Javascript to Embed file attachment
I found a Javascript on the forum that allows me to have a form user attach a file in Adobe Reader to a PDF form. The script is below and works great...as long as I am viewing the saved document on a computer. I have discovered that Adobe Reader Mobile doesn't recognize file attachments added as annotations (only embedded files). Can someone help me modify this script so that the file is actually embedded and not added as an annotation? My follow-up question is the javascript to detach the file with a button. I am using Adobe Acrobat DC to program the form. Thank you so much for your help!!!
The way this is programmed is that on the button itself with a Mouse Up action, the following Javascript is run:
if (app.viewerVersion < 11) {
import_pre_11();
} else {
import_11();
}
Then there is a document level javascript for attaching the file that is programmed like this:
// Initialize attachment number
attachment_num = 1;
// Initial location of file attachment icon
// The x value is incremented below
var oFAP = {x_init: -72, x: -72, y: -72}; // Below lower-left corner of the page
function import_pre_11() {
if (app.viewerType === "Reader") {
app.alert({
cMsg: "You must user Reader version 11 or later to attach files to this form.",
cTitle: "Attach File Error",
nIcon: 3,
nType: 0
});
return;
}
// Prompt user to import a file
app.alert({
cMsg: "Click the OK button to select a file from your system.",
cTitle: "Attach File",
nIcon: 3,
nType: 0
});
try {
var rc = this.importDataObject("Attachment" + attachment_num);
if (rc) {
attachment_num += 1;
app.alert({
cMsg: "Attachment successful.\r\rOpen the Attachments panel to access the attached file(s).",
cTitle: "Attachment Successful",
nIcon: 3,
nType: 0
});
} else {
app.alert({
cMsg: "Attachment cancelled.",
cTitle: "Attachment Cancelled",
nIcon: 3,
nType: 0
});
}
} catch (e) {
app.alert({
cMsg: "Could not attach file.",
cTitle: "Could not attach file",
nIcon: 3,
nType: 0
});
}
}
function import_11() {
try {
var annot = addAnnot({
page: event.target.page,
type: "FileAttachment",
author: "Form user",
name: "File Attachment",
point: [oFAP.x, oFAP.y],
contents: "File attachment on: " + util.printd("yyyy/mm/dd HH:MM:ss", new Date()),
attachIcon: "Paperclip"
});
annot.cAttachmentPath; // Prompt user to select a file to attach
oFAP.x += 18; // Increment the x location for the icon
} catch (e) {
app.alert({
cMsg: "Could not attach file.\r\rPlease report this error.",
cTitle: "File attachment error",
nIcon: 3,
nType: 0
});
}
}
