Validate prefilled jQuery form (invalidate on first field clear, ASP.NET and unobtrustive)

Question

I have a form that can be filled, saved, loaded and re-edited.

When it is loaded and re-edited, it probably begins its life valid. When a field is valid upon

Answer 1

You could try validating the form manually each time an input was changed.

$(":input").live("change", function(){
    form.validate();
})

From looking at the documentation it seems that you can't call form.valid() without calling form.validate(); first.
