1.脚本执行概述
“脚本”面板和“脚本标签”面板概述，InDesign 包含两个用于脚本的面板：“脚本”面板和“脚本标签”面板。在“脚本”面板中可以运行脚本而不必离开 InDesign。“脚本”面板显示的是位于“InDesign 应用程序”文件夹和“偏好设置文件夹”下的”脚本“文件夹中的脚本。
选择“Windows”>“实用程序”>“脚本”打开脚本面板。如果创建或收到脚本，可将其放在“脚本面板”文件夹下，使其显示在“脚本”面板中。
macOS :Users/[用户名]/Library/Preferences/Adobe InDesign/[版本]/[语言]/Scripts/Scripts Panel
Windows XP : Documents and Settings[用户名]\Application Data\Adobe\InDesign[版本][语言]\Scripts\Scripts Panel
Windows Vista 和 Windows 7 : Users[用户名]\AppData\Roaming\Adobe\InDesign[版本][语言]\Scripts\Scripts Panel
例如作者机器上位于：C:\Users\ajz\AppData\Roaming\Adobe\InDesign\Version 15.0-J\zh_CN\Scripts\Scripts Panel
也可以放在系统脚本所在位置：C:\Program Files\Adobe\Adobe InDesign 2020\Scripts\Scripts Panel
本文开发一个功能，添加参考线。
2.InDesign 对象模型
当您考虑 InDesign 和 InDesign 文档时，您可能会在脑海中组织程序及其组件。您知道文本框架包含段落，而页面又包含文本框架。页面是跨页的一部分，一个或多个跨页组成一个文档。文档包含颜色、样式、图层和主跨页。当您考虑您创建的布局时，您会直观地理解它们是有顺序的。
InDesign 以相同的方式“思考”文档的内容。文档包含页面，页面包含页面项（文本框架、矩形、椭圆等）。文本框架包含字符、单词、段落和锚定框架；图形框架包含图像、EPS 文件或 PDF 文件；组包含其他页面项目。我们在这里提到的内容是构成 InDesign 出版物的对象，也是我们在编写 InDesign 脚本时使用的对象。
出版物中的对象按特定顺序排列：框架位于页面上，页面位于文档内，而文档位于 InDesign 应用程序对象内。当我们谈论对象模型或层次结构时，我们谈论的是这种结构。了解对象模型是找到要使用的对象的关键，而 InDesign 脚本的最佳指南是您对 InDesign 本身的了解。
对象具有属性。例如，文本对象的属性包括用于设置文本格式的字体、磅值和应用于文本的行距。
属性具有值；例如，文本的磅大小可以是数字（以磅为单位），也可以是用于自动引导的字符串“Auto”。文本的填充颜色属性可以设置为颜色、渐变、混合墨迹或色板。属性也可以是读/写或只读的。读/写属性可以设置为其他值；只读属性不能。
对象还具有方法，即脚本世界的动词，或者对象可以执行的操作。例如，document 对象具有 print、export 和 save 方法。方法具有定义方法效果的参数或值。例如，文档的 place 方法具有一个参数，用于定义要置入的文件。参数可以是必需的，也可以是可选的，具体取决于方法。
下图是 InDesign 对象模型的概述。该图不是 InDesign 脚本可用对象的完整列表；相反，它是用于理解对象类型之间关系的概念框架。
