  • JQuery: show div on radiobutton select

    - by nav
    Hi, I am trying to use JQuery to show a div when the user selects a particular radio button (Other) within a radiobutton group. The html is below <div id="countries"> <input id="Washington_D.C" TYPE="RADIO" NAME="location" VALUE="Washington">Washington D.C</input> <input id="Other" TYPE="RADIO" NAME="location" VALUE="">Other</input> <div id="other locations" style="display: none"> </div> </div> Using the JQuery code: $(document).ready(function(){ $("radio[@name='location']").change(function(){ if ($("radio[@name='location']:checked").val() == 'Other') $("#county_drop_down").show(); }); }); But its not showing the div 'other locations' when I select the radiobutton'Other'....

  • How Can I switch the session storage according to the client on Ruby on Rails 2.3.5

    - by mojalin
    Hi! I have a question about sessions on ruby-on-rails. We have a several options about session storage such as cookie, active_record_store, etc.. I primarily use the cookie storage, but, there are some client which doesn't support cookie function. In that case, I have to make that client to use the "active_record_store". My rails version is 2.3.5. I found out that even though I use the active_record_store, the cookie is still available. In my situation, both session storage might be available. So, I want to make the framework to primarily use the cookie, when the cookie is available. On the other hand, the client doesn't support the cookie, secondly to use the active_record_store. I think this function requires some override to the framework, but I don't know how to do it. Do you have any idea for that? Thank you very much in advance.

  • java System.nanoTime is really slow. Is it possible to implement a high performance java profiler?

    - by willpowerforever
    I did a test and found the overhead of a function call to System.nanoTime() is at least 500 ns on my machine. Seemed that it is very hard to have a high performance java profiler. For enterprise software, suppose a function takes about 350 seconds and has 12,500,000,000 times of method calls. Therefore, the number of calls to System.nanoTime() is: 12,500,000,000 * 2 = 25,000,000,000 (one for start timestamp, one for end timestamp) And the overhead of System.nanoTime in total is: 500 ns * 25,000,000,000 = 500 * 25000 s = 12500000s. Note: all data from real case. Any better way to acquire the timestamp?

  • Returning mySQL error with jQuery & AJAX

    I've got a form inserting data into mySQL. It works but I'm trying to add error handling in case something happens.

  • MySQL triggers cannot update rows in same table the trigger is assigned to. Suggested workaround?

    - by Cory House
    MySQL doesn't currently support updating rows in the same table the trigger is assigned to since the call could become recursive. Does anyone have suggestions on a good workaround/alternative? Right now my plan is to call a stored procedure that performs the logic I really wanted in a trigger, but I'd love to hear how others have gotten around this limitation. Edit: A little more background as requested. I have a table that stores product attribute assignments. When a new parent product record is inserted, I'd like the trigger to perform a corresponding insert in the same table for each child record. This denormalization is necessary for performance. MySQL doesn't support this and throws: Can't update table 'mytable' in stored function/trigger because it is already used by statement which invoked this stored function/trigger. A long discussion on the issue on the MySQL forums basically lead to: Use a stored proc, which is what I went with for now. Thanks in advance!

  • Using jQuery's animate(), if the clicked on element is "<a href="#" ...> </a>", the fucntion should

    - by Jian Lin
    I was reading jQuery's page for animate() http://api.jquery.com/animate/ Its examples don't mention about if using <a href="#" id="clickme">click me</a> ... $('#clickme').click(function() { $('#someDiv').animate({left: "+=60"}); }) we actually still have to return false like in the old days? $('#clickme').click(function() { $('#someDiv').animate({left: "+=60"}); return false; }) (but then, those examples didn't use a <a> for the "click me"... but used something else. Otherwise the page will jump back to the beginning of the page? Does jQuery have a more elegant or magical way of doing it?

  • How should I port this Prototype to JQuery?

    - by blu
    There is currently this Prototype code that does a PUT: new Ajax.Request(someUrl, { method: 'put', parameters: { 'foo': bar }, onSuccess: function(response) { } .bind(this) }); I found this post but the solution uses an extra parameter supported by RoR, however I am targeting an ASP.NET backend. I searched a bit and found that not all browsers support PUT operations so apparently this could fail in certain browsers? This is already in prod, so a direct port would be fine for now I suppose. As an aside, what is the deal with the bind(this) in the onSuccess function?

  • Speed up the loop operation in R

    - by Kay
    Hi, i have a big performance problem in R. I wrote a function that iterates over an data.frame object. It simply adds a new col to a data.frame and accumulate sth. (simple operation). The data.frame has round about 850.000 rows. My PC is still working about 10h now and i have no idea about the runtime. dayloop2 <- function(temp){ for (i in 1:nrow(temp)){ temp[i,10] <- i if (i > 1) { if ((temp[i,6] == temp[i-1,6]) & (temp[i,3] == temp[i-1,3])) { temp[i,10] <- temp[i,9] + temp[i-1,10] } else { temp[i,10] <- temp[i,9] } } else { temp[i,10] <- temp[i,9] } } names(temp)[names(temp) == "V10"] <- "Kumm." return(temp) } Any ideas how to speed up this operation ?

  • Simaltaneous connections with PHP and SOAP?

    - by Dov
    I'm new to using SOAP and understanding the utmost basics of it. I create a client resource/connection, I then run some queries in a loop and I'm done. The issue I am having is when I increase the iterations of the loop, ie: from 100 to 1000, it seems to run out of memory and drops an internal server error. How could I possibly run either a) multiple simaltaneous connections or b) create a connection, 100 iterations, close connection, create connection.. etc. "a)" looks to be the better option but I have no clue as to how to get it up and running whilst keeping memory (I assume opening and closing connections) at a minimum. Thanks in advance! index.php <?php // set loops to 0 $loops = 0; // connection credentials and settings $location = 'https://theconsole.com/'; $wsdl = $location.'?wsdl'; $username = 'user'; $password = 'pass'; // include the console and client classes include "class_console.php"; include "class_client.php"; // create a client resource / connection $client = new Client($location, $wsdl, $username, $password); while ($loops <= 100) { $dostuff; } ?> class_console.php <?php class Console { // the connection resource private $connection = NULL; /** * When this object is instantiated a connection will be made to the console */ public function __construct($location, $wsdl, $username, $password, $proxyHost = NULL, $proxyPort = NULL) { if(is_null($proxyHost) || is_null($proxyPort)) $connection = new SoapClient($wsdl, array('login' => $username, 'password' => $password)); else $connection = new SoapClient($wsdl, array('login' => $username, 'password' => $password, 'proxy_host' => $proxyHost, 'proxy_port' => $proxyPort)); $connection->__setLocation($location); $this->connection = $connection; return $this->connection; } /** * Will print any type of data to screen, where supported by print_r * * @param $var - The data to print to screen * @return $this->connection - The connection resource **/ public function screen($var) { print '<pre>'; print_r($var); print '</pre>'; return $this->connection; } /** * Returns a server / connection resource * * @return $this->connection - The connection resource */ public function srv() { return $this->connection; } } ?>

  • jQuery: modify hidden form field value before submit

    - by Jason Miesionczek
    I have the following code in a partial view (using Spark): <span id="selectCount">0</span> video(s) selected. <for each="var video in Model"> <div style="padding: 3px; margin:2px" class="video_choice" id="${video.YouTubeID}"> <span id="video_name">${video.Name}</span><br/> <for each="var thumb in video.Thumbnails"> <img src="${thumb}" /> </for> </div> </for> # using(Html.BeginForm("YouTubeVideos","Profile", FormMethod.Post, new { id = "youTubeForm" })) # { <input type="hidden" id="video_names" name="video_names" /> <input type="submit" value="add selected"/> # } <ScriptBlock> $(".video_choice").click(function() { $(this).toggleClass('selected'); var count = $(".selected").length; $("#selectCount").html(count); }); var options = { target: '#videos', beforeSubmit: function(arr, form, opts) { var names = []; $(".selected").each(function() { names[names.length] = $(this).attr('id'); }); var namestring = names.join(","); $("#video_names").attr('value',namestring); //alert(namestring); //arr["video_names"] = namestring; //alert($.param(arr)); //alert($("#video_names").attr('value')); return true; } }; $("#youTubeForm").ajaxForm(options); </ScriptBlock> Essentially i display a series of divs that contain information pulled from the YouTube API. I use jQuery to allow the the user to select which videos they would like to add to their profile. When i submit the form i would like to populate the hidden field with a comma separated list of video ids. Everything works except that when i try to set the value of the field, in the controller on post, the field comes back empty. I am using the jQuery ajax form plugin. What am i doing wrong that is not allowing the value i set in the field to be sent to the server?

  • Joining links together in a dictionary

    Hi guys, I'm student here, new to python and programming in general. I have a dictionary links which holds a tuple mapped to a number. How can I join the second url in the second tuple together with the urljoin() function? What I'm trying to do is get complete links so I can run a recursive function search() which takes a complete url as an arguement, finds all the links in each url and stores the number of links mapped to the links in a database. So far, I have: links {('href', 'http://reed.cs.depaul.edu/lperkovic/csc242/test2.html'): 1, ('href', 'test3.html'): 1} I want http://reed.cs.depaul.edu/lperkovic/csc242/test3.html...

  • Anchoring the Action URL of a Form

    - by John
    Hello, I am using a function that leads users to a file called "comments2.php": <form action="http://www...com/.../comments/comments2.php" method="post"> On comments2.php, data passed over from the form is inserted into MySQL: $query = sprintf("INSERT INTO comment VALUES (NULL, %d, %d, '%s', NULL)", $uid, $subid, $comment); mysql_query($query) or die(mysql_error()); Then, later in comments2.php, I am using a query that loops through entries meeting certain criteria. The loop contains a row with the following information: echo '<td rowspan="3" class="commentname1" id="comment-' . $row["commentid"] . '">'.stripslashes($row["comment"]).'</td>'; For the function above, I would like the URL to be anchored by the highest value of "commentid" for id="comment-' . $row["commentid"] . '" How can this be done? Thanks in advance, John

  • Performance tweaks and upgrades for VMWare Server 2

    - by sjohnston
    Our software department has a server running VMWare Server 2. We typically have 8-10 VMs running as test environments (Win XP and Server 08) for various versions of our software, and one VM that is used as a build server (Win XP). The host is running Server 2003 R2. It has 32GB RAM, 8 core Xeon 3.16GHz CPU, one disk for host OS and two raid disks for VMs. The majority of the time, this setup behaves very well and there are no complaints. Other times, the VMs can be very laggy. This is sometimes, but not always, correlated to heavy load on the build server. I'm a software developer, not an IT pro, but it seems to me that this machine should be beefy enough to handle this many VMs. Is this occasional performance hit likely just because we're hitting the limits of the hardware, or should I be looking for another culprit? From what I've read, I'm guessing if there's a bottleneck, it's probably disk I/O with all these VMs running off two disks (especially the build server). Would spreading the VMs over more disks, and/or switching to SSDs give us a significant performance boost? Other things I've read may increase performance: single virtual processor per VM removing/disabling unused virtual hardware preallocated disk space not using snapshots setting a reserved memory limit on the host and disabling VM memory swapping Can anyone confirm or deny if any of these improve performance? What other good tweaks have I missed?

  • Get scrollheight cross-browser through Selenium

    - by hh354
    Hi, I'm working on a project which is using Selenium and I'd like to try to get the full web page height cross-browser and cross-platform. IE8 is being stubborn as always, is there anybody who has an idea of how to solve this? The problem: When you scroll down a page for e.g. 500px and you keep doing this until the bottom of the page, the last scroll will be less than 500px. I need to know how much this last scroll was. Two ways of solving: 1) Find the offset that has been scrolled each time (works everywhere except IE8) 2) Find the total height of the webpage I know JQuery's height() function does this but I can't use this function from Selenium RC. If you know a way of calling JQuery functions through Selenium or any other solution, please tell! Cheers, Henry

    I am trying to show and hide an inline element (eg a span) using jquery. If I just use toggle(), it works as expected but if I use toggle("slow") to give it an animation, it turns the span into a block element and therefore inserts breaks.

  • Linking to a C library compiled as C++

    - by Jacob
    I'm in linker paradise now. I have a C library which only compiles in Visual C++ (it probably works in gcc) if: I compile it as C++ code Define __cplusplus which results in all the declarations being enclosed in extern "C" { } So, by doing this I have a static library called, say, bsbs.lib Now, I have a C++ project called Tester which would like to call function barbar in declared in bsbs.h. All goes fine, until I try to link to bsbs.lib where I get the all-too-familiar: Tester.obj : error LNK2001: unresolved external symbol _foofoo And it always seems to be foofoo which cannot be resolved regardless of which function I call in Tester (barbar or anything else).

  • Are there any Python reference counting/garbage collection gotchas when dealing with C code?

    - by Jason Baker
    Just for the sheer heck of it, I've decided to create a Scheme binding to libpython so you can embed Python in Scheme programs. I'm already able to call into Python's C API, but I haven't really thought about memory management. The way mzscheme's FFI works is that I can call a function, and if that function returns a pointer to a PyObject, then I can have it automatically increment the reference count. Then, I can register a finalizer that will decrement the reference count when the Scheme object gets garbage collected. I've looked at the documentation for reference counting, and don't see any problems with this at first glance (although it may be sub-optimal in some cases). Are there any gotchas I'm missing? Also, I'm having trouble making heads or tails of the cyclic garbage collector documentation. What things will I need to bear in mind here? In particular, how do I make Python aware that I have a reference to something so it doesn't collect it while I'm still using it?

  • F# Extention Methods on Lists, IEnumberable, etc

    - by flevine100
    I have searched StackOverflow (and other sources) for this answer, but can't seem to find anything. In C#, if I had a widget definition, say: class widget { public string PrettyName() { ... do stuff here } } and I wanted to allow for easy printing of a list of Widgets, I might do this: namespace ExtensionMethods { public static PrintAll( this IEnumerable<Widget> widgets, TextWriter writer ) { foreach(var w in widgets) { writer.WriteLine( w.PrettyName() ) } } } How would I accomplish something similar with a record type and a collection (List or Seq preferrably in F#). I'd love to have a list of Widgest and be able to call a function right on the collection that did something like this. Assume (since it's F#) that the function would not be changing the state of the collection that it's attached to, but returning some new value.

I need it to be fast, as this will be used many times in computation.

  • What is the best way to convert a hexidecimal string to a byte array (.NET)?

    - by Robert Wagner
    I have a hexidecimal string that I need to convert to a byte array. The best way (ie efficient and least code) is: string hexstr = "683A2134"; byte[] bytes = new byte[hexstr.Length/2]; for(int x = 0; x < bytes.Length; x++) { bytes[x] = Convert.ToByte(hexstr.Substring(x * 2, 2), 16); } In the case where I have a 32bit value I can do the following: string hexstr = "683A2134"; byte[] bytes = BitConverter.GetBytes(Convert.ToInt32(hexstr, 16)); However what about in the general case? Is there a better built in function, or a clearer (doesn't have to be faster, but still performant) way of doing this? I would prefer a built in function as there seems to be one for everything (well common things) except this particular conversion.
