如何正确使用jsPDF库

我想将一些div转换为PDF,并且尝试了jsPDF库,但没有成功。看来我不明白我需要导入什么才能使库正常工作。我已经看过这些示例,但仍然无法弄清楚。我尝试了以下方法:

<script type="text/javascript" src="js/jspdf.min.js"></script>

在jQuery之后:

$("#html2pdf").on('click', function(){

var doc = new jsPDF();

doc.fromHTML($('body').get(0), 15, 15, {

'width': 170

});

console.log(doc);

});

用于测试目的,但我收到:

"Cannot read property '#smdadminbar' of undefined"

#smdadminbar身体的第一个div 在哪里。

回答:

您可以按如下方式使用html中的pdf,

步骤1:将以下脚本添加到标题

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

步骤2:添加HTML脚本以执行jsPDF代码

对此进行自定义以传递标识符,或者只是将#content更改为所需的标识符。

 <script>

function demoFromHTML() {

var pdf = new jsPDF('p', 'pt', 'letter');

// source can be HTML-formatted string, or a reference

// to an actual DOM element from which the text will be scraped.

source = $('#content')[0];

// we support special element handlers. Register them with jQuery-style

// ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)

// There is no support for any other type of selectors

// (class, of compound) at this time.

specialElementHandlers = {

// element with id of "bypass" - jQuery style selector

'#bypassme': function (element, renderer) {

// true = "handled elsewhere, bypass text extraction"

return true

}

};

margins = {

top: 80,

bottom: 60,

left: 40,

width: 522

};

// all coords and widths are in jsPDF instance's declared units

// 'inches' in this case

pdf.fromHTML(

source, // HTML string or DOM elem ref.

margins.left, // x coord

margins.top, { // y coord

'width': margins.width, // max width of content on PDF

'elementHandlers': specialElementHandlers

},

function (dispose) {

// dispose: object with X, Y of the last line add to the PDF

// this allow the insertion of new lines after html

pdf.save('Test.pdf');

}, margins

);

}

</script>

步骤3:添加身体内容

<a href="javascript:demoFromHTML()" class="button">Run Code</a>

<div id="content">

<h1>

We support special element handlers. Register them with jQuery-style.

</h1>

</div>
