JS data is divided into basic types (number, string, Boolean, null, undefined) and reference types (Object, Array, Data, REGEXP, function, etc.) two. The value of the base type variable is itself, where a=3, the value of a is 3, and the value of the reference type's variable obj={b:1},obj itself is the address of the store {b:1}, and {b:1} is the content it points to.
When you pass a value, both of your own value (A is 3,obj is the address) copies a

The JSP page uses the URL encoding to pass the Chinese parameter, in the parameter parsing process will appear garbled.

I have also recently encountered the need to pass the Chinese parameter problem. Search on the Internet, copy and paste hair everywhere is the "ultimate" "solution" is nothing more than escape (str) to transcoding, and then in the server to write a method to edit again, or with the System.Text.Encoding method to change.

Also note that I added the name attribute to the Submit button. So I can test the existence of $submit variables in the program. Then, when the page is called again, I know whether the page has been filled in with the form when it is called.

Therefore, in order to avoid confusion, we suggest that we should try not to write the data behind the address, but to put it in the data parameter.
Of course, if you want to use the Post method and get a value at the same time, you can write the data that you want to pass in the get way behind the address and write the data that you wan
