Struts1.1 has been released for so long, I just started systematically learning Struts related knowledge, after the previous median research, there has been further understanding of the class Dispatchaction in Struts1.1. I will summarize here, I hope to help everyone.
In version 1.0 we usually use the Execute method to complete our process and page forwarding of business logic. Usually we can only complete a business logic in an action. If we don't have a way to complete multiple business logics (such as: add, delete, etc.), do we have a way? The answer is negative, we can define a hidden variable in the page, we can give this variable different values when different page requirements are required, and in the Execute method to complete the determination of variable values. Different business logic operations.
For example, we first define a hidden variable on the page.
Then define a JavaScript function, we can modify its value in the function body when you click the Submit button.
