URL rewriting turned on?

When parsing the html page, are you sure that your U method has been parsed? The specific operation is: check the page source code.

XmlResquest.. It means that ajax cannot submit this url link (premise, ajax is invalid)

Later I found out that there was no problem with my U command. I submitted it to the corresponding method. I was confused when I wrote it. It was display() that was wrong. It should be display('Indexindex');
