Please help Creating a Detach Button that detaches a document I have attached with an Attach Button
Let me apologize up front for this being a bit of complicated question. I found a thread on this forum that helped me attach a file with a click of a button- now I want to detach this same file. Below is how far I've gotten.
I created a form in Adobe Acrobat DC that allows a user to attach a document to the form with a click of a button. 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
});
}
}
That process works flawlessly. What I want to do now is detach that same document with the click of another button. I understand very basic javascript but had help from the forum creating the above script. Can anyone provide me a solution (if there is one), to help me detach the file that the user attached with the script above? Thank you so much in advance!!!
