阅读更多关于 Manually bind JQuery validation after Ajax request

问题 I'm requesting an ASP.net MVC view into a live box and the view contains form fields that have been marked up with attributes to be used by JQuery's unobtrusive validators plug-in.

Thus how can I let the validation framework know that it has new form fields to fix up?

Some of my forms require a custom submit handler (which conditionally pops-up a confirmation dialog before submitting, independent of validation). I attach the handler to the form like so: function confirmHandlerAttach(form, handler) { $(form).off("submit", confirmHandlerDefault); $(form).on("submit", handler); } Both validation and the submit handler are attached at doc ready based on classes. Independently,
