我需要使用jspdf将HTML表格导出为pdf文件。这是我的代码

<script type="text/javascript">
    function demo1() {
        $(function () {
            var specialElementHandlers = {
                '#editor': function (element,renderer) {
                    return true;
                }
            };
         $('#cmd').click(function () {
                var doc = new jsPDF();
                doc.fromHTML($('#htmlTableId').html(), 15, 15, {
                    'width': 170,'elementHandlers': specialElementHandlers
                });
                doc.save('sample-file.pdf');
            });  
        }); 
    }
</script>

也可以使用jsPDF-AutoTable插件。

var doc = new jsPDF('p', 'pt');
var elem = document.getElementById("basic-table");
var res = doc.autoTableHtmlToJson(elem);
doc.autoTable(res.columns, res.data);
doc.save("table.pdf");

代码如下

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

脚本:

<script type="text/javascript">
        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 = $('#customers')[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>

表格:

<div id="customers">
        <table id="tab_customers" class="table table-striped" >
            <colgroup>
                <col width="20%">
                <col width="20%">
                <col width="20%">
                <col width="20%">
            </colgroup>

                    <td>3.49</td>
                </tr>
