How do I programmatically execute Javascript or run action?

[msadovskiy]

I am filling an editable pdf programmatically. But the pdf has those form fields where it puts one letter per box. There is a javascript being executed on focus and on blur that spaces the letters when you type it in manually. But when the field is filled through code, the javascript doesn't get triggered and the text doesn't get spaced out.

How can I trigger the on focus action event or the javascript programmatically?

example code

Code: Select all

        Private Shared Sub fill()
            Dim pdf As New Spire.Pdf.PdfDocument()
            pdf.LoadFromFile("file.pdf")

            Dim formWidget As PdfFormWidget = CType(pdf.Form, PdfFormWidget)
            Dim field As PdfField = CType(formWidget.FieldsWidget.List(0), PdfField)
            Dim textBoxField As PdfTextBoxFieldWidget = CType(field, PdfTextBoxFieldWidget)
            textBoxField.Text = "Las Vegas"

            pdf.SaveToFile("file.pdf")
            pdf.Close()
        End Sub


Attached file shows example of issue.

Hi,

Thanks for your posting.
Please try the following solution.

Code: Select all

  PdfDocument pdf = new PdfDocument();
                pdf.LoadFromFile("..\\..\\Abrechnung_SSL_02_Standard-prod-V3.pdf");
                PdfFormWidget form = pdf.Form as PdfFormWidget;
                if (form.XFAForm != null)
                {
                    List<XfaField> xfafields = form.XFAForm.XfaFields;
                   {
                      for (int i = 0; i < fields.Count; i++)
                     {
                       XfaField field = fields[i];
                       if (field is XfaTextField)
                      {
                        XfaTextField textBoxField = field as XfaTextField;
                       //......
                      }
                   }
                 }
                }

If the issue still exists, please share your pdf file for investigation.

Hi Amy,

Sorry for not replying.
I forgot to mention that I am using the Spire PDF free version 3.2. And it seems it doesn’t have any XFA features in that build. So instead, my solution was to edit the cells on the page open event through Javascript. It works for the most part.
Sorry, I am unable to share the PDF file because my client doesn’t want the form distributed.

Thanks for your help.

Hi,

XFA feature is included in Spire.PDF Pack Version:3.7(trial version). We cannot replicate your issue and resolve it if we don't have your pdf document.

Dear Mike,

Our dev team is working on the issue and has got some progress, but we don't have a launch date of a new version now as we also need some time to do some tests when the case is finished. Anyway, we will inform you immediately when new version is ready.
