argument-passing

问题 What are [function] arguments? What are they used for? I started learning Python very recently; I'm new to programming and I apologize for this basic question. In every Python tutorial I go through they talk about arguments . I have looked for the answer to this question and have found many answers but they are just a little too hard for me to understatnd. I may just be missing some conceptual background. So... when I define a function, what are the things in parenthesis used for? Example:

问题 Im building a contact form for my wordpress theme. I want the ability to enter a receiver adress from the backend. At the moment I am passing the variable with a hidden input field. <input type="text" class="hidden" name="receiver" value="<?php get_option('admin_email') ?>"/> I read that I shouln't do this, because its insecure. But how would I do it then? Edit: Here is my process.php. I tried to get the admin email but that breaks it somehow. <?php if( isset($_POST) ){ //form validation vars

问题 I am making an iPhone app which needs to send a couple of arrays to a php script and then the php script needs to take the value(s) of those arrays and write an xml file. I know how to write the xml file with php, but I am unsure how to send the data to the php script from the iOS app... Is it even possible to send a php script a couple of integer arguments from iOS? Sorry I am very new to php and iOS (programming in general for that matter). Thanks 回答1: make GET or POST request from iOS app

问题 I wrote the following Perl Class: package Menu; use strict; my @MENU_ITEMS; my $HEADER = "Pick one of the options below\n"; my $INPUT_REQUEST = "Type your selection: "; sub new { my $self = {}; $self->{ITEM} = undef; $self->{HEADER} = undef; $self->{INPUT_REQUEST} = undef; bless($self); return $self; } sub setHeader { my $self = shift; if(@_) { $self->{HEADER} = shift } $HEADER = $self->{HEADER}."\n"; } sub setInputRequest { my $self = shift; if(@_) { $self->{INPUT_REQUEST} = shift } $INPUT

问题 in code behind : string func = "showSuccessMessage("+name+");"; ClientScript.RegisterStartupScript(this.GetType(), "success", func, true); in a js file : function showSuccessMessage(user) { $("#box").dialog({ title:"User Registration", html: user.toString() + " Successfully Registered", modal: true, buttons: { Ok: function () { $(this).dialog("close"); var s = "../Pages/main.aspx"; window.location = s; } } }); } // end function when i try to pass the func string with no arguments every thing

问题 I'm writing a batch file for automating the creation of typical folder structures for products that we sell. I would like to be able to call my batch file with 2 optional arguments; the name of the supplier and a file for creating lots of folders at once. If no supplier is supplied the script asks via standard input who the supplier is. If no file is supplied the script asks for the name of the folder you wish to create. If a file is passed as an argument I would like the script to read the

问题 So, I would like to be able to call functions from a c++ dll. For certain reasons, I would like to call them from an __asm block in my C++ code. My question is this: I know that before I call the function, I have to push its arguments on the stack in the order specified by the function's calling convention.However, can i simply do something like this: int a=5; double b = 5.0; __asm{ push b push a call functionAddress } What worries me is the fact that I seem to remember that the standard word

问题 Can you call a servlet with a link? For example <a href="/servletName">link text</a> And possibly pass parameters to the request object by adding them to the querystring. If not, I have seen this kind of thing: RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(/MyServlet); dispatcher.include(request,response); But how would I trigger this? For example if it was JavaScript code I could put it within a jQuery click function, or if this was a servlet I would put it into a

问题 I have a while loop that reads in a single file: my %MyItems = (); while (my $line = <>) { chomp $line; if ($line =~ m/(.* $mon $day) \d{2}:\d{2}:\d{2} $year: ([^:]+):backup:/) { my $BckupDate="$1 $year"; my $BckupSet =$2; $MyItems{$BckupSet}->{'MyLogdate'} = $BckupDate; $MyItems{$BckupSet}->{'MyDataset'} = $BckupSet; if ($line =~ m/(ERROR|backup-size|backup-time|backup-status)[:=](.+)/) { my $BckupKey=$1; my $BckupVal=$2; $MyItems{$BckupSet}->{$BckupKey} = $BckupVal; } } } The script is

问题 I am attempting to build a python wrap for some fortran code I have using f2py and am experiencing a very odd problem. I am using Python 3.4.3 32 bit, gfortran 4.8.1, and numpy 1.9.2 on Windows 8. f2py compiles the fortran code so I can call it from python. The code has multiple subroutines. Some of them work, but two do not. The important difference seems to be subroutine declaration spanning multiple lines. The working subroutines are declared on a single line. The ones that fail span
