Question

我正在尝试使用jspdf将div元素打印为pdf。但是它给了我保证金错误。我不确定我要去哪里。我添加了边距，但是它排在了贝伊行的前面，并且缺少我编写的CSS。根据要求，我还添加了HTML代码。

下面是我写的js

margins = {
  top: 70,
  bottom: 40,
  left: 30,
  width: 550
};

 function genIdCards(){
    var pdf = new jsPDF('p', 'pt', 'a4');
    pdf.setFontSize(18);
    pdf.fromHTML(document.getElementById('id-card'), 
        margins.left, // x coord
        margins.top,
        {
          // y coord
          width: margins.width// max width of content on PDF
        },function(dispose) {
          pdf.save('Test.pdf');
        }, 
        margins);
};
<script src="https://unpkg.com/jspdf@latest/dist/jspdf.min.js"></script>
<button onclick="genIdCards()">Generate PDF</button>

CSS

.id-card {
        height: auto;
        float: left;
        background: #fff;
        width: 500px;
        margin: 40px;
        border: 1px solid #7c0000;
    }

.apeejay-school {
    height: 97px;
    width: 100%;
    background: #7c0000;
}

.logo {
    width: 20%;
    height: auto;
    float: left;
    text-align: center;
}

.logo img {
    margin-top: 8px;
}

.apeejay-school-content {
    width: 75%;
    height: auto;
    float: left;
    padding-left: 10px;
    text-align: center;
}

下面是html

Answer 1

从pdf.save()中移出function(dispose){}，以下是工作中的

margins = {
  top: 70,
  bottom: 40,
  left: 30,
  width: 550
};

function genIdCards() {
  var pdf = new jsPDF('p', 'pt', 'a4');
  pdf.setFontSize(18);
  pdf.fromHTML(document.getElementById('id-card'),
    margins.left, // x coord
    margins.top, {
      // y coord
      width: margins.width // max width of content on PDF
    },
    function(dispose) {
      pdf.save('Test.pdf');
    },
    margins);


};

#id-card {
  height: auto;
  float: left;
  background: #fff;
  width: 500px;
  margin: 40px;
  border: 1px solid #7c0000;
}

.apeejay-school {
  height: 97px;
  width: 100%;
  background: #7c0000;
}

.logo {
  width: 20%;
  height: auto;
  float: left;
  text-align: center;
}

.logo img {
  margin-top: 8px;
}

.apeejay-school-content {
  width: 75%;
  height: auto;
  float: left;
  padding-left: 10px;
  text-align: center;
}

Answer 2

我为您写了可行的解决方案。您不必更改pdf.save('Test.pdf');

的位置

var margins =
{
    top: 70,
    left: 30,
    right: 30,
    bottom: 40,
    width: 550
};

function genIdCards()
{
    var pdf = new jsPDF('p', 'pt', 'a4');
    //pdf.setFontSize(18);
    pdf.fromHTML(document.getElementById('idhtml'),
        margins.left, // x coord
        margins.top,
        {
            // y coord
            width: margins.width // max width of content on PDF
        },
        function(dispose)
        {
            //headerFooterFormatting(pdf, pdf.internal.getNumberOfPages());
            pdf.save('Test.pdf');            
        },
        margins
    );
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.4.1/jspdf.min.js" crossorigin="anonymous"></script>

<ul id="idhtml">
	<li>Some text 1</li>
	<li>Some text 2</li>
	<li>Some text 3</li>
</ul>
<button onclick="genIdCards()">Generate PDF</button>

编辑：

您的问题更改后，我已尝试为您找到新的解决方案。不幸的是，jsPDF不支持CSS。仅支持简单的HTML。但是我为您编写了没有CSS的新解决方案：

请在codepen.io上执行 this snippet 并查看PDF。

HTML无法使用JSPDF传输到PDF
