我正在尝试使用itext将javascript添加到pdf中，然后将其与另一个pdf合并 . 但最终合并的pdf不包含javascript . 如果pdf没有与另一个pdf合并，则javascript工作正常 .

Merging code : FileOutputStream sectionR = new FileOutputStream（RESULT）;

PdfCopyFields copier = new PdfCopyFields(sectionR);

 for (String curInPath : listFile) {

       PdfReader reader = new PdfReader(curInPath);
        copier.addDocument(reader);

      }

   copier.close();

我试图将JS添加到生成的合并pdf中，但它没有接受它 . 我猜它不可编辑 .

Below is the code adding JS to pdf which is not merged yet.

FileOutputStream section1Pdf = new FileOutputStream("newPDFSection");

PdfReader readerSection1 = new PdfReader("Existing PDF - Section 1");

PdfStamper stamperSection1 = new PdfStamper(readerSection1,section1Pdf);

stamperSection1.addJavaScript(
"var nameField = this.getField('txtOwnerCity');" +              "nameField.setAction('Keystroke'," +"'forceUpperCase()');" +
      "" +"function forceUpperCase(){" +
"if(!event.willCommit)event.change = " +
"event.change.toUpperCase();" +
"}");

当我尝试将JS添加到生成的合并pdf时，它不允许我说它不再可编辑 .

这就是我想要添加的方式

FileOutputStream sectionR = new FileOutputStream(RESULT);

            PdfCopyFields copier = new PdfCopyFields(sectionR);


            for (String curInPath : listFile) {

                PdfReader reader = new PdfReader(curInPath);
                copier.addDocument(reader);             
}
copier.close();

PdfReader readersectionResult = new PdfReader("result.pdf");

PdfStamper stamper = new PdfStamper(readersectionResult, new FileOutputStream("newResult.pdf"));

stamper.addJavaScript(some JS);

我得到的错误是'警告：无法设置 Headers . 响应已经提交 . '

我不确定我是否正在上面这样做，我想要做的就是得到pdfstamper得到的pdf来添加新的JS .

When I am trying to edit form filed values, it says not editable anymore.

AcroFields acro =压模.getAcroFields（）;

acro.setField（“txtOfficerName”officerChar，officerSO.getFullName（））;
