behavior

问题 How are the modified scroll behaviors on websites made? I want to accomplish an accelerated scroll behavior as you can see it in the example. So you scroll in a certain speed and after you let go the page scrolls a little more by its own, slows down and stops. Unfortunately I have absolutely no basis to provide you with code, I hope you can still help me. Maybe you can recommend me some js plugins? https://p2mv.studio/case/sony-music-france 回答1: You have 2 ways of achieving this. You can use

问题 Using GCC: printf("%i \n", -1 % (int)4); printf("%u \n", -1 % (unsigned int)4); Output: -1 3 Can I rely on this behaviour across platforms? Should I explicitly define MOD and REM macros to be sure this isn't altered? 回答1: From C99 onwards the result of % is required to be rounded toward 0 as quoted by Chris Dodd. Prior to C99 standard, % operator's behavior on negative number is implementation defined . When integers are divided and the division is inexact, if both operands are positive the

问题 I need to implement BottomSheetDialogFragment and face with the problem. I need that my BottomSheetDialogFragment has fixed height. Does anyone has an idea how to do it? Here is my xml of fragment content <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="@dimen/bottom_sheet_height" android:background="@android:color/white" android:orientation="vertical"> <TextView android:id="@+id/drag_title" android:layout

问题 I am running this query on SQL Server 2012: select 'weird' where '' = 0 It's returning 'weird' . As far as I understand, '' is quite different from 0 . So please explain why the above happens. Thanks 回答1: So, taking a look at the data types where they stand in the WHERE clause SELECT SQL_VARIANT_PROPERTY(0, 'BaseType'),SQL_VARIANT_PROPERTY('', 'BaseType') They return int, varchar respectively. When comparing two different data types, the data type with the lower precedence will convert to the

问题 I want two of my models to inherit a property and a couple of methods. I know I could put the methods in a behaviour but I'm not sure about the property. Can a behaviour have variables that are inherited by the model? Or should I just create another model that extends AppModel, and have the two models extend that one? 回答1: As long as both methods and variables are made public you can put your code into a behavior. In general I would go for a behavior, I guess. You could then create some

问题 I'm using erlang as a bridge between services and I was wondering what advice people had for handling downed connections? I'm taking input from local files and piping them out to AMQP and it's conceivable that the AMQP broker could go down. For that case I would want to keep retrying to connect to the AMQP server but I don't want to peg the CPU with those connections attempts. My inclination is to put a sleep into the reboot of the AMQP code. Wouldn't that 'hack' essentially circumvent the

问题 Let's say I have 4 activities in my app: A (main activity) B C D I would like that pressing back in Activity A always produce application exit. In my case if activity flow goes like this A > B > C > A, then if I push back button, I will go to activity C. I want, at that moment, my app to exit. I assume, app should somehow delete activity history when main activity is active. How is this to be done? Thanks 回答1: When you launch your home activity do so with the clear top flag set. This causes
