从表单动态添加数字。 [英] Dynamically adding numbers from a form.
问题描述
你好....免责声明......我是新手:)
我试图添加2个字段并获得总额
字段1将是一个列表字段。显示4个选项
每个选项都有一个数字关联（即选择1 = 40，选择2 = 80等）
字段2将是另一个列表字段...显示4个选项
如果选择1 = 40，如果选择2 = 80，等等）
汇总Calc会将Field 1和Field 2加在一起。我宁愿这样做而不改变页面，所以我猜javascript将是最好的选择....
任何帮助将不胜感激...谢谢！

Hello....disclaimer...I am a newbie :)
I am attempting to add 2 fields and obtain a total sum
Field 1 would be a list field. Showing 4 choices
Each choice has a number association (ie choice 1 =40, choice 2 = 80, etc)
Field 2 would be another list field...showing 4 choices
If choice 1 = 40, if choice 2 = 80 ,etc)
Summary Calc would add Field 1 and Field 2 together. I would prefer to do this without changing pages so I am guessing javascript would be the best choice....
Any help would be appreciated...thanks!

您好，感谢您的帮助！
我的想法是，只要列表被更改，表单总数就会动态更新。目标是总计费用金额，以便该人知道他们的费用，金额可以发送到PayPal payflow链接进行信用卡支付。
这是一般的想法：
Hello and THANKS for helping!
My idea was that the form total would dynamically update anytime either list was altered. The goal was to general the totalfee amount so the person would know their fees and the amount could be sent to paypal payflow link for credit card payment.
Here is the general idea:
定义一个函数，例如
Define a function, e.g.
