Part 3 of this series introduced the Document File Browser function, app.browseForDoc(). While useful and a relatively easy to use function, it will only browse for PDF files and cannot be used from a document script. In this tip, a much for useful, general purpose file browser dialog is introduced. Unfortunately, it is also more complex to use.
This file browser dialog has been around since Acrobat 5.0. Given the name of the function, browseForFileToSubmit(), it was probably intended to aid in using a PDF to encapsulate (embed) and transport (email) other file types. Another characteristic probably related to this intended usage is the odd manor in which the browser is activated. It is a function of the Field Object, field.browseForFileToSubmit(). This is very different from the Browse for Document dialog (discussed in Part 3), which is a member of the App Object. Being a Field Object function makes this dialog awkward to use in Folder Level scripts (for Acrobat automation).
To use this browser dialog, do the following:
Usually the browseForFileToSubmit() function is called from the MouseUp event of either the Text Field itself, or a Button. However, it is not necessary for the Text Field to be visible, so this function can be part of a larger, behind the scenes process initiated by some other user action.
// Create new temporary document, // we'll never look at it so size is unimportant var tmpDoc = app.newDoc(0,0); // Create the Text Field var fld = tmpDoc.addField("tmpTxt","text",0,[0,0,0,0]); // Set up the Text field so the file dialog can be called fld.fileSelect = true; // Display File Open Dialog fld.browseForFileToSubmit(); // save the selected file path to a local variable // so it can be used later var filePath = fld.value; // Close Document without saving tmpDoc.closeDoc(true); console.println(filePath);
The file path string uses the Acrobat Device Independent format, so a path returned from a Windows system would look like:
/c/documents and settings/me/testfiles/sample.pdf
The first part of this script calls app.newDoc(). Since this is a privileged function the code has to be wrapped in a trusted function for it to work in a menu item or toolbar button created by a Folder Level script.
