  • Javascript childNodes does not find all children of a div when appendchild has been used

    - by yesterdayze
    Alright, I am hoping someone can help me out. I apologize up front that this one may be confusing. I have included an example to try to help ease the confusion as this is better seen then heard. I have created a webpage that contains a group or set of groups. Each group has a subgroup. In a nutshell what is happening is this page will allow me to combine multiple groups containing subgroups into a new group. The page will give the chance to rename the old subgroups before they are combined into new groups in order to avoid confusion. When a group is renamed it will check to make sure there is not already a group with that name. If there is it will copy itself out of it's own group and into that group and then delete the original. If the group does not already exist it will create that group, copy itself in and then delete the original. Subgroups can also be renamed at which point they will move into the group with the same name if it exists, or create a new one if it doesn't. The page has a main div. The main div contains 'new sub group' divs. Inside each of those is another div containing the 'old sub group' divs. I use a loop through the child nodes of the 'new sub group' div when renaming a group in order to find each child node. These are then copied into a new div within the main div. The crux of the problem is this. If I loop through a DIV and copy all of the DIVs in it into a new or existing DIV all is well. When I then try to take that DIV and copy all of it's DIVs into another or new DIV it always skips one of the moved DIVs. For simplicity I have copied the entire working code below. To recreate the issue click the spot where the image should appear next to the name ewrewrwe and rename it to something else. All is well. Now click that new group the same way and name it something else. You will see it skip one each time. I have linked the page here: http://vtbikenight.com/test.html The link is clean, it is my personal website I use for a local motorycle group I am part of. Thanks for the help everyone!!! Please let me know if I can clarify on anything. I know the code is not the best right now, it is just demo code and my intent is to get the concept working then streamline it all.

  • grails gsp test evaluates to false, but block is still rendered. Why?

    - by ?????
    I'm baffled with Grails test operator. This expression: <g:if test="${!(preferences.displayOption.equals('ANA') || preferences.displayOption.equals('FLOP'))} "> ${!(preferences.displayOption.equals('ANA') || preferences.displayOption.equals('FLOP'))} </g:if> prints false How can that be? I'm printing the exact same condition I'm testing for! even though I'm certain the test condition evaluates to 'false' because it prints false in the very next line, the statements inside the g:if are being rendered. Anu ideas as to what's going on.

  • In Ruby are there any related applications of the syntax: class << self ... end

    - by pez_dispenser
    class << self attr_accessor :n, :totalX, :totalY end The syntax above is used for defining class instance variables. But when I think about what syntax implies, it doesn't make any sense to me, so I'm wondering if this type of syntax is used for any other types of definitions. My point of confusion here is this: class << self The append operator normally means "add what's on the right to the object on the left". But in the context of this block, how does that add up to "put the contents of this block into the definition of the class instance rather than the instance"? For the same reason I'm confused as to why in one context class << self can define class instance variables while in another it seems to create class variables such as here: class Point # Instance methods go here class << self # Class methods go here end end

  • Textbased issue-tracker/todo list for Git?

    - by anon
    I've been managing all of my todo-lists as ~/git-repo/todo which is kept under git. THen I add/delete files from the todo list, and have git autocommit all changes. However, I feel there should be more powerful tools. Besides "cil" and git-issues [neither of which I've tried], what tools are available? PS I want something that's entirely text/command line based. Thanks!

  • Django : presenting a form very different from the model and with multiple field values in a Django-

    - by sebpiq
    Hi ! I'm currently doing a firewall management application for Django, here's the (simplified) model : class Port(models.Model): number = models.PositiveIntegerField(primary_key=True) application = models.CharField(max_length=16, blank=True) class Rule(models.Model): port = models.ForeignKey(Port) ip_source = models.IPAddressField() ip_mask = models.IntegerField(validators=[MaxValueValidator(32)]) machine = models.ForeignKey("vmm.machine") What I would like to do, however, is to display to the user a form for entering rules, but with a very different organization than the model : Port 80 O Not open O Everywhere O Specific addresses : --------- delete field --------- delete field + add address field Port 443 ... etc Where Not open means that there is no rule for the given port, Everywhere means that there is only ONE rule (0.0.0.0/0) for the given port, and with specific addresses, you can add as many addresses as you want (I did this with JQuery), which will make as many rules. Now I did a version completely "handmade", meaning that I create the forms entirely in my templates, set input names with a prefix, and parse all the POSTed stuff in my view (which is quite painful, and means that there's no point in using a web framework). I also have a class which aggregates the rules together to easily pre-fill the forms with the informations "not open, everywhere, ...". I'm passing a list of those to the template, therefore it acts as an interface between my model and my "handmade" form : class MachinePort(object): def __init__(self, machine, port): self.machine = machine self.port = port @property def fully_open(self): for rule in self.port.rule_set.filter(machine=self.machine): if ipaddr.IPv4Network("%s/%s" % (rule.ip_source, rule.ip_mask)) == ipaddr.IPv4Network("0.0.0.0/0"): return True else : return False @property def partly_open(self): return bool(self.port.rule_set.filter(machine=self.machine)) and not self.fully_open @property def not_open(self): return not self.partly_open and not self.fully_open But all this is rather ugly ! Do anyone of you know if there is a classy way to do this ? In particular with the form... I don't know how to have a form that can have an undefined number of fields, neither how to transform these fields into Rule objects (because all the rule fields would have to be gathered from the form), neither how to save multiple objects... Well I could try to hack into the Form class, but seems like too much work for such a special case. Is there any nice feature I'm missing ?

How do I replace this "minus" icon with a "delete" which will totally delete the appropriate div when clicked?

  • C question: Padding bits in unsigned integers and bitwise operations (C89)

    - by Anonymous Question Guy
    I have a lot of code that performs bitwise operations on unsigned integers. I wrote my code with the assumption that those operations were on integers of fixed width without any padding bits. For example an array of 32 bit unsigned integers of which all 32 bits available for each integer. I'm looking to make my code more portable and I'm focused on making sure I'm C89 compliant (in this case). One of the issues that I've come across is possible padded integers. Take this extreme example, taken from the GMP manual: However on Cray vector systems it may be noted that short and int are always stored in 8 bytes (and with sizeof indicating that) but use only 32 or 46 bits. The nails feature can account for this, by passing for instance 8*sizeof(int)-INT_BIT. I've also read about this type of padding in other places. I actually read of a post on SO last night (forgive me, I don't have the link and I'm going to cite something similar from memory) where if you have, say, a double with 60 usable bits the other 4 could be used for padding and those padding bits could serve some internal purpose so they cannot be modified. So let's say for example my code is compiled on a platform where an unsigned int type is sized at 4 bytes, each byte being 8 bits, however the most significant 2 bits are padding bits. Would UINT_MAX in that case be 0x3FFFFFFF (1073741823) ? #include <stdio.h> #include <stdlib.h> /* padding bits represented by underscores */ int main( int argc, char **argv ) { unsigned int a = 0x2AAAAAAA; /* __101010101010101010101010101010 */ unsigned int b = 0x15555555; /* __010101010101010101010101010101 */ unsigned int c = a ^ b; /* ?? __111111111111111111111111111111 */ unsigned int d = c << 5; /* ?? __111111111111111111111111100000 */ unsigned int e = d >> 5; /* ?? __000001111111111111111111111111 */ printf( "a: %X\nb: %X\nc: %X\nd: %X\ne: %X\n", a, b, c, d, e ); return 0; } is it safe to XOR two integers with padding bits? wouldn't I XOR whatever the padding bits are? I can't find this behavior covered in C89. furthermore is the c var guaranteed to be 0x3FFFFFFF or if for example the two padding bits were both on in a or b would c be 0xFFFFFFFF ? same question with d and e. am i manipulating the padding bits by shifting? I would expect to see this below, assuming 32 bits with the 2 most significant bits used for padding, but I want to know if something like this is guaranteed: a: 2AAAAAAA b: 15555555 c: 3FFFFFFF d: 3FFFFFE0 e: 01FFFFFF Also are padding bits always the most significant bits or could they be the least significant bits? Thanks guys EDIT 12/19/2010 5PM EST: Christoph has answered my question. Thanks! I had also asked (above) whether padding bits are always the most significant bits. This is cited in the rationale for the C99 standard, and the answer is no. I am playing it safe and assuming the same for C89. Here is specifically what the C99 rationale says for §6.2.6.2 (Representation of Integer Types): Padding bits are user-accessible in an unsigned integer type. For example, suppose a machine uses a pair of 16-bit shorts (each with its own sign bit) to make up a 32-bit int and the sign bit of the lower short is ignored when used in this 32-bit int. Then, as a 32-bit signed int, there is a padding bit (in the middle of the 32 bits) that is ignored in determining the value of the 32-bit signed int. But, if this 32-bit item is treated as a 32-bit unsigned int, then that padding bit is visible to the user’s program. The C committee was told that there is a machine that works this way, and that is one reason that padding bits were added to C99. Footnotes 44 and 45 mention that parity bits might be padding bits. The committee does not know of any machines with user-accessible parity bits within an integer. Therefore, the committee is not aware of any machines that treat parity bits as padding bits. EDIT 12/28/2010 3PM EST: I found an interesting discussion on comp.lang.c from a few months ago. Bitwise Operator Effects on Padding Bits (VelocityReviews reader) Bitwise Operator Effects on Padding Bits (Google Groups alternate link) One point made by Dietmar which I found interesting: Let's note that padding bits are not necessary for the existence of trap representations; combinations of value bits which do not represent a value of the object type would also do.

  • Trigger Code on a table in my ERP Database

    My ERP Vendor has the following trigger on a table: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TRIGGER [dbo].[SOItem_DeleteCheck] ON [dbo].[soitem] FOR DELETE AS BEGIN DECLARE @RecCnt int, @LogInfo varchar(256) SET @RecCnt = (SELECT COUNT(*) FROM deleted) IF @RecCnt > 150 BEGIN RAISERROR (54010, 18, 1, 'SOItem') WITH LOG ROLLBACK TRANSACTION END SET @LogInfo = 'Deleting ' + LTRIM(STR(@RecCnt)) + ' Rows From SOItem' EXEC LogDeletes @LogInfo END GO This seems very inefficient to me. Doesn't select count(*) take longer than Count(specific field)?

  • Error in creating template class

    - by Luciano
    I found this vector template class implementation, but it doesn't compile on XCode. Header file: // File: myvector.h #ifndef _myvector_h #define _myvector_h template <typename ElemType> class MyVector { public: MyVector(); ~MyVector(); int size(); void add(ElemType s); ElemType getAt(int index); private: ElemType *arr; int numUsed, numAllocated; void doubleCapacity(); }; #include "myvector.cpp" #endif Implementation file: // File: myvector.cpp #include <iostream> #include "myvector.h" template <typename ElemType> MyVector<ElemType>::MyVector() { arr = new ElemType[2]; numAllocated = 2; numUsed = 0; } template <typename ElemType> MyVector<ElemType>::~MyVector() { delete[] arr; } template <typename ElemType> int MyVector<ElemType>::size() { return numUsed; } template <typename ElemType> ElemType MyVector<ElemType>::getAt(int index) { if (index < 0 || index >= size()) { std::cerr << "Out of Bounds"; abort(); } return arr[index]; } template <typename ElemType> void MyVector<ElemType>::add(ElemType s) { if (numUsed == numAllocated) doubleCapacity(); arr[numUsed++] = s; } template <typename ElemType> void MyVector<ElemType>::doubleCapacity() { ElemType *bigger = new ElemType[numAllocated*2]; for (int i = 0; i < numUsed; i++) bigger[i] = arr[i]; delete[] arr; arr = bigger; numAllocated*= 2; } If I try to compile as is, I get the following error: "Redefinition of 'MyVector::MyVector()'" The same error is displayed for every member function (.cpp file). In order to fix this, I removed the '#include "myvector.h"' on the .cpp file, but now I get a new error: "Expected constructor, destructor, or type conversion before '<' token". A similar error is displayed for every member as well. Interestingly enough, if I move all the .cpp code to the header file, it compiles fine. Does that mean I can't implement template classes in separate files?

  • Compare two String with MySQL

    - by Scorpi0
    Hi, I wan't to compare two strings in a SQL request so I can retrieve the best match, the aim is to propose to an operator the best zip code possible. For example, in France, we have Integer Zip code, so I made an easy request : SELECT * FROM myTable ORDER BY abs(zip_code - 75000) This request returns first the data closest of Paris. Unfortunatelly, United Kingdom have zip code like AB421RS, so my request can't do it. I see in SQL Server a function 'Difference' : http://www.java2s.com/Code/SQLServer/String-Functions/DIFFERENCEworkoutwhenonestringsoundssimilartoanotherstring.htm But I use MySQL.. Is there anyone who have a good idea to do the trick in one simple request ? PS : the Levenshtein Distance will not do it, as I really wan't to compare string like if they were number. ABCDEF have to be closer to AWXYZ than to ZBCDEF.

  • How to use an RPM option in a yum upgrade?

    I need to upgrade an RPM installed via YUM, which has an fatal bug in its postun section. This will get run (and delete the program's user, which is what I want to not happen) when I run "yum upgrade". I know that if I were using rpm directly, I could just use the "-nopostun" option to skip this section, but I don't see a way of accessing that option from yum's man page. Anyone know a way round this?
