A declaration allows us to declare a variable at a page level in a template, or even another containing page. A declaration looks like the following code:We are able to use the declaration in the template file:
...In this example, we declare some page variables. The first 3 variables are already assigned in Actionobject in the action class we created: Data.getvaluebean (' Sale_month '). The 4th variable is assigned a string value: Salesareaid = "Central District".The declare

MVC is a common program structure in web development.The simple mvc structure is as follows:View layer: Display layer.Control Layer: business layer, which combines various actions.Model layer: model layer. It generally deals with data. Simple sample: a table corresponds to a model class.The control layer calls the model layer method to access data.To a certain extent, the code can be clear, easy to expand, and the complexity of code management is low.
In Thinkphp3.0, there is a URL question that now has a form to submit action = quot ;__ URL _/functionName quot;. how to implement this? how to call the functionName function of this class to process the submitted content, let me give you an address ., It mainly deals with routing. Major Thinkphp3.0 URL problems
Now there is a form submission action = "_ URL _/functionName". how can this be implemented? how can I call the functionName function of t
role: You can have one or more subsystems at the same time. Every subsystem is not a separate class, but a collection of classes. Each subsystem can be called directly by the client or by the facade role. The subsystem does not know the existence of the facade. For the subsystem, the facade is just another client.

Modern software systems are complex. A common method for designers to process complex systems is to divide them into several smaller subsystems.

In particular, the getboundingclientrect method can obtain the coordinates and sizes of element nodes at a speed. At last, W3C finally got stuck and unified them with some methods for processing styles, called cssom (Cascading Style Sheets object model, stacked style table object model ).

Dr. Yan Hong's book "Java and patterns" describes the facade mode in this way:
The facade mode is the object structure mode. External communication with a sub-system must be performed through a unified facade object. The facade mode provides a high-level interface to make subsystems easier to use.

after doing so, I will give a clear explanation of all this. So I hope you can read it.
You can see that I split the above into three parts.
C: components that support Silverlight installation and update. It can also be said that C is what we call plug-ins, but not completely.
Integrated Network Protocol Stack: It is required for network communication.
Dom integration: It is necessary to communicate well with the browser. Silverlight cannot deal with the browser.

The policy mode encapsulates easy-to-Change behaviors so that they can be replaced with each other, so that these behavior changes are independent of customers who own these behaviors.
Gof "design patterns": defines a series
Algorithm, Encapsulate them one by one, and make them replace each other. This mode allows algorithms to be independent from their customer changes.
The command mode is an object behavior mode. It mainly solves the following problems: During the software build process,

include can do the same, just import your own CSS file. This method is simple and clean, but it may produce many small CSS files.
For example, if the footer style requires only 20 lines of CSS code, creating a single file will not work. And this method will cause each page to contain a bunch of CSS files--because of how many include, how many CSS files.

Java has both kinds of classes for input and output (I/O): Streams and readers/writers.
Streams (InputStream, outputstream and everything that extends these) is for reading and writing binary data from files, The network, or whatever other device. Readers and writers is for reading and writing text (characters). They is a layer on top of streams, which converts binary
