PDF JavaScript：将变量值插入表单字段

Question

我有一个带有JavaScipt的PDF，所有终端用户都运行Adobe Acrobat Pro DC。我已经成功地找到了如何让它用来自其他表单字段的值填充表单字段：

// Assuming FormFieldB has a value of "somewhere" and FormFieldA is a text box

this.getField("FormFieldA").value = "Fills a sentence and adds a string from " + this.getField("FormFieldB").value + " successfully.";

// This fills the box with "Fills a sentence and adds a string from somewhere successfully.

但我尝试做的基本上是一样的，但我尝试获取一个变量的值，并将其添加到表单字段中。

var my_variable = "somewhere";

this.getField("FormFieldA").value = "Fills a sentence and adds a string from <How do I insert from my_variable> successfully";

// I want it do write the same example sentence as before

有什么想法吗？谢谢

Answer 1

如果你使用ES6语法，你可以这样使用它：

let my_variable = "somewhere";
this.getField("FormFieldA").value = `Fills a sentence and adds a string from ${my_variable} successfully`;

"'"是ES6中引入的反勾/字符串文字运算符，它位于1键之前。

只要把琴弦串联起来...

var my_variable = "somewhere";

this.getField("FormFieldA").value = "Fills a sentence and adds a string from "+my_variable+" successfully";
