  • trying to make an accordion menu from a list - jquery indexhibit

    - by orionrush
    Hello - Im teaching my self javascript & jquery so this might be a bit of a low brow question or entirely too much code for anyone to wade through, but Im hoping for some feedback. I have looked around and haven't found a thread that looks like it will deals neatly with my question. Im using the cms indexhibit (cant create a new tag!) and trying to create an accordion style menu from the menu list it generates. I basically have the behaviour Im after, modifying an existing bit of work but there are quite a few foibles, which are no doubt a conflict between the .click and .toggle and a confused use if statements. I basically want to start from scratch and redo this so I can a) learn from my mistakes b) understand what's happening. Im having trouble now because I dont know where to go from here, or how to trouble shoot it. Can anyone give me a quick analysis how the the script in the head of the document work together? Also any insight into the nature of the conflicts Im seeing and what approach might take to remedy them? If you were going to start afresh what would be your approach? Here is a test to see it in action (warts and all): http://stillstatic.nfshost.com/ This script goes into the document head: <script type='text/javascript'> //im not entirely clear as to what this achieves path = 'path/to/script/'; $(document).ready(function() { setTimeout('move_up()', 1); expandingMenu(0); expandingMenu(1); expandingMenu(2); expandingMenu(3); expandingMenu(4); //etc }); </script> the generated list: <ul> <li class='section-title active_menu'>blogs</li> <li><a class="active" href='#' onclick="do_click();">3</a></li> </ul> <ul> //this menu section dose not have a label: class .section-title <li><a href='#' onclick="do_click();">1</a></li> <li><a href='#' onclick="do_click();">2</a></li> </ul> <ul> //this menu section is not the 'active menu' this is achieved by the jquery script <li class='section-title'>writing</li> <li><a href='#' onclick="do_click();">4</a></li> <li><a href='#' onclick="do_click();">5</a></li> </ul> The meat of in an external script: function expandingMenu(num) { var speed = 500; var menu_title = $("#menu ul").eq(num).children(":first"); // ie. first child be the title with the class .section-title unless the user turned it off var menu_items = $("#menu ul").eq(num).children().filter(function (index) { return index 0; }); // ie. any li NOT in position 0, below li.section-title if (menu_items.is(".active") == true) { menu_title.addClass("active_menu"); //Add a class to the active list so we can style it. } if (menu_title.is(".section-title") == true){ // this if prevents interference with users who turn off the section titling if ((menu_items.is(".active") == false) && (menu_items.is(":visible")) ) { menu_items.hide(0);// first we hide the inactive exhibits } $('li').click(function (){ if ( (menu_title.is(":visible") == true) ){ menu_items.hide(speed); } if ( (menu_items.is(":hidden") == true ) && (('')) ){// ?! without this second condition things break down. . . menu_items.show(speed); } }) menu_title.css({cursor:"pointer"}).toggle( // add click functions + pointer to menu_title function () { menu_items.show(speed);//Open it up }, function () { // this function could even be empty but without the if things get weird if (menu_items.is(".xx")) menu_items.hide(speed); //Take the menu item off of active duty! } ) } }

  • Size of a sharepoint web application

    - by Indra
    How do you figure out the current size of the sharepoint web application? Better yet, the size of a site collection or a subsite. I am planning to move a site collection from one farm to another. I need to plan the storage capacity first.

  • How should I implement simple caches with concurrency on Redis?

    - by solublefish
    Background I have a 2-tier web service - just my app server and an RDBMS. I want to move to a pool of identical app servers behind a load balancer. I currently cache a bunch of objects in-process. I hope to move them to a shared Redis. I have a dozen or so caches of simple, small-sized business objects. For example, I have a set of Foos. Each Foo has a unique FooId and an OwnerId. One "owner" may own multiple Foos. In a traditional RDBMS this is just a table with an index on the PK FooId and one on OwnerId. I'm caching this in one process simply: Dictionary<int,Foo> _cacheFooById; Dictionary<int,HashSet<int>> _indexFooIdsByOwnerId; Reads come straight from here, and writes go here and to the RDBMS. I usually have this invariant: "For a given group [say by OwnerId], the whole group is in cache or none of it is." So when I cache miss on a Foo, I pull that Foo and all the owner's other Foos from the RDBMS. Updates make sure to keep the index up to date and respect the invariant. When an owner calls GetMyFoos I never have to worry that some are cached and some aren't. What I did already The first/simplest answer seems to be to use plain ol' SET and GET with a composite key and json value: SET( "ServiceCache:Foo:" + theFoo.Id, JsonSerialize(theFoo)); I later decided I liked: HSET( "ServiceCache:Foo", theFoo.FooId, JsonSerialize(theFoo)); That lets me get all the values in one cache as HVALS. It also felt right - I'm literally moving hashtables to Redis, so perhaps my top-level items should be hashes. This works to first order. If my high-level code is like: UpdateCache(myFoo); AddToIndex(myFoo); That translates into: HSET ("ServiceCache:Foo", theFoo.FooId, JsonSerialize(theFoo)); var myFoos = JsonDeserialize( HGET ("ServiceCache:FooIndex", theFoo.OwnerId) ); myFoos.Add(theFoo.OwnerId); HSET ("ServiceCache:FooIndex", theFoo.OwnerId, JsonSerialize(myFoos)); However, this is broken in two ways. Two concurrent operations can read/modify/write at the same time. The latter "wins" the final HSET and the former's index update is lost. Another operation could read the index in between the first and second lines. It would miss a Foo that it should find. So how do I index properly? I think I could use a Redis set instead of a json-encoded value for the index. That would solve part of the problem since the "add-to-index-if-not-already-present" would be atomic. I also read about using MULTI as a "transaction" but it doesn't seem like it does what I want. Am I right that I can't really MULTI; HGET; {update}; HSET; EXEC since it doesn't even do the HGET before I issue the EXEC? I also read about using WATCH and MULTI for optimistic concurrency, then retrying on failure. But WATCH only works on top-level keys. So it's back to SET/GET instead of HSET/HGET. And now I need a new index-like-thing to support getting all the values in a given cache. If I understand it right, I can combine all these things to do the job. Something like: while(!succeeded) { WATCH( "ServiceCache:Foo:" + theFoo.FooId ); WATCH( "ServiceCache:FooIndexByOwner:" + theFoo.OwnerId ); WATCH( "ServiceCache:FooIndexAll" ); MULTI(); SET ("ServiceCache:Foo:" + theFoo.FooId, JsonSerialize(theFoo)); SADD ("ServiceCache:FooIndexByOwner:" + theFoo.OwnerId, theFoo.FooId); SADD ("ServiceCache:FooIndexAll", theFoo.FooId); EXEC(); //TODO somehow set succeeded properly } Finally I'd have to translate this pseudocode into real code depending how my client library uses WATCH/MULTI/EXEC; it looks like they need some sort of context to hook them together. All in all this seems like a lot of complexity for what has to be a very common case; I can't help but think there's a better, smarter, Redis-ish way to do things that I'm just not seeing. How do I lock properly? Even if I had no indexes, there's still a (probably rare) race condition. A: HGET - cache miss B: HGET - cache miss A: SELECT B: SELECT A: HSET C: HGET - cache hit C: UPDATE C: HSET B: HSET ** this is stale data that's clobbering C's update. Note that C could just be a really-fast A. Again I think WATCH, MULTI, retry would work, but... ick. I know in some places people use special Redis keys as locks for other objects. Is that a reasonable approach here? Should those be top-level keys like ServiceCache:FooLocks:{Id} or ServiceCache:Locks:Foo:{Id}? Or make a separate hash for them - ServiceCache:Locks with subkeys Foo:{Id}, or ServiceCache:Locks:Foo with subkeys {Id} ? How would I work around abandoned locks, say if a transaction (or a whole server) crashes while "holding" the lock?

  • Windows 8 install fails

    - by HackToHell
    I have the windows 8 release preview 32 bit iso and it fails to install when booted out of a flash drive, it copies the files and the boot loader installs but the install hangs when I boot into Windows 8 the first time, it simply keeps on spinning forever. I did a vhd install of Windows 8 developer preview and it installed fine. Looking at the partition from Windows 7, I can see that the files are present.

    My wife has a small business that she wants to offer a free WiFi hotspot in. She suggested opening up our private 'net connection to the customers - T&Cs of our internet provider and thoughts of random people viewing kiddy porn floated through my mind. So, first action will be to get a separate internet connection. But I have no experience of setting up a public WiFi connection. What considerations should I make with regards to: WAP Security Access logging?

  • How can I start new window in the same screen session automatically?

    - by Mato
    I read How can I start multiple screen sessions automatically?, but I don't understand the first accepted reply: screen -dmS "$SESSION_NAME" "$COMMAND" "$ARGUMENTS" In my case I need to automatically create one screen session for one script, and afterwards I need to create a new window in the same session for another script. Manually, I would: run screen enter command CTRL+A CTRL+C enter command CTRL+A CTRL+D How can I do this automatically in a script? A simple example would help me a lot. Thank you for replies.

  • How would I recognize the "spoon-feeding problem" on a dynamic webapp server?

    - by Don Spaulding
    The "spoon-feeding problem", as it was recently explained to me, happens when connections to your application server are tied up feeding data across slow network connections to your clients. This makes sense to me and now I understand the importance of putting a highly-concurrent proxy in front of my app servers. My question is, how did the first person to recognize this problem figure it out? What *nix tools and troubleshooting techniques would help me to recognize this problem if I hadn't had it explained to me?

  • Two Raid 1s in a single system?

    - by DebAtCQ
    I'm building a Raid array for the first time in my system and I have a question regarding having multiple Raid 1 arrays in a single Win 7 system. I'm a bit of an organizational freak with my data and I currently have two separate hard drives I want to mirror. The new motherboard I'm looking to buy supports Raid, so my question is this: a) can I have more than one Raid 1 array in a single system? b) would I have to buy a separate controller for the second array?

  • How to recover data from a partially overwritten partition

    - by shredder12
    By mistake, I configured a 900GB partition to be part of a 50GB raid. The sync is complete and my understanding is that only the first 50GB of the bigger partition is overwritten. How do I recover the rest of the data? When I try to mount this partition by identifying it as ext3, it mounts only the 50GB overwritten space. This partition was earlier divided into various logical volumes(all ext3 filesystems) through LVM. Any suggestions?

  • How do I unlink a file-folder relationship?

    - by Ovesh
    When asking IE to save an HTML page locally, with the option "Web page, complete", an html file is created along with a folder that contains all associated files (images, js, css etc). An association is created between the html file and the folder, so that when the file is deleted/moved, so is the folder. First, I'd like to know what this kind of association is called. Further, I'd like to know how to "unlink" this file-folder association.

  • Recovering from backup without original install media

    - by KGendron
    A machine from my old job had a complete hard drive failure. I have backups but I'm running into severe problems restoring from them. The only install media was a secondary restore partition on the system's hard drive. I hate whoever came up with that idea more than i can possibly express with words. I spent several days trying to recover the disk - it is pretty well shot and none of my best tricks could even get it to show up in the bios/ The machine that broke is an hp with xp media center edition on it (I don't know why either). The backups were created using the default windows backup tool - I have .bfk file on an external hardrive that i am trying to restore from. I've replaced the hard drive. My home machine is running windows 7 64bit and i'm trying to use it as a platform to restore to the other disk. I downloaded the window 7 nt-restore utility, however no matter what i do it restores to my C drive rather than the specified drive. Fortunately win7 security settings prevented it from being a complete disaster - but still not a happy thing. I tried firing up the xp virtual machine. I can browse to the backups but it says they are invalid and refuse to let me view/ continue with the restore. I tried installing XP to an extra harddrive on my machine - however it bluescreens on me during the install process and I cry. I tried installing xp pro to the new drive and attempted to restore over it, it of course blackscreened on me as that was a stupid idea. I made two partitions on the new hard drive (Apparently the bios on this accursed piece of junk doesn't allow hd partitions larger than 200G anyways and thus fails 40 minutes into the install with an ever-descriptive "Disk Read Error". Guess how i spent last weekend? My last idea was to install xp pro to the second partition and then use it to restore from backup to the first. After the first restart it gives me the error "Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware". My brain made one of those bad hard drive clicky noises. I've tried several boot disks but they don't seem to work. If anyone has a link to a good one it would be greatly appreciated. Anyone have any more ideas? - I really hate asking on what seems like such a simple issue but i am quite literally at my wit's end. Thanks - and sorry for the really long post.

    When either selecting a data center as a co-location facility or designing a new one from scratch, what would your ideal specification be? Fundamentally, diversified power sources, multiple ISPs, redundant generators, UPS, cooling, and physical security are all desireable. What are the additional key requirements that someone might not consider on the first pass? What are the functional details someone might not consider during the initial high level design?

  • I keep getting a Java incoming connections pop up

    I keep getting the following message, "Do you want the application “java” to accept incoming network connections?" First of all, what application? Second, if it's part of the browser, which sometimes the browser isn't open, it doesn't show me what page is requesting it. "Application" is very generic. Third what does that mean? Is it asking if anyone on the internet can make connections to my computer?

  • Ubuntu server boot degraded raid

    - by beacon_bonanza
    I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails.

  • (Why) are IEC C5/C6 connectors a necessity? Why not use C13/C14?

    - by Mike
    That's a question I was asking myself the first time I saw such a weird C5 plug. That was a while ago, but I came across it again and haven't found an answer yet. The only thing I could find out is that C5 is with 2.5A and C13 with 10A. But I guess it would technically be no problem building an AC adapter (e.g. for laptops) in which you plug the far more common C13 connector. http://en.wikipedia.org/wiki/IEC_connector
