使用JavaScript遍历PDF表单中的所有字段 [英] Iterating over all fields in a PDF form with JavaScript

问题描述

我想响应用户单击按钮来修改PDF表单中所有字段的某些属性.

I would like to modify some properties for all fields in a PDF form in response to the user clicking a button.

哪个属性或方法将向我返回字段的集合，以便我可以遍历它们?

Which property or method will return me the collection of fields so that I can iterate over them?

推荐答案

如果有字段的集合，我仍然没有找到它.不过，有一种方法可以遍历所有字段.

If there is a collection of fields I still haven't found it. There is a way to iterate over all the fields though.

doc对象的numFields属性给出了字段数， getNthFieldName(index)返回具有该索引的字段的名称，而getField( fieldName )返回该名称的字段.

The numFields property of the doc object gives the number of fields, getNthFieldName(index) returns the name of the field with that index and getField(fieldName) returns the field of that name.

for (var fieldNumber = 0; fieldNumber < numFields; fieldNumber ++)
{
  getField(getNthFieldName(fieldNumber)).value = 'Scripty Was Here';
}
