  • ASP.NET MVC Ajax OnBegin/Complete Javascript Problem

    - by mrkcsc
    Hello, I am trying to fire off a javascript method using the OnBegin AjaxOption in an Ajax method. However, when debugging with firebug the callback in unable to find the Javascript method and I do not know why. My code is simple, first I use a basic Ajax method like this: <%= Ajax.ActionLink("Testing", "Testing", new AjaxOptions { OnBegin = "RunThisThing" }) % Then under it I decalre this script. <script type="text/javascript"> function RunThisThing { alert("WORK") } </script> Yet when I try running the page and clicking on the link, Firebug tells me "RunThisThing is not defined". Any idea what I might be doing wrong?

  • Java: Infinite loop using Scanner in.hasNextInt()

    - by Tomek
    Hi everyone, I am using the following code: while (invalidInput) { // ask the user to specify a number to update the times by System.out.print("Specify an integer between 0 and 5: "); if (in.hasNextInt()) { // get the update value updateValue = in.nextInt(); // check to see if it was within range if (updateValue >= 0 && updateValue <= 5) { invalidInput = false; } else { System.out.println("You have not entered a number between 0 and 5. Try again."); } } else { System.out.println("You have entered an invalid input. Try again."); } } However, if I enter a 'w' it will tell me "You have entered invalid input. Try Again." and then it will go into an infinite loop showing the text "Specify an integer between 0 and 5: You have entered an invalid input. Try again." Why is this happening? Isn't the program supposed to wait for the user to input and press enter each time it reaches the statement: if (in.hasNextInt()) Thanks in advance, Tomek

  • pass object from JS to PHP and back

    - by Radu
    This is something that I don't think can't be done, or can't be done easy. Think of this, You have an button inside a div in HTML, when you click it, you call a php function via AJAX, I would like to send the element that start the click event(or any element as a parameter) to PHP and BACK to JS again, in a way like serialize() in PHP, to be able to restore the element in JS. Let me give you a simple example: PHP: function ajaxCall(element){ return element; } JS: callbackFunction(el){ el.color='red'; } HTML: <div id="id_div"> <input type="button" value="click Me" onClick="ajaxCall(this, callbackFunction);" /> </div> So I thing at 3 methods method 1. I can give each element in the page an ID. so the call to Ajax would look like this: ajaxCall(this.id, callbackFunction); and the callback function would be: document.getElementById(el).color='red'; This method I think is hard, beacause in a big page is hard to keep track of all ID's. method 2. I think that using xPath could be done, If i can get the exact path of an element, and in the callback function evaluate that path to reach the element. This method needs some googling, it is just an ideea. method 3. Modify my AJAX functions, so it retain the element that started the event, and pass it to the callback function as argument when something returns from PHP, so in my AJAX would look like this: eval(callbackFunction(argumentsFromPhp, element)); and the callback function would be: callbackFunction(someArgsFromPhp, el){ el.color='red'; // parse someArgsFromPhp } I think that the third option is my choise to start this experiment. Any of you has a better idea how I can accomplish this ? Thank you.

  • Learning PHP: Good examples of "build-this" based lessons?

    - by DavidR
    Last summer I learned HTML and CSS for a job, mainly through tutorials and a sort of "build this" method, that is, I'm given a goal and have to try to figure out how to build it myself. Is there a place with some examples to teach someone with this method? My boss wants to get me going on PHP this summer, and I need to refamiliarize myself with it over the next week. Most people send me to Php.net to follow the documentation, is there another good method out there?

  • Getting started with nbehave

    - by dotnetdev
    Hi, I am looking at using BDD, however, when evaluating the stories/conditions I write (using nBehave), how do I check if the story passes? Do I write another library with test methods? For example, if I want to test a site for having a link called "About", do I write a method which can check this and then another method in another class library which can call the method to check the link via lambda syntax and add the relevant test and bdd attributes? Thanks

  • Java: easiest way to package both Java 1.5 and 1.6 code

    - by WizardOfOdds
    I want to package a piece of code that absolutely must run on Java 1.5. There's one part of the code where the program can be "enhanced" if the VM is an 1.6 VM. Basically it's this method: private long[] findDeadlockedThreads() { // JDK 1.5 only supports the findMonitorDeadlockedThreads() // method, so you need to comment out the following three lines if (mbean.isSynchronizerUsageSupported()) return mbean.findDeadlockedThreads(); else return mbean.findMonitorDeadlockedThreads(); } What would be easiest way to have this compile on 1.5 and yet do the 1.6 method calls when on 1.6 ? In the past I've done something similar by compiling a unique 1.6 class that I would package with my app and instantiate using a ClassLoader when on 1.6 (because an 1.6 JVM is perfectly fine mixing 0x32 and 0x31 classes), but I think it's a bit overkill (and a bit painful because during the build process you have to build both 0x31 and 0x32 .class files). How should I go if I wanted to compile the above method on 1.5? Maybe using reflection but then how (I'm not familiar at all with reflection) Note: if you're curious, the above method comes from this article: http://www.javaspecialists.eu/archive/Issue130.html (but I don't want to "comment the three lines" like in the article, I want this to compile and run on both 1.5 and 1.6)

  • I need to get form data from multiple forms on one page using $_POST

    - by CDeanMartin
    My project is a menu that displays daily specials at a cafe. The Pointy Haired Boss(PHB) needs to add/remove items from the menu on a daily basis, so I stored all dishes with MySQL, and created a page which will load all menu items as buttons. When clicked, the button will UPDATE the item, turning it on or off. I need form data to detect which button was pressed, so my query knows which $menuItem to UPDATE. That is the purpose of the hidden fields. <html><head></head> <body> <html><head></head> <body> <?php include("getElement.php"); $keys = array_keys($_POST); echo $keys[0]; echo $keys[1]; //if(isset($_POST["menuItem"])){ //toggleItem($_POST["menuItem"]); //echo print_r(array_keys($_POST));} ?> <form name="b" action="scratchpad.php" method="post" > <input type="hidden" name="b" value="Cajun Gumbo"/> <input type="submit" style="color:blue" value="Cajun Gumbo" /> </form> <form name="a" action="scratchpad.php" method="post" > <input type="hidden" name="a" value="Guacomole Burger"/> <input type="submit" style="color:blue" value="Guacomole Burger" /> </form> </body> </html> Can I get $_POST to identify which button was pressed?

  • generating images with php based on css3 gradient settings?

    - by thrice801
    Hi, Does anyone know if there is a php library, or if there isnt, have any input on how one would go about generating an image via php, from basic HTML element input settings, and CSS 3 gradient parameters. To give an example on why this would be useful, I have found as of a couple days ago, that laying out the wireframe for a webpage using basic Css3 gradient styling speeds up my design and development time by, well, alot. I cant design from photoshop, Ill spend hours tweaking stupid little things that only lead to me tweaking more stupid little things to compensate for stupid little changes. -- So, I had an epiphany to stop using photoshop until the end, and just focus on the main styling of elements, text-shadow, and borders for highlights, and I feel I am able to make super clean, more focused layout by being more restricted to the basics of graphic design with just css. Anyways, so Im planning on after I have the layouts done, to then recreate the graphics in photoshop, so that every browser is able to render the images. This wont take long, but as far as repeating it goes, if I could just do it with PHP, that would be incredible. For instance, take this style for example, which renders a clean looking ipad/pod ish menu/button gradient. [code] background: -moz-linear-gradient(top, #808080, #454545 50%, #313131 51%, #333333); background: -webkit-gradient(linear, left top, left bottom, color-stop(0, #808080), color-stop(.5, #454545), color-stop(.5, #313131), to(#333333));[/code] Basically what Im looking to do is take one or more inputs that control rendering the image as you see there. Take a width and a height input, and then render the image gradient accordingly, so I can save it, upload it and then use it in my designs. So ya, I know PHP has some image generation capabilities but I dont know to what extent, any input on the most effective way to go about doing this or whether it already exists, would be appreciated!

  • Java hangs when trying to close a ProcessBuilder OutputStream

    - by Jeff Bullard
    I have the following Java code to start a ProcessBuilder, open an OutputStream, have the process write a string to an OutputStream, and then close the OutputStream. The whole thing hangs indefinitely when I try to close the OutputStream. This only happens on Windows, never on Mac or Linux. Some of the related questions seem to be close to the same problem I'm having, but I haven't been able to figure out how to apply the answers to my problem, as I am a relative newbie with Java. Here is the code. You can see I have put in a lot of println statements to try to isolate the problem. System.out.println("GenMic trying to get the input file now"); System.out.flush(); OutputStream out = child.getOutputStream(); try { System.out.println("GenMic getting ready to write the input file to out"); System.out.flush(); out.write(intext.getBytes()); System.out.println("GenMic finished writing to out"); System.out.flush(); out.close(); System.out.println("GenMic closed OutputStream"); System.out.flush(); } catch (IOException iox) { System.out.println("GenMic caught IOException 2"); System.out.flush(); String detailedMessage = iox.getMessage(); System.out.println("Exception: " + detailedMessage); System.out.flush(); throw new RuntimeException(iox); } And here is the output when this chunk is executed: GenMic trying to get the input file now GenMic getting ready to write the input file to out GenMic finished writing to out

  • Code Golf: Rotating Maze

    - by trinithis
    Code Golf: Rotating Maze Make a program that takes in a file consisting of a maze. The maze has walls given by '#'. The maze must include a single ball, given by a 'o' and any number of holes given by a '@'. The maze file can either be entered via command line or read in as a line through standard input. Please specify which in your solution. Your program then does the following: 1: If the ball is not directly above a wall, drop it down to the nearest wall. 2: If the ball passes through a hole during step 1, remove the ball. 3: Display the maze. 4: If there is no ball in the maze, exit. 5: Read a line from the standard input. Given a 1, rotate the maze counterclockwise. Given a 2, rotate the maze clockwise. Rotations are done by 90 degrees. It is up to you to decide if extraneous whitespace is allowed. If the user enters other inputs, repeat this step. 6: Goto step 1. You may assume all input mazes are closed. Note, a hole effectively acts as a wall in this regard. You may assume all input mazes have no extraneous whitespace. The shortest source code by character count wins. Example mazes: ###### #o @# ###### ########### #o # # ####### # ###@ # ######### ########################### # # # # @ # # # # ## # # ####o#### # # # # # # ######### # @ ######################

  • How do I get Bison/YACC to not recognize a command until it parses the whole string?

    - by chucknelson
    I have some bison grammar: input: /* empty */ | input command ; command: builtin | external ; builtin: CD { printf("Changing to home directory...\n"); } | CD WORD printf("Changing to directroy %s\n", $2); } ; I'm wondering how I get Bison to not accept (YYACCEPT?) something as a command until it reads ALL of the input. So I can have all these rules below that use recursion or whatever to build things up, which either results in a valid command or something that's not going to work. One simple test I'm doing with the code above is just entering "cd mydir mydir". Bison parses CD and WORD and goes "hey! this is a command, put it to the top!". Then the next token it finds is just WORD, which has no rule, and then it reports an error. I want it to read the whole line and realize CD WORD WORD is not a rule, and then report an error. I think I'm missing something obvious and would greatly appreciate any help - thanks! Also - I've tried using input command NEWLINE or something similar, but it still pushes CD WORD to the top as a command and then parses the extra WORD separately.

  • Switching from form_for to remote_form_for problems with submit changes in Rails

    - by Matthias Günther
    Hi there, another day with Rails and today I want to use Ajax. linkt_remote_link for changing a text was pretty easy so I thought it would also be easy to switch my form_for loop just to an ajax request form with remote_form_for, but the problem with the remote_form_for is that it doesn't save my changes? Here the code that worked: <% form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> Here the code which don't save me the changes and submit them: <% remote_form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post" onsubmit="$.ajax({data:$.param($(this).serializeArray()), dataType:'script', type:'post', url:'/adminbill/update/58'}); return false;"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> I don't know if I have to consider something special when using remote_form_for (see remote_form_for)

  • Rails3. How do I display two different objects in a search?

    - by JZ
    I am using a simple search that displays search results: @adds = Add.search(params[:search]) In addition to the search results I'm trying to utilize a method, nearbys(), which displays objects that are close in proximity to the search result. The following method displays objects which are close to 2, but it does not display object 2. How do I display object 2 in conjunction with the nearby objects? @adds = Add.find(2).nearbys(10) While the above code functions, when I use search, @adds = Add.search(params[:search]).nearbys(10) a no method error is returned, undefined methodnearbys' for Array:0x30c3278` How can I search the model for an object AND use the nearbys() method AND display all results returned?

  • Start thread with two parameters

    - by Matt
    I've got a method that gets called on an event, which presents me with two variables varA, varB (both strings). This method gets called with new information quite frequently, thus I have created a separate method that takes in the two parameters. I want to run this method in a thread, however have struck the issue that Thread.Start will not accept parameters. I've tried a few supposed methods, but have so far had no luck.. I think my best bet is to create a separate class, and handle it there.. However I have a List which I am inserting data into, and hit a dead end when the separate class tried to access that list, since it was in a different class. Can someone help me out here please?

  • split line of text

    - by plys
    Hi all, I was wondering if there is an algorithm to split a line into multiple lines, so that the resulting set of multiple lines fit into a square shape rather than a rectangle. Let me give some examples, Input: Hi this is a really long line. Output: Hi this is a really long line Input: a b c d e f Output: a b c d e f Input: This is really such looooooooooooooooooooong line.This is the end. Output: This is really such looooooooooooooooooooong line This is the end. If you see in the above examples, input line fits into a wide rectangle. But the output more or less fits into a square shape. Essentially what needs to be done here is simply count the number of characters in the line, take the square root of that number. Then put square root number of characters in each line. But in the above example, the splitting needs to be done by respecting word wraps instead of characters. Is there any standard algorithm for this? Any code examples/ pointers would be appreciated!

  • How can I display multiple django modelformset forms together?

    - by JT
    I have a problem with needing to provide multiple model backed forms on the same page. I understand how to do this with single forms, i.e. just create both the forms call them something different then use the appropriate names in the template. Now how exactly do you expand that solution to work with modelformsets? The wrinkle, of course, is that each 'form' must be rendered together in the appropriate fieldset. For example I want my template to produce something like this: <fieldset> <label for="id_base-0-desc">Home Base Description:</label> <input id="id_base-0-desc" type="text" name="base-0-desc" maxlength="100" /> <label for="id_likes-0-icecream">Want ice cream?</label> <input type="checkbox" name="likes-0-icecream" id="id_likes-0-icecream" /> </fieldset> <fieldset> <label for="id_base-1-desc">Home Base Description:</label> <input id="id_base-1-desc" type="text" name="base-1-desc" maxlength="100" /> <label for="id_likes-1-icecream">Want ice cream?</label> <input type="checkbox" name="likes-1-icecream" id="id_likes-1-icecream" /> </fieldset> I am using a loop like this to process the results for base_form, likes_form in map(None, base_forms, likes_forms): which works as I'd expect (I'm using map because the # of forms can be different). The problem is that I can't figure out a way to do the same thing with the templating engine. The system does work if I layout all the base models together then all the likes models after wards, but it doesn't meet the layout requirements.
