    Hi. I have this array (JQuery) where I add all my form's controls, it looks like: var name = $("#name"), surname = $("#surname"), address = $("#address"), phone = $("#phone"), photo = $("#photo"), grade = $("#grade"), profession = $("#profession"), email = $('#email'), title = $('#title'), allFields = $([]).add(name) .add(surname) .add(address) .add(phone) .add(photo) .add(grade) .add(profession) .add(email) .add(title) .add(grade); I want to check the values of each element into the 'allFields' array with function checkingFieldsArentEmpty(){ var valid = true; for (var f in allFields){ if(allFields[f].val() === null) //if any val is null just return false return false; } //true return valid; } I need ideas in order to improve the last function.

  • How do I make different texts to appear in after clicking x-times?

    - by Sebastian Lindén
    I want to show some text within a class for each click but keep the clicky-class. Shortly, if you click 2 times, you will get a div-text "You clicked two times", you will still be able to click a third time, then you will get "You clicked three times", until the fifth time when everything will hide. Is there any simpel way to do this? I tried with this but couldn't get it to work. var clicks = 0; $('.clicky').on('click', function() { clicks++; if(clicks >= 3) { $(this).add($('.background')).add($('.hello')); } else(clicks >= 5) { $(this).add($('.background')).hide(); } });? http://jsfiddle.net/sLAzY/ This is a working example of the hide function. Hope you understand what I mean Have a nice day!

  • How can I determine which dependency would cause a C++ compilation unit to be rebuilt?

    - by Seb Rose
    I have a legacy C++ application with a deep graph of #includes. Changes to any header file often cause recompiles of seemingly unrelated source files. The application is built using a Visual Studio 2005 solution (sln) file. Can MSBUILD be invoked in a way that it reports which dependency(ies) are causing a source file to be recompiled? Is there any other tool that might be able to help? NOTE: I'm only looking for a tool to tell me why a file would be rebuilt, not some restrospective magic telling me why it was rebuilt.

  • thumbs.db messing up my upload routine

    - by Scott B
    I'm getting the following error while uploading a zip archive. Warning: ZipArchive::extractTo(C:\xampplite\htdocs\testsite/wp-content/themes/mytheme//styles\mytheme/Thumbs.db) [ziparchive.extractto]: failed to open stream: Permission denied in C:\xampplite\htdocs\testsite\wp-content\themes\mythem\uploader.php on line 17 The thing I can't quite figure is that I don't see a thumbs.db file in either the zip archive or the destination folder that was created (the upload still processes, I just get these errors). The function is below, line 17 is commented... function openZip($file_to_open) { global $target; $zip = new ZipArchive(); $x = $zip->open($file_to_open); if($x === true) { $zip->extractTo($target); //this is line 17 $zip->close(); unlink($file_to_open); } else { die("There was a problem. Please try again!"); } }

  • How to move to a location in a web browser component?

    - by Mostafa Mahdieh
    I have a .NET windows form page and a WebBrowser component inside. I load a page inside the web browser using the Navigate method as in: webBrowser1.Navigate("http://www.stackoverflow.com"); The pages length is longer than the browsers height, so the vertical scroll bar appears. Now I want to move the scrollbar down to a specific position. More specifically I want to search for a specific peace of text inside the page, and scroll to that position. This behavior is implemented in the built-in "Find" function of the browser, but I can't figure out how to call the Find function from within my code, without the Find window appearing. Although I don't want the Find window to appear, if the text matches are highlighted it is welcome.

  • How to create a non-persistent Elixir/SQLAlchemy object?

    - by siebert
    Hi, because of legacy data which is not available in the database but some external files, I want to create a SQLAlchemy object which contains data read from the external files, but isn't written to the database if I execute session.flush() My code looks like this: try: return session.query(Phone).populate_existing().filter(Phone.mac == ident).one() except: return self.createMockPhoneFromLicenseFile(ident) def createMockPhoneFromLicenseFile(self, ident): # Some code to read necessary data from file deleted.... phone = Phone() phone.mac = foo phone.data = bar phone.state = "Read from legacy file" phone.purchaseOrderPosition = self.getLegacyOrder(ident) # SQLAlchemy magic doesn't seem to work here, probably because we don't insert the created # phone object into the database. So we set the id fields manually. phone.order_id = phone.purchaseOrderPosition.order_id phone.order_position_id = phone.purchaseOrderPosition.order_position_id return phone Everything works fine except that on a session.flush() executed later in the application SQLAlchemy tries to write the created Phone object to the database (which fortunatly doesn't succeed, because phone.state is longer than the data type allows), which breaks the function which issues the flush. Is there any way to prevent SQLAlchemy from trying to write such an object? Ciao, Steffen

  • Why is my form triggering the wrong controller action?

    - by COCoach
    This form has multiple submit buttons, when clicked, it calls a simple JavaScript function to change the value of a hidden input (function is called "setHidden". This worked before, after some other not relevant code, it has ceased working. Essentially, the action it is supposed to call is never called, instead it seems to default back to a previous URL. The Form: <form action="/League/RemoveOwner" method="post"> <input type="hidden" value="1007" name="lid"/> <input type="hidden" value="0" id="index" name="index"/> <input type="image" src="../../Resources/Images/Delete.png" height="12" alt="Remove Owner" title="Remove Owner" onclick="setHidden('index', '1031')"/></a> coach<br /> </form> The Controller: [HttpPost] public ActionResult RemoveOwner(int id, string index) { //yada return PartialView(); } When clicking the image, it should call the remove owner controller, instead it calls the "View" controller: public ActionResult View(int id) { //yada return View(); }

  • "Intercepting" user input into text box and removing it

    - by James P
    I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

  • does the condition after && always get evaluated

    - by brett
    I have this if statement that tests for the 2 conditions below. The second one is a function `goodToGo() so I want to call it unless the first condition is already true $value = 2239; if ($value < 2000 && goodToGo($value)){ //do stuff } function goodToGo($value){ $ret = //some processing of the value return $ret; } My question is about the 2 if conditions $value < 2000 && goodToGo($value). Do they both get evaluated or does the second one only get evaluated when the first one is true? In other words, are the following 2 blocks the same? if($value < 2000 && goodToGo($value)) { //stuff to do } if($value < 2000) { if (goodToGo($value)){ //stuff to do } }

  • In FLEX, How can you stop ENTER Key from my Alert being caught by the control that initiated the Al

    - by WeeJavaDude
    I am having an issue where I show an AlertBox message when the user hits ENTER and the focus is in a text area. The pop up works fine, but when the user hits enter the Alert closes as expected, but the TextArea listener receives the ENTER event from the Alert and pops the dialog up again. I have tried a number of ways to catch and eat the event but so far I have not been lucky. Is there way to accomplish this? public function init():void { myTextInput.addEventListener(KeyboardEvent.KEY_UP, handleKeyStrokes); } public function handleKeyStrokes(evt:KeyboardEvent):void { if(evt.keyCode == Keyboard.ENTER) { myAlert = Alert.show("This is a test and only a test", "Title", 4, null, alertCallBack); } } <mx:TextInput id="myTextInput" left="600" top="10"> </mx:TextInput>

  • Image Preloading in Canvas

    - by smokinguns
    I'm drawing an Image on the canvas using the drawImage function. This is how Im setting the src property of the image: var img = new Image(); // Create new Image object img.src = 'test.php?filename=myfile.jpg' and then oCanvas.width = 600; oCanvas.height = 400; oContext.drawImage(img, 0, 0, 600, 400); The problem is that if the src isn't set then I get the foll error:"uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMCanvasRenderingContext2D.drawImage]" . I know I get this error coz the image hasnt finished loading. I added an alert just before the call to drawImage function to let the image finish loading and it seems to work. But it's a pain in the neck. How do I check if the image has finished loading? BTW I have to set the src property by calling a php file.

  • JS Variable inside another variable

    - by Tusk
    I have a function that would use other variables, depending on what has been passed. Like this = ActionBar(slot) slot contains "one". and I would like to create a call inside that like object.slot.name but it should convert it before hand to make the command look like object.one.name. Is there a way to do this in javascript/jquery? I remember vaguely that some other language does this as {slot} or something like that. Sorry if this question was already asked, I've checked google and stackoverflow too, but didn't find an answer. Also I'd like to know what's the proper programming term for this kind of variable passing? Edited it cause of misunderstandings. I'm looking into OOP js, so object is an object, one is an object, and name is an attribute, but when passing I'm passing "one" as a string to the function. Tried eval, it doesn't work while dotted with an object.

  • Cannot move ckeditor 4 selection to beginning

    - by Gary Hillerson
    I've been exploring numerous solutions in stackoverflow and elsewhere to try to get ckeditor 4 to scroll to the top after I've programmatically added a number of pages to it, using CKEditor's InsertHtml function. After adding my html, which looks fine, I want to position the cursor at the beginning. Here's one of a variety of things I've tried without success: function MoveCaretToStart(myEditor) { var range = new CKEDITOR.dom.range( editor.document ); range.selectNodeContents(editor.document.getBody()); range.moveToElementEditStart(range.root); // also tried range.collapse(true); range.select(); } ... MoveCaretToStart(CKEDITOR.instances['myEditor']); // which already has contents in it This doesn't throw any errors, but also doesn't move the cursor position (it remains at the end of the doc). I thought this one would be easy, but it sure hasn't been. Any help appreciated.

  • CRC32 calculations for png chunk doesn't match the real one

    - by user2507197
    I'm attempting to mimic the function used for creating CRC's in PNG files, I'm using the autodin II polynomial and the source code from: http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/libkern/crc32.c My tests have all been for the IHDR chunk, so my parameters have been: crc - 0xffffffff and 0 (both have been suggested) buff - the address of the IHDR Chunk's type. length - the IHDR Chunk's length + 4 (the length of the chunk's data + the length of the type) I printed the calculated CRC in binary, which I compared to the actual CRC of the chunk. I can see no similarities (little-big endian, reversed bits, XOR'd, etc). This is the data for the IHDR chunk (hexadecimal format): length(big endian): d0 00 00 00 (13) type: 49 48 44 52 data: 00 00 01 77 00 00 01 68 08 06 00 00 00 existing CRC: b0 bb 40 ac If anyone can tell me why my calculations are off, or give me a CRC32 function that will work I would greatly appreciate it. Thank-you!

  • (Cocoa) Can I Subclass and Delegate at the same time?

    - by Alvin
    @interface ClassB <ClassADelegate> : ClassA id <ClassBDelegate> delegate; @end As the code says, ClassB subclasses from ClassA and handles the formation protocol of Class A. However, the variable "delegate" will be duplicated. (ClassA also has "delegate") In fact, it can be done without subclassing, but it seems the code is cumbersome, i.e., to use a variable/function of ClassA, I need to write [[ClassB classA] doSomething] instead of [classB doSomething], where doSomething: is a function of ClassA. Are there any tidy way for me to do that?

  • How do I marshal a pointer to an array of pointers to structures?

    - by Daniel Stutzbach
    I have a C function with the following signature: int my_function(int n, struct player **players) players is a pointer to an array of pointers to struct player objects. n is the number of pointers in the array. The function does not modify the array nor the contents of the structures, and it does not retain any pointers after returning. I tried the following: [DllImport("mylibary.dll")] static extern int my_function(int n, [In, MarshalAs(UnmanagedType.LPArray, SizeParamIndex = 0)] player_in []players); However, that marshals the data as a pointer to an array of structures, not a pointer to an array of pointers to structures.

I don't know why its not satisfying all the possibilities of the validation. And also i have to do is to enable the submit button after all the fields satisfy the validation. After once it enabled, if i make any error in any field it will not get disable correctly. I wrote the coding correctly i think so. Please take a look at my validation function and give me some suggestion to make it possible. Please guide me, Thanks & Regards, chocka.

  • jquery animating different img widths

    - by romeozor
    Hi there, I've been searching for an answer for a long time with no avail, so it's time to ask. I'm trying to use .animate() to change the size of an image once clicked. The first state of the image would be a thumbnail size, which would animate to the image's original size, then to a thumbnail again. The problem is, not all the images have the same "original" size so I need a way to tell one generic function to switch to the current image's original size. This is my current code which loads on $(window).load: $('img[class=resize]').click(function (){ if ($(this).width() != 150) { $(this).animate({width: '150px'}, 400); } else { $(this).animate({width: ''}, 400); } }); Now this obviously doesn't work the way I want it, because .animate() thinks when I say width: '' I want to make the width = 0. Any suggestions how I should go about this?

  • How to convert jquery collection to xml string for an ajax request

    - by Jim
    I created a jquery collection that stores xml as follows: var rh_request = $('') .attr('user_id', user_id) .attr('company_id', company_id) .attr('action', 'x'); I want to post it to my server via an ajax request as follows: $.ajax({ type: "POST", url: mywebsiteURL, processData: false, dataType: "xml", data: rh_request.html(), success: mycallbackfunction }); My problem is that the "data" parameter of the ajax call needs a string version of the xml and it seems neither Jquery's .html() or .text() function yields this. I have older code that used straight javascript to form the outgoing xml and calling the DOM .xml() function yielded a string that worked. How is this done with a jquery collection???
