我想将我的一些div转换为PDF格式,我试过jsPDF库,但没有成功。我试过以下内容:

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

jQuery:

$("#html2pdf").on('click', function(){
    var doc = new jsPDF();
    doc.fromHTML($('body').get(0), 15, 15, {
        'width': 170
    });
    console.log(doc);
});

出于测试目的,但我收到:

"Cannot read property '#smdadminbar' of undefined"

第1步: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>

第2步:添加HTML脚本以执行jsPDF代码

 <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>

第3步:添加body

<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>
