was working fine to see if a radio button was checked. if ($("input[@name='companyType']:checked").attr('id') == "primary") { ... } Here's the radiobuttons: <p> <label>Company Type:</label> <label for="primary"><input onclick="javascript: $('#sec').hide('slow');$('#primary_company').find('option:first').attr('selected','selected');" type="radio" name="companyType" id="primary" checked />Primary</label> <label for="secondary"><input onclick="javascript: $('#sec').show('slow');" type="radio" name="companyType" id="secondary" />Subsidiary</label> </p> Then, it suddenly stopped working (or so I thought). I did some debugging and finally realized that it was returning an id of "approved_status". Elsewhere on my form I have a checkbox called "approved_status". I realized that when I originally tested this, I must have testing it on records where approved_status is false. And, now most of my approved_statuses are true/checked. I changed the code to this: var id = $("input:radio[@name='companyType']:checked").attr('id'); alert(id); if (id == "primary") { And it's now properly returning "primary" or "secondary" as the id. So, it is working, but it seems that it's not checking the name at all and now just checking radio buttons. I just want to know for future use, what's wrong with the original code b/c I can see possibly having 2 different radio sets on a page and then my new fix probably wouldn't work. Thanks!

  • Call 32-bit or 64-bit program from bootloader

    - by user1002358
    There seems to be quite a lot of identical information on the Internet about writing the following 3 bootloaders: Infinite loop jmp $ Print a single character Print "Hello World". This is fantastic, and I've gone through these 3 variations with very little trouble. I'd like to write some 32- or 64-bit code in C and compile it, and call that code from the bootloader... basically a bootloader that, for example, sets the computer up to run some simple numerical simulation. I'll start by listing primes, for example, and then maybe some input/output from the user to maybe compute a Fourier transform. I don't know. I haven't found any information on how to do this, but I can already foresee some problems before I even begin. First of all, compiling a C program compiles it into one of several different files, depending on the target. For Windows, it's a PE file. For Linux, it's a .out file. These files are both quite different. In my instance, the target isn't Windows or Linux, it's just whatever I have written in the bootloader. Secondly, where would the actual code reside? The bootloader is exactly 512 bytes, but the program I write in C will certainly compile to something much larger. It will need to sit on my (virtual) hard disk, probably in some sort of file system (which I haven't even defined!) and I will need to load the information from this file into memory before I can even think about executing it. But from my understanding, all this is many, many orders of magnitude more complex than a 12-line "Hello World" bootloader. So my question is: How do I call a large 32- or 64-bit program (written in C/C++) from my 16-bit bootloader.

  • javascript prototype problem

    - by Chris Tosswill
    So I have a rather basic javascript problem which I have been slamming my head into a wall over for awhile: <div class='alist'> <ul> <li class='group_1'> An Item </li> <li class='group_1'> An Item </li> <li class='group_2'> An Item </li> </ul> </div> <div class='alist'> <ul> <li class='group_1'> An Item </li> <li class='group_1'> An Item </li> <li class='group_2'> An Item </li> </ul> </div> <script> function toggle_item( num ){ $$( 'li.group_' + num ).invoke('toggle'); } </script> Basically, I need to create a sweeper that sets the div to display:none if all the li are display:none. I think it would start like: function sweep(){ $$('div.alist').each( function( s ) { ar = s.down().children }); } Any suggestions for good tutorials would be welcome as well
