问题 I'm trying to show a component when first load the page with lazy loading that only load the content if it's in the view. For example: - There are 10 components on the page and I want to show/scroll to the component number 7 on first load with lazy loading(for performance). How do I do this correctly? Challenge here is because these components are lazy loading and have huge images that messed up the scrollIntoView() and scrolled too much to the top passed the component. I've tried these

问题 I implement a Chrome extension. The extension needs to get all images URLs of webpages. However, some webpages have "lazy load" plug-in. My question is if it is possible that I can still get URLs without required manually scrolling down? 回答1: Many of the lazy-load plugins stores the actual URL in the data-* section. When scrolling down, right before the image tag gets into view the data-* content is set on the src attribute to start loading the image. You can iterate through all the image

问题 Let's say I have the following: association_table = Table('things_stuffs', Base.metadata, autoload=True, extend_existing=True) class Thing(Base): __tablename__ = 'things' __table_args__ = {'autoload': True} class Stuff(Base): __tablename__ = 'stuffs' __table_args__ = ( {'autoload': True} ) things = relationship(Thing, secondary=association_table, backref=backref("stuffs", uselist=False, lazy='dynamic')) Now, if I want to get all the things from a Stuff instance I can do: a_stuff_instance

问题 Entity Framework Core 3.1.2 - I have enabled UseLazyLoadingProxies on my DbContext to ensure data integrity, but I want to throw an exception during development if it is used. How can I execute some code every time EF Core loads a relationship lazily? 回答1: The only way I know is diagnostic messages. See an example here: https://www.domstamand.com/getting-feedback-from-entityframework-core-through-diagnostics. The event class you want is https://docs.microsoft.com/en-us/dotnet/api/microsoft

问题 Scenario: I'd like to add an entity to the database that would have navigation properties and that entity has navigation properties.. and so on. Basically the tables in the database are connected with each other - all of them. I use EF4.3 and context/request pattern, so I don't want to enable Lazy loading; it would simply just take too much time to load the entity that I need. So far I have learned there is no other way to do it than to use the include method like this: context.Set<TEntity>()
