How can we use javascript to get a list of attachments currently attached to our PDF document?

Thanks in advance,

Loop throught the dataObjects.


var d =;

if (d != null)

for (var i = 0; i < d.length; i++)


console.println("Data Object[" + i + "]=" + d[i].name);

Thanks Mark for the tip.

I am using LiveCycle Designer ES to make the form, using javascript to get my functionality.

I tried to access the attachment names with your advice, by looping through the dataObjects. But it always gives the name "Untitled Object" no matter which document I attach.

I have tried to find resources to look for objects and properties that I need to check. From you I got to know that I need to look into the "dataObjects" object.

Also, I am wondering how to update my list of the attachments when the user adds or removes the attachments. Which event (where) should I place the code for updating my list.

Please help.

You can retrieve more info about your data objects.

app.alert("Data Object[" + i + "].path=" + d[i].path);

app.alert("d.MIMETyle: " + d[i].MIMEType);

Path is probably the one you want.

The "Acrobat JavaScript Scripting Reference" describes the methods & properties available. You can usually find it via Google.

The list of attachments should be automatically updated if the user is using the UI features to add/remove attachments.

Good Luck

Hi Mark,

Could you please tell how to read/display the contents of the attached file.

For eg: d[i].name gives me the name of the attached file.

Similarly do we have some d[i].<properties> to get the contents of the attached file?

Thanks and Regards,
