Question

我正在尝试将“页码x of y”添加到使用jspdf和jspdf-autotable生成的PDF中。我在jspdf-autotable示例站点上使用了examples.js文件中的代码，还使用了该网站中包含putTotalPages函数的jspdf.debug.js文件。

我在每个页面上得到的结果是第一页上的“第1页{total_pages_count_string}”和第二页上的“第2页{total_pages_count_string}”，即total_pages_count_string似乎没有正确更新。

我的整个代码如下：

$('#print').click(function() {
            $('#html-table table').remove();
            var table = $("#amu-whiteboard").tabulator("getHtml");
            $('#html-table').append(table);
            $('#html-table>table').attr("id", "table");
            $('#table th:not(:nth-child(1), :nth-child(2)), #table td:not(:nth-child(1), :nth-child(2))').remove();
            var columns = ["Bed", "Name", "Diagnoses", "Jobs"];
            var doc = new jsPDF('l', 'pt');
            doc.setFont('Helvetica', 'normal');
            doc.setTextColor(40);
            var dateTime = moment().format('HH:mm on MMMM Do, YYYY');
            var printedOn = "Printed at " + dateTime;
            var totalPagesExp = "{total_pages_count_string}";
            var pageContent = function(data) {
                doc.setFontSize(14);
                doc.text(21, 30, "AMU Handover Sheet");
                doc.setFontSize(10);
                doc.text(printedOn, doc.internal.pageSize.width / 2, 30, 'center');
                var str = "Page " + data.pageCount;

                if (typeof doc.putTotalPages === 'function') {
                    str = str + " of " + totalPagesExp;
                }
                doc.text(str, doc.internal.pageSize.width - 20, 30, 'right');
            };
            if (typeof doc.putTotalPages === 'function') {
                doc.putTotalPages(totalPagesExp);
            }
            var elem = document.getElementById("table");
            var res = doc.autoTableHtmlToJson(elem);
            doc.autoTable(columns, res.data, {
                addPageContent: pageContent,
                theme: 'grid',
                tableLineWidth: 0,

                }
            });
            doc.save("table.pdf");
        })

有人可以说明我的错误吗？

我认为必须在自动调整后调用putTotalPages()。

putTotalPages在jspdf-autotable标头中不起作用
