Summary

Object.defineProperty(LoadDocumentOptions.prototype, 'password', 
   get: function(), 
   set: function(value) 
) 
password: string; 

Property Value

The password to use if the document is encrypted. Default value is null.

Remarks

Some documents such as PDF can be encrypted and required a password before it can be parsed. You can set the password here or call Decrypt after the document is created. For more information, refer to Loading Encrypted Files Using the Document Library.
