我发现了以下内容:
$('body').on('keydown', 'input, select, textarea', function(e) {
var self = $(this)
, form = self.parents('form:eq(0)')
, focusable
, next
;
if (e.keyCode == 13) {
focusable = form.find('input,a,select,button,textarea').filter(':visible');
next = focusable.eq(focusable.index(this)+1);
if (next.length) {
next.focus();
} else {
form.submit();
}
return false;
}
});
但是如何使下一个值突出显示(表现得像TAB)/
