  • DOM Elements with same id and jQuery

    - by Steve
    Hi I have multiple elements with the same structure in my application. Second div element's id varies as per the comment id in the db which is unique. There are elements with the id 'vote_up' and 'vote_down'. This gets repeated for each comment.What happens is that, as I mentioned, there are multiple comments. I want to perform an Ajax request. First of this structure functions properly using ajax, but the rest does an http request. Btw I am developing a rails application and I am using jQuery. <div id="post_comment"> john<i> says </i> Comment<br/> <div id="comment_10_div"> **<form action="/comments/vote_up" id="vote_up" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[post_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote up" /> </form> <label id="comment_10">10</label> **<form action="/comments/vote_down" id="vote_down" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[place_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote Down" /> </form> </div> Can you please help me to solve this Thanks

  • NHibernate - Saving simple parent-child relationship generates unnecessary selects with assigned id

    - by Alice

  • Which Xorg driver (not kernel driver) to use with GMA500/Poulsbo video hardware in 12.04

    - by Somejan
    I have a Asus EeePC with a GMA500 video card. I followed the instructions on https://wiki.ubuntu.com/HardwareSupportComponentsVideoCardsPoulsbo/, which made the netbook boot correctly. Without any xorg.conf file, Xorg uses the VESA driver, which is quite slow. Manually specifying fbdev as driver in xorg.conf also works. Which one should I use? Are there any other drivers for Xorg that do better at 2d accelleration (since the kernel driver doesn't support 3d acceleration)?

  • Installing Ubuntu on a computer with USB 3.0 hardware

    - by Matt
    I'm installing Ubuntu 10.10 32-bit version on an HP Envy 15. I get the same problem these people have here: "unable to find a medium containing a live file system" error when installing but the question was never resolved. I spent so long researching and got so frustrated that I took my computer down to a shop and asked them to install it for me. It took them a while but they managed to get it installed. The reason for this error they had said was because Ubuntu didn't have the USB 3.0 drivers it needed to install properly. I'm reinstalling Ubuntu yet again and I've run into the same issue so my question is: does anyone know.. a) Where to get these USB 3.0 drivers? b) How to get them installed when installing the Ubuntu OS? Thanks, Matt

  • Circular motion on low powered hardware

    - by Akroy
    I was thinking about platforms and enemies moving in circles in old 2D games, and I was wondering how that was done. I understand parametric equations, and it's trivial to use sin and cos to do it, but could an NES or SNES make real time trig calls? I admit heavy ignorance, but I thought those were expensive operations. Is there some clever way to calculate that motion more cheaply? I've been working on deriving an algorithm from trig sum identities that would only use precalculated trig, but that seems convoluted.

  • Is it legal to ask photo ID and credit card copy in the U.S

    - by selim
    I regularly order from online shops around the world and I have not see any case where the company asks for photo ID or credit card copy. Yesterday I make an order from linode.com and my order is on hold because of their "fraud check system". Is it common to ask those info in U.S. where I have never asked such info in here (Istanbul, Turkey). And I already asked what is their motive and legal stand and the reason my order is hold by their fraud system. And I also added whether is because I live in Istanbul, Turkey. Their answer was as following: "We would not be able to disclose specific information related to our fraud system." And I'm asked repeatedly whether I want to cancel my order or not. I dont questioning reputation of linode.com if I think so, I did not make an order. I think asking for photo ID is neither legal nor provide any security.

  • Phonon - Audio Hardware Setup

    - by Michael
    Does anyone know what configuration file is modified when I change settings within this area of the system settings? I keep choosing my Logitech USB Headset as the soundard, and, when I hit apply, it accepts that change and all is good. However, as soon as I close the system settings window, it loses the setting, so I have to leave it open all the time. How can I make this setting permanent? Thanks for any assistance. I'm actually running Kubuntu 11.10.

  • Graphics hardware warning when updating to 14.04

    - by pacomet
    As I use Ubuntu at work I just update only LTS versions but now I'm not sure if I can/should. As my computer is now ten years old I would change if was mine but as it is owned by my employer I have to work with it. It's not a bad one, it runs fine (this was not true when still had Windows on it ;-). When updating to 14.04, it warns about possible bad/slow performance with Unity 3D so I stop updating as I am at work, not my own computer. As I understand from http://askubuntu.com/a/438958/25305 Nvidia Geforce FX 5500 graphics card is still supported in 14.04. Now, in 12.04, I have driver version 173 and unity 2d runs fine for me. output of /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.39 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no Should I update? Is it better to stay with 12.04? Thanks

  • Edit exim4 Message-ID for releasing blocked mail by Mailscanner

    - by F12
    Our sysadmin team edits the field Message-ID in exim4 header files (ending with -H) and substitues the first char after "<". e.g: 077I Message-ID: <[email protected] -- 077I Message-ID: <[email protected] I'd like to write a script to release the mails. I changed the part between "<" and "@" in the field Message-ID and substituted a hash value so the Message-ID looks like: 077I Message-ID: <[email protected] Now exim says "format error" in the log and the mail is not released. There was no change except for this one field. Why can't the ID be substituted like that? Does it need to be the exact same length? It's exim4 version 4.69-2ubuntu0.3.

  • Change Keybindings (hardware to software)

    - by Daniel
    I ran a search for this, but the answers I saw were referring to something altogether different than what I'm asking for. So let me clarify: I'm not asking how to change key-combo shortcuts. I'm asking--how do you actually change what your computer thinks you did when you press a given key? An example of what I mean (and the reason I'm asking). I'm a Chrome user, and I use Windows alongside Ubuntu. I own a Lenovo Thinkpad T61p--it came with my scholarship package, and I would have shopped for a nice computer if I could have. The T61p has two buttons above the left and right arrow keys that relate to browser commands to go back and forth one page. This is extremely frustrating for me, as I use the arrow keys, and a single accidental keystroke will catch me going back a page, losing temporary data, and yelling at my stupid keyboard. At the same time, I'm the type of person who keeps way too many tabs open. Chrome doesn't let me refigure keyboard shortcuts, and the only way it allows you to switch between tabs are ctrl+tab and ctrl+shift+tab, and ctrl+page up/down. I was using Notepad++, and they had finally found the solution to both problems! The page back and forth keys functioned as tab back and forth keys. I went through quite some effort to learn how to change the keybindings in Windows. The page back and page forward keys are now the page up and page down keys, respectively, and if I hit control, they let me switch tabs easily, and rather pleasantly. And if I hit the keys by accident, no harm, no foul. Alas, I'm in Ubuntu now, and I need to go through the process again. And while I couldn't just find the answer online, like I did for Windows, I know Ubuntu has nice, supportive communities like this one, where, hopefully, somebody can tell me how to do either what I did in Windows, or directly make it so that my computer changes tabs when I hit those buttons (removing the ctrl button from the tab-changing command).

  • Useful programming languages for hardware programming

    - by Sebastian Griotberg
    I am thinking to take the next semester a course called "Digital systems architecture", and I know that we need to program micro-controllers with several programming languages such as C, C++, verilog, and VHDL. I want to be prepared to take that course, but I need to know if I need to study deeper these languages. At this moment, I have taken one course in basic Java dealing with basic methods, data types, loop structures, vectors, matrices, and GUI programing. Must I study deeper Java and then go with C, and C++? Besides, I know basic verilog and VHDL.

  • UEFI hardware and dual booting with windows

    - by user39803
    I've been struggling for 3 days trying to dual boot Ubuntu 11.10 and Windows 7. I want to use an SSD for my Ubuntu installation and an hdd for Windows. I realized that I have to install windows first and then ubuntu, and so I did that. When I first install windows it boots fine from my hdd, but when I add ubuntu on my ssd and restart, I get a black screen with a blinking cursor. I've read many forums where this is asked but haven't found a single solution that works. I've tried boot repair. It told me to make a fat ESP partition and I did that as well but it still doesn't work. I'm a noob and any suggestions would be really appreciated.
