There are many reasons why you can add a drag-and-drop function to your page, the simplest reason being to rearrange the data. For example, you might want users to be able to reorganize a series of page elements by placing an input or select component next to each element to represent their order as a solution so that the group element can be dragged and dropped is an alternative. Or maybe you want to have a navigation window on the site that can be moved by the user. These are simple reasons to

Android Touch event Transfer Mechanism In the previous article, I mainly explained the Touch event transfer process in the Android source code. Now I want to use a demo and an instance to learn about the Touch event handling process in Andorid.In the Android system, the three functions closely related to Touch event distribution and processing are as follows: (1) public boolean dispatchTouchEvent (MotionEvent ev) (2) public boolean onInterceptTouchE

Are some commonly used functions, there is no more nonsense, small partners to see their own understanding The code: Copy Code code as follows: Cookies function Setcookie (name, value, Iday) { if (Iday!==false) { var odate=new Date (); Odate.setdate (Odate.getdate () +iday); document.cookie=name+ ' = ' +value+ '; expires= ' +odate+ ';p ath=/'; } Else { document.cookie=name+ ' = ' +value; } } function GetCookie (name) { var arr=document.cookie.split ('; '); var i=0;

Event Review in JavaScript In fact, when I first learned JavaScript, I came into contact with a very simple line of code.alert('Hello JavaScript!!!')It explains what an event is. What is an event? Events are a very important method in JavaScript, a browser-based programming language. What is an event? In JavaScript, events can be understood as one thing that happens. The event object records all the data in this process.1. Event compatibility Processing Many browsers are classified into standard

minimum view of its inner layer), and then processed (from the smallest view cell (event source) to the outer layers. ) is implemented in the form of a.Complexity is manifested in the ability to control whether each layer of events continues to be delivered (distributed and intercepted cooperatively), as well as the specific consumption of events (event distribution also has event spending power). Three important functions involved in 2.android event processing Event Distribution:

In normal development, we often encounter events such as clicks and swipes. Sometimes there are a variety of sliding conflicts between different view. For example, if both the inside and outside of the layout can slide, then there will be a conflict. This time we need to understand the Android event distribution mechanism.IntroducedThe Android Touch event distribution process is done together in three important ways: Dispatchtouchevent, Onintercepttouchevent, Ontouchevent. Let me introduce these

Here, we recommend a commonly used javascript function encapsulated by you. basically, common operations are included. if you need it, take it directly. These are all common functions, so there will be no more nonsense here. let's take a look. Code: The code is as follows: // CookieFunction setCookie (name, value, iDay){If (iDay! = False){Var oDate = new Date ();ODate. setDate (oDate. getDate () + iDay );Document. cookie = name + '=' + value + '; expires =' + oDate + '; path = /';}Else{Docume

Cases triggered by the Android Touch event Transfer Mechanism I have also written two articles about the Android Touch event transfer mechanism. I think the Touche event is still well understood, but I have encountered a problem recently, let me learn about the Android Touche event again. My article on Android Touche event transfer mechanism is as follows: Http://blog.csdn.net/yuanzeyao/article/details/37961997 Http://blog.csdn.net/yuanzeyao/article/details/38025165 I have come to the followin

thread reads the driver event and places it in the message queue. The specific implementation is: Thread mthread = new thread ("inputdevicereader "){ Public void run (){ Rawinputevent EV = new rawinputevent (); While (true ){ Inputdevice di; Readevent (EV ); } } This thread continues to run and runs cyclically through readevent (); this function is a native method. The specific imple

of Android touch events and the source code of ViewGroup. (If you are not familiar with it, you can look at it:Android custom control Series 9: Android touch event distribution mechanism from the source code). After reading the previous article, we should know that the distribution of Andrioid events is carried out on a layer-by-layer basis. At the beginning, distribution always starts from the upper layer to the lower layer, from the Activity of the ActivityDecorViewAnd then to the layout we w

around a small change. (drop-down refresh) B, swipe left or right, diagonal slide (ad bar) The target was determined and the situation in 2 was clarified. We start from the drop-down refresh source, because this way of thinking more clear, compare event delivery, first passed from the parent class to the subclass. That process is no longer detailed, do not understand can look at other excellent blog, this is good: http://blog.csdn.net/hyp712/article/details/8777835 View Swiperefreshlayout so
