In other words, I'd like to make it such that at least one of either fieldEmailAddress or fieldMobileNumber is required. It seems like most of the jQuery Validation custom methods are designed to only work for one field at a time - I need to validate both. Any ideas?

Can somebody to give me "java code" and "structure chart" examples please? 回答1: I suspect you're after something like: if (!address.contains("@") || !address.contains(".")) { // Handle bad address } EDIT: This is far from a complete validation, of course.
