Question

我正在尝试使用脚本从DOB中获取用户年龄，然后根据这个年龄奖励他们分为两个区域联邦（f）和魁北克（q）移民，因为他们都计算年龄点我有一套of if ... else命令奖励积分并在两个文本框中显示。目前用于计算点的脚本parseInt是显示年龄的文本字段（此字段由dobtoage脚本填充）继承我的代码和live preview。

首先，你很奇怪地计算年龄。

这样做：

var today = new Date(); 
var bday = new Date(d[2],d[1],d[0]);
var age = today.getFullYear() - bday.getFullYear();  //If you're born in 1980 then 2011-1980 means you're about 31 years old, this will give you the age if birthday has already passed

if(today.getMonth() < bday.getMonth() || (today.getMonth() == bday.getMonth() && today.getDate() < bday.getDate()))  
{
     age--;  //Reduce age by 1 if birthday hasn't passed
}

对于巨大的if ifif结构，首先我将其分解为两个独立的结构。这使您可以利用另一个中没有的范围来缩短整体结构。年龄范围如此混乱，我真的不想通过它来构建适当的结构。可能希望利用switch case语句而不是if / elseif / else。

此外，将您的功能放在他们所属的头部。此外，如果ShowAge（）函数不是有效日期，则需要对其进行一些错误检查。此外，您需要在表单的ID上使用getElementById在最后更改ShowAge()中的值，否则它不知道form是什么。因此，请为您的表单添加ID，并将ShowAge()的结尾更改为：

document.getElementById('formid').age.value = age;

尝试从DOB派生Age，然后使用if..else语句计算点数
