Answer 2

Shoban让我走了，这就是我的解决方案：

function validate_form(thisform)
{
with (thisform)
{
if (validate_required(drop_point,"Please choose a Drop Point")==false)
{drop_point.focus();return false;}
if (validate_required(first_name,"Please enter your First Name")==false)
{first_name.focus();return false;}
if (validate_required(last_name,"Please enter your Last Name")==false)
{last_name.focus();return false;}
if (validate_required(drop_point_date,"Please enter the Drop Point Date")==false)
{drop_point_date.focus();return false;}
if (validate_required(email,"Please enter your Email Address")==false)
{email.focus();return false;}
if (validate_required(order_confirm,"Please confirm your order")==false)
{order_confirm.focus();return false;}
}
return confirm("Do you want to submit the form");
}

这很有效！

非常感谢！生活和学习！
