FormValid0.5 is released, with examples of ajax custom Verification

The latest update changes. When the input component name contains [], a JS error occurs when the focus is moved to the component. This is the case only for IE, and no good solution is found, I just excluded this situation, that is, when the component name contains [] and the focus is not moved up, please contact me if there is a good solution.
