Page effect

Use $('#userForm').serialize(); to serialize the form data when submitting the form

window.opener.art.dialog({time:2,content:'Save successfully'}); is Return to the page using window.open (or understand it as the parent page), and call the artDialog plug-in's scheduled closing dialog
setTimeout(function(){window.opener.location.reload();},3); use a timer Refresh the page using window.open (or understand it as the parent page), and the time settings of dialog and reload need to be readjusted.
