  • Answered: Selecting even table rows from a table element

    - by mvrak
    The issue I am having is: How do I go from a variable pointing at an element to using CSS selectors? I want to make this work: function highlight(table) {$(table " > :even").toggleClass('highlight');} where table is a reference to a table element. I don't want answers that tell me to use $('#table') because that defeats the point of the generality I am trying to make. Thanks

    - by senthil
    Hi all, I came cross a question in my interview. Question: Array of integers will be given as the input and you should find out the middle element when sorted , but without sorting. For Example. Input: 1,3,5,4,2 Output: 3 When you sort the given input array, it will be 1,2,3,4,5 where middle element is 3. You should find this in one pass without sorting. Any solutions for this?

  • Handling a colon in an element ID in a CSS selector

    - by sblundy
    JSF is setting the ID of an input field to search_form:expression. I need to specify some styling on that element, but that colon looks like the beginning of a pseudo-element to the browser so it gets marked invalid and ignored. Is there anyway to escape the colon or something? input#search_form:expression { ///... }

  • Chrome will not load a web page with an <embed> element

    - by rossmcm
    I have been trying to get a simple sound web page going: Sound.html <script> function PlaySound () { var sounder = document.getElementById ("ToneA") ; sounder.Play () ; } </script> <embed id="ToneA" height="1" width="1" src="https://dl.dropboxusercontent.com/u/311035/ToneA.mp3" autostart="false" enablejavascript="true"//> <button onclick="PlaySound () ;">Play</button> The test web page is here. It plays in IE, but not in Firefox or Chrome. My problem: Chrome reports "Could not load VLC Plugin". It seems to be a known problem that the VLC community don't necessarily feel like fixing at the moment, and is a result of Google choosing not to allow some certain kind of plugin. If I disable the plugin I no longer get the message but nothing happens when I click the button. Looking at the console in a debug window I see Uncaught TypeError: undefined is not a function Sound.html:7 PlaySound Sound.html:7 onclick which suggests Chrome could not find anything else to handle the sound file. How to I tell Chrome to use (e.g.) Windows Media Player? * UPDATE * This is apparently because the VLC plugin is a NPAPI plugin and Chrome no longer supports these. I have uninstalled VLC and this has removed the error on loading the webpage with an embedded sound element, but it still doesn't invoke WMP instead.

  • Fade HTML element with raw javascript

    - by jnkrois
    It's my second question of the day related to the same problem, so I apologize for that. I was able to put together a function to "fade out" an element, and it works just fine, my problem is that when I try to reverse it, so the element "fades in" it does not work. I've tried to change the obvious, but I can't understand what I'm doing wrong. My code so far is as follows: Given I have a "div" like so: <div id="test" style="width:200px; height:200px; display:block; opacity:1; background-color:red;"></div> The JavaScript function that I'm using to fade it out is: var getElement = document.getElementById('test'); function fadeOut(elem, speed){ if(!elem.style.opacity){ elem.style.opacity = 1; } var desvanecer = setInterval(function(){ elem.style.opacity -= .02; if(elem.style.opacity < 0){ clearInterval(desvanecer); } }, speed / 50); } fadeOut(getElement, 500); Could somebody take a look at this and let me know what I'm doing wrong, all I want to do is "FADE IN" an element to an opacity equal to "1". By the way, I can't use jQuery, however I'm eager to learn this way. Thanks

  • Redirection on the last Slideshow-Element with Jquery

    - by Agssl
    Hi, I'm very new to Jquery and want to realize a manual slideshow with a page-redirect on the last "next"-button. I detect the last Slide-Element with CSS-Classes and then I want to add a Class to the next button to declare that it is the last next-button of the whole Slideshow. The half of my Code works :) – If I navigate to the last Slide-Element, Jquery adds the Class "last" to the button and if I click on the button with this Class, I'm redirected to the next page – that's what I want. But if I navigate to the last Slide-Element, then click a few times the "prev"-button and then again the next button, I'm instantly redirected although the Class "last" was removed. Thanks in advance and sorry for my bad english. Here's my Code: $(document).ready(function(){ $("#image_nav a:first").attr('id', 'firstSlide'); $("#image_nav a:last").attr('id', 'lastSlide'); $(".dritte_ebene li:first").attr('id', 'firstNavi'); $(".dritte_ebene li:last").attr('id', 'lastNavi'); //Redirect to the next page $("a").click(function(){ if ($("#lastSlide").hasClass("activeSlide")) { $("#weiter").addClass("last"); $('.slide').cycle('pause'); $(".last").click(function(){ window.location.replace("[+PJN_next+]"); }); } }); //Remove "last" if prev is clicked $('#zurueck').click(function(){ $("#weiter").removeClass("last"); }); });

  • Handling element collisions on importing/including XML schemas

    - by eggyal
    Given schema definitions that define the same element differently, can one import/include both definitions and reference them independently from within a third schema definition? For example, given: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <element name="message" type="boolean"/> </schema> and: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <element name="message" type="date"/> </schema> Can one construct the following: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <complexType name="booleanMessageType"> <xs:sequence> <!-- reference to first definition here --> </xs:sequence> </complexType> <complexType name="dateMessageType"> <xs:sequence> <!-- reference to second definition here --> </xs:sequence> </complexType> </schema>

  • Haskell Linear Algebra Matrix Library for Arbitrary Element Types

    - by Johannes Weiß
    I'm looking for a Haskell linear algebra library that has the following features: Matrix multiplication Matrix addition Matrix transposition Rank calculation Matrix inversion is a plus and has the following properties: arbitrary element (scalar) types (in particular element types that are not Storable instances). My elements are an instance of Num, additionally the multiplicative inverse can be calculated. The elements mathematically form a finite field (??2256). That should be enough to implement the features mentioned above. arbitrary matrix sizes (I'll probably need something like 100x100, but the matrix sizes will depend on the user's input so it should not be limited by anything else but the memory or the computational power available) as fast as possible, but I'm aware that a library for arbitrary elements will probably not perform like a C/Fortran library that does the work (interfaced via FFI) because of the indirection of arbitrary (non Int, Double or similar) types. At least one pointer gets dereferenced when an element is touched (written in Haskell, this is not a real requirement for me, but since my elements are no Storable instances the library has to be written in Haskell) I already tried very hard and evaluated everything that looked promising (most of the libraries on Hackage directly state that they wont work for me). In particular I wrote test code using: hmatrix, assumes Storable elements Vec, but the documentation states: Low Dimension : Although the dimensionality is limited only by what GHC will handle, the library is meant for 2,3 and 4 dimensions. For general linear algebra, check out the excellent hmatrix library and blas bindings I looked into the code and the documentation of many more libraries but nothing seems to suit my needs :-(. Update Since there seems to be nothing, I started a project on GitHub which aims to develop such a library. The current state is very minimalistic, not optimized for speed at all and only the most basic functions have tests and therefore should work. But should you be interested in using or helping out developing it: Contact me (you'll find my mail address on my web site) or send pull requests.

  • C# Taking a element off each time (stack)

    - by Sef
    Greetings, Have a question considering a program that stimulates a stack.(not using any build in stack features or any such) stack2= 1 2 3 4 5 //single dimension array of 5 elements By calling up a method "pop" the stack should look like the following: Basically taking a element off each time the stack is being "called" up again. stack2= 1 2 3 4 0 stack2= 1 2 3 0 0 stack2= 1 2 0 0 0 stack2= 1 0 0 0 0 stack2= 0 0 0 0 0 - for (int i = 1; i <= 6; i++) { number= TryPop(s2); //use number ShowStack(s2, "s2"); } Basically I already have code that fills my array with values (trough a push method). The pop method should basically take the last value and place it on 0. Then calls up the next stack and place the following on 0 (like shown above in stack2). The current pop method that keeps track of the top index (0 elements = 0 top, 1 element = 1 top etc..). Already includes a underflow warning if this goes on 0 or below (which is correct). public int Pop() { if(top <= 0) { throw new Exception("Stack underflow..."); } else { for (int j = tabel.Length - 1; j >= 0; j--) { //...Really not sure what to do here. } } return number; }/*Pop*/ Since in the other class I already have a loop (for loop shown above) that simulates 6 times the s2 stack. (first stack: 1 2 3 4 0, second stack 1 2 3 0 0 and so on.) How exactly do I take a element off each time? Either I have the entire display on 0 or the 0 in the wrong places / out of index errors. Thanks in advance!

  • Javascript BBCode Parser recognizes only first list element

    - by nolandark
    I have a really simple Javascript BBCode Parser for client-side live preview (don't want to use Ajax for that). The problem ist, this parser only recognizes the first list element: function bbcode_parser(str) { search = new Array( /\[b\](.*?)\[\/b\]/, /\[i\](.*?)\[\/i\]/, /\[img\](.*?)\[\/img\]/, /\[url\="?(.*?)"?\](.*?)\[\/url\]/, /\[quote](.*?)\[\/quote\]/, /\[list\=(.*?)\](.*?)\[\/list\]/i, /\[list\]([\s\S]*?)\[\/list\]/i, /\[\*\]\s?(.*?)\n/); replace = new Array( "<strong>$1</strong>", "<em>$1</em>", "<img src=\"$1\" alt=\"An image\">", "<a href=\"$1\">$2</a>", "<blockquote>$1</blockquote>", "<ol>$2</ol>", "<ul>$1</ul>", "<li>$1</li>"); for (i = 0; i < search.length; i++) { str = str.replace(search[i], replace[i]); } return str;} [list] [*] adfasdfdf [*] asdfadsf [*] asdfadss [/list] only the first element is converted to a HTML List element, the rest stays as BBCode: adfasdfdf [*] asdfadsf [*] asdfadss I tried playing around with "\s", "\S" and "\n" but I'm mostly used to PHP Regex and totally new to Javascript Regex. Any suggestions?

  • How to change font color inside nav element?

    - by user2924752
    I have a element and I want to change the color of the links within it, but all other links on my page are styled using the following CSS: a:link { color:#22b14c; text-decoration:none; } and here is the nav: <nav id="Nav"> <a href="index.html">Home</a> | <a href="Gallery.html">Library</a> | <a href="Contact.html">Contact</a> | <a href="About.html">About</a> </nav> and the nav css: #Nav { margin-top: 20px; background-color: #000000; color: #f2f2f2; font-size: 40px; font-family: "Calibri"; text-align: center; } I tried a span inside the nav element but that didn't work. How can I change the color for these links only inside the element?

  • Returning a CSS element

    - by TMP
    Is there a way to return a CSS element? I was using Adobe Edge and adding some of my own code in their code tab, but in order to create boundaries I would need to keep track of margin-top or margin-left. The following code works to move the element "woo" but I'm not sure how to call the elements to add something like "|| sym.$("woo").css({"margin-left"0px"}) to the move left code. //Move RIGHT if (e.which == 39) { sym.$("woo").css({"margin-left":"+=10px"}); } //Move UP else if (e.which == 38) { sym.$("woo").css({"margin-top":"-=10px"}); } //Move Left else if (e.which == 37) { sym.$("woo").css({"margin-left":"-=10px"}); } //Move DOWN else if (e.which == 40) { sym.$("woo").css({"margin-top":"+=10px"}); } EDIT: I changed the Left if statement to the following: else if (e.which == 37 && ($("woo").css("margin-left")>0)) { It seems to be working to some extent except for now it won't move left at all! I tried doing <0 too in case I was screwing up a sign but it won't let me move the element left either.

  • Choose a XML node in SQL Server based on max value of a child element

    - by Jay
    I am trying to select from SQL Server 2005 XML datatype some values based on the max data that is located in a child node. I have multiple rows with XML similar to the following stored in a field in SQL Server: <user> <name>Joe</name> <token> <id>ABC123</id> <endDate>2013-06-16 18:48:50.111</endDate> </token> <token> <id>XYX456</id> <endDate>2014-01-01 18:48:50.111</endDate> </token> </user> I want to perform a select from this XML column where it determines the max date within the token element and would return the datarows similar to the result below for each record: Joe XYZ456 2014-01-01 18:48:50.111 I have tried to find a max function for xpath that would all me to select the correct token element but I couldn't find one that would work. I also tried to use the SQL MAX function but I wasn't able to get it working with that method either. If I only have a single token it of course works fine but when I have more than one I get a NULL, most likely because the query doesn't know which date to pull. I was hoping there would be a way to specify a where clause [max(endDate)] on the token element but haven't found a way to do that. Here is an example of the one that works when I only have a single token: SELECT XMLCOL.query('user/name').value('.','NVARCHAR(20)') as name XMLCOL.query('user/token/id').value('.','NVARCHAR(20)') as id XMLCOL.query('user/token/endDate').value(,'xs:datetime(.)','DATETIME') as endDate FROM MYTABLE
