Question

我如何在不重写每一页的所有内容的情况下将以jspdf-object创建的数据重用到同一pdf文档中的其他页面？我也只需要在每一页上调整一行。以下是Se评论。

$("#pdfBtn").on('click', function(){

  var doc = new jsPDF();
  doc.text(5, 5, 'Specific text for page 1');
  // Reusable data
  doc.text(5, 10, 'This is reusable text');
  doc.text(5, 15, 'More reusable text');

  doc.addPage();
  doc.text(5, 5, 'Specific text for page 2');
  // Here i want to reuse the data from page 1

  doc.addPage();
  doc.text(5, 10, 'Specific text for page 3');
  // Here i want to reuse the data from page 1
});

找到了解决方案。只需创建一个包含数据的函数，然后在每个新页面中调用它即可。

Stream<int> debounce(
    Stream<int> source, Duration limit, int combine(int a, int b)) async* {
  int prev;
  var stopwatch;
  await for (var event in source) {
    if (stopwatch == null) {
      // First event.
      prev = event;
      stopwatch = Stopwatch()..start();
    } else {
      if (stopwatch.elapsed < limit) {
        prev = combine(prev, event);
      } else {
        yield prev;
        prev = event;
      }
      stopwatch.reset();
    }
  }
  // If any event, yield prev.
  if (stopwatch != null) yield prev;
}

重复使用jspdf数据
