Traditional applications have two application modes: desktop applications and Web applications. WPF navigation applications blur the boundaries between these two types of applications.
WPF navigation is represented in two forms: one is to host the navigation content i
, so there are a lot of people who suggest using Angularjs, don't mix jquery. Of course, both have their pros and cons, and use whichever depends on their choice.The app in Ng is equivalent to a modular module that can define multiple controllers in each app, each with its own scope and without interfering with each other.Look at the HTML below:You will be pleasantly surprised to find that even without writing a line of JS code, you can finish computi

NCLOBStores large NCHAR character data types. Each variable stores the location of a large character object, which refers to a large character data block. Size of a
1. Angularjs uses $injetor(injector service) to manage queries and instantiations of dependencies. In fact, $injetor is responsible for instantiating all of the components in the ANGULARJS, including the application's modules, instructions, and controllers. At run time, when any module starts, $injetor is responsible for instantiating and passing all the dependencies it needs.Dependency injection in a way t

the need for a book like Angularjs, but because the version is updated quickly, Angularjs's code cannot be copied. But understanding the framework design ideas after the development process, you can look at the constantly updated API reference is OK.In the second half of this year, the Chinese version of the comprehensive popular Ng-book (base involved in translation) may be introduced, and the promotion of angul

After sharing this series of articles last time a friend also suggested that 1.x version in addition to maintenance is not necessary to learn, you can learn 2.0 to start learning, I also know 1.x no matter from the performance or architecture are not 2.x good, but I think because there are some friends still in the 1.x version, because 1.x upgrade to 2.x difficult, even can be said to refactor, To our company is still in the 1.x version, so I decided

the change event of message, so that the code to check the remaining words must be thought of as a message event, similar to this:$("#message").change(function({ $("#leftwordcount").text(left());});Now that the remaining words correspond to the Ng-bind event of span, you can see where this logic is implemented, and it's easier to find the implementation method to make it easier to maintain this implementation.Iii.
