THotPDF.AddLoadedDocumentJavaScript Method

Adds a named script entry to the named JavaScript collection of the loaded PDF document, making it execute automatically at the document level

Declaration

procedure AddLoadedDocumentJavaScript(const AName, ABody: AnsiString);

HPDFDoc

Name	Purpose
`AName`	The unique name of the script entry, used to identify and reference this script in the name tree; it can also be deleted by name via RemoveLoadedJavaScript
`ABody`	The complete body code of the JavaScript script, executed by the PDF reader when the document is opened

若文档已存在同名脚本，此方法将覆盖现有条目，而不会创建重复项
The execution of document-level JavaScript relies on the PDF reader's support for scripts; Adobe Acrobat has the most complete support, whereas other readers may ignore this script
If the script code contains special characters, they must undergo PDF string escaping; it is recommended to verify the script logic in Acrobat before embedding
