  • jQuery validate plugin radio with optional text

    - by timborden
    I'm trying to figure out how to validate a form element with a mix of radio inputs and a text input: <label>Question?</label> <input type="radio" class="mandatory" name="questions[1][]" value="1" />answer 1<br/> <input type="radio" class="mandatory" name="questions[1][]" value="2" />answer 2<br/> <input class="ignore" type="radio" id="questions[1][]" />Other (please specify)<br/> <input class="optional mandatory" type="text" name="questions[1][]" value="" /> I've figured out how to get the form to behave as expected (select and unselect) with the following code: $("input.optional").focus(function () { var this_name = $(this).attr("name"); $("input:radio").filter(function() {return $(this).attr('name') == this_name; }).attr('checked', false); $("input").filter(function() {return $(this).attr('id') == this_name; }).attr('checked', true); }); $(':radio').click(function () { var this_name = $(this).attr("name"); $("input").filter(function() {return $(this).attr('id') == this_name; }).attr('checked', false); $("input.optional").filter(function() {return $(this).attr('name') == this_name; }).val(''); }); I was hoping I could use the class "mandatory" to validate the mix of radio and text inputs: $("form .manditory").each(function () { $(this).rules("add", {required: true}); }); But it's not working as expected. With the radio (id="questions[1][]") selected, and the text input containing content, the form element is still flagged as invalid. Suggestions...maybe a better approach? Thanks in advance. UPDATE Sorry, I should have clarified that I'm using the validate plugin: $("form").validate({ ... });

  • Monitor ASP.NET Session State Variables

    - by Dave Johnson
    We are running a number of ASP.NET applications on W2K3 Server and IIS 6.0, and are looking for a way to be able to monitor ASP.NET session state variables (InProc) that are stored in memory. We are thinking there may be some memory optimization opportunities with some of these session state variables potentially consuming large amounts of RAM. Is there a way to accomplish this through IIS or Windows rather than instrumenting all of the individual Web apps with code to monitor the session state variables?

  • Is there a difference between "." and "source" in bash, after all?

    - by ysap
    I was looking for the difference between the "." and "source" builtin commands and a few sources (e.g., in this discussion, and the bash manpage) suggest that these are just the same. However, following a problem with environment variables, I conducted a test. I created a file testenv.sh that contains: #!/bin/bash echo $MY_VAR In the command prompt, I performed the following: > chmod +x testenv.sh > MY_VAR=12345 > ./testenv.sh > source testenv.sh 12345 > MY_VAR=12345 ./testenv.sh 12345 [note that the 1st form returned an empty string] So, this little experiment suggests that there is a difference after all, where for the "source" command, the child environment inherits all the variables from the parent one, where for the "." it does not. Am I missing something, or is this is an undocumented/deprecated feature of bash? [ GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu) ]

  • Are local variables in Fortran 77 static or stack dynamic?

    - by mm2887
    For my programming languages class one hw problem asks: Are local variables in FORTRAN static or stack dynamic? Are local variables that are INITIALIZED to a default value static or stack dynamic? Show me some code with an explanation to back up your answer. Hint: The easiest way to check this is to have your program test the history sensitivity of a subprogram. Look at what happens when you initialize the local variable to a value and when you don’t. You may need to call more than one subprogram to lock in your answer with confidence. I wrote a few subroutines: - create a variable - print the variable - initialize the variable to a value - print the variable again Each successive call to the subroutine prints out the same random value for the variable when it is uninitialized and then it prints out the initialized value. What is this random value when the variable is uninitialized? Does this mean Fortran uses the same memory location for each call to the subroutine or it dynamically creates space and initializes the variable randomly? My second subroutine also creates a variable, but then calls the first subroutine. The result is the same except the random number printed of the uninitialized variable is different. I am very confused. Please help! Thank you so much.

  • Codeigniter - accessing variables from an array passed into a page.

    - by Matt
    Hello, I have a controller with an index function as follows: function index() { $this->load->model('products_model'); $data['product'] = $this->products_model->get(3); // 3 = product id $data['product_no'] = 3; $data['main_content'] = 'product_view'; //print_r($data['products']); $this->load->view('includes/template', $data); } This is the get function in the products_model file function get($id) { $results = $this->db->get_where('products', array('id' => $id))->result(); //get the first item $result = $results[0]; return $result; } The products table contains fields such as name, price etc. Please can you tell me how to output variables from $data['product'] after it is passed into the view? I have tried so many things but nothing is working, even though the print_r (commented out) shows the data - it is not being passed into the view. I thought it may have been because the view calls a template file which references the main_content variable: Template file contents: <?php $this->load->view('includes/header'); ?> <?php $this->load->view($main_content); ?> <?php $this->load->view('includes/footer'); ?> but i tried creating a flat view file and still couldn't access the variables. Many thanks,

  • C# return variables

    - by pb01
    In a debate regarding return variables, some members of the team prefer a method to return the result directly to the caller, whereas others prefer to declare a return variable that is then returned to the caller (see code examples below) The argument for the latter is that it allows a developer that is debugging the code to find the return value of the method before it returns to the caller thereby making the code easier to understand: This is especially true where method calls are daisy-chained. Are there any guidelines as to which is the most efficient and/or are there any other reasons why we should adopt one style over another? Thanks private bool Is2(int a) { return a == 2; } private bool Is3(int a) { var result = a == 3; return result; }

  • Algorithm for optimal combination of two variables

    - by AlanChavez
    I'm looking for an algorithm that would be able to determine the optimal combination of two variables, but I'm not sure where to start looking. For example, if I have 10,000 rows in a database and each row contains price, and square feet is there any algorithm out there that will be able to determine what combination of price and sq ft is optimal. I know this is vague, but I assume is along the lines of Fuzzy logic and fuzzy sets, but I'm not sure and I'd like to start digging in the right field to see if I can come up with something that solves my problem.

  • Optional one-to-one mapping in Hibernate

    - by hibernate
    How do I create an optional one-to-one mapping in the hibernate hbm file? For example, suppose that I have a User and a last_visited_page table. The user may or may not have a last_visited page. Here is my current one-to-one mapping in the hbm file: User Class: <one-to-one name="lastVisitedPage" class="LastVisitedPage" cascade="save-update"> LastVisitedPage Class: <one-to-one name="user" class="user" constrained="true" /> The above example does not allow the creation of a user who does not have a last visited page. A freshly created user has not visited any pages yet. How do I change the hbm mapping to make the userPrefs mapping optional?

  • Django Formset validation with an optional ForeignKey field

    - by Camilo Díaz
    Having a ModelFormSet built with modelformset_factory and using a model with an optional ForeignKey, how can I make empty (null) associations to validate on that form? Here is a sample code: ### model class Prueba(models.Model): cliente = models.ForeignKey(Cliente, null = True) valor = models.CharField(max_length = 20) ### view def test(request): PruebaFormSet = modelformset_factory(model = Prueba, extra = 1) if request.method == 'GET': formset = PruebaFormSet() return render_to_response('tpls/test.html', {'formset' : formset}, context_instance = RequestContext(request)) else: formset = PruebaFormSet(request.POST) # dumb tests, just to know if validating if formset.is_valid(): return HttpResponse('0') else: return HttpResponse('1') In my template, i'm just calling the {{ form.cliente }} method which renders the combo field, however, I want to be able to choose an empty (labeled "------") value, as the FK is optional... but when the form gets submitted it doesn't validate. Is this normal behaviour? How can i make this field to skip required validation?

  • Javascript: Pass array as optional method args

    - by Dave Paroulek
    console.log takes a string and replaces tokens with values, for example: console.log("My name is %s, and I like %", 'Dave', 'Javascript') would print: My name is Dave, and I like Javascript I'd like to wrap this inside a method like so: function log(msg, values) { if(config.log == true){ console.log(msg, values); } } The 'values' arg might be a single value or several optional args. How can I accomplish this? If I call it like so: log("My name is %s, and I like %s", "Dave", "Javascript"); I get this (it doesn't recognize "Javascript" as a 3rd argument): My name is Dave, and I like %s If I call this: log("My name is %s, and I like %s", ["Dave", "Javascript"]); then it treats the second arg as an array (it doesn't expand to multiple args). What trick am I missing to get it to expand the optional args?

  • .Net SvcUtil: attributes must be optional

    - by Michel van Engelen
    Hi, I'm trying to generate C# code classes with SvcUtil.exe instead of Xsd.exe. The latter is giving me some problems. Command line: SvcUtil.exe myschema.xsd /dconly /ser:XmlSerializer Several SvcUtil problems are described and solved here: http://blog.shutupandcode.net/?p=761 One problem I can't solve is this one: Error: Type 'DatafieldDescription' in namespace '' cannot be imported. Attributes must be optional and from namespace 'http://schemas.microsoft.com/2003/10/Seri alization/'. Either change the schema so that the types can map to data contract types or use ImportXmlType or use a different serializer. ' I changed <xs:attribute name="Order" use="required"> to <xs:attribute name="Order" use="optional"> and <xs:attribute name="Order"> But the error remains. Is it possible to use attributes, or do I have to delete them all (in that case, this excercition is over)?

  • How do i configure optional flags in MVC 1.0 routes

    - by Thomas Jespersen
    I want to configure a route with optional flags. E.g. I want to be able to call the products page and send optional filters (flags) for offers and in stock options. If the flags are NOT specified then all products should be returned. http://localhost/products http://localhost/products/onlyOnOffer http://localhost/products/onlyInStock http://localhost/products/onlyInStock/onlyOnOffer [AcceptVerbs(HttpVerbs.Get)] public ActionResult GetProducts(bool onlyInStock, bool onlyOnOffer) { //... } How would I configure the route? Is it even possible in MVC 1.0? What about MVC 2.0.

  • velocity: join optional fields with a separator/prefix

    - by SlowStrider
    What would be the most concise/readable way in a velocity template to join multiple fields with a separator while leaving out empty or null Strings without adding excess separators? As an example we have a tooltip or appointments that goes like: Appointment ($number) [with $employee] [-] [$remarks] [-] [$roomToVisit] Where I used brackets to indicate optional data. When filled in it would normally show as Appointment (3) with John - ballroom - serve Java coffee When $remarks is empty but $roomToVisit is not, this becomes: Appointment (3) with John - ballroom When $remarks is "serve Java coffee" but $roomToVisit is empty we get: Appointment (3) with John - serve Java coffee When both are empty: Appointment (3) with John Bonus: also make the field prefix optional. When only $employee is empty we should get: Appointment (2) serve Java coffee - ballroom Ideally I would like the velocity template to look very similar to the first code box. If this is not possible, how would you achieve this with a minimum of distracting code tags? Similar ideas (first is much more verbose): Join with intelligent separators velocity: do something except in last loop iteration

  • Problem with optional arguments in C #defines

    - by imikedaman
    Hi, I'm having a problem with optional arguments in #define statements in C, or more specifically with gcc 4.2: bool func1(bool tmp) { return false; } void func2(bool tmp, bool tmp2) {} #define CALL(func, tmp, ...) func(tmp, ##__VA_ARGS__) int main() { // this compiles CALL(func2, CALL(func1, false), false); // this fails with: Implicit declaration of function 'CALL' CALL(func2, false, CALL(func1, false)); } That's obviously a contrived example, but does show the problem. Does anyone know how I can get the optional arguments to "resolve" correctly? Additional information: If I remove the ## before _VA_ARGS_, and do something like this: bool func2(bool tmp, bool tmp2) { return false; } #define CALL(func, tmp, ...) func(tmp, __VA_ARGS__) int main() { CALL(func2, false, CALL(func2, false, false)); } That compiles, but it no longer works with zero arguments since it would resolve to func(tmp, )

  • [Iphone-Dev] Assigning values : difference between properties and class variables ?

    - by gotye
    Hey guys, I noticed that I rarely use properties, due to the fact that I rarely need to access my object's variables outside my class ;) So I usually do : NSMutableArray *myArray; // not a property ! My question is : even if i don't declare myArray as a property, does iphone make a retain anyway if I do myArray = arrayPassedToMe; I think so but I just wanted to confirm ;) Any thoughts welcome !

  • How do I set Environment Variables in Visual Studio 2010?

    - by xarzu
    How do I set Environment Variables in Visual Studio 2010? I found this web page: http://msdn.microsoft.com/en-us/library/ee479070.aspx Which says: From the Project menu, choose Properties. In the left pane, select Configuration Properties, and then select Environment. But when I select "Configuration Properties", there is no "Enviroment" option: http://i67.photobucket.com/albums/h292/Athono/microsoft/newstuff.jpg This is an example in VS 2008: http://i21.photobucket.com/albums/b279/GrunchCan/env.jpg But how is it done in VS 2010?

  • Bash: how to process variables from an input file?

    - by gilgongo
    I've got a bash script that reads input from a file like this: while IFS="|" read -r a b do echo "$a something $b somethingelse" done < "$FILE" The file it reads looketh like this: http://someurl1.com|label1 http://someurl2.com|label2 However, I'd like to be able to insert the names of variables into that file when it suits me, and have the script process them when it sees them, so the file might look like this: http://someurl1.com?$VAR|label1 http://someurl2.com|label2 So $VAR could be, for example, today's date, producing an output like this: http://someurl1.com something label1 somethingelse http://someurl2.com?20100320 something label2 somethingelse

  • Passing variables from PHP to Javascript back to PHP using Ajax.

    - by ObjectiveJ
    I hope this makes sesne, please bare with me. So I have a PHP page that contains variables, I have some radial boxes, and on click of them, it calculates a price for the item you have clicked on. I do this by activating a js function that I have passed some variables to. Like so. PHP: <?php $result = mssql_query("SELECT * FROM Segments ORDER BY 'Squares'"); if (!$result) { echo 'query failed'; exit; } while ($row = mssql_fetch_array($result)) { ?> <span><?php echo $row["Squares"]; ?></span><input name="squares" type="radio" onclick="ajaxCases('<?php echo $row["Squares"]; ?>', '<?php echo $row["StartCaseID"]; ?>', '<?php echo $row["StartMatrixPrice"]; ?>')" value="<?php echo $row["Squares"]; ?>"<?php if ($row["Squares"] == "1") { ?> checked="checked" <?php }else{ ?> checked="" <?php } ?>/> <?php } ?> As you can see onclick it goes to a function called ajaxcases, this function looks like this. function ajaxCases(squares,start,price){ $('#step1').html('<p style="margin:100px 0px 0px 100px"><img src="images/ajax-loader-bigindic.gif" width="32" height="32" alt="" /></p>'); $('#step1').load("ajax-styles.php?squares="+squares); prevId1 = ""; document.varsForm.caseid.value=start; $('#step1price').html('<span style="margin:0px 0px 0px 30px"><img src="images/ajax-loader-price.gif" width="24" height="24" alt="" /></span>'); $('#step1price').load("ajax-step1-price.php?Squares="+Squares); return true; } This then goes to a php page called ajax-step1-price.php and I try to recall the variable Squares. However it doesn't work, I thought it was a GET however that returns undefined. In Summary: I would like to know how to pass a variable from PHP to JS then back to PHP, or if someone could just tell me where I am going wrong that would be greatly appreciated.

  • Where to store global variables like file paths in java ?

    - by Jules Olléon
    In my application I use some icons. Where should I store the path of the directory containing those icons ? The icons are used in different classes so it doesn't really make sense to store them in one of those classes in particular. I read that global variables are evil, but is it acceptable to use a class (eg Commons) containing only public static final fields to store this king of data ? What solution is used in professional applications ?
