In javascript, we need to obtain the coordinates of the mouse position in several ways. One is the relative position (browser window, document location). Almost all of these are using document. body. scrollTop, document. body. dom commands such as scrollLeft. I will introduce several instances in detail below. Example 1 The Code is as follows: Copy code Var xPos;Var yPos;Document. onmousemove = mouseMove;Function mouseMove (ev

handles, which can be forcibly converted to socket handles directly. Before encapsulating epoll, another step is to define a Data Structure to store data with an indefinite length so that it can be mounted to epoll events. struct mdata{ int fd; unsigned int len; char buf[2048]; mdata(){} mdata(char *s,const int length) { for(int i=0;i Epoll encapsulation can be started and edge-triggered. My idea is to record the epoll handle and parameters in the class, and maintain

The event types in android include button events and screen Touch events. Touch events are the basic events of screen Touch events, so it is necessary to have a deep understanding of them.A simple screen Touch action triggers a series of Touch events: ACTION_DOWN-> ACTION_MOVE...-> ACTION_MOVE-> ACTION_UPWhen the screen contains a ViewGroup and the ViewGroup contains a sub-view, how does the android system handle Touch events? Is ViewGroup used to process Touch events or child views used to proc

Copy code code as follows: var restrictx; var restricty; var tip; Mouse coordinates function mouseposition (EV) { return { X:ev.clientx + Document.documentelement.scrollleft-document.documentelement.clientleft, Y:ev.clienty + document.documentelement.scrolltop-document.documentelement.clienttop }; } Mouse events function MouseMove (EV) {

element's focus obj.select () selects the text contents of the specified element selected Is the user input content, the contents of the DIV is not an event object, when an event occurs, some detailed information about the event that occurs with the current object will be temporarily saved to a specified place-event object, for us to call in the need. Aircraft-black Box The event object must be used in a function called by an event to have a content event function: The function called by the ev

the ev_watcher struct can be considered as the base class for all ev_type structures, which contains the same fields in all Ev_type. These structures are defined in the code as follows, and I have restored some of the macros for ease of understanding. Only partial macros are restored, not all, because these macros embody the idea of the author designing these structures. Related macros 1 2 3 4 5 6 7 8 9 17 This macro defines all parts of the Ev_type beginning #define Ev_watcher

variables have the following meanings: FD: Event-related device handle.

Jquery short right-click menu compatible with ie6ie7ie8firefoxchrome The Code is as follows: $ (Function (){Document. oncontextmenu = function () {return false;} // right-click to blockDocument. onmousemove = mouseMove; // record the mouse position});Var mx = 0, my = 0;Function mouseMove (ev) {Ev = ev | window. event; var mousePos = mouseCoords (

this Code is that xPos and yPos change in real time. The second code is to use a function to obtain the mouse coordinate value of the current time. The Code is as follows: Document. onmousemove = mouseMove;Function mouseMove (ev ){Ev = ev | window. event;Var mousePos = mouseCoords (ev );}Function mouseCoords (
