How to automatically calculate the value of a text field in Adobe Acrobat with javascript based on the contents of another text field?
提问by jkupczak
I've got a fillable PDF form my client is using for taking orders. It includes a chart with various fields and multiple rows that all end in a "Subtotal" field. I want to automatically calculate this subtotal field so that the user does not have to punch in the currency themselves.
我有一个可填写的 PDF 表格，我的客户正在使用它来接受订单。它包括一个具有各种字段和多行的图表，这些行都以“小计”字段结尾。我想自动计算这个小计字段，这样用户就不必自己打入货币了。
The value of that field needs to be based off of another field. The user fills in this other field with the total quantity they want. I need to automatically take the quantity they enter and multiply it by a price that I set myself.
该字段的值需要基于另一个字段。用户用他们想要的总数量填写另一个字段。我需要自动获取他们输入的数量并将其乘以我自己设定的价格。

youll have to do something like this
你必须做这样的事情
this.getField("total").value = this.getField("filed1").value + this.getField("filed2").value;
