  • Multiple Cookie Generation Issue

    - by Shannon
    Hi all, jQuery newbie here. I need to be able to set multiple cookies within the code without have to change out this variable each and every time. Is there any way to make this code generate unique cookies for different pages? As it is now, I'm having to rename that variable for each page that the jQuery animations exist on. (sbbcookiename) Background on the issue: We are having issues with the sliders not autoplaying once one has already been triggered, due to it the cookie having been cached. Thanks for your help. (function(){ jQuery.noConflict(); var _TIMEOUT= 1000, initTimer= 0, sbLoaded= false, _re= null ; initTimer= setTimeout(initSlider, _TIMEOUT); jQuery(document).ready(initSlider); function initSlider(){ if(sbLoaded) return; if (jQuery('#campaign_name').length > 0) { var sbbcookiename = jQuery('#campaign_name').attr('class'); } else { var sbbcookiename = "slider728x90"; } var slideTimeout //timer ,sbTrigger = jQuery('#slidebartrigger') //convenience ,sbFirstSlide = (document.cookie.indexOf(sbbcookiename) == -1) //check cookie for 'already seen today' ; clearTimeout(initTimer); sbLoaded= true; function toggleSlideboxes(){ if(slideTimeout) clearTimeout(slideTimeout); var isDown = sbTrigger.is('.closeSlide'); jQuery('#slidebar')['slide' + (isDown ? 'Up' : 'Down')]((isDown ? 1000 : 1000), function(){ if(sbFirstSlide){ //if 'first time today' then clear for click-to-replay sbTrigger.removeClass('firstSlide'); sbFirstSlide = false; } sbTrigger[(isDown ? 'remove' : 'add') + 'Class']('closeSlide').one('click', toggleSlideboxes); if(!isDown) slideTimeout = setTimeout(toggleSlideboxes, 4000); }); } if(sbFirstSlide){ //not seen yet today so set a cookie for expire tomorrow, then toggle the slide boxes... var oneDay = new Date(); oneDay.setUTCDate(oneDay.getUTCDate()+1); oneDay.setUTCHours(0, 0, 0, 0); //set to literally day-by-day, rather than 24 hours document.cookie=sbbcookiename+"=true;path=/;expires="+oneDay.toUTCString(); toggleSlideboxes(); }else{ //already seen today so show the trigger and set a click event on it... sbTrigger.removeClass('firstSlide').one('click', toggleSlideboxes); } } })();

  • Custom drop down

    - by Rob
    I'm trying to create a custom drop down and using the code below it works pretty well - only one problem is if i have more than one drop down, all the links will only activate the first drop down. Any ideas on how I would fix that?

  • Repacked proprietary software keeps updating the same deb

    - by Johannes
    I repacked a proprietary program delivered as tar file to a deb file for having a company wide repository. I used reprepro to set up a repository and signed it. A unix timestamp is faking a versioning numbering, so I can have different (real) versions installed at the same time. Almost everything works as expected. The deb file looks like this: mysoft8.0v6_1366455181_amd64.deb Only problem on a client machine it tries to install the same deb file over and over again because it thinks its an update. What do I miss: control file in deb package looks like this: Package: mysoft8.0v6 Version: 1366455181 Section: base Priority: optional Architecture: amd64 Installed-Size: 1272572 Depends: Maintainer: me Description: mysoft 8.0v6 dpkg repackaging and the config in the repository: /mirror/mycompany.inc/conf/distributions: Origin: apt.mycompany.inc Label: apt repository Codename: precise Architectures: amd64 i386 Components: main Description: Mycompany debian/ubuntu package repo SignWith: yes Pull: precise Help much appreciated Added guide: This Is the guide I used to create the repository.

  • Java web UI framework like ASP.NET MVC?

    - by Ethel Evans
    I'm doing some web apps for personal projects that might be shared out with my friends. I'm trying to use skills that will help me at work, but don't have $$ to spend on Visual Studio right now and don't want to try to cobble something together with Express Editions. Since I've been sort of wanting to bring my Java skills up to date and the main skills I want to work on are design and architecture skills, this isn't a big deal - except that I have no idea how to track down the right UI framework. I know I want something based on MVC, to get more practice with frameworks for that design pattern (we're using ASP .NET MVC2 at work). The UIs that I'll be making will be pretty simple - data entry, buttons, text, images. They will need AJAX. Any thoughts about which frameworks to look at? I'll be watching the comments, if anyone wants additional clarification on what I'm looking for.

  • selectors-api for data attributes

    - by MJ
    In HTML5, CSS selectors seem to operate well with data-* attributes. For example: <style> div[data-foo='bar'] { background:#eee; } </style> <div data-foo='bar'>colored</div> <div>not colored</div> will properly style the first . But, attempts to select such elements using the selectors-api fail. Examples: var foos = document.querySelectorAll("div[data-foo]='bar'"); or var foos = document.querySelectorAll("div data-foo='bar'"); in Chrome and Safari, this produces a cryptic error: SYNTAX_ERR: DOM Exception 12 Any thoughts on how to use the selectors-api to properly select elements on the basis of data-* attributes?

  • Software design methods for Java or any other programming language

    - by IkerB
    I'm junior programmer and I would like to know how professionals write their code or which steps they follow when they are creating new software. I mean, which steps they follow, which programming methodology, software architecture design application software, etc. I would like to find a tutorial where they explain from the beginning which steps I have to follow from The Idea I have in my mind to the final version of the application in any language. Or perhaps how is your programming steps or rules that you used to follow. Because everytime I want to create the an application I spend few time on the design and a lot of time coding (I know, that's not good).

  • Direct X-forwarding

    - by Sean Houlihane
    I'm struggling to set up X-forwarding between 2 different machines on my local network and my ubuntu desktop. I'm able to connect using ssh x-forwarding one one machine, but the other machine (a Qnap TS-219P II) seems to have a less functional build of SSH on it, and I'd rather use a simpler approach. I've set $DISPLAY, and done 'xauth list $DISPLAY' on the desktop, then 'xauth add ' on the remote machine. From the remote machine, I just get xterm xterm Xt error: Can't open display: 192.168.0.4:0.0 Now, oddly, if I connect via ssh -X, there is a different magic cookie for the tunnelled port (but neither seems to work). I'm wondering if there is a port which needs to be enabled to permit X connections from the LAN? If so, how? The proper solution might be to re-build all the packages which are preventing X-forwarding from working on my QNAP machine, but lets assume for the purposes of this question that I've tried building enough packages on that architecture already and want to run X without the overhead of encryption.

  • Cinema4D XML scene not rendering texture

    - by George Profenza
    I was playing with the Cinema 4D command line options and ran into a problem that might not be specific to the command line options. I saved a basic scene(a textured cube) in two formats: the original .c4d(binary) format and .xml(Cinema 4D XML via File Export). the .c4d file renders with the texture applied, while the .xml file renders without the texture applied. I had a look at the xml file, and there is a node that holds a reference to the image used as texture, and there is another node which seems to store the pixels in xml. When I opened the .xml document in Cinema 4D, the document did store the material with the texture, but it was not applied to the object. Am I missing something when I export to XML ? How can I export a Cinema 4D XML that can render with the texture applied ?

  • How do I get HTML Markup for createRange() in Firefox

    - by OneNerd
    I am currently using code similar to this: try { // IE ONLY var theElement = "myElementName"; window.frames[theElement].focus(); var selection = window.frames[theElement].document.selection.createRange(); alert ( selection.htmlText ); } catch(e) { var selection = window.frames[theElement].document.getSelection(); alert ( selection ); } As you can see, I am accessing a node from an iframe (no fun already). I am definitely in new territory here, so am sure there are more issues to arise, but right now, I am trying to get Firefox to give me the same result as IE. In IE, I can access the HTML code of the selection by using the (apparently IE-only) htmlText property of the object returned by createRange(). What I am looking for is the Firefox equivalent to that (or a function that I can use to give me the same result). Anyone know how to do this?

  • Find the xmlHttpRequest resource in aspx page

    - by DJStroky
    I'm trying to find an xmlHttpRequest or similar resource that I can query directly to obtain an xml file for my own purposes. At this site it is possible to browse a Google Map mashup with markers. Unfortunately it is only possible to view all markers at a small view range, whereas I simply want to obtain all the information at once for the entire state. Using the firebug console in firefox I can enter the following javascript line to obtain the xml that I desire: document.getElementById("stationXML").value I tracked this document element down to an <input> tag, but I can't figure out how that input is set. Thanks in advance for your help!

  • How important is using the same language for client and server?

    - by Makita
    I have been evaluating architecture solutions for a mobile project that will have a web-service/app in addition to native apps and have been looking at various libraries, frameworks, and stacks like Meteor, this being a sort of "open stack package framework", is tightly bound with Node.js. There is a lot of talk about the benefits of using the same language both client and server side, and I'm not getting it. I could understand if you want to mirror the entire state of a web application on both client and server but struggling to find other wins... Workflow efficiency? I'm trying to understand why client/server language parity is considered to be a holy grail. Why does client/server language parity matter in software development?

The given example works for PdfReader but not for PdfCopy. Edit: Why do I need PdfCopy? I tried copying a word pdf export. Some word hyperlinks will not work when you try to copy pages with PdfReader. Only PdfCopy transfers all needed page informations. Edit: (SOLVED) You need to use reader.GetPageRotation(i);

In another words I want to allow page break from odd to even page but I want to prohibit breaks from even to odd page. I tried to write macro: \newcommand{\nl}{ \\ \ifodd\c@page \relax \else \nopagebreak \fi} and use it instead of \ (I don't use any other line breaks commands in my document) but it does not work.

  • Is it really wrong to version documents using CouchDB's default behaviour?

    - by Tomas Sedovic
    This is one of those "I know I shouldn't do this but it's oh so convenient." questions. Sorry about that. I plan to use CouchDB for storing a bunch of documents and keeping their entire revision history. CouchDB does the versioning automatically, but it is strongly discouraged for programmer's use: "You cannot rely on document revisions for any other purpose than concurrency control." From what I've found on the CouchDB wiki, the versions can get deleted either during compaction or during replication. As far as I can tell, Compaction must always be triggered manually and Replication occurs only when there's more than one database server. The question is: if I won't run compaction and will use only single database instance for my documents, can I just use CouchDB's document versioning and expect it to work? What other problems I might run into? E.g. does not running compaction hurt the performance or consume significantly more disk space (than if I did handle the versioning manually)?
