Use JavaScript regex to replace numerical HTML entities with their actual characters

阅读更多关于 Use JavaScript regex to replace numerical HTML entities with their actual characters

问题 I'm trying to use JavaScript & regex to replace numerical HTML entities with their actual Unicode characters, e.g. foo's bar → foo's bar This is what I got so far: "foo's bar".replace(/&#([^\s]*);/g, "$1"); // "foo39s bar" All that's left to do is to replace the number with String.fromCharCode($1) , but I can't seem to get it to work. How can I do this? 回答1: "foo's bar".replace(/&#(\d+);/g, function(match, match2) {return String.fromCharCode(+match2);}) 回答2: "foo's bar".replace(/&#([^\s]*);/g

Sf2 : using a service inside an entity

阅读更多关于 Sf2 : using a service inside an entity

i know this has been asked over and over again, i read the topics, but it's always focused on specific cases and i generally try to understand why its not best practise to use a service inside an entity. Given a very simple service : Class Age { private $date1; private $date2; private $format; const ym = "%y years and %m month" const ... // some DateTime()->diff() methods, checking, formating the entry formats, returning different period formats for eg. } and a simple entity : Class People { private $firstname; private $lastname; private $birthday; } From a controller, i want to do : $som1 =

What is the difference between “LINQ to Entities”, “LINQ to SQL” and “LINQ to Dataset”

阅读更多关于 What is the difference between “LINQ to Entities”, “LINQ to SQL” and “LINQ to Dataset”

I've been working for quite a while now with LINQ. However, it remains a bit of a mystery what the real differences are between the mentioned flavours of LINQ. The successful answer will contain a short differentiation between them. What is the main goal of each flavor, what is the benefit, and is there a performance impact... P.S. I know that there are a lot of information sources out there, but I'm looking for a kind of a "cheat sheet" which instructs a newbie where to head for a specific goal. all of them are LINQ - Language Integrated Query - so they all share a lot of commonality.

Why do we need entity objects? [closed]

阅读更多关于 Why do we need entity objects? [closed]

I really need to see some honest, thoughtful debate on the merits of the currently accepted enterprise application design paradigm. I am not convinced that entity objects should exist. By entity objects I mean the typical things we tend to build for our applications, like "Person", "Account", "Order", etc. My current design philosophy is this: All database access must be accomplished via stored procedures. Whenever you need data, call a stored procedure and iterate over a SqlDataReader or the rows in a DataTable (Note: I have also built enterprise applications with Java EE, java folks please

How to make Nokogiri transparently return un/encoded Html entities untouched?

阅读更多关于 How to make Nokogiri transparently return un/encoded Html entities untouched?

How can I use Nokogiri with having html entities (like German umlauts) untouched? I.e.: # this is fine node = Nokogiri::HTML.fragment('ö') node.to_s # => 'ö' # this is not node = Nokogiri::HTML.fragment('ö') node.to_s # => 'ö' # this is what I need node = Nokogiri::HTML.fragment('ö') node.to_s # => 'ö' I've tried to mess with both PARSE_OPTIONS and :save_with options but could not come up with a way to have Nokogiri just transparently behave like above. Any pointers? svenfuchs Ok, my question has been answered by Aaron via twitter / gist : require

Programmatically loading Entity classes with JPA 2.0?

阅读更多关于 Programmatically loading Entity classes with JPA 2.0?

问题 With Hibernate you can load your Entity classes as: sessionFactory = new AnnotationConfiguration() .addPackage("test.animals") .addAnnotatedClass(Flight.class) .addAnnotatedClass(Sky.class) .addAnnotatedClass(Person.class) .addAnnotatedClass(Dog.class); Is there a way to do the same thing - programmatically loading your Entity classes - in a JPA 2.0 compliant way? The reason for this question is because I'd like to dynamically load my Entity classes, thus not necessarily programmatically. 回答1
