$( "#pin_Email" ).blur(function(){ var re = /^(([^<>()[\]\.,;:\s@\ "]+(\.[^<>()[\]\.,;:\s@"]+)*)|(".+" ))@(($$[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$$)|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/; return re.test($( this ).val()); }); it will return true or false based on the value inserted in mail input and press tab or focus out.
