javascript - 当页面中的数据已满时，JSPDF切换到新页面

Answer 1

问题在于函数中的条件createCard。您必须更改对 y 偏移的实际当前值的测试。

var data = [{
      "Name": "Ronan",
      "Email": "sodales.elit@eratSed.co.uk",
      "Company": "Malesuada Malesuada Ltd"
    }, {
      "Name": "Calvin",
      "Email": "amet.nulla@Vestibulumante.ca",
      "Company": "Donec Egestas Foundation"
    }, {

    var doc = new jsPDF('p', 'pt', 'a4');
    //Dimension of A4 in pts: 595 × 842

    var pageWidth = 595;
    var pageHeight = 842;
    var y=500;
    var pageMargin = 10;

    pageWidth -= pageMargin * 2;
    pageHeight -= pageMargin * 2;

    var cellMargin = 5;
    var cellWidth = 250;
    var cellHeight = 60;

    var startX = pageMargin;
    var startY = pageMargin;

    function createCard(item) {

      // doc.getTextDimensions(item.Name); turncate or split string if you needed

    if (startY >= pageHeight)
{
  doc.addPage();
  startY = pageMargin  // Restart height position
}

      doc.text(item.Name, startX, startY);
      doc.text(item.Email, startX, startY + 20);
      doc.text(item.Company, startX, startY + 40);

      var nextPosX = startX + cellWidth + cellMargin;

      if (nextPosX > pageWidth) {
        startX = pageMargin;
        startY += cellHeight;
      } else {
        startX = nextPosX;
      }

    }


    for (var i = 0; i < data.length; i++) {
      createCard(data[i]);
    }

使用“startY”并添加1000，它会自动推送到新页面

doc.autoTable({html:"#exportfrontpageTable",startY:doc.autoTable.previous.finalY + 1115});
