Examples

Shows how to work with built-in document properties.

let doc = new aw.Document(base.myDir + "Properties.docx");

// The "Document" object contains some of its metadata in its members.
//console.log(`Document filename:\n\t \"${doc.originalFileName}\"`);

// The document also stores metadata in its built-in properties.
// Each built-in property is a member of the document's "BuiltInDocumentProperties" object.
/*console.log("Built-in Properties:");
for (let docProperty of doc.builtInDocumentProperties)
{
  console.log(docProperty.name);
  console.log(`\tType:\t${docProperty.type}`);
  console.log(`\tValue:\t\"${docProperty.toString()}\"`);
}*/

Shows how to work with a document’s custom properties.

let doc = new aw.Document();
let properties = doc.customDocumentProperties;

expect(properties.count).toEqual(0);

// Custom document properties are key-value pairs that we can add to the document.
properties.add("Authorized", true);
properties.add("Authorized By", "John Doe");
properties.add("Authorized Date", Date.now());
properties.add("Authorized Revision", doc.builtInDocumentProperties.revisionNumber);
properties.add("Authorized Amount", 123.45);

// The collection sorts the custom properties in alphabetic order.
expect(properties.indexOf("Authorized Amount")).toEqual(1);
expect(properties.count).toEqual(5);

// Print every custom property in the document.
/*for (let p of properties) {
    console.log(`Name: \"${p.name}\"\n\tType: \"${p.type}\"\n\tValue: \"${p.toString()}\"`);
}*/

// Display the value of a custom property using a DOCPROPERTY field.
let builder = new aw.DocumentBuilder(doc);
let field = builder.insertField(" DOCPROPERTY \"Authorized By\"").asFieldDocProperty();
field.update();

expect(field.result).toEqual("John Doe");

// We can find these custom properties in Microsoft Word via "File" -> "Properties" > "Advanced Properties" > "Custom".
doc.save(base.artifactsDir + "DocumentProperties.DocumentPropertyCollection.docx");

// Below are three ways or removing custom properties from a document.
// 1 -  Remove by index:
properties.removeAt(1);

expect(properties.contains("Authorized Amount")).toEqual(false);
expect(properties.count).toEqual(4);

// 2 -  Remove by name:
properties.remove("Authorized Revision");

expect(properties.contains("Authorized Revision")).toEqual(false);
expect(properties.count).toEqual(3);

// 3 -  Empty the entire collection at once:
properties.clear();

expect(properties.count).toEqual(0);
