IE, Safari, Opera, and chrome all provide screenleft and screentop properties that indicate the position of the window relative to the left and top of the screen, respectively. Firefox, Safari, and Chrome provide the same window information in ScreenX and ScreenY. Opera supports ScreenX and ScreenY properties, but with Screenleft and screentop properties do not correspond, so do not use in opera ScreenX and ScreenY. Use the following code to get the window position across browsers:1 var le

PHP queries nearby locations based on a given latitude and longitude point The implementation principle first calculates the four points of the rectangle around the point, and then uses the longitude and latitude to directly match the records in the database. // Obtain the surrounding coordinates Public function returnSquarePoint ($ lng, $ lat, $ distance = 0.5 ){ $ EarthRadius = 6378138; $ Dlng = 2 * asin (sin ($ dis

This article mainly introduces how to obtain IP addresses and share geographic locations in PHP. in this article, the general interface of SINA is used for geographic location, if you need a script, you can refer to it and find that the script has not been written. The classic logic is used to obtain IP addresses, and the common interface of SINA is used for geographic location. For details about the usage method, see the source code: The code is as

, and the size of each chunk can be clearly known. Heap is no structure data can be stored arbitrarily. Therefore, the stack is addressed faster than the heap.In general, each thread allocates one stack (stack) per process to allocate a heap. That is, the stack is an exclusive thread and the heap is a shared thread. so local stack heap inside local variable Once run end recycling and Span style= "Font-family:consolas;" >heap GC Span style= "font-family: the song Body;" > The

referenced JavaScript code, the benefits are obvious:1. Avoid using JavaScript code2. Avoid the use of unsightly CDATA3. Common JavaScript code can be reused for other HTML documents, as well as for consistent JavaScript code maintenance4.HTML document is smaller, facilitate search engine included5. A single JavaScript file can be compressed and encrypted6. Browsers can cache JavaScript files and reduce broadband usage (usually only once when multiple pages are using a single JavaScript file)7.
