respond to the same event on different elements. Another thing to remember is that when an event is propagated to a parent element, you can stop it and overwrite the default behavior of HTML elements (such as links. However, sometimes this is not a good idea, because browsers give HTML elements the behavior for a reason. For example, a link may point to a target on the page. without modifying them, you can add the current Script status of the page to the bookmarks. 6. Think for others (Name

xserver can be directly displayed, which saves a lot of space.The ximage data interface has a Data Pointer, but it does not exist in the SHM version. It will contain an address. Xshmimage. These contents are written by memory and may be missed. In other words, the corresponding processing process of xvideo on the xserver side.Xserver will receive xshmputimage request, which is implemented in the xserver xorg-server-1.5.3/xext/SHM. c Static intSprocshmputimage (client)Clientptr client;{Register

This article mainly explains:Processing of---sed text blocksI. Processing of SED text blocks1. Basic usage of SED text block processingCommon processing options are: Insert text before line IInsert text after line aC Replace when forwardWhen you need to insert multiple lines of text, one method is to "\ n" for wrapping, and the other to be delimited with "\". This method may be more consistent with reading habits.Use "" to invoke the entire lookup string in the S-replace operationOr with a test

modifying them, you can add the current Script status of the page to the bookmarks. 6. Think for others (namespace, scope and mode) Your code is almost never the only script code in the document. Therefore, it is especially important to ensure that no other scripts can overwrite global functions or global variables in your code. There are some available modes to avoid this problem. The most basic point is to use the VaR keyword to initialize all variables. Suppose we have written the following

Article Title: Mozilla will be able to dig corners for Ubuntu bosses. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Mozilla touches talents from the boss of Ubuntu Mark Shuttleworth, the famous boss of Ubuntu/Canonical, probably won't even dream of it. Mozilla will dig people from the Shuttleworth Foundation, a charity he founded, to run Mozilla. Mark Sur

multiple convex polygon, such as a triangle. The algorithm can be used to move a polygon quickly or slowly. Collision will not be lost no matter how fast the object moves. It can also deal with overlapping issues and promote the separation of overlapping objects. The demonstration also supports splitting polygon crossover. This can be used for bullet modeling. It also provides a simple object system, elasticity, basic friction and static friction. Used to ensure that the object does not slide f

90 's your computer often crashes? Yes, I'm sorry.When I was 17 years old, I had nothing to do, so I taught myself to program it. So I decided to write a virus myself.Don't worry. I completed the two viruses leprosy and leprosy-b are for MS-DOS computers. They have nothing to do with the Internet, because they haven't. Now they are as extinct as smallpox.I want to write these things that are bad for someone else's computer for a lot of reasons. First of all, like I said, I was 17 years old. In a

is the block that tells you which pixels the triangle covers, and in some cases it gives the coordinates of the center of gravity of those pixels in the triangle. But that's the only thing. Not only does not give u and V, not even 1/z.Of course there are no textures and shading, but these are not a thing by using dedicated textures and shader units. Second, if you have written your own triangular mapper, you might have used an incremental scanline raster algorithm like Chris

default behavior of HTML elements (such as links). However, sometimes this is not a good idea, because browsers give HTML elements that behave for a reason. For example, a link might point to a target within a page and not modify it to ensure that the user can bookmark the current script state of the page.6. For the sake of others(namespaces, scopes, and schemas)Your code is almost never the only script code in the document. So it is important to ensure that there are no global functions or glo

. After creating the dialog box instance, you can reload the onPrepareDialog method to modify the dialog box before showDialog. Similar to how Android manages menus. The following describes how to use AlertDialog. Because onCreateDialog may create multiple Dialog examples, you must first define a Dialog ID.

declare a function in a non-function block and assign that function to a variable. The Browser allows you to do this, but the parsing is different. Note: The ECMA-262 definition defines a block as a set of statements, and the function declaration is not a statement. Read the ECMA-262's explanation of this problem.// badif (currentUser) { function test() { console.log('Nope.'); }}// goodif (currentUser) { var test = function test() { console.log('Yup.'); };} Do not name the parameter

Exercise 40: A dictionary, a lovely dictionaryNext I'm going to teach you a different kind of container-type data structure, because once you've learned this kind of container, you're going to have super cool power. This is the most useful container: the dictionary (dictionary).Python calls this data type "Dict", and in some languages its name is "hash". I'll use both of these names, but it doesn't matter, it's the difference between them and the list. You see, for a list you can do something li
