With the development of browser technology, HTML5, CSS3 and so on, more and more rich Web applications appear, while the Web developers need to deal with more and more asynchronous callback logic in the background while giving us a good experience.The author of the recent reading of the "async javascript-build more responsive apps wi

have been writing jquery code before the encounter AJAX load data need to consider the sequence of code running problems. The most recent projects have been synchronized with Ajax. This synchronization means that when the JS code is loaded into the current Ajax will put all the code in the page to stop loading, the page out of suspended animation, when this Ajax execution will continue to run the other code page suspended animation state. Asynchronous

After learning the basic concepts from Tutorial, we will enter the actual practice stage. Through learning, we will provide a small connection example, a synchronization example, and an asynchronous example. Ing between types and gtypes In D-Bus programming, the following table lists the mappings between basic types an

Ajax is a technique for creating fast, Dynamic Web pages. A small amount of data exchange with the server in the background. Ajax makes it possible for Web pages to be updated asynchronously.

Sequence of operations for asynchronous programs61 describes how the asynchronous API performs potentially costly I/O operations without blocking the application from continuing to process other inputs. Understanding the sequence of operations of asynchronous programs is just beginning to get a little confusing. For example
