在 JavaScript via C++ 中將 PDF 轉換為 PDFA。快速。簡單。無外部依賴。

    var ffilePdfConvertToPDFA = function (e) {
    const file_reader = new FileReader();
    file_reader.onload = (event) => {
      /*convert a PDF-file to PDF/A(1A) and save the "ResultConvertToPDFA.pdf"*/
      /*during conversion process, the validation is also performed, "ResultConvertToPDFA.xml"*/
      const json = AsposePdfConvertToPDFA(event.target.result, e.target.files[0].name, Module.PdfFormat.PDF_A_1A, "ResultConvertToPDFA.pdf", "ResultConvertToPDFA.xml");
      if (json.errorCode == 0)
      {
        document.getElementById('output').textContent = json.fileNameResult + "\nLog file (xml format): " + json.fileNameLogResult;
        /*make a link to download the result file*/
        DownloadFile(json.fileNameResult, "application/pdf");
      }
      else document.getElementById('output').textContent = json.errorText + "\nLog file (xml format): " + json.fileNameLogResult;
      /*make a link to download the Log (xml)*/
      DownloadFile(json.fileNameLogResult, "application/xml");
    };
    file_reader.readAsArrayBuffer(e.target.files[0]);
  };
