programs that can generate static pages are popular on the Internet. They are "semi-automatic" html generation by manually clicking the "generate html page" button in the background. However, portal websites with a large amount of information do not work. Static pages are called static pages because they cannot be changed automatically. If the information list is updated 100 times a day, the static list page will be re-generated 100 times. If I have
there are so many benefits to data binding. Document model methods are basically required in the following two main scenarios:
When the application is really concerned with the details of the document structure. For example, if you are writing an XML document editor, you will want to adopt a document model instead of using data binding.
When the document being processed does not need to follow a fixed structure. For example, data binding is not a good way to implement a regular XML document d

When I was in school, I always felt that automatic code generation was not very reliable and I used it too. At that time, I found that the names of automatically generated code variables were chaotic and I was basically not interested. After work, I used Automatic code generation
conversion to easy language text, it is best to perform the encoding conversion (UTF-8 = GB18030), otherwise Chinese garbled. This is a very simple step, just as a post-school assignment.We can completely improve this proxy function, or write another proxy function that supports different types of user functions (such as different parameter types and number of parameters and return value types).The rest of the user function is simpler, and here's just a general example (this function is used in
