When the content of observable changes, observable notifies all data-bound controllers, so they are able to update themselves. (whereas the observable class is a observable array version.) Starting with this, our view model has two observable:1, books Maintain books list.2, error contains errors if the AJAX call failsThe Getallbooks method generates an Ajax call to get the b

One thing to note here is that the person class on the server is exactly the same as the client class (including the package name), otherwise there will be exceptions such as:Well, after a few steps, we can pass an object from the Android client to the server, which is as simple as eliminating the hassle of converting objects to JSON or XML.Android Demo Down
"Subscribechildrenchange" method are triggered in the following situations:
Node is created
node is deleted
Nodal node changes
ZK Connection re-connected successfully
How do I differentiate the state of a node in the "Xxxxchange" event?There is a property "type" with the type "EventType" in the event trigger parameter, which clearly distinguishes the cause of the node change. Why write this program, what is it different from "Zookeeperex"?The official components provid

Use the Select function to communicate with multiple sockets in a non-blocking manner. The program simply demonstrates the use of the Select function, which is very simple, even if a connection is closed and the current number of connections is not modified, and the program is terminated after the maximum number of connections is reached.1. The program uses an array fd_a, and the communication begins after the multiple socket descriptors that need to be communicated are placed in this array.2. F
