问题 I have some hidden input values that I would like to have be changed to a certain value once a user clicks on a link. 回答1: $('.someLink').click(function(){ $('.someHiddenInput').val('new value'); }); I think this is what you mean.

问题 I'm trying to create a form that pops-up an error when people insert a specific zip code or range of zip codes. For example: If a potential lead fills out a form and enters a Washington state zip code I'd then want an error to pop-up to say we don't offer the product in that state.
