Push button support

I am evaluating ASPOSE.PDF and I have a few questions:

1. Using ASPOSE, can I generate PDF file with buttons that submit the form to a web server?

2. Can I inject Javascript into the PDF file? I need to do forms validation and sub-totalling.

3. We need to have users enter data into the form fields. I assume that this can be done.

4. Can I open an existing PDF file and make modifications? For example, replace tokens

Dear Mitch,

Thank you for considering Aspose.

1. Buttons are supported in FormField but submitting the form to a web server is not supported;

2. JavaScript is not supported. We will consider supporting this feature later.

3. It is supported as you said.

4. Modifying existing PDF is supported in Aspose.Pdf.Kit. But replace tokens is not supported yet. I think that function will be supported soon.

Hello Toan,

Thanks for considering Aspose.

Before commenting over calling function calling in javascript over pdf, can you please expalin the detials of function which you need to call ?

Let me share something with you, Acrobat javascript does not have access to objects within an HTML page. Similarly, HTML javascript cannot access objects within pdf file.

If I understand you correct, you want to update JavaScripts in existing PDF. That is not supported in the current version of our products. We will investigate this issue and try to support it in the future version.

Dear Mitch,

Thanks for considering Aspose.Pdf.Kit.

For your question:
1. Using ASPOSE, can I generate PDF file with buttons that submit the form to a web server?
I would like to add some more comments.

Actually FormEditor.AddSubmitBtn() can add a submit button to existing PDF template,e.g.:

FormEditor formeditor = new FormEditor( "addSubmitBtn.6.in.pdf", "out.pdf");
String mailurl = "mailto:Luke.fu@aspose.com";
formeditor.AddSubmitBtn("SubmitBtn1", 1, "Mail to Me",mailurl, 50, 760, 130, 778);
String httpurl = "<A href="</FONT></A><FONT color=#0000ff size=2>";
formeditor.AddSubmitBtn("SubmitBtn2", 1, "Submit",httpurl, 250, 760, 330, 778);

While FormEditor.SetSubmitUrl() can change the submit url of a submit button, e.g.:

FormEditor formeditor = new FormEditor("input.pdf", "output.pdf");
formeditor.SetSubmitUrl("SubmitBtn1", "www.aspose.com");
formeditor.SetSubmitUrl("SubmitBtn2", "mailto:luke.fu@aspose.com");

I am not sure whether they would fullfill your requirement completely, please test it.

Best regards.
