当页面中数据已满时，JSPDF 转移到新页面

Question

我是 JSPDF 的新手，正在创建这样的 PDF 页面 Now Problem is that when data is full on this page it didn't produce new page. I have that github 以及堆栈溢出的其他解决方案。但没有得到解决方案。 [JSPDF 演示 link 在这里][3]

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"
    }, {
      "Name": "Kane",
      "Email": "Duis.mi@consectetueradipiscingelit.net",
      "Company": "Arcu Institute"
    }, {
      "Name": "Kasper",
      "Email": "magna.Phasellus.dolor@velconvallisin.co.uk",
      "Company": "Tempor LLP"
    }];
    
    
    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 (y >= pageHeight)
{
  doc.addPage();
  y = 0 // 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]);
    }

Answer 1

问题出在函数 createCard 的条件中。您必须更改对 y 偏移量的实际当前值的测试。

看到这个 fiddle : https://jsfiddle.net/jodfkz59/8/

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"
    }, {
      "Name": "Kane",
      "Email": "Duis.mi@consectetueradipiscingelit.net",
      "Company": "Arcu Institute"
    }, {
      "Name": "Kasper",
      "Email": "magna.Phasellus.dolor@velconvallisin.co.uk",
      "Company": "Tempor LLP"
    }];


    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]);
    }

Answer 2

使用“startY”加1000，会自动推送到新页面

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

当页面中数据已满时，JSPDF 转移到新页面

JSPDF shift to new page when Data is full in page

javascript

jspdf

jspdf-autotable
