  • remove a:hover using javascript (not using jquery... don't ask)

    - by Cyprus106
    I thought this would be pretty simple.... Basically, it's a 5-star rating system. When a user clicks, for example, three stars... I want to freeze those three stars right where they're at. I've been trying to simply remove the hover for the a href so it stays what it was at... maybe that's not the right method. I've exhausted absolutely everything I can think of... By the way this is straight javascript, not jquery or anything. It's crazy, I know but all of the JS was written straight.... I've got this class: .star-rating li a{ display:block; width:25px; height: 25px; text-decoration: none; text-indent: -9000px; z-index: 20; position: absolute; padding: 0px; } .star-rating li a:hover{ background: url(images/alt_star.png) left bottom; z-index: 2; left: 0px; } .star-rating a:focus, .star-rating a:active{ border:0; -moz-outline-style: none; outline: none; } .star-rating a.one-star{ left: 0px; } .star-rating a.one-star:hover{ width:25px; } and this code: <ul class='star-rating'> <li><a href="#" onclick="javascript: vote(<?=$id;?>, 1); disableStars(); return false;" title='1 star out of 5' id="1s" class='one-star'>1</a></li>

  • Javascript Onclick Problem with Table Rows

    - by Shane Larson
    Hello. I am having problems with my JScript code. I am trying to loop through all of the rows in a table and add an onclick event. I can get the onclick event to add but have a couple of problems. The first problem is that all rows end up getting set up with the wrong parameter for the onclick event. The second problem is that it only works in IE. Here is the code excerpt... shanesObj.addTableEvents = function(){ table = document.getElementById("trackerTable"); for(i=1; i<table.getElementsByTagName("tr").length; i++){ row = table.getElementsByTagName("tr")[i]; orderID = row.getAttributeNode("id").value; alert("before onclick: " + orderID); row.onclick=function(){shanesObj.tableRowEvent(orderID);}; }} shanesObj.tableRowEvent = function(orderID){ alert(orderID);} The table is located at the following location... http://www.blackcanyonsoftware.com/OrderTracker/testAJAX.html The id's of each row in sequence are... 95, 96, 94... For some reason, when shanesObj.tableRowEvent is called, the onclick is set up for all rows with the last value id that went through iteration on the loop (94). I added some alerts to the page to illustrate the problem. Thanks. Shane

  • In Javascript event handling, why "return false" or "event.preventDefault()" and "stopping the event

    - by Jian Lin
    It is said that when we handle a "click event", returning false or calling event.preventDefault() makes a difference, in which the difference is that preventDefault will only prevent the default event action to occur, i.e. a page redirect on a link click, a form submission, etc. and return false will also stop the event flow. Does that mean, if the click event is registered several times for several actions, using $('#clickme').click(function() { … }) returning false will stop the other handlers from running? I am on a Mac now and so can only use Firefox and Chrome but not IE, which has a different event model, and tested it on FF and Chrome and all 3 handlers ran without any stopping…. so what is the real difference, or, is there a situation where "stopping the event flow" is not desirable? this is related to http://stackoverflow.com/questions/3042036/using-jquerys-animate-if-the-clicked-on-element-is-a-href-a and http://stackoverflow.com/questions/2017755/whats-the-difference-between-e-preventdefault-and-return-false

  • Javascript onbeforeunload Issue

    - by Nik
    Alright, I have an issue with the following code. What happens is when a user closes their browser, it should prompt them to either click OK or click CANCEL to leave the page. Clicking OK would trigger a window.location to redirect to another page for user tracking (and yes, to avoid flame wars, there is a secondary system in place to assure accurate tracking, in the event of the user killing the browser from the task manager (as mentioned in similar questions)). CANCEL would remain on the page, the issue being that no matter what button you hit, you get redirected as if you wanted to leave the page. The relevant code is below. window.onbeforeunload = confirmExit; function confirmExit() { var where_to = confirm("Click OK to exit, Click CANCEL to stay."); if (where_to == true) { window.location="logout.php"; } if (where_to == false){ alert("Returning..."); } }

  • Any way to pass parameters programmatically to an onclick function?

    - by RenderIn
    I have an onclick function which performs several tasks. In another javascript function I do not have access to the context variables needed to perform these tasks. To get around this I have been simply calling the onclick function directly. The problem I have now is that I'd like to perform a task after an Ajax action in the onclick completes. Is there any way for me to pass a function to the onclick method of a link? What would the onclick attribute look like? e.g. something like this: <a id="link3" href="javascript:void(0);" onclick="function(callback) { X(a); Y(b); Z(c, callback); };">click me</a> Clicking on this would pass "undefined" as the callback, while I could also call it explicitly like this: document.getElementById("link3").onclick(function() { alert("Completed all tasks"); } ); Is something like this possible? Basically I want to be able to pass an optional parameter to the onclick method, but if it's absent I want it to behave as if there were just procedural code in the onclick.

  • Need Help With This Simple Script (JavaScript Noob Question)

    - by three3
    Hi everyone, I am new to JavaScript (only a couple of days of reading a book) and I am stuck on this code snippet. I have looked at it over and over again but cannot seem to figure out why it is not working. I am sure it is something really simple that I have just looked over but I really just need a fresh pair of eyes to look at this. The code is supposed to update a placeholder image on a page without the page having to reload. But when I am clicking on the link of an image, it is taking me to the link where the image is located instead of replacing the placeholder image. Here is my HTML code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Image Gallery</title> <script type="text/javascript" src="scripts/showPic.js"></script> </head> <body> <h1>Snapshots</h1> <ul> <li> <a href="images/cat.jpg" onclick="showPic(this); return false;" title="A Cat">Cat</a> </li> <li> <a href="images/night.jpg" onclick="showPic(this); return false;" title="Night">Night</a> </li> <li> <a href="images/coke.jpg" onclick="showPic(this); return false;" title="Coke">Coke</a> </li> <li> <a href="images/sport.jpg" onclick="showPic(this); return false;" title="Sports">Sport</a> </li> <li> <a href="images/mnms.png" onclick="showPic(this); return false;" title="MnM's">MnM's</a> </li> <li> <a href="images/kid.jpg" onclick="showPic(this); return false;" title="A Kid">Kid</a> </li> </ul> <br /> <img src="images/placeholder.jpg" title="Place Holder Image"> </body> </html> And here is the JavaScript function I am using to get this done: <script type="text/javascript"> function showPic(whichpic) { var source = whichpic.getAttribute("href"); var placeholder = document.getElementById("placeholder"); placeholder.setAttribute("src",source); } </script> Any help is greatly appreciated and thanks in advance for the help.

  • javascript using 'this' in global object

    - by Marco Demaio
    What does 'this' keyword refer to when used in gloabl object? Let's say for instance we have: var SomeGlobalObject = { rendered: true, show: function() { /* I should use 'SomeGlobalObject.rendered' below, otherwise it won't work when called from event scope. But it works when called from timer scope!! How can this be? */ if(this.rendered) alert("hello"); } } Now if we call in an inline script in the HTML page: SomeGlobalObject.show(); window.setTimeout("Msg.show()", 1000); everything work ok. But if we do something like AppendEvent(window, 'load', Msg.show); we get an error because this.rendered is undefined when called from the event scope. Do you know why this happens? Could you explain then if there is another smarter way to do this without having to rewrite every time "SomeGlobalObject.someProperty" into the the SomeGlobalObject code? Thanks! AppendEvent is just a simple cross-browser function to append an event, code below, but it does not matter in order to answer the above questions. function AppendEvent(html_element, event_name, event_function) { if(html_element.attachEvent) //IE return html_element.attachEvent("on" + event_name, event_function); else if(html_element.addEventListener) //FF html_element.addEventListener(event_name, event_function, false); }

  • input type text and onKeyDown not working under IE

    - by dygi
    Hi there. I am writing a WWW application, it has to run under IE. I have the problem with the code that runs under FF, but i can't get it running under IE. // JS code function test() { if (window.event.keyCpde == 13) window.location.href.ssign("myPage.php"); } I've tried some similar ways around window.location and location.href, also document.location. I've read that IE has problems with that, so i ask for a solution. The goal is, that page reloads after typing in some text into <input type='text' name='item_code' onKeyDown='test()'> and click enter. So the result is similar to pressing submit type button below the text input. Within IE it reloads the same page and nothing happens. In FF it correctly works.

  • SPARC M7 Chip - 32 cores - Mind Blowing performance

    - by Angelo-Oracle
    The M7 Chip Oracle just announced its Next Generation Processor at the HotChips HC26 conference. As the Tech Lead in our Systems Division's Partner group, I had a front row seat to the extraordinary price performance advantage of Oracle current T5 and M6 based systems. Partner after partner tested  these systems and were impressed with it performance. Just read some of the quotes to see what our partner has been saying about our hardware. We just announced our next generation processor, the M7. This has 32 cores (up from 16-cores in T5 and 12-cores in M6). With 20 nm technology  this is our most advanced processor. The processor has more cores than anything else in the industry today. After the Sun acquisition Oracle has released 5 processors in 4 years and this is the 6th.  The S4 core  The M7 is built using the foundation of the S4 core. This is the next generation core technology. Like its predecessor, the S4 has 8 dynamic threads. It increases the frequency while maintaining the Pipeline depth. Each core has its own fine grain power estimator that keeps the core within its power envelop in 250 nano-sec granularity. Each core also includes Software in Silicon features for Application Acceleration Support. Each core includes features to improve Application Data Integrity, with almost no performance loss. The core also allows using part of the Virtual Address to store meta-data.  User-Level Synchronization Instructions are also part of the S4 core. Each core has 16 KB Instruction and 16 KB Data L1 cache. The Core Clusters  The cores on the M7 chip are organized in sets of 4-core clusters. The core clusters share  L2 cache.  All four cores in the complex share 256 KB of 4 way set associative L2 Instruction Cache, with over 1/2 TB/s of throughput. Two cores share 256 KB of 8 way set associative L2 Data Cache, with over 1/2 TB/s of throughput. With this innovative Core Cluster architecture, the M7 doubles core execution bandwidth. to maximize per-thread performance.  The Chip  Each  M7 chip has 8 sets of these core-clusters. The chip has 64 MB on-chip L3 cache. This L3 caches is shared among all the cores and is partitioned into 8 x 8 MB chunks. Each chunk is  8-way set associative cache. The aggregate bandwidth for the L3 cache on the chip is over 1.6TB/s. Each chip has 4 DDR4 memory controllers and can support upto 16 DDR4 DIMMs, allowing for 2 TB of RAM/chip. The chip also includes 4 internal links of PCIe Gen3 I/O controllers.  Each chip has 7 coherence links, allowing for 8 of these chips to be connected together gluelessly. Also 32 of these chips can be connected in an SMP configuration. A potential system with 32 chips will have 1024 cores and 8192 threads and 64 TB of RAM.  Software in Silicon The M7 chip has many built in Application Accelerators in Silicon. These features will be exposed to our Software partners using the SPARC Accelerator Program.  The M7  has built-in logic to decompress data at the speed of memory access. This means that applications can directly work on compressed data in memory increasing the data access rates. The VA Masking feature allows the use of part of the virtual address to store meta-data.  Realtime Application Data Integrity The Realtime Application Data Integrity feature helps applications safeguard against invalid, stale memory reference and buffer overflows. The first 4-bits if the Pointer can be used to store a version number and this version number is also maintained in the memory & cache lines. When a pointer accesses memory the hardware checks to make sure the two versions match. A SEGV signal is raised when there is a mismatch. This feature can be used by the Database, applications and the OS.  M7 Database In-Memory Query Accelerator The M7 chip also includes a In-Silicon Query Engines.  These accelerate tasks that work on In-Memory Columnar Vectors. Oracle In-Memory options stores data in Column Format. The M7 Query Engine can speed up In-Memory Format Conversion, Value and Range Comparisons and Set Membership lookups. This engine can work on Compressed data - this means not only are we accelerating the query performance but also increasing the memory bandwidth for queries.  SPARC Accelerated Program  At the Hotchips conference we also introduced the SPARC Accelerated Program to provide our partners and third part developers access to all the goodness of the M7's SPARC Application Acceleration features. Please get in touch with us if you are interested in knowing more about this program.

  • Can this be considered Clean Code / Best Practice?

    - by MRFerocius
    Guys, How are you doing today? I have the following question because I will follow this strategy for all my helpers (to deal with the DB entities) Is this considered a good practice or is it going to be unmaintainable later? public class HelperArea : AbstractHelper { event OperationPerformed<Area> OnAreaInserting; event OperationPerformed<Area> OnAreaInserted; event OperationPerformed<Area> OnExceptionOccured; public void Insert(Area element) { try { if (OnAreaInserting != null) OnAreaInserting(element); DBase.Context.Areas.InsertOnSubmit(new AtlasWFM_Mapping.Mapping.Area { areaDescripcion = element.Description, areaNegocioID = element.BusinessID, areaGUID = Guid.NewGuid(), areaEstado = element.Status, }); DBase.Context.SubmitChanges(); if (OnAreaInserted != null) OnAreaInserted(element); } catch (Exception ex) { LogManager.ChangeStrategy(LogginStrategies.EVENT_VIEWER); LogManager.LogError(new LogInformation { logErrorType = ErrorType.CRITICAL, logException = ex, logMensaje = "Error inserting Area" }); if (OnExceptionOccured != null) OnExceptionOccured(elemento); } } I want to know if it is a good way to handle the event on the Exception to let subscribers know that there has been an exception inserting that Area. And the way to log the Exception, is is OK to do it this way? Any suggestion to make it better?

I simply changed the default <Grid /> to <Canvas /> and added a KeyDown handler that pops a MessageBox. But no matter how I tried, the KeyDown event just would never, ever fires. Is it simply that <Canvas /> doesn't support KeyDown or am I doing something wrong?
