  • jQuery ajax return value

    - by Jordan Pagaduan
    How can I return the value "pinNumber" from jquery ajax so I can append it outside of the ajax. Here is my code var x = pinLast + 1; for(i=x;i<=pinMany;i++) { var i = x++; var cardNumber = i.toPrecision(8).split('.').reverse().join(''); var pinNumber = ''; jQuery.ajax({ type: "POST", url: "data.php", data: "request_type=generator", async: false, success: function(msg){ var pinNumber = msg; return pinNumber; //pin number should return } }); jQuery('.pin_generated_table').append(cardNumber+' = '+pinNumber+''); // the variable pinNumber should be able to go here } Please ask me if you don't understand.. ^^ thanks

  • Validate decimal number in (known) national format

    - by Álvaro G. Vicario
    PHP has many built-in functions to validate numbers but they all expect input in computer format: 1234.56. I need to validate stuff like 1,234.56 (English) or 1.234,56 (Spanish), together with some typical attributes (accepted range, max number of decimals, etc.). I started writing my own function but I soon got lost. It's easy to read the user input into a float variable but I want to be able to detect numbers with invalid formats like 1,23456.7 or 1..25. Do you have any recommendation on the subject? (Decimal and thousand characters are known beforehand and it's okay to hard-code digit groups as three, there's no need to cover Indian number format.)

  • SQL Server 2008 Stored Procedure

    - by user238319
    I cannot store the date data type variables using stored procedure. My code is: ALTER PROCEDURE [dbo].[Access1Register] -- Add the parameters for the stored procedure here @MobileNumber int, @CitizenName varchar(50), @Dob char(8), @VerificationCode int AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here select CAST(@dob As DATE) Insert Into Access1 (MobileNo,CitizenName,Dob,VerificationCode) values(@MobileNumber,@CitizenName,@Dob,@VerificationCode) go If I exec this procedure it is executing, but there is an error occured in the date type variable. It's raising the error as invalid item '-'.

  • Question regrarding declaring a property

    - by Simon
    Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?

  • Identifying the view selected in a ContextMenu (Android)

    - by Casebash
    In Android, onContextItemSelected has a single MenuItem argument and so it isn't clear how to identify the view selected. MenuItem.getMenuInfo provides access to Contextmenu.ContextMenuInfo, but while both known subclasses provide access to the target view, there does not appear to be an accessor on the interface. One alternative is to save the View provided in onCreateContextMenu in a private class variable which relies on onCreateContextMenu not being called again in the activity before onContextItemSelected. Another is to use the id of the View for the itemId argument of ContextMenu.add. If we do this, we would then need to identify the option selected from the context menu by using its (possibly internationalised) title. What is the best method for identifying the View selected in onContextSelected?

  • Java Null Pointer Exception :-(

    - by John-Michael Reed
    I've got a Null Pointer Exception in my main that just won't go away and I'm totally out of ideas. The error is on the line "Board[x][y].color = 2;" in which Board is a public, static array of piece objects that contain instance variables like the one "color" that is being set to 2 in the above statement. Pieces is not static - that is there are many different copies of pieces, each with its own data, but only one board. The array has been initialized and defined as both public Piece[][] Board = new Piece[8][8] and public static Piece[][] Board = new Piece[8][8], but no matter how I mess around with it (getting rid of static, putting the variable in another object, etc.), I can't seem to get the error to go away. Help?

  • Prevent Erroneous Property Assignment

    - by Gordon
    Porting android applications to iphone applications always gives me the following pattern that I accidentally create: - (void) myFunc:(id)prop { self.property = property; } Which instead should be: - (void) myFunc:(id)prop { self.property = prop; } This always causes my program to quietly break because property gets reset to its existing value rather than being set to the new value, 'prop'. I cannot name the parameter 'prop' to 'property' since the compile complains that the parameter masks the instance variables visibility. Is there a good way to avoid this situation? There are no compiler warnings. Is there a way to make xcode prevent this? I cannot see very many situations where you would set a property to the value of its underlying instance variable (maybe to trigger a KVO binding?), but I don't see myself doing that in majority of cases. I understand the above code is synthetic and should be done with @synthesize, but I am just using it as a simplified example to illustrate my point.

  • Escaping if/else in Jade template

    - by Collin Estes
    So I have a simply block of html in my jade template with a loop: each dude, i in dudes div(class='someClass') div.otherStuff span.someContent #{name} I want to apply a data attribute to my top most div when a certain looping condition is met, in this case the first dude, I set it up like this each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') else div(class='someClass') div.otherstuff span.someContent Setup like this it causes the div.otherStuff div and the span.someContent to only display on the else condition. I've moved the tab spaces around on those items but I can't get it escape that else and give the div.otherStuff and span.someContent to both the first dude and the subsequent dudes after that. I've also tried setting that data attr to a variable and trying to apply it that way but without any success. What I end up doing to get around it is this: each dude, i in dudes if i == 0 div(class='someClass, data-someAttr='first dude') div.otherstuff span.someContent else div(class='someClass') div.otherstuff span.someContent How do I escape that if/else so I dont have to duplicate the div.otherStuff and span.someContent?

  • Instantiating class by string using PHP 5.3 namespaces

    - by Kevin
    I can't get around an issue instantiating a new class by using a string variable and PHP 5.3. namespaces. For example, this works; $class = 'Reflection'; $object = new $class(); However, this does not; $class = '\Application\Log\MyClass'; $object = new $class(); A fatal error gets thrown stating the class cannot be found. However it obviously can be instantiated if using the FQN i.e.; $object = new \Application\Log\MyClass; I've found this to be aparrent on PHP 5.3.2-1 but not not in later versions. Is there a work around for this?

  • Barcode field length

    - by bestattendance
    I'm writing some attendance software. Each member will have an ID card with a barcode which they will use to sign in to events. How long should the barcode field be in my database? I'd like to accept Code 39 and Code 128 barcodes. I know these are variable length codes, so what should I set the max length to? Thanks! EDIT: My clients will be using a variety of third-party barcode printing tools.

  • Ruby on Rails - Calendar Display

    - by user335725
    We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

  • Setting precision on std::cout in entire file scope - C++ iomanip

    - by Ivan
    Hi all, I'm doing some calculations, and the results are being save in a file. I have to output very precise results, near the precision of the double variable, and I'm using the iomanip setprecision(int) for that. The problem is that I have to put the setprecision everywhere in the output, like that: func1() { cout<<setprecision(12)<<value; cout<<setprecision(10)<<value2; } func2() { cout<<setprecision(17)<<value4; cout<<setprecision(3)<<value42; } And that is very cumbersome. Is there a way to set more generally the cout fixed modifier? Thanks

  • Symfony: Pass an object from another module to a form

    - by djcloud23
    I have a symfony project and I have one model, which for this example I will name Boat. From the Boat's showSuccess page, I would like to make a link to another model's form page. For this example we will call it Ticket. When they click on the link, I would like for the Boat object to be passed to the Ticket form because I have to display some of that specific Boat's fields (title, price, etc) on the Ticket form page (newSuccess.php). I guess my question is, how do I pass an object (as a variable) to another model's "new" form page. I have looked everywhere and I can't seem to find an answer that works for me. Thank you!

  • Selecting an option with javascript

    - by Fibericon
    I have a drop down menu that I want to have selected on page load. This is what I'm using at the moment: var selector = document.getElementById("action_person").firstChild; var n = 0; while(selector.options[n] != null) { if(selector.options[n].value == "person") { selector.options.selectedIndex = n; } n++; } I've also tried replacing selector.options.selectedIndex = n with selector.options[n].selected = true. However, it never selects for me. It always shows the item at the top of the drop down. I've verified that the value "person" does exist in the drop down, and that the variable "selector" does point to a valid drop down. What am I doing wrong here?

  • HttpSessionState Where, How, Advantages?

    - by blgnklc
    You see the code below, how I did use the session variable; So the three questions are; 1- Where are they stored? (Server or Client side) 2- Are they unique for each web page visitor? 3- Can I remove it using ajax or simple js code when my job is done with it? or it will be removed automatically..? sbyte[][] arrImages = svc.getImagesForFields(new String[] { "CustomerName", "CustomerSurName" }); Dictionary<string, byte[]> smartImageData = new Dictionary<string, byte[]>(); int i = 0; foreach (sbyte[] bytes in arrImages) { smartImageData.Add(fieldNames[i], ConvertToByte(bytes)); i++; } Session.Add("SmartImageData", smartImageData);

  • How to increment a value using a C-Preprocessor?

    - by mystify
    Example: I try to do this: static NSInteger stepNum = 1; #define METHODNAME(i) -(void)step##i #define STEP METHODNAME(stepNum++) @implementation Test STEP { // do stuff... [self nextFrame:@selector(step2) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step3) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step4) afterDelay:1]; } // ... When building, Xcode complains that it can't increment stepNum. This seems logical to me, because at this time the code is not "alive" and this pre-processing substitution stuff happens before actually compiling the source code. Is there another way I could have an variable be incremented on every usage of STEP macro, the easy way?

  • c# passing something from child form to parent

    - by Alan Bennett
    hi guys. so i have this form and on it is a combo box populated from a database via a SQL method. and i have another form which allows us to maintain the database table etc. so i make a new instance of the second form doing: Form1 frm = new Form2; frm.show(); once i have done what ever i wanted to do on the second form and i close it, i need to somehow trigger an event or something which will refresh the combo box and the code behind it. i was thinking of some onchange or focus event for the whole form, the problem is i have 5 of these combo boxes and running all the SQL again. i also thought of passing somesort of variable thro but then i would still need an event for that. any ideals would be awesome

  • JQuery post to php

    - by RussP
    Why is it that I can never get JQuery serialize to work properly. I guess I must be missing something. I can serialize a form data and it shows in an alert: var forminfo = $j('#frmuserinfo').serialize(); alert(forminfo); I then post to my PHP page thus: $j.ajax({ type: "POST", url: "cv-user-process.php", data: "forminfo="+forminfo, cache: false, complete: function(data) { } }); But WHENEVER (not the first time) I try to insert/update the data in the DB I only ever get 1 varaible passed: Here is my PHP script: $testit = mysql_query("UPDATE cv_usersmeta SET inputtest='".$_POST['forminfo']."' WHERE user='X'"); the data passed only ever gets the first variable. why? I think it is more the way I deal with the php but it drives me nuts and always takes me far too long to find where I am going wrong.

  • How to assign the value of document.cookie to your browser cookies?

    - by Ricket
    I'm a developer (and therefore a tester) of a website. Our site accepts any JavaScript or HTML from an user but I haven't been successful in explaining the danger of it, as obvious as it is. So I would like to prove it by logging in as my boss to prove to him that there is definitely a real danger here. I think this will put down any of his arguments and let us move onto filtering content like this. (note this question is not about filtering, or other suggestions on JavaScript tricks) I already know how to steal the value of the document.cookie variable with AJAX and a PHP file, but once you have that string of name=value;name=value;..., how do you apply it to your own browser? This is programming related because I am asking about tools which will help me debug my web program.

  • C - memset segfault for statically allocated char array

    - by user1327031
    I get a segfault when trying to memset an array of chars that was allocated statically, but not for an array of the same length that was allocated using malloc. variable definitions: //static char inBuff[IN_BUFF_LEN]; //dynamic char * inBuffD; function call: //static, cast used because char** != char (*) [n] serverInit(portNum, (char**) &inBuff, &serv_addr, &sockfd) //dynamic serverInit(portNum, &inBuffD, &serv_addr, &sockfd) use within the function: memset(*inBuffAdr, 0, IN_BUFF_LEN); I suspect that my problem is in the difference of the function calls, or to be more precise, my incomplete understanding of the "char** != char (*) [n]" situation. But I have been banging at this for too long and can't see the forest from the trees so any hints and advice would be very appreciated.

  • How to add characters to reach the maximum size of a char[].

    - by Bon_chan
    Hi folks, I have the following part of code : for(int i=0;i<n;i++) { printf("Student %d\n",i+1); printf("Enter name : "); scanf("%s",&(student+i)->name); fflush(stdin); lengthName = strlen((student+i)->name); while(lengthName !='\0') { }} when the length is shorter than 10, it will add hyphens until reaching the maximum size. Ex : John = 6 hyphens will be added I know how to do it in csharp but can't figure it out in c. Could some of you give me some lights please? PS : Oh yes the variable name is char name[10+1] and it a part of the structure called student.

  • How do I send the ckeditor config using jQuery service?

However, I get an error thrown in my console!: v is undefined [Break On This Error] var u=n.toolbox.toolbars,v=n.config.to...aximize','ShowBlocks','-','About']]; If I comment out the config: //CKEDITOR.config.toolbar = config; everything works fine but the configuration doesn't exist, of course...

  • What is __path__ useful for?

    - by Jason Baker
    I had never noticed the __path__ attribute that gets defined on some of my packages before today. According to the documentation: Packages support one more special attribute, __path__. This is initialized to be a list containing the name of the directory holding the package’s __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package. While this feature is not often needed, it can be used to extend the set of modules found in a package. Could somebody explain to me what exactly this means and why I would ever want to use it?
