Thus, I want to create a dynamic regular expression based on the input to the function. I may need to pass variable number of variables at a time for comparison, so how can that 'or' factor be inserted in the regex? Is it possible to create such a regular expression in Java, and how should I go about it? 回答1: Yes, the regex is only a string, you can

问题 Hi I'd like to make it so that the user can click a "upload more files" button to create an additional file upload form field and they can also click another button called "add more names" to create an additional "input type='text'" form field.
