Hello there,
I'm working with a page that has several links that contain the same href text, and I need to select the second anchor element on the page that contains said href text. Here's a simplified version of the link structure of the page:
<a href="same/link/to/stuff/">same link</a>
<a href="same/link/to/stuff/">same link</a>
How do I fashion my selector so that it only selects the second anchor in the above example?
Thanks!!
I'm making a new php page and I get the error
Fatal error: Call to undefined function phpinclude_once() in /home8/nuventio/public_html/marketing/pb2/dashboard.php on line 1
I'm not sure why I'm getting this error, I've done previous pages the same way as this with no problems. This is the line in question:
<?php
include_once("../utils.php");
?>
After that it just goes into regular HTML code. It works fine without that line.
I am aware of array_walk() and array_map(). However when using the former like so (on an old project) it failed
array_walk($_POST, 'mysql_real_escape_string');
Warning: mysql_real_escape_string()
expects parameter 2 to be resource,
string given.
So I went with this slightly more ugly version
foreach($_POST as $key => $value) {
$_POST[$key] = mysql_real_escape_string($value);
}
So why didn't the first way work? What is the best way to map values of an array to a function?
Why does x alerts undefined for iframe but works for embed. I'm grabbing the iframe or embed code from a textarea
<iframe src="http://www.youtube.com/embed/9kiWvkj2ldWiU?hd=1"></iframe>
var textarea = $('#embedModal textarea'),
textareaValue = textarea.val(),
$embed = $($(textareaValue).find('iframe')),
x = $embed.attr('src');
alert(x); //alerts undefined for iframe
If you change find('iframe') to find('embed') and you try with the below embed code. then i'm able to get the value of src, but with iframe i get undefined. Seems strange.
<embed src="http://www.youtube.com/embed/9kiWvkj2ldWiU?hd=1"></embed>
Hi guys,
Is it possible to assign multiple provisions to an iDevice? To be honest, I'm not sure if I'm using the correct terminology, but basically, I'm developing an iPad app for a company and I've only been testing it in the simulator because I don't have a registration to the developer program and they haven't setup their enterprise registration yet either. And I'm sure you all know how limited the simulator is...
I don't really care about the $99 it costs to join, but what I'm worried about is having my iDevices locked permanently to my personal registration and unable to switch back and forth to the enterprise registration.
I'd appreciate it if someone can explain to me how the registrations work. And keep in mind, I'm a dummy. :)
Thanks in advance!
Hello everyone.
The Cocoa framework has a convention to always call self = [super init] in the init method of an inherited class, because [super init] may return a new instance.
What will happen if I do this?
@interface MyClass : NSObject /* or any other class */ {
int ivar_;
}
@end
@implementation MyClass
- (id)init {
ivar_ = 12345;
if ((self = [super init])) {
NSLog(@"ivar_'s value is %d", ivar_);
}
return self;
}
@end
In the case when [super init] returns a new instance, what will I see in the console? ivar_'s value is 0?
I can't think of a way to check this myself, because I don't know which class may return a new instance from its init method. Also, can't seem to find explicit clarification for this scenario in the docs.
Could anyone help me out? Thanks!
I have a simple MySQL table thats contains a list of categories, level is determined by parent_id:
id name parent_id
---------------------------
1 Home 0
2 About 1
3 Contact 1
4 Legal 2
5 Privacy 4
6 Products 1
7 Support 1
I'm attempting to make a breadcrumb trail. So i have the 'id' of the child, I want to get all available parents (iterating up the chain until we reach 0 "Home"). There could be any number or child rows going to an unlimited depth.
Currently I am using an SQL call for each parent, this is messy. Is there a way in SQL to do this all on one query?
I am getting "ASCII encoding" errors when I insert into my database because I did a fresh install of the MYSQL.
I'd like to change the default to UTF-8 again.
Hi,
I'm looking at Silverlight architectures and RIA Services looks interesting, but I am a bit concerned about its prelease status and how the feature set will change.
We need our client app to be as responsive as possible over a slow network link, so a high priority is a solid sync system for pushing model state changes from the client back to the server. Will RIA Services help us in this regard or will I have to roll my own logic to do this ? Are there any other frameworks that can assist with this? Is the feature set involved in these requirements liable to change much in the next couple of months?
If it makes any difference, our frontend is 100% Silverlight, so we dont need to worry about exposing SOAP APIs from the server or anything like that. It appears to me that RIA so far is a bit more mature for Silverlight use. Is this correct?
Hi:
My program uses sockets for inter-process communication. There is one server listening on a socket port(B) on localhost waiting for a list of TCP clients to connect. And on the other end of the server is another a socket(A) that sends out data to internet. The server is designed to take everything the TCP clients send him and forward to a server on the internet. My question is if two of the TCP clients happened to send data at the same time, is this going to be a problem for the server's outgoing socket(A)?
Thanks
let's say I have a list
li = [{'q':'apple','code':'2B'},
{'q':'orange','code':'2A'},
{'q':'plum','code':'2A'}]
What is the most efficient way to return the count of unique "codes" in this list?
In this case, the unique codes is 2, because only 2B and 2A are unique.
I could put everything in a list and compare, but is this really efficient?
All my previous projects have had this workflow on Contact pages
User submits form
Controller gets $_POST details
Controller validates details (and sets error messages if necessary)
Controller sends email
Controller redirects to thanks page
Is this the standard workflow?
I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?
We use JUnit 3 at work and there is no ExpectedException annotation. I wanted to add a utility to our code to wrap this:
try {
someCode();
fail("some error message");
} catch (SomeSpecificExceptionType ex) {
}
So I tried this:
public static class ExpectedExceptionUtility {
public static <T extends Exception> void checkForExpectedException(String message, ExpectedExceptionBlock<T> block) {
try {
block.exceptionThrowingCode();
fail(message);
} catch (T ex) {
}
}
}
However, Java cannot use generic exception types in a catch block, I think.
How can I do something like this, working around the Java limitation?
Is there a way to check that the ex variable is of type T?
I'm implementing a checking system in C++. It runs executables with different tests. If the solution is not correct, it can take forever for it to finish with certain hard tests. That's why I want to limit the execution time to 5 seconds.
I'm using system() function to run executables:
system("./solution");
.NET has a great WaitForExit() method, what about native C++?. I'm also using Qt, so Qt-based solutions are welcome.
So is there a way to limit external process' execution time to 5 seconds?
Thanks
After adding items, attempting to view my cart leads me to this error:
nil can't be coerced into Float
with the math line in this method in my line_item model highlighted:
def total_price
product.price * quantity
end
line items create action
def create
product = Product.find(params[:product_id])
@line_item = @cart.add_product(product.id)
@line_item.quantity = params[:quantity]
view
<div id= "text_field"><%= text_field_tag 'quantity' %> </div>
<%= button_to 'Add to Cart', line_items_path(:product_id => product) %>
This has held me back for a couple days. (I'm new). Thanks.
Some mac apps, like iTunes and Spotify, react to the play/pause/next/previous buttons on some Apple keyboards.
Presumably they're tapping into some sort of NSNotification, how can I do the same?
I am writing an abstract superclass where literally every method is going to be overridden. There is some default functionality I could implement, but most of the time it's enough to leave the implementation to the subclass writer.
Since just about every method is going to be overwritten, how much should I make virtual and how much should I just leave as regular methods? In the current incarnation, everything is virtual, but I still haven't let this loose to anyone to use, so the design is flexible.
What advantages/disadvantages are there to virtual functions? Links to good reading material about this would be appreciated.
I have a class User and a class History. History has 'User' property, and User has 'Histories' property. So there's a database relationship.
But when I create a new User history class and set UserID property, I can't access the 'User' property.
var history = new History { UserID = 1 };
// history.User = null ???
How can I get the user?
I know that HTML is viewed on the client side and PHP is on the server side. I guess I want to know why they use different things. Why doesn't the client just view a php file?
#include <iostream>
using namespace std;
int main() {
short int enterVal;
cout << "enter a number to say: " << endl;
cin >> enterVal;
system("say "%d"") << enterVal;
return 0;
}
Is what I am currently trying. I want the user to enter a number and the system() function says it basically. The code above has an error which says " 'd' was not declared in this scope ". Thanks in advance.
